<prompt> Human: TLDR; help me determine a reasonable way to split rent so I dont have to get waken up by my roommate who is a stomper.Hi, long time lurker here! This is going to be a long post. My roommate and I have recently had some issues due to her constantly waking me up in the morning with our sleep schedule differences she thinks stomping around the room for 1 hour in the morning to do her morning is not excessive and that it is only 1 hour of sleep that I am not getting every morning : which is very inconsiderate so I am considering switching rooms with one of my housemates. However, I dont know how the rent should be split and when we talk about it, I want to have a potential and reasonable price on rent before considering switching rooms. The situation is a little complicated so I will try to describe it as best as I can. Maybe after reading through this, you guys can give me feedback andor check my math. Currently, we have 6 housemates in a 3 bedroom apartment so there are 2 people for each room. The total rent per month is 2450 for 1572 sqft for 1.56sqft we determine the rate by square feet. I am going to leave the sqft units out for simplicity. I included the loft footage because it is split among the 4 people who use it. My numbers are probably going to be a little off but only a few small digits due to errors, I dont think it will be significantly wrong. - ROOM A 165 15 x 11 x 1.56 257.42 128.7 per person - ROOM B 123.38 119 x 106 x 1.56 192.47 2 96.24 per person - ROOM C 149.19 138 x 1011 x 1.56 232.742 116.36 per person - LOFT 130 13x10 x 1.56 202.84 people 50.7 per person - COMMUNAL AREA everything else 1004.435 X 1.56 1566.926 261.16 per person With this, my roommate and I currently live in room A and pay 389.86 128.7 261.16 each. Each person in room B pays 408.07 96.24 50.7 261.16, and each person in room C pays 428.22 116.36 40.56 261.16. In other words, the sum for each room is 779.72, 816.14 and 856.44 respectively. One of our housemates are not planning on living with us next year so there will be 5 people, instead of 6 if there is no replacement. So, the new living situation would be me taking over room B as a single and the other housemate moving into Room A with my current roommate. In addition, our total rent is being raised up 2695 so 1.71sqft. But, we can ignore the rent increase so it is easier to discuss the distribution of rent with 5 people instead of 6. I dont think it is reasonable for me to pay 816.14 for room B because the communal areas is split by 6 and not 5 so I would be paying for two peoples communal areas if that were the case. From my point of view, I think the communal spaces should be divided up by 5 and then added up each room, and then add in the loft prices however we are going to split up the loft by. Splitting the loft makes things a little more complicated because I know people dont usually split the loft up as it is communal too. Also, when I lived in a single the year before moving here, my room was about the same size as room B and I only paid 550. I talked to my neighbor who lives next door and she says the girl in the single in the smallest room only pays 600 it is the same layout. And my friend currently pays 693 in the same apartment complex to live in a single room the size of Room A so I would only take the single room if the rent was between 550 and 690; 816.14 is unreasonable. - Communal: 1566.925 313.384 per person - Room A: 128.7 313.384 442.084 per person - Room B: 192.47 313.381 505.85 - Room C: 116.36 313.381 429.741 per person this would be rent, excluding however we would split the loft. I dont know if this is reasonable, I feel like it isnt. How would you recommend splitting the rent with two doubles and one single? 800 doesnt make sense and below 600 doesnt really either, especially if the rent is going up. How should I explain to them that paying 815 is not correct? What would be a reasonable amount to pay? Is saying 630 reasonable? How should it be split it if it is by square footage? How should the other housemates determine the rent for their rooms then? Can I have some suggestions please? It would really give me some perspective and be reasonable when I bring the topic up of rent splitting.  <response>: This is insanely complicated and petty. Since your entire system is built around sq footage you should pay the full amount for room B since you want to live alone. Then you should pay the 5 way split for the other common areas.
