How to Calculate Roommate Rent Split

What is Roommate Rent Split?

The Roommate Rent Split Calculator fairly divides total rent among roommates proportional to room size in square feet. Common fair-split additions: bathroom access (en-suite premium), parking, closet size. Pure square footage is the simplest defensible starting point for negotiation.
