How the Break-Even Point formula works

Break-even point in units:

Contribution margin = Price per unit − Variable cost per unit
Break-even units = Fixed costs / Contribution margin
Break-even revenue = Break-even units × Price per unit

Step-by-step calculation

  1. Subtract the variable cost per unit from the price per unit to find the contribution margin.
  2. Divide total fixed costs by the contribution margin to find the break-even unit count.
  3. Multiply the break-even unit count by the price per unit to find break-even revenue.

Worked example

Fixed costs of $10,000/month, selling at $50/unit with a variable cost of $30/unit: Contribution margin = $50 − $30 = $20. Break-even units = 10,000 / 20 = 500 units. Break-even revenue = 500 × $50 = $25,000.

Frequently asked questions

What counts as a fixed cost versus a variable cost?

Fixed costs stay the same regardless of sales volume, like rent or salaried wages. Variable costs scale with each unit sold, like raw materials or per-unit shipping. Getting this split right is essential for an accurate break-even point.

What happens after I pass the break-even point?

Every unit sold beyond break-even contributes its full contribution margin directly to profit, since fixed costs are already covered — which is why break-even analysis is often paired with profit-target planning.

Does break-even analysis account for taxes?

No — this is a pre-tax operational break-even point based on covering costs, not a target for after-tax net income. Tax planning is a separate calculation layered on top.
