<prompt> Human: So, I am about to rent a house along with 6 other people, whom I all know. The total we have to pay is 3,300 utilities included every month. The house has 4 bedrooms and one master bedroom. 4 people will have a room to themselves while 2 people will share one room. I was thinking about splitting the payment percentage-wise, but not sure how. How should we split the bill evenly so that the 2 people sharing one room will pay less than every one else, but fairly? Thanks!  <response>: Everyone pays a base amount for the shared spaces, utilities, parking, etc., then each person pays their share of their room.Something like this you can still tweak it:Split rent half-and-half between shared spaces rooms: Instead of half-and-half, you could base it on the square footage of all bedrooms vs all shared spaces too Shared spaces 1,650. 1650 6 275 per person Rooms 1,650.Lets assume the master bedroom is larger and has a larger closet, etc. and that the other rooms are the same size. A fair split may look like this: 300each for the 4 bedrooms and 450 for the master bedroom 1650. Feel free to redistribute this based on the relative size of each of the 5 rooms. The master could be twice as much as the other bedrooms if its twice as big.Now calculate what each person pays by adding the shared space amount and their bedroom amount. The two people who share a bedroom split their bedroom amount evenly.
