About

EasyToolbox is designed, built and maintained by Muhammad Abdullah Awais, a full stack developer. Every tool on the site, and every figure or word list it relies on, is checked by Muhammad Abdullah Awais against its sources before it is published.

Most online calculators give a number and nothing else. This site is built on the idea that a figure is only useful when you can see where it comes from: which law sets the rate, which formula produces the result, and when it was last checked.

Each tool is written for its own market and in its own language, with that country's rules, vocabulary and currency, rather than translated from English.

Every tool follows the same four rules, so each figure can be traced to its source and checked.

• Every rate, threshold and legal limit lives in one data file per tool, with the date it was verified.
• The calculator, the worked examples and the tables on each page are all generated from that file, so they cannot disagree.
• Automated tests check every formula against reference values, and a page that fails them is not published.
• Every tool, from the calculators to the word tools and games, runs in your browser, so nothing you enter is sent anywhere.

The methodology page describes each step in full.

The site is free. It is not paid by any lender, bank or product provider and has no affiliate links. If advertising is added in future, it will be clearly separated from the tools and will never influence a result.
