Break-Even Calculator
Contribution = unit price − variable cost. Units = fixed costs ÷ contribution, rounded up to whole units. Target units include target profit. Revenue uses those whole units. With zero fixed cost, zero units already covers costs; with positive fixed cost and nonpositive contribution there is no finite break-even.
Enter nonnegative decimals up to 1 trillion and 6 decimal places. Decimal point or comma; no grouping, exponent or extra text.

Method and assumptions
Contribution = unit price − variable cost. Units = fixed costs ÷ contribution, rounded up to whole units. Target units include target profit. Revenue uses those whole units. With zero fixed cost, zero units already covers costs; with positive fixed cost and nonpositive contribution there is no finite break-even.
Use one currency and one period. Currency is a label; no conversion. Results use floating-point arithmetic; money displays 2 decimals and percentages up to 4. Taxes and other unentered costs are excluded.

With zero fixed cost, zero units already covers costs; with positive fixed cost and nonpositive contribution there is no finite break-even.
Fixed 100, price 10, variable 5: break-even 20 units and revenue 200. Target profit 50 needs 30 units.

Frequently Asked Questions
The model sells whole units. The displayed revenue therefore covers the rounded unit quantity, not an exact fractional crossing.
Positive fixed costs cannot be recovered with nonpositive contribution. Scenarios still show losses. If fixed costs and target profit are both zero, zero sales already meet the target.
