Frequently asked questions
- Why does a small discount have a big impact on margin?
- Because the discount comes entirely out of your profit, not your cost. A 10% discount on a product with 40% margin reduces margin by 6.7 percentage points — a 17% reduction in profitability. The lower your margin, the more damaging each percentage of discount.
- How do I calculate the volume increase needed to offset a discount?
- Volume increase needed = (original margin / new margin) − 1. If original margin is 40% and discount reduces it to 33.33%, you need to sell 40/33.33 = 1.2× as many units — a 20% volume increase — just to maintain the same gross profit dollars.
