A NOTE BEFORE YOU PLAN

Useful numbers, thoughtfully made.

Finite is a free collection of quick, practical calculators for everyday money questions. Everything runs in your browser, with no account, registration, or payment required. The aim is simple: make common financial math easier to understand and easier to revisit.

Each tool is built around a specific formula and reviewed against example calculations, but no calculator can capture every detail of a real financial situation. Treat the results as estimates for learning and planning, not as financial, tax, legal, or investment advice. Rates, rules, fees, and lender policies can change.

The Crypto mortgage calculator pulls live market prices from a third-party data API so figures stay current, but crypto prices move constantly — always confirm the exact price with your exchange or lender before transacting. Some calculators are broadly useful anywhere, while others depend on local rules.
