Start with solution usage.
If you know the bottle size, bottle cost and average ounces used per appointment, you can estimate both tans per bottle and solution cost per tan.
Then add the small costs that quietly add up.
Disposable garments, barrier cream, prep products, powder, laundry and other consumables can look tiny one at a time. Added across hundreds of appointments, they matter.
Questions, answered
Before you use the number.
Should I include rent in cost per tan?
Rent is usually easier to treat as a fixed monthly cost when you are evaluating overall profitability. This calculator focuses on variable cost per appointment so the result stays useful even when your appointment volume changes.
What if my solution usage changes by client?
Use a realistic average and revisit it periodically. The point is not false precision. The point is to stop treating product cost as unknown.
