Break-Even Calculator: formula & methodology
Contribution margin per unit = selling price − variable cost. Break-even units = ceil(fixed costs ÷ contribution per unit).
The tool uses your entered values and explicitly labeled assumptions. Final results may be rounded for display, while intermediate arithmetic retains available numeric precision. Verify material, tax, device or platform specifications relevant to your situation.
Worked example
With $1,000 fixed costs, $20 price and $10 variable costs per unit, break-even occurs at 100 units.
Try the example above and then change values to reflect your own project or comparison.
Frequently asked questions
What if variable cost exceeds selling price?
The unit has zero or negative contribution and break-even cannot be reached with more sales under the same assumptions.
What is contribution margin per unit?
The selling price minus variable unit expense. This contributes toward fixed costs and eventually profit.
Can I calculate units for a profit target?
Yes. Enter your target profit to add it to fixed costs before dividing by unit contribution.
