Frequently Asked Questions
Why do discounts hurt margin more than they seem to?
Since discounts are taken off the selling price but your cost stays fixed, a percentage discount eats into your margin at a faster rate than the discount percentage itself — a 20% discount can easily cut your profit margin in half or more, depending on your starting margin.
When is offering a discount still worth it?
Discounts can be worth the margin hit when they drive enough additional volume to offset the per-unit profit loss, clear excess inventory, or acquire new customers who generate future repeat purchases at full price.
Is there a discount level where I'd lose money?
Yes — once the discounted price drops below your product cost, you're selling at a loss on every unit. This calculator shows exactly where your margin turns negative as the discount increases.
