About FinanceCalco

Our approach to building trustworthy calculators.

FinanceCalco is a free, independent collection of 20 financial and everyday calculators. We built it around a single idea: when you type your salary, your mortgage, or your savings into a tool, you should be able to trust the number — and trust that the number is yours alone.

Private by design

Every calculator runs entirely in your browser. There is no backend, no database, and no account. The figures you enter are never transmitted to a server, logged, or stored anywhere we can see. When you close the tab, the numbers are gone. The only way a result ever leaves your device is if you choose to export it or copy a share link.

Built for accuracy and speed

Each tool shows its working in plain language and uses transparent, industry-standard formulas — the same amortization and compounding math a bank or spreadsheet would use. Pages are static and load instantly, so you get your answer without waiting on a heavy app.

Export and share

Real decisions involve other people. Every result can be exported to a real Excel workbook (.xlsx), a CSV file, or a clean printable PDF — and any result can be shared with a link that restores your exact inputs for whoever opens it. Amortization schedules export in full so you can keep your own records.

How we keep it free

FinanceCalco is supported by unobtrusive display advertising. Ads are kept out of the way of the tools themselves and never appear on our legal pages. That is the entire business model — we do not sell data, because we never collect it.

Important: not financial advice

These calculators are educational tools that produce estimates. They are not financial, tax, legal, or investment advice, and they cannot account for your full personal circumstances. Please read our full disclaimer and consult a qualified professional before making decisions. See also our Privacy Policy and Terms of Use.
