Break-Even Calculator
Calculate the units and revenue needed to cover fixed and variable costs.
Find the sales volume that covers your costs.
Enter fixed costs, variable cost per unit, and selling price per unit. Break-even units = fixed costs ÷ (selling price per unit − variable cost per unit). This is a local estimate: your figures stay in your browser and are not tax, accounting, or business advice.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What does break-even mean and what is the formula?
Break-even is the sales level where revenue covers fixed and variable costs. The calculator uses break-even units = fixed costs ÷ (selling price per unit − variable cost per unit).
Why must the selling price be above the variable cost?
Each sale must contribute something toward fixed costs. If the selling price is equal to or below the variable cost, there is no positive contribution margin and this simple break-even calculation has no result.
Do my figures stay in my browser?
Yes. The calculation and copy action run locally in your browser. CodeASystem does not upload or store the figures you enter.
