What is a break-even analysis calculator?

A break-even analysis calculator is a free online tool that helps you calculate the units and revenue needed to cover fixed costs at a given price and variable cost. Break-even is the point where total revenue covers total costs. It runs entirely in your browser with instant results and no sign-up.

Is this a substitute for an accountant?

No — these calculators provide quick estimates for planning and decisions. For tax filings, financial reporting, or formal valuations, use a CPA / CFA.

What accounting basis is assumed?

Most ratios assume GAAP figures from financial statements. For cash-basis or tax-basis filings, adjust the inputs accordingly.

How current are the formulas?

Core finance formulas (DCF, IRR, depreciation methods, payment math) are stable. Tax-specific calculators (like-kind, repossession) reflect post-TCJA / 2025 rules where applicable.

How it's calculated

How the break-even analysis works

Break-even is the point where total revenue covers total costs.

break-even units = fixed costs / (price − variable cost)

break-even revenue = units × price

Accuracy

How accurate is this break-even analysis?

Every formula on this site comes from an established, published source for its field — standard references in mathematics, finance, health, and engineering, not invented in-house. The math is implemented as a pure TypeScript function and tested against published reference values before going live. See the Methodology page for the full sourcing process.

Results are mathematically correct for the inputs provided. They are estimates only— real-world outcomes depend on factors specific to your situation, such as fees, taxes, timing, local rules, and assumptions that can change after the calculation date. See the Disclaimer for the limits on what to rely on a result for.
