Frequently asked questions
- What's the actual difference between margin and markup?
- Markup is profit as a percentage of cost (what you added on top); margin is profit as a percentage of the selling price (what you actually keep). A $40 item sold for $50 has a 25% markup but only a 20% margin. They use the same $10 profit but divide it by different numbers.
- I know my cost and the margin I want. How do I get the selling price?
- Enter your cost and target margin percentage; the tool solves selling price = cost ÷ (1 − margin) for you, so you don't have to rearrange the formula by hand.
- Why does a 50% markup not equal a 50% margin?
- Because markup divides profit by cost while margin divides it by price, and price is always bigger than cost when there's profit. A 50% markup on a $10 cost gives a $15 price, which is only a 33% margin. The gap grows the higher the percentage gets.
