How this site is funded

Updated 7 November 2026

Right now it isn't. I built it because the contractor calculators I found were lead forms that hid the maths, and I wanted one that showed it.

What may change

The site may carry adverts, loaded only after you accept them. It may link to business bank accounts or accounting software that pay a commission if you sign up. Any such link will say so next to it, and I will only link to things I'd use myself.

What won't appear

No loans, credit cards, mortgages, investments, pensions or crypto. Promoting those is regulated, and this site stays out of it.

Commissions never change the numbers the calculators produce.
