About the Break-Even Calculator

This Break-Even Calculator helps businesses and entrepreneurs determine the exact number of units they must sell — or the revenue they must generate — to cover all their costs and reach profitability. It calculates break-even units, break-even revenue, contribution margin, and contribution margin ratio, with an interactive chart and scenario analysis.

Break-Even Formulas

Break-Even Units = Fixed Costs ÷ Contribution Margin per Unit

Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio

Contribution Margin = Selling Price − Variable Cost per Unit

Contribution Margin Ratio = Contribution Margin ÷ Selling Price × 100%

Units for Target Profit = (Fixed Costs + Target Profit) ÷ Contribution Margin

How to Use the Break-Even Calculator

1. Enter Total Fixed Costs — All costs that don't vary with sales: rent, salaries, insurance, depreciation, loan payments.
2. Enter Selling Price per Unit — The price at which you sell each product or service.
3. Enter Variable Cost per Unit — Costs that scale with production: raw materials, direct labor, packaging, commissions, shipping.
4. Optional: Enter Target Profit — If you want to know how many units you need to sell to achieve a specific profit, enter that amount here.
5. Click Calculate — Get your break-even point, contribution margin, interactive chart, and scenario analysis instantly.

Understanding the Break-Even Chart

The break-even chart shows three lines: Revenue (green), Total Cost (red), and Fixed Cost (gray dashed). The point where the Revenue and Total Cost lines intersect is the break-even point. To the left of this intersection is the Loss Zone — where costs exceed revenue. To the right is the Profit Zone — where revenue exceeds costs.

What is Contribution Margin Ratio?

The Contribution Margin Ratio (CM Ratio) expresses contribution margin as a percentage of selling price. A CM Ratio of 40% means 40 cents of every dollar in revenue goes toward covering fixed costs and profit. Once fixed costs are covered, that 40 cents becomes profit. Higher CM Ratios allow businesses to reach profitability faster and with lower sales volume.

Frequently Asked Questions

What is a break-even point?

The break-even point is the level of sales at which total revenue equals total costs, resulting in zero profit or loss. It represents the minimum sales volume required to avoid a loss.

What is contribution margin?

Contribution margin is the difference between selling price and variable cost per unit. It represents the amount each unit sold contributes toward covering fixed costs. Once fixed costs are fully covered, contribution margin becomes profit.

What is a good contribution margin ratio?

CM Ratio benchmarks vary widely by industry: Software/SaaS businesses typically achieve 60–90%, professional services 50–70%, retail 20–40%, restaurants 10–25%, and manufacturing 20–50%. Higher ratios indicate greater pricing power and more efficient scalability.

How do I lower my break-even point?

You can reduce your break-even point by: (1) reducing fixed costs (renegotiate rent, reduce headcount), (2) reducing variable costs (negotiate supplier prices, improve efficiency), (3) increasing selling price (premium positioning, bundling), or (4) changing your product/service mix toward higher-margin items.

What happens to profit after the break-even point?

Once you exceed the break-even point, every additional unit sold generates profit equal to the contribution margin per unit. Since all fixed costs are already covered, there are no more overhead costs to absorb — pure margin flows to the bottom line.

Can I use this calculator for a service business?

Yes. For service businesses, "units" can represent billable hours, client projects, service packages, or subscriptions. Fixed costs include overhead like office space and salaries; variable costs include direct service delivery costs like contractor fees or materials.
