Profit margin in HOF: how to calculate it per procedure
A high price is not a synonym for profit. An orofacial harmonization (HOF) clinic can have a full calendar, a generous average ticket and still end the month with nothing left over, because it never knew how much stays from each procedure after costs are paid. The profit margin per procedure answers that question and, along the way, shows where price, discounts and waste are eating into the result.
This guide teaches you how to calculate the contribution margin and the net margin of a treatment, how to allocate fixed costs by chair time, how to see the effect of a discount and how to decide what to do when the numbers do not add up. All the numbers in the examples are fictional. There is no market average here: the right margin is your clinic's, with your costs.
Are margin, markup and profit the same thing?
No, and mixing them up leads to wrong prices.
| Term | What it measures | How it is calculated |
|---|---|---|
| Profit in reais | How much ends up in your pocket | Price minus costs |
| Margin | What fraction of the price becomes profit | Profit divided by price |
| Markup | How much is added to the cost to reach the price | Profit divided by cost |
Hypothetical example: an item costs R$ 100.00 and sells for R$ 150.00. The profit is R$ 50.00. The margin is 33.3% (50 over 150). The markup is 50% (50 over 100). Anyone who wants a "50% margin" and applies a "50% markup" ends up with a lower price than needed.
In practice, work with margin on the selling price. It is the measure that matches what the patient pays and the fees that are also charged on the price.
Which costs go into the calculation for a procedure?
Split them into two groups. This split is the basis for everything.
Variable treatment costs change with every procedure performed:
- product (the part of the syringe, vial or kit that was used, plus the part that was wasted);
- disposable supplies (needles, cannulas, gloves, gauze, antisepsis, anesthetic);
- card terminal fee and installment fee on the amount received;
- taxes charged on the invoice (see Simples Nacional for HOF clinics and service invoices);
- professional commission or revenue share, when there is one;
- cost of a touch-up included in the price, when the clinic offers it.
Fixed costs exist even without treatments: rent, payroll, accountant, software, insurance, cleaning, ongoing marketing, equipment depreciation. They are detailed in fixed and variable costs of the HOF clinic.
How do I calculate the contribution margin?
The contribution margin shows how much each procedure "contributes" to paying for the overhead and generating profit. It is the most useful calculation for comparing procedures and for deciding how much discount you can afford.
- Write down the price charged.
- Add up all the variable costs of the treatment.
- Subtract: price minus variable costs. The result is the contribution in reais.
- Divide the contribution by the price to get the contribution margin in %.
One important note on the product: use the cost of what was actually consumed, plus the average loss. For botulinum toxin, for example, the cost is proportional to the units used, plus the leftover that is usually lost in the vial. See pricing botulinum toxin by area and pricing lip filler.
How do I allocate fixed costs and reach the net margin?
Fixed costs do not belong to a specific procedure, but the chair time it takes up is a fair way to allocate them.
- Add up the clinic's monthly fixed costs (including the owner's draw you need to take out).
- Estimate the productive hours per month, meaning the hours the room is actually treating patients (not the hours the clinic is open).
- Divide: monthly fixed cost divided by productive hours. That is the fixed cost per hour.
- Multiply by the length of the procedure, including preparation, record keeping and room cleaning.
The result is the fixed cost that treatment "takes up". Subtracting it from the contribution gives the procedure's profit before taxes on income, and dividing by the price gives the approximate net margin.
Complete hypothetical example
Fictional values, to show the logic of the calculation.
A clinic charges R$ 1,800.00 for a procedure that uses 1 hour of chair time (with preparation and record keeping). The variable costs:
| Item | Amount |
|---|---|
| Product consumed, with average loss | R$ 520.00 |
| Disposable supplies | R$ 40.00 |
| Card fee (4% of the price) | R$ 72.00 |
| Tax on the sale (6% of the price) | R$ 108.00 |
| Total variable costs | R$ 740.00 |
- Contribution: R$ 1,800.00 minus R$ 740.00 = R$ 1,060.00.
- Contribution margin: 1,060 over 1,800 = about 58.9%.
Now the fixed costs: the clinic has R$ 18,000.00 of fixed cost per month and 120 productive hours. The fixed cost per hour is R$ 150.00.
- Procedure profit: R$ 1,060.00 minus R$ 150.00 = R$ 910.00.
- Approximate net margin: 910 over 1,800 = about 50.6%.
That 50.6% is not free profit for the owner: you still need to set aside taxes on income when they apply, pay the owner's draw (if it was not in the fixed costs) and build a reserve. It is useful for comparing procedures and testing prices.
What happens when you give a discount?
The discount lowers the price, but the treatment costs stay almost the same (the card fee and tax even drop, because they are percentages). The entire discount comes out of profit.
Hypothetical example: with a 10% discount, the same procedure drops to R$ 1,620.00.
| Item | No discount | With 10% discount |
|---|---|---|
| Price | R$ 1,800.00 | R$ 1,620.00 |
| Product and supplies | R$ 560.00 | R$ 560.00 |
| Card fee (4%) and tax (6%) | R$ 180.00 | R$ 162.00 |
| Contribution | R$ 1,060.00 | R$ 898.00 |
| Fixed cost of the hour | R$ 150.00 | R$ 150.00 |
| Procedure profit | R$ 910.00 | R$ 748.00 |
A 10% discount on the price cut profit by R$ 162.00, which is about 17.8% of the original profit. That is why the discount policy needs a defined limit. Read discount requests and, for packages, procedure packages in HOF.
How do I compare margin across procedures?
Margin in % does not tell the whole story. Compare three things:
| Measure | Why look at it |
|---|---|
| Margin % | Shows how efficient the price is relative to cost |
| Profit in reais per procedure | What actually goes into the till |
| Profit per chair hour | Shows which procedure makes the best use of your time |
A procedure with a high margin and a low ticket that takes a lot of time can earn less per hour than another with a lower margin and a higher ticket. And a procedure with an expensive product and high waste may have a low margin % but be the entry point for patients who go on to have other treatments. Cross-check margin against the average ticket in HOF and the patient's return history (see the patient LTV calculator).
What if the margin is low?
Before raising prices, investigate the cause. The levers, in order of frequency:
- Product loss. Opened vials that expire, leftovers thrown away, purchases out of step with the calendar. See injectables inventory in the HOF clinic.
- Discounts without rules. Granted because of insistence, with nothing in return.
- Installments that are too long. The card fee and prepayment eat margin. Simulate it in the installments and fees calculator.
- Treatment time longer than planned. Consultations that run long without charging for the time.
- Outdated pricing. The product cost went up and the price stayed the same. Review it with the price per ml and margin calculator and the guide to pricing per ml.
- No-shows and cancellations. An empty slot is fixed cost with no revenue. See no-shows in the HOF clinic.
What minimum margin should I accept?
Instead of looking for a market percentage, set the minimum margin from your clinic's target:
- Calculate the break-even point: how much the clinic needs to bill to pay all its costs.
- Set the monthly target: break-even plus the desired draw and the reserve. Use the average ticket and monthly target calculator.
- With the number of treatments that fit in the calendar, see what average profit per treatment is needed to get there.
- That average profit is your floor. A procedure below the floor only goes ahead with a justification, such as being an entry point or part of a package.
How do I record and review?
A simple spreadsheet, with one row per procedure and columns for price, variable costs, time, contribution, profit per hour and margin, is enough. Review it every quarter, or whenever the product cost, rent or card fee changes. Start with the three highest-volume procedures: they weigh most on the result.
If the clinic uses Harmy, the PDF quote comes out with the value per ml by area, the discount and the validity, which makes it easier to check the price and the discount granted on each proposal. The margin, however, is your own calculation, done with your own costs.
Summary
Profit margin is what is left of the price after variable costs (contribution) and the share of fixed costs the treatment takes up (net margin). Calculate it per procedure, include product loss and fees, allocate fixed costs by chair time, compare profit per hour and set a floor based on break-even and the monthly target. A discount comes straight out of profit, so have a rule for it. Tax, tax regime and owner's draw questions should be confirmed with your accountant.
Frequently asked questions
How do I calculate the profit margin of a facial harmonization procedure?
Add up the costs that change with each treatment (product, supplies, card fee, tax on the sale, commission), subtract them from the price charged and divide the result by the price. That gives the contribution margin. For the net margin, also subtract the share of fixed costs that treatment takes up, usually based on chair time.
How much profit does a filler treatment make at an aesthetics clinic?
There is no single number: it depends on the price charged, the product cost and waste, treatment time, taxes and the clinic's fixed costs. Calculate your own case with your real costs instead of looking for a market average.
What is the difference between contribution margin and net margin?
Contribution margin considers only the variable costs of the treatment and shows how much is left to pay for the overhead. Net margin also subtracts fixed costs and taxes on profit, and shows how much actually stays with the clinic and the owner.
Does giving a discount hurt the margin a lot?
More than it seems, because the costs of the treatment do not fall with the discount. The whole discount comes out of profit in reais, so a 10% discount on the price can reduce profit per treatment by a much larger fraction than 10%.
What profit margin should an HOF clinic have?
There is no right margin for everyone. It has to cover fixed costs, the owner's draw, a reserve and unexpected expenses. Calculate your clinic's break-even point and monthly target, and set the minimum margin from them.
