What is a Break-Even Point?
The break-even point is where your total revenue exactly equals your total costs — meaning your business is neither making a profit nor incurring a loss. Understanding this number helps you set realistic sales targets, evaluate pricing strategies, and make informed decisions about expanding your product line.
The Break-Even Formula
The break-even formula in units is Break-Even = Fixed Costs / (Price per Unit - Variable Cost per Unit). The denominator — price minus variable cost — is called the contribution margin. Each unit sold contributes this amount toward covering your fixed costs. Once you have sold enough units to cover all fixed costs, every additional sale becomes profit.
Fixed Costs vs Variable Costs
Fixed costs remain the same regardless of how many units you sell — rent, salaries, insurance, and equipment leases are common examples. Variable costs change in direct proportion to production volume: raw materials, packaging, shipping, and payment processing fees are typical variable costs. Correctly categorizing your costs is essential for an accurate break-even analysis.
- Fixed Costs — Rent, salaries, insurance, software subscriptions, and loan payments that stay constant month to month.
- Variable Costs — Raw materials, packaging, shipping, commissions, and transaction fees that scale with each unit sold.

Contact SupportThe break-even point is the number of units sold or the revenue amount at which total costs equal total revenue, resulting in zero profit and zero loss. Below the break-even point the business operates at a loss. Above it, every additional unit sold contributes directly to profit.
The break-even point in units is: Fixed Costs / (Selling Price per Unit - Variable Cost per Unit). The break-even point in revenue is: Fixed Costs / Contribution Margin Ratio. The denominator (Selling Price minus Variable Cost) is called the contribution margin per unit.
Fixed costs remain the same regardless of how many units you produce or sell, such as rent, salaries, and insurance. Variable costs change in proportion to production or sales volume, such as raw materials, packaging, and shipping per unit. Correctly classifying costs is essential for accurate break-even analysis.
Calculate your break-even point at different price levels to see how many units you need to sell at each price to cover costs. Higher prices mean fewer units needed to break even but may reduce demand. Lower prices require more volume but may increase market share. Use break-even analysis alongside market research to find the optimal price.
Contribution margin is the selling price per unit minus the variable cost per unit. It represents the amount each unit sold contributes toward covering fixed costs and generating profit. The contribution margin ratio is the contribution margin divided by the selling price, expressed as a percentage.
Break-even analysis helps you determine the minimum sales volume needed before a product or business becomes profitable. It informs decisions about pricing, cost control, and sales targets. Investors and lenders also use break-even analysis to assess the viability and risk level of a business plan.
Yes, the break-even point changes whenever fixed costs, variable costs, or selling prices change. Rent increases, supplier price changes, new hires, or price adjustments all shift the break-even point. Recalculate your break-even point regularly and whenever you make significant changes to your cost structure or pricing.
A break-even chart is a graph that plots total revenue and total costs against the number of units sold. The point where the two lines intersect is the break-even point. The area below the intersection represents losses and the area above represents profit. It provides a visual way to understand how volume affects profitability.
