How to Calculate the Break-Even Point
Break-even analysis tells you exactly how many units you need to sell to cover all your costs — the point where revenue equals total expenses.
- Fixed costs — expenses that stay the same (rent, salaries, insurance)
- Variable cost — cost per unit (materials, shipping, packaging)
- Contribution margin = Selling Price − Variable Cost per unit
- Break-even revenue = Break-even units × Selling price
Example: $10,000 fixed costs, $10 variable cost, $25 price → $10,000 ÷ $15 = 667 units ($16,675 revenue)
Tips & Considerations
- Double-check your fixed costs before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both break-even units and break-even revenue — they work together to give you the full picture.

Frequently Asked Questions
What is a break-even point?
The break-even point is the number of units you must sell for total revenue to equal total costs, resulting in zero profit and zero loss. Every unit sold beyond the break-even point generates profit. Below this point, the business operates at a loss.
How do you calculate the break-even point?
Break-Even Units = Fixed Costs / (Selling Price per Unit − Variable Cost per Unit). The denominator is the contribution margin per unit. For example, with $10,000 fixed costs, $25 price, and $10 variable cost: 10,000 / (25 − 10) = 667 units.
What is contribution margin?
Contribution margin is the selling price minus the variable cost per unit. It represents how much each unit contributes toward covering fixed costs and generating profit. A higher contribution margin means fewer units are needed to break even.
What are fixed costs vs variable costs?
Fixed costs remain the same regardless of output — rent, salaries, insurance, and loan payments. Variable costs change with each unit produced — raw materials, packaging, shipping, and sales commissions. Accurately categorizing these is essential for break-even analysis.
How can I lower my break-even point?
Three strategies: reduce fixed costs (renegotiate rent, reduce overhead), lower variable costs per unit (cheaper materials, better efficiency), or increase your selling price. Each has tradeoffs — raising prices can reduce demand, while cutting costs may affect quality.
Why is break-even analysis important?
Break-even analysis helps you set realistic sales targets, price products correctly, evaluate new business ideas, decide whether to launch a product, and understand how cost or price changes affect profitability. It is fundamental to business planning and investment decisions.
