Since the OP hasn’t bothered to come back, I guess we can assume that she and her roomies figured it out on their own.
StG
I’m just assuming quadruple murder-suicide.
That’s probably the most fair I’ve seen and close to what I figure:
1/3 rent for bathrooms. Each person is sharing one of two bathrooms so everyone pays $83.33
1/3 rent for common space. Everyone shares this equally so everyone pays $83.33.
1/3 rent for bedrooms. 3 bedrooms @ $111.11/bedroom. The couple shares a bedrooms so they split the $111.11.
That gives me:
Room #1 $444.41 ($222.21/person)
Room #2 $277.77
Room #3 $277.77
If however the master bedroom is bigger or master bath is bigger than the others then an adjustment would be closer to WhyNot’s.
October 2012 is the month of people signing up to make one post about problematic relationships before disappearing. July was the month of nuts. June was when all of the cool new people showed up.
I haven’t figured August out yet.
I see what you did there.
Not just me. tapu and JackieLikesVariety are two that come immediately to mind, but there are at least a few others.
Fair enough. Welcome to the SDMB, by the way 
Hi, I think that there is no perfect formula to derive at the exact amount of rent you should pay but I think it is fair that since your boyfriend is now moving in with you, you and your bf pay a higher rent then the other two girls. I think only splitting the utilities bill in 4 parts may not be the solution that your rommies will agree to. You have to site with them and find a solution amicably with their consent.
I’m not participating in this thread. I just showed up to brag that I don’t have to have roommates and lord it over those who do.
Ditto!
Seriously now, I’m with everyone but the OP here. The only conceivable reason she has to be upset is they changed their minds mid-way through the agreement. That kinda sucks, but that’s how it crumbles cookiewise, plus it’s not like their request is in any way unfair.
Me too.
I was hoping for the Nobel in Physics but I guess I will have to settle for “never needed and most of the time did not have a roommate” prize.
I would like to predict a [sad update] in about 6 months from the OP when her boyfriend breaks up with her and moves to a new place with her fun roomies.
Wait, try this: bf moves to new place with her fun roomies, and borrows money from her to pay rent, since he’s between jobs.
And/or fucks at least one of the roomies while they’re still stuck in the lease so they have to put up with each other for a few months until the lease is up.
(Never be the third wheel in a dating roommate situation. I knew a few college couples who had another roommate in the same rented apartment/house, then the relationship broke up well before the lease was up and there was much drama and awkwardness.)
Here’s my prediction:
The OP is never going to return. She has a grand total of one post on this board - the OP itself. Why do people keep trying to engage her - she’s clearly not coming back.
Well duh. We’re clearly here for our own amusement at this point.
My 2 cents as a mathematician that deals a lot with non-mathematicians.
First of all, dispence with any equtable arrangements based on math. Even if you understand
I guaranty your roommates wont understand it.
The only thing that will be considered fair by them is if you and boyfriend pay 50% and they each pay 25%.
I think that’s probably the case for most all of our posts, even for threads where a brand new guest member DOES come back and respond.
We obviously pissed her off by saying that they should split rent 4 ways evenly.
