Tools to get more done.

DoMoreKit is a free online toolkit of calculators, converters and developer utilities. We build simple, accurate tools for people who need a quick answer without signing up, installing anything or wading through clutter.

What you can do here

The toolkit currently has 42 tools across money and finance, business, freelancing, everyday tasks and development. Each tool page explains the formula it uses, shows a worked example and answers common questions, so you can understand the result and not just copy it.

How we work

• Private by default. Calculations run in your browser. The values you type into a tool are not sent to our servers.
• Transparent formulas. Every calculator shows how its result is produced.
• Built for everyone. The tools are designed for a global audience, not a single country.
• Honest about limits. Our results are estimates for general information. Read the disclaimer before relying on them for financial, tax or legal decisions.
