About Baichdi

Baichdi is a free collection of calculators and plain-English guides for the sums people do at work and at home: take-home pay, tax, VAT, mortgage and loan repayments, savings, end-of-service benefits, time zones and more. We also cover technology and AI news that affects the tools people use every day.

Who it’s for

We build for people in the United States, the United Kingdom, Canada, Australia, New Zealand, Europe, the United Arab Emirates and Saudi Arabia. Many of our readers have lived or worked in more than one of these countries, so each calculator uses the rules of the country you choose rather than assuming one.

What makes a Baichdi tool

• It works in your browser. What you type isn’t sent to us or stored.
• It shows the working, not just the answer, and the guide underneath does the same sum by hand.
• It names the tax year or rules it uses and links to the official source.
• It’s free, with no sign-up.

You can read how we check our numbers, including how often we review rates and how to report a mistake.

How the site is paid for

Baichdi is funded by advertising. Advertisers have no say over what we write or how the calculators work, and we don’t accept payment to recommend products.
