What is Break-Even Calculator?
A break-even calculator determines the point at which your total revenue equals your total costs, meaning you're neither making nor losing money. This is one of the most fundamental calculations in business planning, helping you understand how many units you need to sell or how much revenue you need to generate to cover all your expenses.
The break-even point is crucial for startup planning, new product launches, and financial forecasting. It tells you the minimum performance required to avoid losses and serves as a baseline for setting sales targets. Everything sold beyond the break-even point contributes directly to profit, making it a key metric for understanding your business's financial health.
When to Use This Calculator
- Deciding on a price point for a new product before launch
- Figuring out how many units you need to sell monthly to cover fixed costs
- Evaluating whether a proposed price cut still lets you break even at expected volume
- Comparing break-even points across different cost structures (e.g., in-house vs outsourced production)
- Setting a sales target for a new hire or campaign tied directly to profitability
- Checking how a rise in variable costs (materials, shipping) shifts your break-even volume
Steps:
- Enter your total fixed costs (rent, salaries, etc.).
- Enter the selling price per unit.
- Enter the variable cost per unit (materials, labor per unit).
- View the break-even point in units and revenue.
- Analyze how changes in price or costs affect your break-even point.
Formula
Break-Even Units = Fixed Costs / (Selling Price - Variable Cost per Unit)
Break-Even Revenue = Fixed Costs / Contribution Margin Ratio
Contribution Margin = Selling Price - Variable Cost
Contribution Margin Ratio = Contribution Margin / Selling Price
Profit = (Units × Contribution Margin) - Fixed Costs
Use Cases
- Planning a new business or product launch
- Setting sales targets and performance goals
- Evaluating the financial viability of a business idea
- Analyzing the impact of price changes on profitability

- Profit Calculator: Once you're selling above break-even, our profit calculator shows exactly how much net profit — after cost of goods, operating expenses, and tax — each additional unit of sales actually contributes.
- Profit Margin: Contribution margin (used to find break-even) and overall profit margin (used to judge total business health) are related but different — check your broader margin picture with our profit margin calculator.
- Margin Calculator: If you're setting a price and want to work from a target margin percentage rather than a target break-even volume, our margin calculator approaches the same pricing problem from the other direction.
- ROI: For a one-time product launch or campaign, comparing your investment against expected returns is a related but distinct question from break-even — our general ROI calculator handles that comparison.
- Cash Flow Forecasting: Break-even tells you the volume needed to be profitable on paper, but cash flow timing (when money actually arrives) is a separate concern — project it with our cash flow forecast calculator.
Example
A bakery has fixed costs of $5,000/month. Each cake sells for $30 and costs $12 to make. Contribution margin = $30 - $12 = $18 per cake. Break-even = $5,000 / $18 = 278 cakes per month. That's about 9-10 cakes per day. Every cake sold beyond 278 generates $18 in profit.
Interpreting Your Results
Break-even units is the point where total revenue exactly equals total costs — sell fewer units than this and you lose money, sell more and every additional unit contributes pure profit equal to your contribution margin (price minus variable cost per unit). A low break-even point relative to your realistic sales volume means more margin for error; a break-even point close to or above what you can realistically sell signals the price, cost structure, or fixed overhead needs to change before the product is viable. Contribution margin — not the break-even number itself — is usually the more actionable lever: raising price or cutting variable cost per unit lowers your break-even point faster than trying to cut fixed costs, which are often harder to reduce quickly. Always run this with a conservative volume estimate, not your best-case forecast — the gap between your break-even point and your realistic (not optimistic) sales volume is your actual margin of safety.
