Break-Even Calculator

Calculate how many units you must sell to cover your costs. Enter your fixed costs, selling price and variable cost per unit to see the break-even point, revenue and profit at a chosen sales level.

Enter your fixed costs, the selling price per unit and the variable cost per unit. The calculator finds the contribution margin per unit, the break-even units and revenue, and the profit or loss at the sales level you enter.

Contribution margin per unit
Break-even units
Break-even revenue
Profit / (loss) at {sales_units} units

A break-even calculator finds the sales volume at which total revenue exactly covers total costs — every unit sold beyond that point is profit. It's essential for pricing, launching products and setting sales targets.

The maths

  • Contribution margin = price − variable cost (what each unit contributes toward fixed costs)
  • Break-even units = fixed costs ÷ contribution margin
  • Break-even revenue = break-even units × price
  • Profit at a sales level = contribution margin × units − fixed costs

Examples

  • $10,000 fixed, $25 price, $10 cost = 667 units to break even
  • Break-even revenue = ~$16,667
  • At 1,000 units you make ~$5,000 profit

Frequently asked questions

What counts as a fixed cost?

Costs that don't change with output — rent, salaries, insurance, software subscriptions. Variable costs rise and fall with each unit made, like materials and packaging.

What if my price is below my variable cost?

Then each unit loses money and there's no break-even point — you'd never cover fixed costs. The result shows as a dash because the contribution margin is negative.

Just for the giggles, much love.
