Break-Even Analysis Guide
Our free break-even calculator helps businesses, startups, retailers, e-commerce sellers, freelancers and service providers estimate the sales volume needed to cover fixed and variable costs.
You can calculate break-even units, break-even sales revenue, contribution margin, sales needed for a target profit and margin of safety.
The break-even point is the level of sales at which total revenue equals total costs. At this point, the business has covered the costs included in the analysis but has not generated a profit above them.
Break-even analysis can help with pricing decisions, sales targets, cost planning and evaluating how changes in price or variable cost may affect the sales volume required to cover fixed costs.
First subtract variable cost per unit from selling price per unit. The result is contribution margin per unit. Then divide total fixed costs by that contribution margin.
Break-Even Units = Fixed Costs ÷ (Selling Price − Variable Cost)
For example, suppose fixed costs are 10,000, selling price per unit is 50 and variable cost per unit is 30. Contribution margin per unit is 20, so the calculated break-even point is 500 units.
Contribution margin per unit is the difference between selling price per unit and variable cost per unit. Under a basic break-even model, this amount contributes toward covering fixed costs.
Contribution Margin per Unit = Selling Price − Variable Cost
| Cost Type | Description | Common Examples |
|---|---|---|
| Fixed Costs | Costs treated as unchanged within the assumed activity range | Rent, certain salaries, insurance, subscriptions |
| Variable Costs | Costs that vary with units produced or sold | Materials, unit packaging, transaction-related costs |
If you know the contribution margin ratio, divide fixed costs by the contribution margin ratio expressed as a decimal.
Break-Even Sales = Fixed Costs ÷ Contribution Margin Ratio
Break-even analysis can be extended to estimate the number of units needed for a desired target profit. Add target profit to fixed costs and divide by contribution margin per unit.
Required Units = (Fixed Costs + Target Profit) ÷ Contribution Margin per Unit
Margin of safety compares actual or projected sales with break-even sales. A positive value indicates sales are above the break-even level, while a negative value indicates sales are below it.
Margin of Safety = Actual Sales − Break-Even Sales
A break-even calculator may be useful for startups, retailers, e-commerce stores, manufacturers, restaurants, freelancers, agencies and service businesses that want to estimate the sales volume needed to cover included costs.
A simple break-even calculation assumes the entered values reasonably represent the relevant business conditions. In practice, selling prices, variable costs, fixed costs, product mix, discounts, taxes and sales volume may change.
Results should therefore be treated as estimates based on the inputs and assumptions used rather than guaranteed future business outcomes.
