  3. Optionally enter a target profit to see how many units that takes.
  4. Click Calculate to see your break-even point.
Example: $10,000 fixed costs, $50 price, $30 variable cost = $20 contribution per unit. Break-even = 500 units, or $25,000 in sales.

Frequently asked questions

What is the break-even point?

The point where total revenue equals total costs — you are neither making nor losing money. Sell one unit beyond it and you start profiting.

How do you calculate break-even units?

Divide fixed costs by the contribution margin per unit (selling price minus variable cost per unit). For example, $10,000 fixed costs and a $20 contribution margin means 500 units to break even.

What counts as a fixed cost?

Costs that do not change with sales volume: rent, salaries, insurance, and software subscriptions. Variable costs change with each unit, like materials and packaging.
