Estimate the true variable cost of one spa treatment service by combining product use, labor time, disposable supplies, and payment processing. The result separates cost from price so you can review margins without treating revenue as profit. Adjust every assumption to match your own products, staffing arrangement, and checkout fees.
The main result is the estimated variable cost of completing one appointment. Contribution profit is what remains from the listed price before rent, software, marketing, taxes, and other overhead.
This is an operating estimate, not an accounting or tax determination. Include only costs that change with the appointment, and review overhead separately.
Using product cost of $18.00, 75 minutes of labor at $32.00 per hour, $7.50 in supplies, a $145.00 price, and a 2.9% + $0.30 processing fee produces the live estimate shown when the page loads.
Not in this variable-cost estimate. Compare the contribution profit with rent and other fixed overhead separately.
Use a realistic hourly labor value for the owner’s time so the estimate does not treat labor as free.
No. Enter a price consistently before or after tax and handle collected tax according to local rules.
Set both processing fields to zero for a cash transaction with no payment fee.
Contribution margin deducts the listed variable costs only; net profit also reflects fixed overhead and other expenses.
