Break-even Calculator
Calculate how many units you need to sell to cover fixed and variable costs.
Enter values and press Calculate.
How this calculator works
Break-even units equal fixed costs divided by contribution margin per unit, where contribution margin is selling price minus variable cost.
How to use the result
Change one input at a time to compare scenarios. This helps you see which factor has the biggest effect on your total cost or savings.
Results are estimates for planning and comparison. Actual costs can differ because of taxes, tariffs, fees, usage patterns, equipment efficiency and local conditions.
Frequently asked questions
What are fixed costs?
Costs that do not change directly with each unit sold, such as rent or salaried overhead.
What are variable costs?
Costs that rise with each unit sold, such as materials, packaging or transaction fees.
What if variable cost is higher than selling price?
There is no positive contribution margin, so increasing unit sales will not produce a break-even point.
