Ahad Noor
Founder and maintainer of Momentix · Profile last updated 13 November 2026
Muhammad Ahad Noor (known as Ahad Noor) builds and maintains Momentix, including its calculators, converters and the guides on this site.
What am I responsible for here?
- Building each calculator and writing the explanation, formula and worked example that appear under it.
- Keeping the tax rates and thresholds in the calculators in line with the official source pages, and recording the date each was checked. The sources are listed on the methodology page.
- Checking that the worked examples in every guide show the same figures as the matching calculator, which is what the site's automated tests do.
- Answering corrections and questions sent through the contact page or to momentix.online@gmail.com.
How are the numbers checked?
Figures in the guides are produced by the same code the calculators run, then covered by tests, so an article cannot quietly drift from its tool. Official rates come from GOV.UK and similar primary sources. The full method, the sources and the corrections policy are on the methodology page.
