Contribution margin
Selling price − Variable cost
$50 − $20 = $30Plan with a clear floor
Find how many units you need to sell before your revenue covers fixed and variable costs. Then see what your planned sales volume could earn.

Contribution margin / unit

A quick read
Break-even analysis connects your fixed costs with the contribution created by each sale. It helps you set a practical sales target instead of guessing how much volume you need.
Include rent, salaries, software, insurance, or other period costs.
Enter the variable cost and selling price for a single unit.
Review the break-even volume and projected result at your planned sales.
The math
Selling price − Variable cost
$50 − $20 = $30Fixed costs ÷ Contribution margin
$2,000 ÷ $30 = 66.67Contribution × Units − Fixed costs
$30 × 100 − $2,000 = $1,000Important: break-even is only available when selling price is higher than variable cost. If the contribution margin is zero or negative, each additional sale cannot cover fixed costs.
Worked example
With a $20 variable cost and a $50 selling price, each sale contributes $30. You need 66.67 units, or 67 whole units, to move above break-even.
Questions, answered
The break-even point is the number of units or amount of revenue needed for total revenue to cover fixed and variable costs. Profit is zero at the exact point.
There is no contribution margin, so sales cannot help cover fixed costs. The calculator will show that break-even is unavailable.
Use the exact decimal for analysis, then round up to the next whole unit when setting a real sales target. You cannot sell a fraction of a unit in many businesses.
Contribution margin per unit is selling price minus variable cost per unit. It is the amount each sale contributes toward fixed costs and profit.
