Break-Even Calculator

The break-even point is the level of sales at which total revenue equals total costs (fixed + variable), resulting in zero profit or loss. It tells you the minimum number of units you must sell (or hours you must bill) to cover all your costs. Any sales beyond this point generate profit.

For product businesses: Break-even units = Fixed costs / (Selling price - Variable cost per unit). The denominator is called the contribution margin. For service businesses: Break-even hours = Monthly overheads / (Hourly rate - Variable cost per hour). If there are no variable costs per hour, it simplifies to overheads divided by hourly rate.

Fixed costs are expenses that remain the same regardless of how many units you sell. Common examples include: rent, insurance, salaries (for non-production staff), loan payments, software subscriptions, and accounting fees. These costs must be paid even if you sell nothing. Understanding your fixed costs is essential for accurate break-even analysis.

Variable costs change in proportion to sales volume. Examples include: raw materials, packaging, shipping, sales commissions, payment processing fees, and direct labour for production. The variable cost per unit should include everything that increases with each additional sale. Accurately tracking variable costs is crucial for pricing and profitability.

Contribution margin is the difference between the selling price and the variable cost per unit. It represents how much each sale contributes towards covering fixed costs and generating profit. A higher contribution margin means you reach break-even faster. Contribution margin percentage = (Selling price - Variable cost) / Selling price x 100.

You can lower break-even by: (1) reducing fixed costs (negotiate rent, cut unnecessary subscriptions), (2) reducing variable costs per unit (bulk purchasing, more efficient processes), (3) increasing your selling price (if the market allows), or (4) changing your product mix to favour higher-margin items. Most businesses use a combination of these approaches.

Break-even analysis shows the minimum price you must charge to cover costs at a given sales volume. If your break-even point requires selling more units than the market can support, you need to raise prices or cut costs. It also helps you evaluate the impact of discounts — a 10% discount might increase the break-even volume by far more than 10%.

Product businesses have clear per-unit variable costs (materials, shipping) and calculate break-even in units sold. Service businesses often have minimal variable costs per hour and higher fixed costs (salaries), so break-even is calculated in billable hours or revenue. The concept is identical but the inputs differ.

Yes, if you want an accurate picture. Include your desired salary (or minimum living expenses) as a fixed cost. Many new businesses make the mistake of excluding the founder's salary, which makes break-even look artificially low. A business that covers all costs except your income is not truly viable long-term.

Recalculate whenever your costs or prices change significantly — at minimum quarterly. Key triggers include: rent reviews, price changes (yours or suppliers), new hires, changes in sales volume, or entering new markets. Many businesses build break-even into their monthly management accounts to track how actual performance compares to the break-even threshold.
