What it does
Margin Calculator shows the whole calculation, not just the answer: every intermediate figure is on screen, so you can check it against your own numbers instead of trusting a single output box.
When you need it
Quoting, invoicing, or checking someone else's arithmetic — the moments where being roughly right costs money, and where the formula is easy to get subtly backwards.
Limits and caveats
Figures are unrounded until the final display, so results will not always match a calculation that rounded at each step. This is a working tool, not tax or financial advice, and local rules may differ. Everything happens in your browser, so the file never leaves your device.

Frequently asked questions
- What's the difference between margin and markup?
- Margin is profit as a share of the selling price; markup is profit as a share of the cost. The same trade gives two different percentages.
