How to Calculate Your Patient Acquisition Cost (And Why Most Indian Clinics Don't Know Theirs)

Patient Acquisition Cost (PAC) is the single most important metric that most Indian clinic owners have never calculated. It answers a deceptively simple question: how much does it cost you, on average, to bring one new patient through your door? Hospital marketing departments know this number instinctively. Independent practitioners and small clinic groups almost never do - and this gap costs them far more than any single marketing campaign ever could.

This article introduces PAC as a concept, walks through the standard formula, and then adapts it to the reality of how Indian clinics actually acquire patients: through a mix of physician referrals, Google searches, walk-ins, Practo listings, JustDial leads, and WhatsApp word-of-mouth, most of which are never formally tracked. We then present the MEASURE method - a seven-step data collection process you can implement without any existing analytics infrastructure.

After reading this article, you will know how to calculate your total PAC, how to break it down by channel, how to identify which channels are generating patients at sustainable cost, and which are silently draining your budget. The framework is designed for clinic owners with some business awareness who want to move from gut-feel marketing decisions to evidence-informed ones.

Dr. Priya Menon runs a dermatology clinic in Koramangala, Bangalore. She opened four years ago with a strong referral base from her hospital posting and built reasonable walk-in footfall from the signage on her building and a Practo Premium listing she has maintained since day one. About eighteen months ago, on the advice of a digital marketing agency, she started running Google Ads - initially ₹15,000 per month, now ₹40,000. She also maintains a Facebook page, posts occasionally on Instagram, and is listed on JustDial and Sulekha. Her front desk registers approximately 60 new patients per month, and her existing patient retention is strong.

Last quarter, Dr. Menon's agency sent her a report. It showed 12,400 impressions, 340 clicks, and a "CTR of 2.74%" from Google Ads. What it did not show - what no one in her practice tracks - is how many of those 60 monthly new patients came from Google Ads, how many came from Practo, how many were referred by other doctors, and how many simply walked past and walked in. She is spending roughly ₹55,000 to ₹65,000 per month across all channels. She does not know what she is getting for that spend, because she has never asked the right question at the right moment: "How did you hear about us?"

This scenario is not unusual. It is the norm. Across independent clinics and small clinic groups in India, marketing decisions are made on instinct, peer comparison ("my colleague uses Practo Premium so I should too"), and vendor persuasion. Agency reports provide activity metrics - impressions, clicks, followers - that feel like progress but do not connect to the outcome that actually matters: new patients who book, attend, and pay. The disconnect between marketing expenditure and patient acquisition outcomes is not a failure of intent. It is a failure of measurement.

The deeper problem is that without knowing your PAC by channel, you cannot make rational decisions about where to invest more, where to cut, or whether your total acquisition spend is sustainable relative to the revenue each new patient generates over their lifetime with your practice. A clinic that acquires patients at ₹800 each through physician referrals and ₹4,500 each through Google Ads may be allocating 70% of its marketing budget to the higher-cost channel simply because it produces a dashboard and feels more controllable. That is not a marketing strategy. It is expensive confusion.

The good news is that calculating PAC does not require a CRM system, a data analyst, or a marketing degree. It requires a clear definition, a disciplined data collection habit at the front desk, and about 90 days of consistent tracking. The MEASURE method, introduced in Section 6, is designed to get a clinic from zero analytics to a working PAC calculation in one quarter.

India's healthcare market is overwhelmingly private in the outpatient segment. Sharma et al. (2025), in a peer-reviewed study of 5,061 PM-JAY eligible individuals across seven Indian states (published in Global Health Action, PMC11998304), found that 48.0% sought private outpatient care, compared to only 18.3% who used public facilities, with 23.1% reporting no regular outpatient care at all. These are individuals eligible for government-sponsored coverage choosing to spend out of pocket at private facilities. The competitive pressure on private clinics to attract and retain these patients is therefore intense - and growing. For clinic operators, the implication is not that demand is lacking, but that the competition for it is fiercer than the surface picture suggests.

India crossed 800 million smartphone users in 2024, with a median population age of 29. The average new patient you are trying to acquire is young, smartphone-native, and conducts some form of digital research before booking - even if the final trigger is a friend's recommendation on WhatsApp. A FICCI-EY Parthenon survey of over 1,000 patients and 100 clinicians (October 2025, an industry report rather than peer-reviewed research) found that patients rely heavily on "informal proxies like brand reputation and word-of-mouth" when choosing providers. This combination - social proof as the trust signal, digital search as the discovery mechanism - means that every Indian clinic is now competing across multiple channels simultaneously, whether the clinic owner intends to or not. Channels have costs whether or not they are being managed.

Platform economics matter here. Practo, JustDial, Google Maps, and increasingly WhatsApp referral chains each have distinct cost structures, patient intent profiles, and conversion behaviors. A Practo Premium listing charges a fixed fee regardless of how many patients book through it; Google Ads charges per click; a physician referral network costs relationship time and occasionally formal referral fees; walk-ins cost signage and local visibility investment. None of these channels should be evaluated on the same basis. Treating your Practo spend and your Google Ads spend as undifferentiated "marketing expenses" prevents you from seeing that one may be generating patients at three times the cost of the other - a difference that compounds significantly over a year.

The regulatory environment adds important context. The National Medical Commission (NMC) governs professional conduct and advertising for Indian doctors, restricting certain forms of direct patient solicitation and placing guardrails around claims and testimonials. The Digital Personal Data Protection Act 2023 (DPDPA) creates obligations around how patient contact data - including the source information collected as part of a PAC analysis - is stored, processed, and disclosed. These constraints are real but manageable. They do not prevent measurement; they require that measurement be done responsibly. Any clinic collecting patient source data must ensure its privacy notice covers this use, its storage is secure, and its practices comply with DPDPA obligations.

Private healthcare utilization establishes the competitive baseline. Sharma et al. (2025), published in Global Health Action (PMC11998304), studied 5,061 PM-JAY eligible individuals across Andhra Pradesh, Bihar, Chhattisgarh, Gujarat, Jharkhand, Maharashtra, and Uttar Pradesh. The study found 48.0% private outpatient utilization - a finding from a population specifically eligible for subsidized government care. This establishes that the private outpatient market is large, structurally competitive, and reaching populations traditionally assumed to be public-sector patients. The study does not address acquisition cost directly, but it establishes the scale of the competitive environment in which Indian clinics operate. A market in which even price-sensitive patients with government insurance default to private providers is one in which acquisition economics warrant serious attention.

Patient decision-making relies on informal signals that are difficult to attribute. The FICCI-EY Parthenon survey (October 2025, an industry report surveying approximately 1,000 patients and 100 clinicians; not peer-reviewed, methodology not fully disclosed) found that patients rely on "informal proxies like brand reputation and word-of-mouth" in selecting providers. Treat specific figures from this report as directional rather than rigorous. However, the qualitative finding aligns with longstanding behavioral economics research on how consumers choose professional services under uncertainty: they default to social proof and reputation when they cannot evaluate technical quality independently. For PAC purposes, this means referral channels likely carry high conversion rates and lower per-patient costs, but building referral volume requires investment in relationships that is harder to measure than digital ad spend.

Healthcare PAC benchmarks from the United States are directionally applicable to India. Multiple US healthcare marketing analyses - including figures cited in Medical Group Management Association benchmarking surveys and various specialty-specific industry reports - have found average patient acquisition costs ranging from USD 150 to over USD 1,200 depending on specialty, channel mix, and market. These figures are not directly transferable to India, given vast differences in market structure, price levels, and consumer behavior. However, the directional principle holds: acquisition cost varies enormously by channel and specialty, and paid digital channels frequently underperform relationship-based referral channels on a per-patient cost basis. Indian clinic operators should treat US figures as a structural reference only - never as a benchmark to compare against.

Digital advertising conversion claims in Indian healthcare are not independently verified. Platforms including Practo and Google publish aggregated data suggesting strong conversion performance in the healthcare segment, but these figures originate from the platforms themselves and should be treated as promotional rather than independent evidence. As of mid-2026, there is no peer-reviewed literature establishing verified PAC benchmarks by specialty or clinic size for the Indian market. This gap between platform-reported performance and independent verification is itself a meaningful finding: clinics are being asked to make significant monthly investments based on vendor-supplied metrics that have not been independently audited. This is an argument for internal tracking rather than platform dashboard reliance.

Patient lifetime value (LTV) research in Indian primary and specialist care is limited. PAC calculated in isolation - without reference to the revenue a new patient generates over their lifetime with the practice - produces a number without context. A ₹3,000 PAC may be entirely sustainable for an orthopedic surgeon with long-term rehabilitation patients and a high procedure yield; it may be economically damaging for a general physician with low consultation fees and high patient churn. Published LTV analysis for Indian clinic contexts is scarce. The principle that PAC must be evaluated against LTV is well-established in service business economics globally and is directionally applicable to Indian healthcare. Clinics should estimate their own LTV before drawing conclusions from their PAC figure.

The following section is Influx Health's interpretation and opinion based on field experience, not published research.

Working with more than 60 Indian healthcare organizations - ranging from single-practitioner clinics to multi-specialty groups - we have found that the most common response when we ask a clinic owner their PAC is genuine surprise that we are asking at all. Not because they have calculated it and consider it a private matter, but because the question has simply never occurred to them in those terms. Marketing is typically conceptualized as a fixed overhead - "we pay ₹25,000 a month for digital, that is our marketing budget" - rather than as an investment with a measurable per-patient return. The mental model is closer to rent than to inventory. You pay it because you need to be present; what you get back is not tracked.

The second consistent finding is that when we help a clinic calculate PAC by channel for the first time, the results surprise everyone in the room. Almost without exception, physician referral networks generate the lowest PAC - often below ₹500 per patient - while paid digital channels, particularly Google Ads managed by third-party agencies, generate the highest PAC, frequently ₹2,500 to ₹5,000 or more once all agency fees are factored in. This pattern mirrors what is reported globally. What is striking in the Indian context is that most clinics are actively increasing spend on the high-cost digital channels and passively maintaining - or quietly neglecting - their referral networks, because digital feels more measurable and modern. The referral network produces results that feel organic and untracked; Google Ads produces a dashboard. In most cases, the dashboard wins the budget, even when the referral network wins on PAC.

We also observe that front-desk data collection is the single most critical intervention for PAC analysis - and also the one most consistently skipped. The "how did you hear about us?" question, asked at every new patient registration and recorded in a structured way, generates 90% of the data required for a working PAC calculation. In our experience, clinics that implement this one habit and maintain it for 90 days have enough data to make meaningful channel-allocation decisions. Clinics that rely on platform analytics alone - Google Analytics, Practo dashboards, JustDial reports - are seeing a partial and vendor-curated picture of their acquisition funnel. Each platform reports only what it can attribute to itself.

Finally, we want to flag something the frameworks often understate: the genuinely blended nature of Indian patient acquisition. A patient may discover a clinic on Practo, check Google reviews, receive a WhatsApp recommendation from a family member, and then walk in without clicking any trackable link. Attribution in this environment is inherently incomplete. The goal of PAC calculation is not perfect attribution - it is directional clarity. Knowing that referrals produce roughly 40% of your new patients at roughly 15% of your marketing spend is actionable intelligence, even if the edges are blurry. Waiting for perfect data before acting is, in practice, a decision to never act.

A seven-step process for calculating patient acquisition cost in a clinic with no existing analytics infrastructure.

M - Map Your Acquisition Channels Begin by listing every channel through which a new patient could have found your practice. Common channels for Indian clinics include: physician referrals (from other doctors), patient referrals (word-of-mouth from existing patients), Google organic search, Google Ads, Google Maps listing, Practo (organic or paid), JustDial, walk-in (signage and local presence), hospital discharge referrals, WhatsApp, and social media (Facebook, Instagram). Do not skip channels because they feel informal - walk-ins and WhatsApp referrals are real acquisition channels with real associated costs. The goal at this stage is an exhaustive list, not an assessment. You cannot measure what you have not named.

E - Enumerate All Spend Per Channel, Including Hidden Costs For each channel, calculate your total monthly spend. Include direct costs (Practo subscription fee, Google Ads budget, JustDial listing fee) and indirect costs (agency management fees, staff time spent on social media, time spent on referral relationship-building). A common error is counting only the platform fee and ignoring the agency markup, which can double or triple the true cost of a digital channel. For referral networks, include any formal referral incentives, association event costs, or relationship-maintenance spend. Assign a reasonable estimate even to channels you have not formally budgeted. A ₹0 cost assumption for walk-ins that are supported by ₹8,000 per month of signage and local directory listings is a measurement error, not a discount.

A - Assign a Source Identifier to Every New Patient Starting today, ask every new patient at registration: "How did you hear about us?" Train front-desk staff to record one primary source from your channel list, either in your patient management system or at minimum in a daily paper log. This is the foundation of every channel-specific PAC calculation - without source data at the patient level, you are limited to a blended average that conceals the channel variation you most need to see. Run this consistently for a minimum of 90 days before drawing conclusions. Resist the temptation to rely on platform-reported attribution; always prefer the patient's direct answer, which is the only signal that is channel-agnostic.

S - Separate New Patients from Returning Patients PAC applies only to new patient acquisition, not to total footfall. Your patient management system or front-desk register should flag whether each appointment is a first visit or a return visit. If you do not currently track this, start now alongside your source tracking. Calculating PAC against total patient visits - a common error - significantly understates your true acquisition cost by diluting the calculation across patients you have already acquired and no longer need to pay to bring in. The numerator in the PAC formula is new patients only.

U - Understand Your Blended PAC First Before breaking down by channel, calculate your total (blended) PAC. The formula is: Blended PAC = total monthly acquisition spend across all channels ÷ total new patients per month. This single number is your baseline. It tells you whether your acquisition economics are broadly sustainable before you diagnose channel-specific issues. As a rough directional guideline for independent clinics in India: a blended PAC below ₹1,000 is generally healthy across most specialties; ₹1,000 to ₹2,500 is manageable but warrants review of the channel mix; above ₹2,500 should prompt a channel audit, particularly if average consultation fees are under ₹1,000 and patient visit frequency is low.

R - Run Channel-Specific PAC Calculations Once you have 90 days of source data, calculate PAC for each channel: Channel PAC = total channel spend over the period ÷ new patients attributed to that channel over the same period. Rank channels by PAC from lowest to highest. In our experience, the range between the most and least efficient channels is typically 5x to 10x. This ranking is your prioritization tool. Channels with low PAC should receive attention to maintain volume and, where possible, scale. Channels with high PAC should be evaluated: is the cost justified by patient quality, volume, or LTV? Is the spend being managed actively, or is it on autopilot while the agency collects a management fee?

E - Evaluate Against Patient Lifetime Value PAC without LTV context is an incomplete metric. Calculate a working LTV estimate for your practice using the formula: LTV = average revenue per patient per visit × average visits per year × average years a patient remains active. Even a conservative estimate - ₹800 per visit × 3 visits per year × 4 years = ₹9,600 LTV - gives you a ceiling for sustainable PAC. The general principle from service business economics: PAC should not exceed 10–20% of LTV for a financially healthy practice. If your Google Ads PAC is ₹4,500 and your estimated LTV is ₹9,600, that channel is consuming nearly half the lifetime value of every patient it generates before you have seen any return. That calculation, once made, tends to change budget conversations immediately.

• This week - start recording patient source at registration. Add "How did you hear about us?" as a required field in your new patient intake form or registration log. Create a short list of channel categories for front-desk staff to choose from. Train every person at reception. Do this before anything else; without this data, no channel-specific PAC calculation is possible.

• This week - calculate your total monthly acquisition spend. Sum every rupee going to Practo subscriptions, Google Ads, agency fees, JustDial listings, social media management, referral event costs, association memberships with a patient-acquisition purpose, and signage maintenance. Most clinic owners underestimate this number by 30–50% before doing the exercise formally.

• This month - calculate your blended PAC for the current month. Divide your total acquisition spend by your new patient count this month. Write down the number. This is your baseline. If it surprises you, that surprise is the entire point of the exercise.

• This month - estimate your patient lifetime value. Use conservative assumptions. Calculate your average fee per visit, estimate average visits per year for your patient population, and estimate how many years a patient typically remains active with your practice. Multiply through. Compare to your blended PAC. The ratio tells you whether your acquisition economics are sustainable in principle.

• In 90 days - run your first channel-specific PAC analysis. After three months of consistent source tracking, break down your new patient count by channel. Calculate PAC for each channel. Rank them. Identify your two highest-cost channels and audit whether the spend is generating returns that justify the cost, relative to your lower-cost channels.

• Quarterly - review, compare, and reallocate. Set a recurring calendar reminder to recalculate PAC by channel, compare to the previous quarter, and make at least one deliberate budget reallocation based on the data. Practices that run this process consistently for two to three years develop a materially more efficient acquisition engine than those that manage marketing by instinct and vendor recommendation.

---

Q: My clinic is doing well and I am busy. Do I really need to track this?

A: Being busy is not the same as being efficient. A full appointment book with a high PAC may be growing revenue while simultaneously eroding margins. More importantly, a busy clinic that does not understand its acquisition economics is structurally vulnerable: a Practo algorithm change, a Google Ads price increase, a referring doctor relocating, or a new competitor opening nearby can disrupt patient flow in ways that a clinic with diversified, tracked channels handles far better than one that is dependent on unexamined channel mix. "I am busy" is a reason to understand your PAC sooner, not a reason to defer.

Q: What if I cannot afford a CRM or patient tracking software?

A: You do not need any software to calculate PAC. A paper registration form with a "How did you hear about us?" field and a monthly tally in a spreadsheet is sufficient to run the full MEASURE analysis. The data requirement is genuinely minimal: a count of new patients by source per month and a total spend figure by channel per month. A front desk receptionist with a paper form and a free spreadsheet template can generate the data you need. Start with the simplest possible system and add complexity only when the basic calculation is already running smoothly.

Q: How do I handle patients who came through multiple channels - they saw me on Practo, then Googled me, then a colleague recommended me?

A: Multi-touch attribution is a real and well-documented challenge in any marketing analytics context, and it is particularly pronounced in Indian healthcare given the social and digital signals involved. The practical solution is to ask the patient to name the primary channel - the one that first made them aware of your practice. You will miss some nuance, but you will capture enough signal to make directional decisions about channel allocation. More sophisticated attribution models (first-touch, last-touch, linear weighting) are useful in large-scale settings but are overkill for most independent clinics. Directional clarity from simple first-touch attribution is substantially more valuable than perfect data that never gets collected.

Q: Are there NMC or legal restrictions I need to be aware of when tracking patient source data?

A: Yes, and they are worth taking seriously. Under the Digital Personal Data Protection Act 2023 (DPDPA), patient source data constitutes personal data and must be collected with a lawful basis, stored securely, and used only for purposes disclosed to the patient. Collecting source information as part of clinical registration - for the internal purpose of improving practice operations - is generally lawful, but your patient privacy notice should mention it and your data storage practices must be secure. The NMC's guidelines on advertising focus primarily on public-facing communications rather than internal practice analytics, but any patient-facing acquisition materials (website, Practo profile, Google Ads copy) must comply with NMC professional conduct rules, particularly around claims and testimonials. If you are unsure whether a specific practice is compliant, consult a healthcare regulatory advisor before proceeding.

Q: My Practo dashboard shows detailed analytics. Why should I ask patients directly instead of using those reports?

A: Practo's analytics show what happened on the Practo platform: views, clicks, profile visits, and in some cases appointment requests. They do not tell you whether those patients actually attended, how much they paid, whether they became regular patients, or how they would have described their primary discovery channel if you had asked. Every platform reports conversions it can attribute to itself. Practo over-counts Practo; Google Analytics over-counts Google; JustDial over-counts JustDial. None of them reports the patients who saw your Practo profile, mentioned it to a family member, and then came in when that family member called to book. A patient's direct answer at registration is the only attribution signal that is not filtered through a vendor's measurement interest. Use platform analytics to supplement direct tracking, not to replace it.

Subject line: Dr. [Name], do you know what one new patient costs your clinic?

Dear Dr. [Name],

Here is a question most clinic owners cannot answer: how much does it cost you to acquire one new patient?

Not a rough sense of your marketing budget. The actual number - total spend across all your channels, divided by new patients per month, broken down by source. For most independent practitioners in India, this figure is unknown. When calculated for the first time, it is usually surprising.

Patient Acquisition Cost (PAC) is standard practice in hospital marketing departments. It is almost entirely absent from independent clinic management - not because it is complex, but because no one has introduced the habit. Our latest article for Center 3: Practice Economics closes that gap with a practical formula and a seven-step data collection process called the MEASURE method, designed for clinics starting from zero analytics infrastructure.

Three findings from working with more than 60 Indian healthcare organizations stand out. Physician referral networks almost always produce the lowest PAC - often below ₹500 per patient. Paid digital channels, particularly Google Ads managed by agencies, frequently generate PAC of ₹2,500 to ₹5,000 once all fees are included. And the single most important intervention - asking "how did you hear about us?" at registration and recording the answer consistently - costs nothing and generates the foundation of every channel analysis you will ever run.

The article covers the PAC formula, channel-specific calculations for referral, Google, Practo, and walk-in traffic, and a concrete action checklist for this week and this month. It also covers the DPDPA and NMC considerations that apply to any patient acquisition tracking programme.

Do You Know What One New Patient Costs You? (4-minute read)

Most Indian clinic owners spend ₹20,000 to ₹60,000+ per month on patient acquisition - and cannot say what one new patient actually costs them.

Patient Acquisition Cost (PAC) is a simple calculation:

Total acquisition spend ÷ New patients acquired = PAC

The challenge is knowing your spend by channel and counting new patients separately from returning ones. Most clinics do neither.

The MEASURE method helps clinics with no existing analytics get to a working PAC in 90 days:

1. Map your channels - Google, Practo, JustDial, referrals, walk-ins, WhatsApp
2. Enumerate all spend - including agency fees you may be overlooking
3. Assign a source to every new patient at registration
4. Separate new patients from returning patients
5. Understand your blended PAC first
6. Run channel-specific PAC after 90 days of data
7. Evaluate each channel against your patient lifetime value

One consistent finding across 60+ Indian healthcare organizations: referral networks almost always produce the lowest PAC. Paid Google Ads often produce the highest - sometimes 5–10x more expensive per patient than referrals.

The one action that makes everything else possible: start asking "how did you hear about us?" at every registration, today.

Most Indian clinic owners I speak with cannot answer this question: what does it cost you to acquire one new patient?

Not a rough sense of the marketing budget. The actual number - total spend across all channels, divided by new patients per month, broken down by source.

Hospital marketing teams know this number. They track it quarterly, by channel, against patient lifetime value benchmarks. Independent practitioners and small clinic groups almost universally do not - and this asymmetry has real consequences when budgets get reviewed and channels get evaluated.

Here is what consistently surprises clinic owners when they calculate PAC by channel for the first time: the most "informal" channel - physician referral networks - almost always produces the lowest cost per acquired patient, often below ₹500. The most "measurable" channel - Google Ads with its dashboards and CTR reports - almost always produces the highest cost, frequently ₹2,500 to ₹5,000 once agency management fees are included. Clinics routinely increase spend on the expensive channel because the dashboard feels like evidence. The referral network quietly generates patients at a fraction of the cost, with no dashboard in sight.

The new article from the Influx Health Institute introduces the MEASURE method: a seven-step process for calculating PAC in a clinic starting from zero analytics. It covers the formula, channel-specific calculations for Google, Practo, JustDial, and referral traffic, and a practical checklist you can act on this week.

The one free intervention that makes the entire calculation possible: ask "how did you hear about us?" at every new patient registration. Train your front desk. Record the answer against a fixed list of channels. That single habit, maintained for 90 days, provides the foundation for every channel-allocation decision you will make for the next several years.

1/ Most Indian clinic owners do not know their patient acquisition cost. Not because the calculation is hard. Because no one has told them to do it. A thread on what it is, why it matters, and how to calculate it starting from zero.

2/ Patient Acquisition Cost (PAC) = total acquisition spend ÷ new patients acquired. Simple formula. The challenge is two things: knowing your actual spend by channel, and counting new patients separately from returning ones. Most clinics do neither.

3/ Hospital marketing departments track PAC quarterly by channel. Independent clinics almost never do. This gap means budgets flow to channels that feel measurable, not channels that are actually efficient. A dashboard is not evidence of value. It is evidence of activity.

4/ What we consistently see working with 60+ Indian healthcare organizations: physician referral networks produce PAC below ₹500 per patient. Google Ads managed by agencies often produce PAC of ₹2,500 to ₹5,000+. Most clinics are increasing spend on the expensive channel.

5/ Sharma et al. (2025, PMC11998304) found that 48% of PM-JAY eligible Indians - people who could access free government care - chose private outpatient care instead. The private outpatient market is large, structurally competitive, and reaching populations you might not expect. Acquisition economics matter.

6/ Platform dashboards are not the answer. Practo reports what happens on Practo. Google Analytics reports what it can attribute to Google. Neither tells you what a patient says when you ask "how did you hear about us?" - which is the only channel-agnostic data point in the room.

7/ The one free intervention that makes PAC calculation possible: ask "how did you hear about us?" at every new patient registration. Record it against a fixed channel list. Do this for 90 days. That data is 90% of what you need for a full channel analysis.

8/ Introduce the MEASURE method: Map channels → Enumerate all spend → Assign source to every new patient → Separate new from returning → Understand blended PAC first → Run channel-specific PAC at 90 days → Evaluate against patient lifetime value.

9/ PAC without lifetime value context is a partial metric. A simple LTV estimate: average fee × visits per year × active years. A ₹3,500 PAC means something very different against a ₹6,000 LTV than against a ₹25,000 LTV. Calculate both numbers together.

10/ The new Influx Health Institute article covers the full calculation, channel-specific PAC for Google, Practo, JustDial, and referrals, NMC and DPDPA considerations, and an action checklist for this month.
