Break-even Calculator
Calculate break-even units and revenue from fixed costs, unit price, and variable cost per unit.
Informational planning estimate only — confirm actual costs, taxes, fees, and accounting requirements separately.
Formula: break-even units = fixed costs ÷ (price per unit − variable cost per unit).
Break-even calculator workflow tips
Break-even math is useful before estimating ROI, bundle pricing, campaign targets, or capacity needs. Keep fixed and variable costs realistic so the unit target is useful.
Set the selling price
Use Markup Calculator or Profit Margin Calculator when price per unit still needs a sanity check.
Estimate return after break-even
Use ROI Calculator after you know total costs and an expected return amount.
Compare sale impact
Use Discount Calculator when a promotion lowers price per unit and changes contribution margin.
Example break-even calculation
With 12,000 fixed costs, a 45 price, and 18 variable cost per unit, contribution margin is 27 per unit. Break-even is about 444.44 units and 20,000 in revenue.
Informational estimate only — not financial, tax, accounting, legal, or investment advice.

4 focused answers for this page
What is the break-even formula?
Break-even units equal fixed costs divided by contribution margin per unit. Contribution margin is price per unit minus variable cost per unit.
What if variable cost is higher than price?
The calculator shows an error because the unit does not contribute toward fixed costs when variable cost is equal to or greater than price.
Is this accounting advice?
No. This tool provides informational estimates only and is not financial, tax, accounting, legal, or investment advice.
Are my cost numbers uploaded?
No. Break-even calculations run locally in your browser and ClearUtils does not upload, store, fetch, or log entered numbers.
