Break-Even Analysis Calculator

Break-even point is calculated as: Fixed Costs ÷ (Price Per Unit - Variable Cost Per Unit). The denominator is called the 'contribution margin', the amount each unit contributes toward covering fixed costs. Once fixed costs are covered, each additional unit sold is profit.

This calculator uses 3 inputs — enough to capture the meaningful drivers of the answer without overwhelming the user. Expect the result to be defensible for most planning and screening contexts; for material decisions, run sensitivity on the discount rate or growth rate to bracket the realistic range of outcomes.

Operations tools answer unit-economics questions: at what price and volume does this product, service line, or location stand on its own? Break-even analysis is the simplest and most widely used form of this calculation, and the contribution-margin formula at its core is the same math used by Fortune 500 finance teams and three-person startups alike.

For live macroeconomic context that flows into many of these calculations — current Treasury yields and the federal funds rate when discounting cash flows, prevailing inflation when projecting revenue, current wage benchmarks when modeling labor cost — pair the result with the live readings on the indicators dashboard. Authoritative free sources for those inputs include the Federal Reserve’s FRED database for rates and macro series, the U.S. Bureau of Labor Statistics for wage and inflation data, and SEC EDGAR for public-company financial disclosures.

Use break-even analysis when launching a new product, evaluating pricing changes, deciding whether to enter a new market, or assessing whether a business unit is viable. It answers the fundamental question: 'How much do we need to sell to not lose money?'
