There is no single number that fits every clinic, but there is a sane place to start. Most healthy med spas put somewhere between seven and twelve percent of revenue back into marketing. A newer clinic fighting for awareness sits at the top of that range or above it. An established clinic with a full book and a steady stream of referrals can sit lower.
That percentage is a starting point, not a law. The real answer comes from your own numbers, so let us build it from there.
Start from what a client is worth, not an industry average
The wrong way to set a budget is to copy what another clinic spends. The right way is to work backward from the value of a client. If a new injectable client is worth two thousand dollars over their first year, you can afford to spend real money to win one and still come out far ahead.
Once you know that number, the budget stops feeling like a gamble. You are not hoping the spend works. You are buying clients at a price that leaves a healthy margin, and you scale the spend as long as the math holds.
Where the money should actually go
A budget thrown entirely at ads is a budget half wasted. The clinics that grow split their spend across three jobs that feed each other:
- Paid advertising to bring new people to the door. This is the engine, usually the largest slice.
- Content and social to build trust so the people your ads reach already feel like they know you.
- The page and the follow up that turn interest into booked treatments, because traffic with nowhere good to land is money lit on fire.
Most owners pour everything into the first slice and wonder why the results feel thin. The other two are what make the first one pay off.
A marketing budget is not an expense you approve once a year. It is an investment you measure every month against the clients it brings through the door.
What a healthy cost per booking looks like
The number that matters is not what you spend in total. It is what it costs you to produce one booked treatment, and how that compares to what the client is worth. If you spend a hundred dollars in ads to book a client who spends a thousand on their first visit and returns for more, you have found something worth feeding.
Track that number from the first month. It tells you far more than impressions, clicks or likes ever will. Everything else is noise dressed up as a report.
When to spend more, and when to stop
The signal to spend more is simple. When your cost per booking is comfortably below the value of a client and your calendar still has room, you are leaving money on the table by holding back. Push the budget and watch the number.
The signal to pause is just as clear. When the cost per booking climbs past the point where the math works, or your team cannot handle another booking without service slipping, you stop scaling and fix the bottleneck first. Growth that outruns your chairs is not growth, it is a bad reputation in slow motion.
The short version
Start near ten percent of revenue if you are growing. Set the budget from what a client is worth, not what a competitor spends. Split it across ads, content and the booking experience. Then judge the whole thing on one number, the cost to produce a booked client, and let that number tell you when to press and when to hold.
