10-Month-Old Calculator Website Already Earning $7.5K/Year

My Pay Calculator
  • My Pay Calculator

  • Website
  • $7500 estimated annual revenue

MyPayCalculator.co.uk is a simple website to help people in the UK 🇬🇧 calculate their take home pay.

The domain was registered in Dec 2023 and it only has 22 pages indexed on Google.

But the site is already getting an estimated 150k visitors per month.

It’s monetized with display ads, and the Google Adsense calculator pegs its earnings at $7500 per year 🤑

Very impressive for such a new, small, niche website. 

And I expect it will keep growing steadily 📈

The idea: build a site like this for another country.

There could actually be one for every country, but of course the earning potential would be higher with big populations.

Even if you’re not familiar with tax laws or coding, you could build this pretty quick with AI 🤖

For inspiration, see some of the cool things people are building with AI in this X thread.
