The formula, explained
Each sale contributes its price less its variable cost toward fixed costs. With fixed costs of 1,000 and a contribution of 20 per unit, 50 units cover those fixed costs. This calculator rounds required units up to the next whole unit.
Example inputs: fixed costs 1,000; selling price per unit 50; variable cost per unit 30. Result: 50 units.
What to check before using the result
This is a single-product model with constant costs and prices. It cannot produce a finite break-even quantity when variable cost equals or exceeds the price. It does not include costs omitted from your inputs.
