What is this markup ⇄ margin converter?
A free, browser-based converter for the markup-vs-margin mix-up. Markup is profit measured against cost; margin is profit measured against price — same deal, different denominator. Enter any of markup %, gross-margin %, cost, or price and the rest is computed live, with the formula shown beside each result. Everything runs locally in your browser, so your numbers are never uploaded.
The formulas
- Markup = (Price − Cost) ÷ Cost (profit relative to cost).
- Margin = (Price − Cost) ÷ Price (profit relative to price).
- Margin = Markup ÷ (1 + Markup) — convert markup to margin.
- Markup = Margin ÷ (1 − Margin) — convert margin to markup.
- Price = Cost × (1 + Markup); Cost = Price ÷ (1 + Markup).
How to use it
- To convert a rate, enter just one of markup % or margin %.
- To back out price or cost, add a cost or a price alongside the rate.
- Enter both cost and price to get the markup and margin directly.
Common use cases
- Translating a supplier's markup into the gross margin your finance team reports.
- Setting a price from a cost and a target markup (or target margin).
- Checking that quoted 'margin' and 'markup' figures actually agree.
