Break-Even Point Calculator

Calculate the break-even sales volume from fixed costs, price, and variable cost.

Methodology reviewed 2026-07-27. See our review process.

Formula and method

This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:

  • Break-even units: price<=variableCost ? NaN : fixedCosts/(price-variableCost)

Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.

Examples

  • Example: with Fixed costs = 10000, Price per unit = 50, Variable cost per unit = 30, this calculator returns Break-even units = 500 units.
