Split rent by room — not just headcount

Figure out a fair rent split

Splitting rent equally sounds fair, but it rarely is — someone always ends up with the tiny room, no closet, or the window facing a brick wall. FairRentSplit calculates what each roommate should actually pay based on room size, a private bathroom, closet space, natural light, and outdoor access. Adjust the inputs below and see a fair split in real time.
