Bi-directional gross profit margin and markup calculator. Solves for selling price, gross profit, margin percentage, or markup multiplier from cost and target margins.
Runs entirely in your browser
Margin and markup are related but different, and confusing them leads to underpricing. This calculator converts between the four connected quantities — cost, selling price, gross profit, margin percentage and markup percentage — solving for whichever you are missing from the ones you know.
The key distinction it makes clear: margin is profit as a percentage of the selling price, while markup is profit as a percentage of the cost, so a 50% markup is only a 33% margin. Pricing off the wrong one quietly erodes profit. Being able to enter a cost and a target margin and get the exact selling price removes that error.
It runs in your browser, so your figures stay private. Use it to set prices that hit a target margin, work out the margin a given price delivers, or translate a supplier’s markup into what it means for your bottom line.
