Break-Even Calculator

Find your break-even point — how many units to sell or how much revenue to generate to cover all fixed and variable costs.

Quick Answer

A break-even calculator shows how many units must be sold, or how much revenue is needed, to cover fixed and variable costs.

Rent, salaries, insurance, etc.

Materials, labor per unit

Revenue per unit sold

Units needed to reach this profit

Break-Even Formulas

Break-Even Units = Fixed Costs / Contribution Margin per Unit Contribution Margin = Selling Price − Variable Cost per Unit Break-Even Revenue = Break-Even Units × Selling Price Units for Target Profit = (Fixed Costs + Target Profit) / Contribution Margin

Example: Small Business

Given

Fixed Costs

$10,000/mo

Variable Cost

$20/unit

Selling Price

$50/unit

Steps

  1. 1Contribution margin = $50 − $20 = $30 per unit
  2. 2Break-even units = $10,000 / $30 = 334 units
  3. 3Break-even revenue = 334 × $50 = $16,700

Result

Must sell 334 units or generate $16,700 in revenue to break even
