DocomintBreak-Even Point Calculator
Calculate how many units you need to sell to cover fixed and variable costs.
Break-even analysis answers the first question any new product or business needs answered: how many units have to sell before fixed costs (rent, salaries, equipment — costs that don't change with volume) are covered by the profit margin on each unit sold.
Example: A product with $12,000 in fixed costs, sold at $40/unit with $15/unit in variable costs, needs to sell 480 units to break even ($12,000 ÷ $25 contribution margin per unit) — the 481st unit onward is where actual profit starts.
How it works
- Enter fixed costs, price per unit, and variable cost per unit
- Press Calculate
- The break-even unit count and revenue appear instantly, calculated on your device
Frequently asked questions
What counts as a fixed cost vs. a variable cost?
Fixed costs (rent, salaries, insurance) stay the same regardless of how many units you sell. Variable costs (materials, packaging, per-unit shipping) scale directly with each unit produced or sold.
What happens if the price is lower than the variable cost per unit?
You lose money on every unit sold, before fixed costs are even considered — there's no volume of sales that reaches break-even, since each additional sale makes the loss worse, not better. This calculator flags that case as an error rather than returning a nonsense negative break-even point.
