Break Even Calculator

Break even calculator: divide fixed costs by price minus variable cost. $10,000 fixed, a $25 price, and a $10 variable cost break even at 667 units ($16,675).

Break-Even Revenue$16,675.00

Formula Used

Break-even units = fixed costs / (price per unit - variable cost per unit), rounded up to a whole unit. Break-even revenue = units * price

How this calculator works

667 units is the break-even point when fixed costs are $10,000, the price is $25, and variable cost is $10. A break even calculator uses break-even units = fixed costs / (price per unit - variable cost per unit). The contribution margin is $25 - $10 = $15, and $10,000 / $15 = 666.67 units. The first whole unit that covers every fixed dollar is 667, and break-even revenue is 667 x $25 = $16,675. At 666 units the contribution is 666 x $15 = $9,990, which is $10 short.

For paid hours instead of unit sales, use the time card calculator, the timesheet calculator, or the punch clock calculator.

Formula

Worked example

Fixed costs are $10,000, variable cost is $10, and price is $25. Contribution margin is $25 - $10 = $15. Break-even units are $10,000 / $15 = 666.67, so the first whole unit that covers fixed costs is 667. Break-even revenue is 667 x $25 = $16,675. At 666 units the contribution is 666 x $15 = $9,990, which is $10 short.

Inputs

  • Total Fixed Costs ($)
  • Variable Cost per Unit ($)
  • Price per Unit ($)

Common mistakes

  • Dividing fixed costs by the selling price and ignoring variable cost, which understates the units you need.
  • Entering total variable costs for a period instead of variable cost per unit.
  • Stopping at 666 units when the exact result is 666.67. Those 666 units cover only $9,990 of $10,000 in fixed costs.
  • Treating break-even revenue as equal to fixed costs. Revenue also has to pay the variable cost of each unit sold.

Frequently asked questions

What is the break even calculator formula?

Break-even units = fixed costs / (price per unit - variable cost per unit). The denominator is the contribution margin. With $10,000 fixed, a $25 price, and a $10 variable cost, the margin is $15 and the exact break-even point is 666.67 units.

How many units do I need to break even?

Divide fixed costs by the contribution margin, then round up to a whole unit when you cannot sell a fraction. $10,000 / $15 = 666.67, so this break even calculator returns 667 units.

How do I calculate break-even revenue?

Multiply the whole units required by the price per unit. 667 x $25 = $16,675. That revenue covers $10,000 of fixed costs and $6,670 of variable costs (667 x $10), leaving $5 of profit.

What is contribution margin?

Contribution margin per unit is price minus variable cost. It is the amount each sale contributes toward fixed costs and then profit. At a $25 price and a $10 variable cost, the margin is $15.

What if price is not higher than variable cost?

There is no break-even point. Each sale loses money or only covers its own variable cost, so fixed costs are never recovered. The calculator shows N/A until price is above variable cost.

Does a break even calculator include payroll or lunch?

No. It covers unit sales, not work hours. For paid hours with an unpaid lunch, use the time card calculator, the timesheet calculator, or the punch clock calculator.
