Private by design
Everything is worked out in your browser. There are no accounts, no tracking scripts and nothing to sign up for, so what you type about your pay or your flat stays with you.
Numbers you can trace
Tax rates and public holidays come only from government pages. The pay tools use the 2026-27 tax year, and every money page links to its source with the date it was checked.
Explained, not just answered
Each tool page walks through the method, a worked example made by the same code, and the mistakes people commonly make. No frameworks or third-party scripts, so pages open fast on a slow connection.
Plain-English guides
Short explainers behind the calculators, with worked examples. A tool only goes live once its figures are checked against an official source, and guides follow the same rule, so this section is still filling up. Start with the guides page, or read how the site works. Everyday Tools is run by an independent publisher in New Zealand.
