What to enter
| Input | Meaning and units |
|---|---|

| Variable cost per unit | Enter variable cost per unit using the definition in the method and example. |
Understanding your result
The outputs describe the mathematical scenario you entered. Assumed rates, timing and included costs determine the result; an estimate is not an offer or eligibility decision.
Common mistakes
- Mixing annual and monthly periods, or leaving out a cost that the model does not include.
Check your calculation
- Compare a simple one-period or zero-change case with hand arithmetic before applying a longer scenario.

How many units must I sell to cover my costs?
Enter fixed costs, selling price and variable cost per unit to estimate the minimum whole-unit sales needed to cover those costs.
Common uses
- Estimate the sales quantity needed to cover a fixed expense.
- Compare break-even quantities under different prices or costs.
How it works
Contribution per unit is selling price minus variable cost. Divide fixed costs by that contribution and round the required unit count upward. Price must exceed variable cost. The result assumes all units sell at the same price and costs remain constant over the period.
Worked example
Fixed costs 1,000, price 25 and variable cost 10 give contribution 15. The minimum is ceil(1,000 ÷ 15) = 67 units.
