Marketing as an investment: the CFO’s questions about clinic marketing, answered with numbers

A CFO judges marketing on three numbers: full patient acquisition cost, 12-month margin and payback period. How to work them out, and when to raise or cut the budget.

Healthcare marketing ROI comes down to three numbers: the full cost of winning a new patient, the margin that patient leaves over a year, and the months needed to earn the spend back. When the margin clearly exceeds the cost and the money returns within months, marketing ROI for clinics becomes a decision you can scale with confidence.

My own view, from many meetings with finance directors at clinics and medical groups, is that most disagreement between finance and marketing is about the method of calculation. This article sets out one method both sides can sign up to, and we at Naqar use it with every practice we work with.

What goes into patient acquisition cost?

Everything spent so that a new patient arrives and attends. Most spreadsheets we see count ad spend alone, which makes the cost look far lower than it is.

The lines that belong in the calculation:

  • Ad spend paid to the platforms: Google, Meta, Snapchat and others.
  • Agency fees, or the salaries of an in-house marketing team with their related costs.
  • Production: shoot days, design and editing.
  • Tools: booking and follow-up systems, subscriptions, and the cost of WhatsApp Business messages.
  • Team time: the share of reception and call-centre hours spent answering new enquiries.

Then divide the total by the number of new patients who actually attended in the same period. Attendance is the condition. A patient who booked and never came used up part of the cost and left no margin.

This is what our tools call patient acquisition cost. It differs from the cost per booking of a single channel, which we explained in our guide to calculating cost per booking from each channel. The channel needs its own number for allocation decisions. The CFO needs the full number for the investment decision.

Patient value: revenue or margin?

Margin. Revenue makes every campaign look profitable, because it includes the doctor's share, consumables, and the cost of the room and equipment.

The academic literature on customer value is built on this basis. Gupta and colleagues, in a November 2006 paper in the Journal of Service Research that remains one of the most cited references on the subject, define customer lifetime value as the present value of all future profits a customer generates over the relationship. The key word is profits.

In a clinic, the margin on one visit is what the patient or insurer pays, minus the doctor's share, consumables and the direct cost of the session. Multiply it by the number of visits expected over 12 months.

Why 12 months? Because it is a period a CFO can check against the records. A five-year value helps planning, but it rests on assumptions about patients returning that are hard to prove in the first year of any plan.

Payback period: how do you work it out, and what is reasonable?

The payback period is the number of months until a patient's cumulative margin covers the cost of winning them. No single figure suits every specialty, because visit patterns differ completely.

Illustrative example, in round numbers with no currency. A physiotherapy centre spends 100 units a month on marketing, across all the lines above. It gains 20 new attending patients, so acquisition cost is 5 units per patient. A patient attends 8 sessions on average over two months, and each session leaves a margin of 1 unit. Month one returns 4 units, and month two brings the total to 8. Payback happens during month two, and the patient leaves 3 net units after that, before any later return or referral.

Now take a dental implant clinic. A patient may take weeks between enquiry and decision, then pay a large amount in stages. Payback may look short on paper, but the cash arrives late. Here the CFO cares about cash flow more than the final return.

What is reasonable? At Naqar we agree a maximum payback period with each practice before we start, based on its specialty and cash position. A practice with thin margins and limited cash picks a short limit. A group with reserves accepts a longer one in exchange for faster growth. What matters is that the limit is written down, so every later budget decision becomes a comparison with an agreed number.

How much should a medical practice spend on marketing as a share of revenue?

The most quoted reference is Gartner's CMO Spend Survey. In the May 2025 edition, covering 402 marketing leaders in North America and Europe, marketing budgets averaged 7.7% of company revenue, and about 21% of that went to agencies.

That figure describes large companies in other markets and every sector. It does not transfer to a clinic in Riyadh or Cairo as it stands.

The main reason is capacity. A doctor's weekly hours are close to fixed. A practice running at 90% of its appointment slots gains far less from extra marketing than one running at 60%. So at Naqar we build the budget from the other end:

  1. How many empty slots do you have each month, per doctor and service?
  2. How many of them do you want to fill with new patients?
  3. What acquisition cost will you accept for each service, given its margin?
  4. Budget = patients needed × acceptable acquisition cost.

The share of revenue then falls out of the calculation. It is a starting point the first months will test, reviewed every month against actual figures.

How should a CFO treat content and brand, which pay back slowly?

As a separate line, with its own measures and a quarterly review.

The UK's Institute of Practitioners in Advertising publishes Binet and Field's analysis of the balance between brand building and short-term activation. On the page updated on 30 March 2026, current analysis points to just over 60% of budget on brand building and a little under 40% on activation, with variation by category. The data does not come from healthcare, but it explains why content is hard to judge on a monthly cost per booking.

Illustrative example: a dermatologist posts a weekly video answering a question she hears in clinic. In the first month, not one booking may be traced to those videos. Six months on, patients start calling and asking for her by name.

Measures that fit this line:

  • The number of new patients who ask for a specific doctor by name.
  • Searches for the practice's or doctor's name on Google, from Search Console.
  • The share of new patients who answer "how did you hear about us?" with content or a recommendation.

Give this line a fixed share of the budget and judge it every quarter. Keep it through the first weak month.

The ad platform says one number and the booking system another: which is right?

The booking system, for the financial decision. The platform knows who clicked or started a conversation. The booking system knows who attended and what they paid.

The gap between the two widens in health advertising, because the platforms restrict the health data they accept. We covered this in our article on Meta ads for clinics in 2026.

A good CFO asks a deeper question: would this patient have come without the ad? This is called incremental effect. Ad platforms offer some accounts tests that compare a group that sees the ad with a group that does not. In January 2025 Google made Meridian, its open-source marketing mix model, available to all advertisers. These tools help groups with large budgets. A single clinic can run a simple test instead: pause one channel in one area for a few weeks and watch bookings there against other areas.

When should you raise the marketing budget, and when should you cut it?

Raise it while the cost of each additional patient is below that patient's margin and you still have empty slots. Cut it when the cost of the additional patient approaches the margin, or when the slots fill up.

The key word is "additional". The first money spent in any channel reaches the people closest to booking. Each increase after that reaches people further away, so it costs more.

Illustrative example. A clinic spends 100 units a month and gains 20 patients, or 5 units per patient. It raises spend to 130 units and gains 23 patients. The new average is just under 5.7 units and looks acceptable. But the extra 30 units brought only 3 patients, which is 10 units per additional patient. If a patient's margin is 8 units, the increase loses money even though the average looks fine.

That is why at Naqar we ask that every budget increase is a single step, measured until its result settles in the booking records before the next. The decision rests on the cost of the additional patient.

How do you read a marketing agency's invoice?

Ask for the invoice to be split into four clear lines:

  1. Fees: payment for the agency's work, including planning, management and reporting.
  2. Ad spend: the amount that reaches the platforms. The CFO is best served when it is paid from the practice's own card directly to the platform, so it shows in the ad account.
  3. Production: shoot days and design, by number of assets delivered.
  4. Tools and messaging: subscriptions and the cost of WhatsApp Business messages.

When these lines blur, you cannot tell whether costs rose because platforms became more expensive or because fees went up. The split also makes it easier to compare different working models, which we set out in our article on the marketing company vs growth company difference.

If the question is an outside company versus an in-house team, our in-house team or agency tool works it out with salaries and tool costs you can adjust. Our package ranges are on the healthcare marketing pricing page.

What does insurance change in the calculation?

It changes the margin and the timing of cash. An insured patient may pay a contracted price below the cash price, and the money arrives weeks after the visit. So calculate the margin of insured and cash patients separately, and set an acceptable acquisition cost for each.

In Saudi Arabia, the size of this segment depends on the number of people with private cover, which we covered in our article on privately insured patients in Saudi Arabia. In Egypt, Universal Health Insurance is expanding governorate by governorate, and we explained its effect on private practices in our article on the second phase of Universal Health Insurance.

The CFO's dashboard: 6 numbers each month

This is the dashboard we suggest for a monthly meeting of no more than half an hour:

  1. Total marketing cost, in its four lines.
  2. New patients who attended, from the booking system.
  3. Acquisition cost per attended patient: number 1 ÷ number 2.
  4. Expected 12-month margin per patient, for each main service, updated quarterly from the records.
  5. Payback period in months, against the agreed limit.
  6. Share of slots filled, per doctor or service, because it decides whether an increase helps at all.

Six numbers are enough for next month's decision. Anything beyond them goes in an appendix for the marketing team.

In practice

Ask your team to work out number 3 for the last three months with every cost line included, then compare it with the figure you have been using. The difference is the size of what was missing from the decision. If you want us to build and run this dashboard with you, our Growth Strategy & Management service starts there. For what the 2026 surveys say about company returns from AI, read our article on CEOs and AI. For my part, I find that a practice which agrees the method settles half its budget debates before they start.

Common questions

How do you calculate healthcare marketing ROI for a clinic?

Healthcare marketing ROI compares the full cost of winning a new patient with the margin that patient leaves over 12 months. Acquisition cost covers ad spend, fees, production, tools and team time, divided by new patients who attended. Margin is what remains after the doctor's share, consumables and direct costs. When the margin exceeds the cost, the marketing is earning a return.

What payback period is reasonable for clinic marketing?

No single figure suits every specialty. The payback period is the number of months until a patient's margin covers the cost of winning them. A physiotherapy clinic with repeat sessions may pay back within two months, while a dental implant clinic waits longer for staged payments. The key step is agreeing a written maximum before starting, and checking every later budget decision against it.

What share of revenue should a clinic spend on marketing?

The most quoted reference is Gartner's CMO Spend Survey (May 2025): 7.7% of revenue on average, among large companies in North America and Europe across all sectors. A clinic is limited by its doctors' capacity, so its budget is built from the number of empty slots and the acceptable acquisition cost per service, and the share of revenue follows from that calculation.

When should a clinic raise its advertising budget?

A clinic should raise it while the cost of each additional patient stays below that patient's margin and there are still empty slots. An additional patient usually costs more than the average, because new spend reaches people further from deciding to book. So the budget rises one step at a time, and each step is measured until its result settles before the next.

Why do ad platform figures differ from a clinic's booking records?

The platform knows who clicked or started a conversation, while the booking system knows who attended and what they paid. The gap widens in health advertising because platforms restrict the health data they accept. Financial decisions rest on booking and attendance records, and platform figures are used to understand reach and engagement.
