A calculator to see if getting a Miles pass would save money

Hi all, I made a calculator to see if getting a Miles pass actually saves any money (spoiler: its only worth it if you use miles more than once or twice a week). The calculator is based on a google sheet, if you want to play with it click here and it should prompt you to make your own copy. The annual pass prices in there rn are the black friday deals, you'll have to update the price yourself once the deal is over.

I originally posted this in r/berlin but the Warmduscher mods deleted it (probably paid for by Miles)
