Break-Even Point Calculator

The break-even point is the sales volume at which total revenue exactly equals total costs, so a business stops losing money and starts covering its own operating expenses. Founders use this calculation before launch, before a pricing change, or before signing a lease, because it converts abstract fixed costs and variable costs into one concrete number: how many units, or how many dollars of revenue, must move before the business is self-sustaining.

Getting the break-even point wrong has real consequences. Underestimate fixed costs or overestimate the price customers will pay, and a founder can run out of cash months before the business was ever supposed to turn a profit. This calculator is for anyone pricing a product, opening a location, or deciding whether a new line is worth launching, and it answers a single practical question: at what volume does this venture pay for itself?

How it's calculated

The calculation starts with contribution margin: subtract the variable cost per unit from the selling price per unit. That figure is how much of each sale is left over, after direct costs, to pay down the fixed costs of the business, such as rent, salaries and insurance. Divide total fixed costs by the contribution margin per unit and the result is the break-even point in units, the exact quantity that must be sold before the business earns its first dollar of profit. Multiply that unit figure by the selling price to get break-even revenue, the sales total that corresponds to the same point.

Three inputs drive the whole calculation, and each one is easy to get wrong. Fixed costs should include everything that does not change with sales volume, not just rent, but also base salaries, software subscriptions and insurance; leaving out a recurring cost is the most common mistake, similar to the allocation errors covered in how absorption costing allocates overhead. Variable cost per unit should include every cost that scales directly with each sale, including materials, packaging, payment-processing fees and sales commissions, the same components that determine how sales mix affects blended profitability. If the selling price is lower than the variable cost, the contribution margin is negative and there is no break-even point at any volume.

Worked examples

Small service business

A local coffee shop has fixed costs of $8,000 a month covering rent, wages and utilities. Each cup sells for $5 and costs $1.50 in beans, milk and cups, a contribution margin of $3.50. Dividing $8,000 by $3.50 gives a break-even point of 2,286 cups a month, or roughly 76 cups a day. At $5 each, that is $11,430 in break-even revenue. Coffee-focused retail is a useful comparison here, since the fixed-cost structure resembles what shows up in the market analysis of large coffee chains, just at a much smaller scale.

Higher fixed-cost venue

An entertainment venue with expensive equipment, like the setups examined in VR gaming arena economics, might carry $60,000 in monthly fixed costs against a $40 session price and $12 variable cost per session, a $28 contribution margin. That business needs 2,143 sessions a month, about 71 a day, before it earns a profit, which shows why high fixed-cost formats need either high volume, high prices, or both to reach break-even inside a reasonable timeframe.

How to improve this metric

• Raise the price per unit. Even a small increase widens the contribution margin and lowers the number of units needed to break even, as long as demand holds.
• Cut variable costs per unit. Renegotiate supplier contracts, reduce material waste, or switch payment processors to shrink the cost that scales with every sale.
• Trim fixed costs. Review recurring subscriptions, renegotiate rent, or move to a leaner staffing model before assuming the only fix is selling more; a free accounting software setup makes these recurring costs easier to track and cut.
• Track the numbers monthly. Fixed and variable costs drift over time; recalculating the break-even point after every pricing or cost change keeps the target current rather than stale.
• Watch the margin alongside break-even. A lower break-even point does not always mean a healthier business; pair it with the profit margin calculator to confirm overall profitability, not just the point where losses stop.
• Bundle or upsell to lift average revenue per sale. Increasing what each customer spends per transaction has the same effect as a price increase on the break-even calculation.

Benchmarks and context

There is no universal break-even target, since fixed costs and pricing vary enormously by industry. What matters is speed: the U.S. Small Business Administration advises founders to work out their break-even point before launch, so they know the exact sales volume needed to cover every cost. According to the SBA Office of Advocacy, only about half of new US establishments survive five years and roughly a third survive ten years, which is why reaching break-even quickly is so important, a pattern also visible in the small business trends report for 2026.

Break-even also connects to customer lifetime value, or CLV: a common rule of thumb is that CLV should run at least three times customer acquisition cost, a 3:1 CLV:CAC ratio, though the right multiple depends on the industry. Reaching break-even faster preserves the cash needed to build toward that ratio, which is why SCORE, the SBA's nonprofit mentoring partner, offers free break-even and financial-projection templates covering fixed costs, variable costs and contribution margin.
