I think that gets abit ugly doing it like that. You all signed the lease therefore should be paying the bills every month. In a circumstance like this where one person stays and ramps up the bill by 200$ they should pay more. But I wouldn’t be counting days people stayed in the apartment, that gets abit political.
I get where you’re coming from, but it’s just sounds a bit unfair to the other four people that they have to pay for something they didn’t contribute towards at all. It just feels like the one roommate racked up the bill like that because they were relying on the others to bail them out and it’s unfair that the others are stuck with this unexpected expensive bill because this one person is being stupid.
Not how it works. All of the appliances would have been on if no one was there. The electric bill wouldn’t have been 0$ if no one was there. You expect the roommate to be in the apartment with no AC on all summer? It’s the other people’s issue that they aren’t there. Not saying it should be a 20% split between all 5, but a compromise should be met.
