Roommate Rent Split Calculator
Split rent and utilities evenly, by room size or by income, for up to six roommates, and share the result.
Monthly split
Utilities are split evenly; rent follows the method you choose. Room size uses square feet (or any consistent unit); income uses each person's take-home pay.
Estimates are for planning only and are not financial, legal or insurance advice. Rules and costs vary by state, city and lease.
Frequently asked questions
What is the fairest way to split rent?
There is no single answer. Equal splits are simplest; splitting by room size is fair when bedrooms differ; splitting by income can make sense for couples or roommates with very different pay. Agree on the method in writing.
Should utilities be split by room size too?
Most households split utilities evenly because usage is shared, which is what this calculator does.
