How to split rent fairly with roommates
Splitting rent sounds simple — divide by the number of people — but unequal bedrooms, couples sharing a room, and different move-in dates make “fair” more complicated than a straight division.
Here are the methods housemates actually use, and how to keep everyone settled month after month.

Ways to split it fairly
Split evenly
The simplest approach — best when bedrooms are similar and everyone has equal access to the space.
Split by room size
Measure each bedroom, add them up, and divide rent in proportion to each room's share of the total square footage. A bigger room pays a bigger slice.
Split by income
Some housemates agree to pay in proportion to what they earn, so the split feels fair relative to each person's budget.
Account for couples
Two people sharing one room usually pay more than a single person in their own room, but less than two people in separate rooms. Treating the couple as one room is a common compromise.
Agree it up front
Whatever method you pick, write it down before move-in. The awkward conversations happen when the method was never agreed.
Frequently asked questions
What's the fairest way to split rent?
There's no single answer. Splitting evenly is simplest, but splitting by room size or by income is often fairer when bedrooms or salaries differ. The fairest method is the one everyone agrees to before moving in.
How do I split rent if the bedrooms are different sizes?
Measure each room, total the square footage, and divide the rent in proportion to each room's share of that total. A larger room carries a larger portion of the rent.
How should a couple split rent in a shared house?
A common approach is to treat the couple as paying for one room, then let them divide that room's cost between themselves however they like.
