About FinanceTools

FinanceTools was built to provide clear, fast, and trustworthy financial calculators for everyday use — whether you're planning savings, comparing loan options, or just want to run a quick number.

Our principles

• Privacy first. All calculations run locally in your browser. We do not store your inputs or results.
• Transparency. Every calculator page explains the formula it uses, so you can verify the results yourself.
• Simplicity. No sign-ups, no paywalls, no bloated interfaces. Just the tool you need.
• Honesty. Results are estimates. We clearly disclaim that outputs are informational and not financial advice.

How the calculators work

Each tool is written in plain JavaScript and executes entirely on your device. When you type a number into an input field, the result is computed instantly in the browser — nothing is sent to a server. This makes the site fast and keeps your financial data private.
