A PRACTICAL GUIDE

How to use the Discount Profit Calculator.

A discount changes profit per unit even when volume stays constant. Compare contribution before and after the offer with the same cost assumptions.

Make the workflow fit your task.

Calculate the discounted price and contribution per unit using the same cost assumptions as the original offer. Compare the contribution change and, where meaningful, the volume needed to preserve the original total contribution.

Illustrative input and output · a teaching example, not a live WebAct run

Example input

Price $50, unit cost $30, proposed discount 10%.

Completed example

Discounted price: $45. Profit falls from $20 to $15; equal total profit would require one-third more units under these assumptions.

Decisions and troubleshooting.

Does a ten-percent price discount mean profit falls ten percent?

No. Profit changes relative to the remaining contribution after costs. Calculate both amounts before interpreting the percentage effect.

Why does the required sales increase become extremely large?

The discounted contribution may be very small. Check the cost basis and whether the proposed price leaves a positive contribution.
