The break-even point is where total revenue equals total cost, so profit is zero. Contribution margin is selling price minus variable cost per unit — the amount each sale contributes toward fixed costs. This calculator assumes a single product with constant price and costs; for multiple products, calculate a weighted-average contribution margin. Results are estimates for planning purposes.
What Is the Break-Even Point?
The break-even point is the level of sales at which total revenue exactly equals total cost, so the business makes neither a profit nor a loss. At this point, every cost has been covered, but nothing has yet been earned. Sell one unit beyond the break-even point and you begin to make a profit; sell one unit below it and you make a loss.
Knowing your break-even point is one of the most important calculations in business. It tells you the minimum you must sell to survive, helps you set prices with confidence, and shows you how much room you have before losses begin. For anyone starting a business, launching a product, or preparing a business plan, break-even analysis is essential.
The Break-Even Formulas
There are two ways to express the break-even point, and this calculator shows both.
The break-even point in units is calculated as fixed costs divided by the contribution margin per unit. The contribution margin per unit is simply the selling price per unit minus the variable cost per unit. For example, with fixed costs of 50,000, a selling price of 25, and a variable cost of 15, the contribution margin is 10 per unit, so the break-even point is 50,000 divided by 10, which equals 5,000 units.
The break-even point in revenue is calculated as fixed costs divided by the contribution margin ratio. The contribution margin ratio is the contribution margin per unit divided by the selling price, expressed as a percentage. In the same example, the ratio is 40%, so the break-even revenue is 50,000 divided by 0.40, which equals 125,000. You can also reach this by multiplying the break-even units by the selling price.
Understanding Contribution Margin
The contribution margin is the heart of break-even analysis. It is the amount each unit sold contributes toward covering fixed costs, and once those are covered, toward profit. It is calculated as selling price minus variable cost per unit.
The contribution margin ratio expresses this as a percentage of the selling price. A higher contribution margin means each sale does more work, so you need to sell fewer units to break even. Improving your contribution margin, by raising your price or lowering your variable cost, is one of the most effective ways to reduce your break-even point and increase profitability.
Fixed Costs vs Variable Costs
Break-even analysis depends on correctly separating your costs into two types.
Fixed costs are expenses that do not change with the level of production or sales. They remain the same whether you sell one unit or one thousand. Common examples include rent, salaries, insurance, and equipment leases.
Variable costs are expenses that change directly with the number of units produced or sold. The more you produce, the higher they are. Common examples include raw materials, direct labour, packaging, and sales commissions.
Some costs are mixed, containing both a fixed and a variable element, such as a utility bill with a standing charge plus usage. For accurate break-even analysis, these should be separated into their fixed and variable parts.
What Is the Margin of Safety?
The margin of safety tells you how far your expected or actual sales are above the break-even point. It is the cushion you have before you start making a loss. It can be expressed in units, in revenue, or as a percentage.
The margin of safety as a percentage is calculated as expected sales minus break-even sales, divided by expected sales. For example, if you expect to sell 8,000 units and your break-even point is 5,000 units, your margin of safety is 3,000 units, or 37.5%. This means sales could fall by up to 37.5% before you reach break-even. A higher margin of safety means lower risk.
Target Profit Analysis
Break-even analysis can be extended to work out how many units you need to sell to reach a specific profit target, not just to break even. The formula is fixed costs plus target profit, divided by the contribution margin per unit.
For example, with fixed costs of 50,000, a target profit of 20,000, and a contribution margin of 10 per unit, you would need to sell 70,000 divided by 10, which equals 7,000 units. This makes break-even analysis a powerful planning tool for setting realistic sales goals.
How to Lower Your Break-Even Point
If your break-even point is higher than you would like, there are three main levers you can pull. You can increase your selling price, which raises the contribution margin on every unit, though you must consider whether the market will bear it. You can reduce your variable cost per unit, for example by negotiating better rates with suppliers or improving production efficiency. Or you can reduce your fixed costs, such as moving to cheaper premises or cutting overhead. The cost-volume-profit chart on this page lets you see the effect of each of these changes instantly.
Frequently Asked Questions (FAQS)
Divide your total fixed costs by your contribution margin per unit, which is the selling price minus the variable cost per unit. The result is the number of units you need to sell to break even. To find the break-even point in revenue, multiply that figure by your selling price, or divide fixed costs by the contribution margin ratio.
The contribution margin is the selling price of a unit minus its variable cost. It is the amount each sale contributes toward covering fixed costs, and after those are covered, toward profit. It can be expressed per unit or as a ratio (percentage) of the selling price.
Fixed costs stay the same regardless of how much you produce or sell, such as rent and salaries. Variable costs change directly with production volume, such as raw materials and sales commissions. Correctly separating the two is essential for accurate break-even analysis.
There is no single ideal figure, as it varies by industry and risk appetite. Generally, the higher the margin of safety, the lower the risk, because sales can fall further before reaching break-even. A low margin of safety means the business is operating close to its break-even point and is more vulnerable to a drop in sales.
Yes. Although the classic formula uses units, service businesses can apply it using billable hours, projects, or clients as the unit, or by working in revenue terms using the contribution margin ratio. The principle of covering fixed costs before earning profit applies to any business.
If your selling price is equal to or below your variable cost, each sale loses money or contributes nothing toward fixed costs. In that situation there is no break-even point, because selling more units increases your losses rather than moving you toward profit. The contribution margin must be positive for break-even analysis to work.
A cost-volume-profit chart is a graph that plots total revenue and total cost against the number of units sold. The point where the two lines cross is the break-even point. The area where revenue is above cost is the profit zone, and the area where cost is above revenue is the loss zone. It is a clear visual way to understand how sales volume affects profit.
