Profit margin calculator

Margin is profit over revenue; markup is profit over cost. Mixing them up systematically underprices your work. This computes both from the same two numbers so the difference stops being abstract.

Estimate

The formula

Profit = revenue − costs. Margin = profit ÷ revenue. Markup = profit ÷ cost. Same profit, two different percentages; contracts and targets must say which one they mean.

What this ignores

Taxes (margins are pre-tax here) and the difference between gross and net margin: put only direct costs in for gross, everything for net.

FAQ

What is a good profit margin for a freelancer or agency?
Service businesses commonly target 30-50% net margin at the project level; below 20% one bad week erases the profit. Productized or retainer work sustains the top of that range best.
Why does margin vs markup confusion cost money?
Because a client hears 'we add 20%' and you meant a 20% margin, which needs a 25% markup. Priced as markup-20 you silently gave away a fifth of your intended profit.
Should I compute margin per project or per month?
Both, different jobs: per project catches mispriced work while you can still fix the next quote; per month catches overhead creep that no single project shows.
