Splitting bills in a student house gets messy fast: gas, electric, broadband, water, and a TV licence rarely land on the same day or the same person. The Bills Splitter below takes your total monthly bills, your housemate count, and any special cases (single-person council tax, room-size splits, split broadband), then outputs exactly what each person owes and when. Screenshot the output and drop it in the house group chat, the argument is over before it starts.
