Break-even calculator
See how many sales cover your fixed costs, then set a target profit and test a higher or lower selling price. Results update as you change the inputs.
- Sales and target profit

Enter your costs and price
All amounts use the same sales period.
Costs you pay regardless of sales.
The amount a customer pays for one unit.
The cost incurred for each unit sold.
Optional profit goal beyond break-even.
Your break-even point
Whole units are rounded up so the target is actually reached.
Sales needed to break even
67 units
$1,675 in sales revenue · $15 contribution per unit
- Units for target profit
- 100
- Revenue at target
- $2,500
Actual profit at 100 whole sales: $500.
Profit by sales volume
Profit = units × contribution per unit − fixed costs
What if the selling price changes?
Scenarios change the price by 10% and round it to the nearest cent; other inputs stay fixed.
Transparent math
Break-even formula and example
Contribution per unit = selling price − variable cost. Break-even units = fixed costs ÷ contribution per unit, rounded up to the next whole sale. To reach a profit target, divide fixed costs plus target profit by contribution per unit. Revenue is units × selling price.
Example: $1,000 fixed costs, a $25 selling price and $10 variable cost leave $15 per sale. You need 67 sales to cover fixed costs, bringing in $1,675 in revenue. To earn at least $500 profit, you need 100 sales. If the selling price is at or below variable cost, sales cannot cover fixed costs under this model.
What this model includes
- Fixed costs for one period
- One selling price and variable cost per unit
- Target profit beyond break-even
- Whole-unit rounding and ±10% price scenarios
Use the estimate responsibly
Model limits
Keep all inputs in the same period and currency. The model assumes one product, constant price and variable cost, and whole units sold. It excludes taxes, refunds, changing costs, inventory constraints and demand. A lower price may increase demand, but this calculator does not forecast it.
