🏷️ Margin / Markup Calculator
Calculate gross margin, markup, profit, and break-even price for products and services.
Margin and markup checks
Validates cost and sale price, then reports gross profit, margin, markup, and break-even price. Margin is profit ÷ sale price; markup is profit ÷ cost.
Scenario comparison
Compare 2 to 5 scenarios with the same deterministic formulas used by this calculator. Edit the JSON assumptions, then export a bounded CSV. No tax-law modeling or financial advice.
Values use USD and display rounding to two decimals. Compare assumptions, not just the largest result.
Sensitivity table
Vary one or two numeric inputs across at most 7 values per axis and 49 cells. Calculations reuse the unchanged formula core.
Planning table only. Results use USD display assumptions, do not model tax law, and are not financial advice.
Why it is useful
It helps compare pricing scenarios, quotes, retail targets, and gross-profit assumptions.
How it works
The browser applies pricing formulas to solve margin, markup, and gross profit.
Best input
Use landed cost if shipping, fees, or platform costs affect profitability.
Business tip
Margin and markup are different percentages. Use the one your reporting system expects.
Privacy note
Pricing calculations happen locally in your browser.
Important limitation
This is a gross-price calculator and does not account for taxes, payment fees, returns, overhead, or cash-flow timing unless you include them.
Quick answers
Are margin and markup the same?
No. Margin is profit divided by sale price; markup is profit divided by cost.
Should I include fees in cost?
Yes if you want a more realistic gross-profit estimate.
Common Use Cases
