UK Mortgage Repayment Calculator
I was tired of using fairly lacklustre mortgage calculators online, or having to dig out a spreadsheet every time I wanted to sanity-check a number, so I thought I’d make my own web version with the help of ChatGPT. Quite often I don’t just want one result, I want to see what happens if the inputs move around slightly, so I added sliders that let you tweak the values and see the result recalculate instantly.
