About EveryCalc

EveryCalc is a collection of free online finance calculators built around a simple idea: important money decisions should not require a spreadsheet degree. Buying a home, refinancing a loan, or planning for retirement all come down to a handful of well-known formulas — we just make them fast, clear, and available to everyone.

What makes us different

Private by design. Every calculation runs entirely in your browser using JavaScript. The numbers you type never leave your device — they are not sent to our servers, stored, or sold, because we never receive them in the first place.

No accounts, no paywalls. Every tool is free with no signup and no usage limits. We keep the lights on with advertising, which is why you will see ads on our pages — never pop-ups that block the tools, and never paywalled results.

Real math, explained. Each calculator page shows the formula it uses and a worked example, so you can verify the results and actually understand what is happening with your money — not just trust a black box.

A note on accuracy

Our calculators use standard financial formulas — the same amortization and compounding math that banks and lenders use. Results are estimates for planning purposes. A lender's final figures may differ slightly due to fees, rounding, exact day-count conventions, and products with features our simplified models do not capture (such as adjustable rates). Nothing on this site is financial advice; for big decisions, talk to a qualified professional.
