Profit Calculator
Enter revenue and total costs for a period or a unit economics line. You get dollar profit and margin on sales—before taxes, interest, or allocations.
Profit
How this is calculated
Profit = revenue − total costs. Margin = profit ÷ revenue (when revenue > 0).
Example: revenue $18,000, costs $12,400 → profit $5,600 → margin ≈ 31.1%.

Common questions
Gross or net profit?
This is operating-style “revenue minus costs” only. Depreciation, interest, and tax are not built in unless you fold them into total costs.
Negative margin?
When costs exceed revenue, profit is negative and margin is negative—your inputs signal a loss on that scope.
