How do I know which med spa treatments are actually profitable?
Start with each treatment, not with the bottom line on your P&L. Profit per treatment is the price the client actually paid, minus the product used, minus what the injector or provider earned on it, minus a fair share of room time and overhead. Most med spa owners know their prices well. Fewer know the other three numbers for each service.
Injectables show why this matters. Botox wholesale runs roughly $400 to $600 for a 100-unit vial, or about $7 to $12 per unit depending on your volume. A typical treatment uses 20 to 40 units, so product alone is often $150 to $400 before anyone is paid. Say you charge $14 a unit and a client gets 30 units. That’s $420 in revenue. At $9 a unit your product cost is $270. Pay the injector a 20% commission and another $84 is gone. You’re left with $66 to cover the room, the front desk, rent, and everything else.
Now put that same client on a membership that takes $2 off per unit. Revenue drops to $360, commission drops to $72, and product cost stays at $270. What’s left is $18. If your overhead works out to $100 per room hour and the appointment takes 30 minutes, that treatment loses about $32 every time it’s booked. Discounts, package pricing, and membership rates all lower the effective price, but product cost doesn’t go down with them. Check whether commissions are paid on full price or the discounted price too, because that changes the math.
None of this automatically means you should stop offering a treatment. Plenty of med spas use injectables to bring in clients who later buy higher-margin services like laser or skincare. That should be a decision you make with the numbers in front of you, not something you discover a year later.
Comparing treatments by room hour also helps. A laser treatment may use almost no product but carry a large equipment payment. A facial might have cheap product and a long appointment. Dividing each treatment’s profit by the time it occupies a room shows which services earn the most from your limited space and staff hours.
The hardest part is usually the data. Booking software records that a treatment happened, but it rarely records how many units or syringes went into it. To cost treatments accurately, you need treatment or charting records combined with your inventory counts. If the units charted don’t match what left the fridge, you have waste, undercharting, or product going missing.
Prepaid packages and memberships add one more wrinkle. Money collected for treatments not yet delivered isn’t revenue yet. Recording it as income when it’s received makes the month of a big package sale look better than it was and later months look worse. It’s one of the first things we correct when a med spa comes to us for medical practice bookkeeping and tax services.
If you’d rather not build this yourself, our treatment profitability service brings inventory, treatment, and commission data together each month and shows profit per treatment after product cost and provider pay. Packages and memberships are tracked separately so your revenue isn’t overstated.

Other Common Questions
How should an optometry or audiology practice track frame, lens, and hearing aid inventory?
Track every frame, lens, and hearing aid by item with its cost, count it on a regular schedule, and record cost of goods sold when the product is dispensed instead of when you buy it. Keep exam revenue separate from product revenue so you can measure optical capture rate and margins on each product line.
Read answerWhat does it really cost to add a therapist to a group practice?
Most owners find that the true first-year cost of a new therapist runs well above the salary. Payroll taxes, benefits, paid time off, malpractice, software, and office space all add to it. The bigger expense is often the months of credentialing and caseload building before the new clinician brings in steady revenue.
Read answerHow should a med spa track injectable and product inventory?
Log every vial and syringe on arrival with lot number, expiration date, and cost, then tie each opened unit to a patient, treatment, and injector. Count regularly, investigate any gap between units purchased and units charted, and record manufacturer rebates as a reduction of product cost.
Read answerDo med spas have to charge sales tax?
Usually on part of what you sell. Medical and aesthetic treatments are generally exempt, but skincare, cosmetics, and other take-home products are taxable in most states. You need a seller's permit wherever you make taxable sales and books that keep product sales separate from service revenue.
Read answerDo functional medicine and integrative clinics have to charge sales tax on supplements?
Often, yes. It depends on the state, whether the practitioner can prescribe, and how the supplements are sold. Shipping supplements to patients in other states can create tax obligations there too.
Read answerI'm an employed physician doing locums or expert witness work on the side. What taxes do I owe?
You owe federal income tax, self-employment tax, and usually state income tax on your net side income, and none of it is withheld for you. Most employed physicians should set aside around 40% of their side profit and pay it through quarterly estimates or extra W-2 withholding.
