Find out exactly how many units you need to sell — or how much revenue you need to earn — before your business starts making a profit. Adjust your costs and price, and see the break-even point update in real time.
Pro tip: Your contribution margin percentage is the single most important number here. A 60%+ margin means you break even quickly; below 30% means you need serious volume. Use the what-if slider to find the price point where margin and volume balance.

How to Use the Break-Even Calculator
Enter three numbers: your monthly fixed costs (rent, salaries, insurance — anything you pay whether you sell zero or a million), variable cost per unit (materials, shipping, packaging for each sale), and selling price per unit. The calculator instantly shows how many units you must sell each month to cover all your costs — your break-even point. Use the what-if slider to see how price changes affect that number.
What Is Break-Even Analysis?
Break-even analysis answers the most fundamental question in business: “How much do I need to sell before I stop losing money?” Below the break-even point, every unit sold still leaves you in the red. Above it, every additional unit generates pure profit (minus its variable cost). The formula is simple: divide fixed costs by the contribution margin per unit (selling price minus variable cost). But the strategic implications run deep — it tells you the minimum viable scale for your product, how risky a new venture is, and where pricing power matters most.
Understanding Contribution Margin
The contribution margin is the slice of each sale that goes toward covering fixed costs and, eventually, profit. If you sell a widget for $35 and it costs $12 to produce, your contribution margin is $23 per unit (65.7%). That $23 “contributes” to paying your $5,000 monthly rent, salaries, and overhead. Once you’ve sold enough widgets for those contributions to total $5,000, you’ve broken even. Higher margins mean fewer sales needed; lower margins demand higher volume.
How Price Changes Move the Break-Even Point
Small price adjustments can dramatically shift your break-even point. A 10% price increase on a $35 product adds $3.50 to your contribution margin — potentially reducing break-even volume by 13% or more. Conversely, discounting erodes margin fast: a 15% discount might require 25–40% more volume to compensate. The what-if slider lets you model these scenarios instantly, so you can find the sweet spot between competitive pricing and sustainable margins.
Fixed vs. Variable Costs in Practice
Getting the cost classification right is critical. Fixed costs stay constant regardless of output: office rent, salaried employees, insurance premiums, software subscriptions, loan payments. Variable costs scale with each unit: raw materials, shipping, payment processing fees, sales commissions, packaging. Some costs are semi-variable — like electricity that has a base charge plus usage — so split them proportionally. The more accurately you classify your costs, the more reliable your break-even number.
Multi-Product Break-Even Analysis
Most businesses sell more than one product. To find the blended break-even, you need to know each product’s price, variable cost, and its percentage of total sales (the “sales mix”). The weighted-average contribution margin combines each product’s margin proportionally, giving you a single break-even target in total units. Subscribers can model up to three products simultaneously and see how shifting the sales mix affects the overall break-even point.
Using Break-Even for Pricing Decisions
Break-even analysis is a powerful negotiation and planning tool. Before launching a product, calculate whether the required volume is realistic for your market size. Before offering a discount to a wholesale buyer, check how many more units you’d need to sell. Before signing a lease that doubles your rent, see how it shifts the break-even target. The profit projection table (available to subscribers) shows exact profit or loss at various sales volumes so you can pressure-test different scenarios before committing.

Frequently Asked Questions
What is a good contribution margin percentage?
Contribution margins above 60% are considered strong and allow a business to break even at relatively low volume. Margins between 30% and 60% are typical for product-based businesses. Below 30% usually means the business needs high volume or a pricing change to survive.
How do I calculate break-even in dollars instead of units?
Divide total fixed costs by the contribution margin ratio (contribution margin divided by selling price). If fixed costs are $10,000 and the contribution margin ratio is 40%, break-even revenue is $25,000.
Should I use gross or net fixed costs in a break-even analysis?
Use all fixed costs required to keep the business operating, including rent, salaries, insurance, software, loan payments, and depreciation. Excluding any ongoing obligation produces an artificially low break-even point.
How does raising prices affect break-even?
Price increases typically move break-even faster than cost cuts because the full increase flows directly into contribution margin. A 10% price increase on a product with a 40% margin reduces break-even volume by roughly 20%.
How often should a business recalculate its break-even point?
At minimum, recalculate quarterly and whenever fixed costs, prices, or variable costs shift materially. High-growth businesses and those with seasonal cost structures should model break-even monthly.
