Break-Even Point

Your break-even point is the level of sales at which your business covers all of its costs — both fixed and variable — with zero profit and zero loss. It's the line between red and black, and every business owner should know exactly where it is.

To calculate it, you need three numbers: your fixed costs (rent, insurance, salaries, loan payments — expenses that don't change with sales volume), your variable costs per unit (materials, shipping, commissions — expenses that increase with each sale), and your price per unit. The formula is: Break-Even Units = Fixed Costs ÷ (Price per Unit - Variable Cost per Unit). The difference between price and variable cost is your contribution margin — the amount each sale contributes toward covering fixed costs.

You can also express the break-even point in dollars: Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio (where the ratio is contribution margin ÷ price). This is more useful for service businesses or businesses with many products at different price points. Knowing your break-even point helps you set sales targets, evaluate pricing changes, and understand how much room you have before you start losing money.

Your break-even point is the minimum your business needs to survive. Below it, you're burning cash. Above it, you're profitable. This number should inform every major decision: Can you afford to hire another employee? How much does that raise your break-even point? If you lower prices by 10%, how many more units do you need to sell to still break even? What happens to your break-even point if rent increases? Understanding break-even analysis prevents you from making decisions that feel right but are financially unsustainable.
