Find out exactly how many units you need to sell to cover your costs. See contribution margin, margin of safety, and your profit or loss at any sales volume.
The break-even point is where total revenue equals total costs — neither profit nor loss. Every unit sold beyond that point generates pure profit. Understanding your break-even helps you set prices, plan marketing spend, decide whether to launch a product, and know when your business becomes sustainable. It's the first number any serious business owner must know.
The contribution margin (selling price minus variable cost per unit) is the key metric. A $50 product with $20 variable cost has a $30 contribution margin — meaning each sale contributes $30 toward covering fixed costs. Once enough units are sold to cover all fixed costs, those $30 become profit. Break-even units = Fixed Costs ÷ Contribution Margin. If your fixed costs are $9,000/month and your contribution margin is $30, you need to sell 300 units per month just to break even.
Fixed costs stay constant regardless of how much you produce or sell: rent, salaries, software subscriptions, insurance, loan payments. Variable costs scale with production: raw materials, per-unit packaging, shipping, payment processing fees, sales commissions. Getting this split right is critical — misclassifying a variable cost as fixed will understate your true break-even point and lead to pricing that loses money at scale.
Raising your price is the most powerful lever in break-even analysis because it increases contribution margin without adding cost. On a product with $15 variable cost and $6,000 in monthly fixed costs: at $40 price, you break even at 240 units. At $50, you break even at just 171 units — 29% fewer sales needed. But price increases must be tested against demand elasticity — a 25% price increase that costs you 30% of customers makes the math worse, not better.
