How to Calculate Your Break-Even Point

Break-even analysis answers a simple but critical question: at what point does your revenue exactly cover all your costs? Below the break-even point, you are losing money. Above it, you are making profit.

This matters because many businesses look busy and active while still losing money. Revenue can be strong, but if costs are higher, the business is not yet viable. Break-even analysis gives you a concrete target to aim for instead of guessing.

To calculate break-even, you first need to separate your costs into two categories:

• Fixed costs stay the same regardless of how many units you sell. Examples include rent, insurance, software subscriptions, salaries, and loan payments. Whether you sell one unit or a thousand, these costs remain constant.
• Variable costs change in proportion to the number of units sold. Examples include raw materials, packaging, shipping per order, marketplace fees per sale, and sales commissions. The more you sell, the more you spend on variable costs.

Getting this separation right is important. If you misclassify a variable cost as fixed, your break-even calculation will be inaccurate and you may set your target too low.

Contribution margin is the amount of money each unit sale contributes toward covering your fixed costs and eventually generating profit. It is calculated as:

Contribution Margin = Selling Price per Unit - Variable Cost per Unit

For example, if you sell a product for $50 and the variable costs per unit are $20, your contribution margin is $30. Each sale puts $30 toward paying off your fixed costs. Once all fixed costs are covered, every additional $30 is profit.

You can also express contribution margin as a ratio by dividing it by the selling price. In this example, $30 / $50 = 0.60 or 60%. This ratio is useful when calculating break-even in revenue terms rather than units.

The standard break-even formula in units is:

Break-Even Point (units) = Fixed Costs / Contribution Margin per Unit

Using the example above, if your total fixed costs are $6,000 per month and your contribution margin is $30 per unit, your break-even point is 200 units per month. Sell fewer than 200, and you lose money. Sell more, and you profit.

To calculate break-even in revenue dollars instead:

Break-Even Point (revenue) = Fixed Costs / Contribution Margin Ratio

With $6,000 in fixed costs and a 60% margin ratio, break-even revenue is $10,000. This version is helpful when you sell multiple products at different prices and want a single revenue target.

Break-even analysis is not just about finding the zero-profit point. You can extend it to calculate how many units you need to sell to reach a specific profit goal. The adjusted formula is:

Units for Target Profit = (Fixed Costs + Target Profit) / Contribution Margin per Unit

If you want $3,000 in monthly profit with the same $6,000 fixed costs and $30 contribution margin, you need to sell ($6,000 + $3,000) / $30 = 300 units. This gives you a clearer operational target than just knowing where the break-even line is.

Use the break-even calculator to model different pricing, cost, and profit scenarios without doing the math by hand.
