Rent Split Calculator

Start by agreeing on what you are paying for. Shared space, such as the kitchen, living room and shared bathrooms, is used by everyone, so it is usually split evenly by person. Bedrooms are not equal, so a larger room or a private bathroom usually pays more. The calculator splits the shared part evenly and the bedroom part by each room's size, and you choose how much of the rent counts as shared.

Usually, yes. Splitting by room size is common: a larger room gives its renter more private space, so it pays a larger share of the bedroom part of the rent. The difference is often smaller than people expect, because the shared part is still split evenly.

There's no standard amount. The calculator counts a private bathroom as 40 square feet added to its bedroom, about the size of a full bathroom, so that room pays a little more of the bedroom part of the rent. If your group agrees on something else, adjust the room sizes to match.

A couple sharing one bedroom usually splits that bedroom's share between them, and each pays a full share of the shared space, since two people use the kitchen and living room. The calculator does this when you mark a room as shared by two people.

Most roommates split utilities and internet evenly by person. If one person works from home or uses much more, agree on a different split before the first bill arrives.
