A slow month is coming. Somebody suggests a promotion. Half off the first treatment, get them in the door, they will come back.
Sometimes that is right. Usually it is a decision made on price when it should be made on margin, and the two are not close to the same thing.
Discounting does not cost you the discount
This is the part that catches people.
If your treatment is priced at four hundred and your margin on it is a hundred and sixty, then a fifty percent discount does not cut your take by half. It takes two hundred out of a hundred and sixty of margin. That treatment now loses money before anybody has walked out the door.
Which means the promotion is not "less profit per client". It is negative profit per client, paid for by volume you may not physically be able to deliver.
Add a deal site taking a cut of what remains and it gets worse from there.
See what the discount costs you
Put in your normal price, your margin and the discount you are considering. It shows how much extra volume that discount has to produce just to break even, which is usually the moment the idea dies.
Your numbers
What that means
Same discount, same volume, twelve months.
Month 1: $600. By Month 12: $7,200.
To make back one 10% discount you have to sell 0.50 more jobs at full price.
Add value instead of cutting price. A free add-on costs you cost. A discount costs you profit.
What this assumed

This is an estimate
This tool returns an estimate based on the numbers you entered. Your real result depends on your own costs, rates and conditions. Check it against your own records before you make a decision with it.
How to run it, step by step
- 1Use your real treatment price. The price a normal client pays, not your package rate and not your introductory rate. If most people already come in on a promotion, use that instead, because that is your real price.
- 2Put in your true margin on that treatment. Take out product, consumables, the provider's time or commission, and the room. What is left is the margin the discount comes out of. Med spa margins vary hugely by treatment, so do this per service.
- 3Enter the discount as offered. If it is a deal site, include their cut. Fifty percent off with the platform taking half of what remains is not a fifty percent discount, and that distinction is the whole ballgame.
- 4Look at the volume it demands. The tool tells you how many more treatments you need to sell to end up where you started. Ask yourself honestly whether your schedule can even hold that many.
How to read what it gives you
- The break-even volume is usually far higher than people expect. That is the point. Discounting does not cost you the discount, it costs you the margin, and margin is a much smaller number than price.
- If the required volume is more than your rooms and providers can physically deliver, the promotion cannot work no matter how many people buy it.
- Run it against a smaller discount with a condition attached, like a package or a rebooking. Almost always beats a deep discount with no strings.
The tool is free, it does not expire, and you can put it on your own website if you want it there. Nothing on this page is locked.

The capacity trap
Run the number and you get a required volume. Now compare it to reality.
You have a certain number of rooms, a certain number of provider hours, and a certain number of appointment slots in a week. If the break-even volume needs more treatments than your schedule can hold, the promotion cannot work. Not "might not". Cannot.
Worse, a full calendar of discounted appointments blocks the full-price clients who would have booked anyway. That is the hidden cost nobody puts in the spreadsheet: you did not just discount the new clients, you displaced the profitable ones.
What actually fills a slow month
Go to the list you already have. Your past clients are the cheapest bookings available and most practices barely contact them. A message to people who already paid you full price once beats a stranger at half price.
Bundle instead of cutting. Three sessions at a package rate raises the total spend and locks in the return visit. The client gets a real deal, you get committed revenue, and your per-visit margin holds up far better than a fifty percent giveaway.
Add, do not subtract. Include a smaller complementary treatment rather than cutting the headline price. It costs you the margin on the add-on, not the margin on the main service, and it feels bigger than it costs.
Discount the time, not the treatment. A modest price break on the Tuesday two o'clock slot that never fills is a completely different decision from a blanket promotion. You are selling capacity that was going to be worth zero.
If you run a promotion anyway
Decide the acquisition cost before you launch, and treat the discount as exactly that. Cap the number of redemptions. Put an expiry on it. Have the rebooking conversation before they leave the room, not in an email a month later.
And measure what share come back at full price. That single percentage decides whether the promotion was marketing or just a sale, and most practices never find out because nobody wrote it down.
Questions people actually ask
Do deal sites ever make sense?
Sometimes, as a deliberate acquisition cost for a service with strong repeat economics, when you have the capacity to absorb it and a real plan to convert those people to full price. As a way to fill a slow month with no follow-up plan, almost never.
What is better than discounting?
Adding value instead of cutting price. Bundle a smaller add-on, include a follow-up visit, or build a package that raises the total while improving the per-visit price. The client feels the win and your margin survives.
Do discount clients come back at full price?
Some do, and the share that does is the entire economics of the decision. Track it. If you cannot say what percentage of last year's promotional clients booked again at full price, you cannot know whether the promotion worked.
How do I raise prices without losing clients?
Give notice, raise it on new bookings first, and be ready to explain what has changed. In aesthetics, the clients most likely to leave over a modest increase are usually the ones with the lowest lifetime value anyway.
