About Utility Hub

Utility Hub is a small collection of free online tools for everyday tasks: a countdown timer and calculators for percentages, discounts, tips, sales tax, averages, and fractions. Each tool does one job, opens instantly, and needs no account or download.

How the tools are built

• Every tool runs in your browser. What you type into a calculator or timer stays on your device and is not sent to a server.
• Calculations avoid the small rounding errors computers can make, so 0.1 + 0.2 shows 0.3, and money amounts are rounded to the cent in a way that always adds up.
• Each tool page explains how the result is worked out, with worked examples you can check by hand.
• Pages work on phones, tablets, and desktops, and every control can be used with a keyboard or a screen reader.

Accuracy and limits

The tools are checked against worked examples, but they are general-purpose helpers, not financial, tax, or professional advice. For anything important, such as a tax filing, confirm the result with an official source.
