See the true profit behind each treatment — per treatment, per hour of chair time, and across the year. Adjust the figures to match your clinic; everything updates instantly.
How to read your numbers
Profit per treatment is your price minus the product, consumables and any staff time for that single treatment. Profit per chair hour is the one to compare across treatments — a lower-priced treatment that's quick can out-earn a premium one that ties up your chair, and this is where you spot it.
The lever you control most is stock cost. Price is capped by your market and time is capped by the day — but your product cost is a choice. Sourcing genuine stock at true trade prices protects the margin on every single treatment you do. That's the number this tool makes visible.
Getting an accurate picture
Use realistic prices and your actual per-treatment product cost. Add your fixed monthly overheads under the optional section to see how many treatments cover your running costs before you're truly in profit. If a treatment is run by an employed injector, add their hourly cost so the per-treatment profit reflects what the clinic keeps.
Frequently asked questions
What's the difference between margin and profit per chair hour?
Margin is profit as a percentage of your price. Profit per chair hour is profit divided by the time the treatment occupies your chair. Two treatments can have the same margin but very different hourly profit — the quicker one earns more per hour, which is what really drives clinic income when your time is the constraint.
What should I include in “product / stock cost”?
The cost of the actual product used in one treatment — for example one vial of toxin, 1ml of filler, or one session's worth of a skin booster. Keep consumables (needles, cannulas, PPE) in the separate field so you can see each clearly.
How does the break-even feature work?
Enter your fixed monthly overheads (rent, insurance, software) in the optional section. The tool divides that by your profit per treatment to show roughly how many of that treatment you need each month before the clinic covers its running costs and moves into profit.
How can I improve a treatment's profitability?
There are three levers: raise the price the market will bear, reduce the time per treatment, or reduce your product and consumable cost. Stock cost is usually the one you control most directly — sourcing genuine product at true trade prices lifts the margin on every treatment.
