How much should a med spa spend on marketing? A straight answer.

Spend what your math supports.

Generic advice says “spend a percentage of revenue.” That number is meaningless without the other half of the equation: what a new client is worth to you. Med spa clients come back — a client won once can mean repeat treatments for years.

Work backwards. Estimate what an average new client spends with you over twelve months. That number tells you what you can afford to pay to acquire one, and that — not a rule of thumb — sets your budget.

Small budgets work when the system does.

You don’t need five figures a month to see results. ACE Performance Gym doubled monthly revenue on $1,500 a month in ad spend — a different industry, but the same lesson: the budget matters less than the machine that catches what the budget generates. A small spend feeding a real funnel beats a big spend feeding a homepage.

Fund the funnel before the brand.

Your first marketing dollars should capture existing demand: campaigns built around one treatment and one offer, a landing page that books, and automated follow-up. Brand content — the polished feed, the aesthetic reels — earns its budget after the conversion machine exists, not before.

Know your cost per booked treatment.

Clicks and impressions are noise. Four numbers tell you whether marketing is working:

• Cost per lead — what you pay for a name and number
• Lead-to-booking rate — how many leads become appointments
• Show rate — how many appointments actually walk in
• Revenue per new client — what each one is worth over time

Multiply those together and you get the only number that matters: what a booked, showed-up treatment costs you. If that number is comfortably below what the client is worth, spend more. If it isn’t, fix the funnel before touching the budget.

Random spend is the most expensive plan.

The costliest budget is the sporadic one: boost a post in March, go quiet until June, try again in September. Ads learn, audiences build and follow-up lists compound — but only if the system runs continuously. Decide what the math supports, commit to it monthly, and judge it on booked treatments.
