A QUICK GUIDE

How to use this tool

Explore a live selling-price breakdown, compare margin and markup, or work backwards from a target percentage.

Enter your cost and selling price to see live totals and the price breakdown.
Optionally choose a target margin or markup and apply the calculated selling price.
Compare the chart with its table and download the visual or its data.

How this tool works

Profit is selling price minus cost. Margin is profit divided by selling price; markup is profit divided by cost. Targets use cost/(1−margin) or cost×(1+markup). The same unrounded values drive chart and table.

Limits and assumptions

Entered costs and selling prices only. Cost may be zero, but selling price must be positive; markup is undefined at zero cost. Taxes and overheads are not inferred. Native numeric exponent input is accepted. Inputs or percentage results outside finite numeric bounds are rejected; very small displayed values use scientific notation.

Does the visual change the calculation?

The visual and the result table use the same values. A negative profit is shown as a loss.
