Discount impact calculator

See how a percentage discount changes gross revenue at a given volume.

Introduction

Short-term promotions reduce the average fee per session. This calculator compares gross revenue before and after a uniform discount, holding volume constant.

If discounts attract more bookings, adjust the session count separately to model volume effects.

Context and how to use this

Holding volume constant shows the revenue you give up to a promotion. If you expect demand to rise, model volume separately.

Use it in pricing committees when someone suggests a blanket percentage off without estimating margin impact.

Common questions

Why is margin not shown?
Margin needs your variable cost per session. Combine this tool with the session margin calculator if you need contribution impact.
Stacking discounts?
The model applies one percentage to list price. Compound discounts need a different formula.
