About Uzi Tools

What We Offer

Uzi Tools is a collection of 49 free, in-browser calculators and utilities. The current library covers finance, health, math, education, conversions, and home projects. Each tool calculates in the browser, so the inputs needed for a calculation do not have to be sent to a Uzi Tools server.

Finance & Budgeting Tools

Our finance tools help you estimate mortgage payments, compound interest, SIP returns, retirement savings, take-home pay, debt payoff, budgets, ROI, break-even, discounts, profit margins, and rent vs buy. Use them to compare scenarios and plan—for exact figures or tax advice, always consult a qualified professional. Browse all finance tools.

How We Maintain the Tools

The tools are intentionally small and task-focused. We document the formula or assumptions for each calculator, explain important limitations, and keep the result visible next to the inputs so users can check the calculation themselves.

Read the calculator methods and assumptions page for the conventions behind the main tool groups.

Privacy and Trust

Tool calculations happen in your browser, so the inputs needed for a calculation are not sent to our servers. The site may use cookies or analytics for site operation and measurement; see our Privacy Policy for details. By using the site, you also agree to our Terms of Service and Disclaimer.
