How the break-even point calculator works
Contribution per unit = selling price − variable cost. Break-even units = fixed costs ÷ contribution per unit, rounded up.
Check your measurements and assumptions
Assumes constant prices and unit costs. It excludes taxes, financing, capacity limits, product mix and changes in costs at different sales volumes.
Review the estimate before you act
Compare this result with an independent measurement, supplier quote or institution guidance when the decision matters. Confirm that the units and assumptions match the labels above, and update the inputs when the conditions change. Keep a note of the values used so you can reproduce the estimate later. This calculator is a planning aid and does not replace professional, product-specific or local guidance.
How many units do I need to sell to break even?
Divide fixed costs by the contribution per unit and round up to a whole unit.
