Split rent fairly between roommates — equally, by room size, or by income. Add shared utilities and get an instant, ready-to-share breakdown for everyone.
A rent split calculator helps roommates figure out exactly how much each person should pay toward the total monthly rent. Instead of guessing or splitting everything evenly by default, it lets you choose a method that reflects how the space and cost are actually shared.
The total rent is divided evenly across every roommate. This works best when bedrooms are similar in size and everyone earns a comparable income.
Each roommate's share is based on the square footage of their room relative to the total. A larger room means a larger share of the rent, and a smaller room means a smaller share.
Rent is divided proportionally based on what each roommate earns, so no one is paying a share of rent that strains their budget more than it strains anyone else's.
This calculator always splits utilities evenly across all roommates, separate from whichever rent method you choose, since shared costs like electricity and internet are usually consumed similarly by everyone in the home.
