About Solved

Free tools. Real answers. Instantly.

What is Solved?

Solved is a free collection of everyday calculators, converters, and utilities. Whether you need to split a bill, check a mortgage payment, convert units, or balance a chemical equation, you can get an answer in seconds — no account, no download, no waiting. All unit conversions use the internationally recognised SI definitions maintained by NIST.

Every tool runs entirely in your browser. Nothing you enter is sent to a server or stored anywhere.

Who runs it?

Solved is an independent project. It is designed and maintained by a small team with one goal: make common calculations fast and frustration-free.

We are not affiliated with any government body, financial institution, or professional advisory firm. The tools on this site are for informational and educational purposes. For decisions that matter — medical, legal, financial — please consult a qualified professional.

How is it free?

The site is supported by advertising through Google AdSense. Ads help cover hosting and development costs. We do not sell your data and we do not track you beyond standard analytics.

What tools are available?

There are over 100 tools across nine categories: Financial, Health & Fitness, Math, Converters, Date & Time, Word Tools, Games, Everyday, and Developer Tools. New tools are added regularly.

Financial calculators follow standard formulas published by official bodies such as the IRS. For a thorough reference on unit conversion standards, see Wikipedia: Conversion of Units. Word-origin tools draw from authoritative etymological sources including the Online Etymology Dictionary.
