Free solution usage calculator

Turn ounces of solution into a usable inventory plan.

A bottle count is more useful when you can translate it into appointments. Enter how much solution you use and how busy you are to estimate how far your current back bar can actually take you.

Planning estimate only. Results depend on the numbers you enter and do not include every tax, fee, payroll or business expense unless you include it in your inputs.

01

Your usage rate matters more than a universal tans-per-bottle number.

Spray technique, body size, equipment and service style can all change how much solution you use. Your own average ounces per tan will produce a more useful planning number than a generic industry estimate.

02

Use days of supply to avoid emergency ordering.

When you know roughly how many appointments your on-hand solution can cover, you can compare that with your upcoming schedule and supplier lead time instead of waiting until a bottle feels light.

Questions, answered

Before you use the number.

How many spray tans can I get from a bottle of solution?

Divide the usable ounces in the bottle by your average ounces used per tan. The result is an estimate because actual usage can vary from client to client.

Should I wait until I am almost out before reordering?

Usually no. A practical reorder point accounts for upcoming appointments, shipping time and a small buffer for unusually busy weeks or product loss.
