Break-Even Calculator
Use this break-even calculator to estimate how many units or how much revenue may be needed before contribution margin covers fixed costs. It can help test pricing, cost, and sales-volume assumptions, but it is a planning model rather than a demand forecast or a guarantee that sales will reach the break-even point.
How to use this calculator
- Enter fixed costs for the period you want to analyze, such as a month or year.
- Enter price per unit and variable cost per unit using the same unit definition.
- Use break-even units and revenue as a planning estimate, then compare it with realistic demand and capacity assumptions.
Formula
- Contribution margin per unit = price per unit - variable cost per unit
- Break-even units = fixed costs / contribution margin per unit
- Break-even revenue = break-even units x price per unit
Example calculation
With $25,000 in fixed costs, a $75 unit price, and $30 variable cost per unit, contribution margin is $45. Break-even volume is about 556 units and break-even revenue is about $41,700.
How to interpret the results
- Read break-even units as the estimated sales volume needed to cover the modeled fixed and variable costs, not as a profit target.
- Compare the break-even volume with realistic demand, production capacity, sales capacity, and time period assumptions.
- If contribution margin is low or negative, review pricing, variable costs, and product economics before relying on the result.
Frequently asked questions
What if variable cost is higher than price?
Then each sale loses money before fixed costs. The calculator will flag that break-even cannot be reached with those inputs.
Does break-even mean the business is profitable?
Break-even means estimated revenue covers the modeled fixed and variable costs. It does not include every possible expense or cash flow timing issue.
Should fixed costs be monthly or annual?
Use a consistent period. If fixed costs are monthly, the break-even output is for that month. If fixed costs are annual, the output is annual.
