Break-Even Calculator
Find the break-even point for a business or product — how many units you need to sell to cover costs. Includes contribution margin and target profit analysis.
What Is the Break-Even Point and Why Does It Matter?
The break-even point is the level of sales at which total revenue equals total costs — meaning there is no profit and no loss[reference:0]. It's the point where a business starts to become profitable. Understanding your break-even point is essential for pricing, budgeting, and financial planning.
The Break-Even Formula
The formula for break-even analysis is: Break-Even Units = Fixed Costs ÷ (Selling Price per Unit – Variable Cost per Unit)[reference:1][reference:2]. The denominator — selling price minus variable cost — is called the contribution margin per unit[reference:3].
Fixed Costs vs. Variable Costs
Fixed costs are expenses that do not change with the level of production — such as rent, salaries, insurance, and equipment leases[reference:4]. Variable costs change directly with production — such as raw materials, packaging, and shipping. The more units you produce, the higher your total variable costs.
The Contribution Margin
The contribution margin is the difference between the selling price per unit and the variable cost per unit[reference:5]. It represents how much each unit sold contributes to covering fixed costs and generating profit. The higher your contribution margin, the fewer units you need to sell to break even.
Using Break-Even Analysis for Business Decisions
Break-even analysis helps you make smarter business decisions: pricing (can you raise prices?), cost control (can you reduce variable costs?), investment decisions (will a new product be profitable?), and sales targets (how many units do you need to sell?). It's a fundamental tool for any business owner or manager.

The contribution margin is the difference between the selling price per unit and the variable cost per unit. It represents how much each unit sold contributes to covering fixed costs and generating profit.
Fixed costs are expenses that do not change with the level of production or sales — such as rent, salaries, insurance, and equipment leases. They must be paid regardless of how much you sell.
Variable costs are expenses that change directly with the level of production — such as raw materials, packaging, and shipping. The more units you produce, the higher your total variable costs.
