How to use this calculator
- Enter a markup OR a margin percentage.
- Read the matching value of the other.
How it works
Margin = markup ÷ (100 + markup); markup = margin ÷ (100 − margin). They describe the same profit from different bases — markup is on cost, margin is on selling price.
Worked example
50% markup. = 33.33% margin.
Common mistakes
- Treating markup and margin as the same — a 50% markup is only a 33% margin.
- Entering a margin of 100% or more (impossible — price would be infinite).
