What should a patient enquiry cost? A framework for hospital ad budgets

"What should we be paying per lead?" is the most common question hospital owners ask, and the honest answer is that the number alone is meaningless. A cost per enquiry of ₹250 is excellent for a high-value surgical line and terrible for a routine consultation.

What matters is the relationship between what an enquiry costs and what it is worth. Here is how to work that out for your own hospital.

Start from the value, not the cost

For each service line you want to grow, calculate three numbers from your own records:

1. Average revenue per completed case — not the consultation, the full episode of care where relevant.
2. Enquiry-to-appointment rate — of everyone who contacts you about this service, what share books.
3. Appointment-to-case rate — of those who attend, what share proceeds to the treatment.

Multiply the three and you have the revenue value of a single enquiry. Now you know what you can afford to pay for one — and you will usually find the affordable number is far higher than what you are currently paying, or that a service line you have been promoting cannot economically support paid acquisition at all.

Why costs differ so much by specialty

Three factors drive the spread:

• Competition. Service lines with many private providers in the same catchment cost more per enquiry, simply because more advertisers are bidding.
• Urgency. Emergency and acute needs convert quickly. Elective and planned care involves longer consideration and more comparison.
• Consideration length. Anything expensive, permanent or emotionally weighted takes multiple touches before contact.

This is why a single hospital-wide cost-per-lead target is unhelpful. Budget and benchmark per service line.

Measure conversations, not clicks

Clicks and impressions tell you a campaign is running. They do not tell you whether a patient spoke to your hospital.

Wire campaigns to a measurable endpoint — a WhatsApp conversation, a tracked call, a completed form — and report on cost per conversation. It is a harder number to hit and a far more honest one.

A practical starting split

For a hospital beginning structured paid acquisition:

• Concentrate budget on two or three service lines rather than spreading it across everything.
• Pick lines where you have real clinical depth and spare capacity — filling a department that is already at capacity creates a waiting-list problem, not growth.
• Give each line long enough to produce meaningful data before judging it. Weekly reallocation based on a handful of enquiries is noise-chasing.
• Hold back part of the budget for the landing experience. Sending paid traffic to a slow, unconvincing page is the most common way hospitals waste ad money.

When to stop spending

Paid acquisition is the wrong tool if your enquiry response process is broken, if the service line is at capacity, or if the economics do not work at any realistic cost per enquiry. In each case the money is better spent fixing the underlying problem first.
