<prompt> Human: Hi all, I wasnt quite sure where to post this, but since it has to do with paying rent, I thought it was somewhat personal finance related. If there is a better place to post this, let me know.Ive been living with my current roommate for the past year in a 2 bedroom 2 bathroom apartment. Both bedrooms and bathrooms are the exact same size. The only common areas are the kitchen, dining area, living room, and a small foyer area. So logically, it wasnt too unreasonable to split rent 5050.My roommate is planning to move out in a couple months. I told one of my friends about this. He and his girlfriend are now interested in moving in, and taking the empty bedroom and bathroom.My question now is whether it is still fair that we continue to pay a 5050 split on rent? As two people, they will be using the common areas more than me. For example, I cook all my meals on Sunday and only really use the kitchen once a week. They make dinner together every night.On the other hand, they are getting a bedroom and bathroom nearly identical to mine. Its tough to make the case that they should pay more for that.Edit: Info on utilities: Landlord covers gas and water. We are responsible for electric and internet. Heating and AC run on electric, not gas.Edit 2: I took out the section about incomes. Youre right, it doesnt matter.  <response>: Everyone here is saying 5050 but thats not been my experience. My friend had almost this exact situation and they split rent 403030. Ive shared rooms and been in singles with people in doubles, the norm has been that in a double you dont pay 12 the room cost, you pay slightly more.3 people in a 2-bedroom apartment is a 50 increase in occupancy, it makes sense to adjust the rent rates. The assumption is all 3 people share equal access to the common spaces, but the 2 sharing a room get a rent discount because they have less personal space.
