Common questions

Answers about this tool

How do I calculate the break-even number of units?
Divide fixed costs for the period by contribution per unit. Contribution per unit is the selling price minus variable cost per unit. This calculator rounds the result up because you cannot sell a fraction of a unit or service.
What if my variable cost is equal to or higher than my selling price?
Each sale contributes nothing toward fixed costs or loses money before fixed costs. There is no finite break-even quantity at those inputs; review your price or direct costs.
Does break-even mean I have enough cash?
No. This is a simple operating estimate. Payment timing, inventory purchases, debt repayments, and other cash movements need a separate cash-flow forecast.
Method

How this estimate works

Break-even units equal monthly fixed costs divided by contribution per unit, where contribution is selling price minus variable cost per unit. The result rounds up to a whole unit and shows the revenue at that whole-unit point. Use one product or service and monthly costs for a useful estimate.

Use this as a planning estimate. Actual profit and cash flow depend on overhead, taxes, discounts, payment timing, and other costs not entered here.
