Profit Margin Calculator

What it does

If you already know the sale price and cost, this gives you the gross profit profile of the transaction — margin, markup, and all.

How the math works

Profit = revenue - cost. Margin = profit / revenue. Markup = profit / cost.

Try it with real numbers

• If an item sells for $120 and costs $68, the gross profit is $52, margin is about 43.33%, and markup is about 76.47%.
• A fast margin check before you start layering on payment fees, tax, shipping, or ad spend.

Good to know

• Rates can vary by country, product type, platform plan, or merchant profile.
• Treat these results as planning estimates and double-check anything critical before you rely on it.
• More related tools for marketplace fees, invoices, and payouts are on the way.
