About this calculator

Use this break-even calculator for a one-product sketch: how many units you must sell so contribution exactly covers fixed costs. It is not a full P&L and it ignores inventory, tax, and mix.

Contribution margin per unit = price − variable cost. Units to break even = fixed costs ÷ contribution margin. Break-even revenue = those units × price. Price must exceed variable cost.

Fixed costs: Costs that do not change with volume in this sketch (rent, salaried staff, and similar).

Price / unit: Selling price of one unit.

Variable cost / unit: Cost that scales with each unit sold.

Units: Units that must be sold to break even (can be fractional).

Revenue: Sales at that volume.
