How Does the Square Footage & Amenity Formula Work?
Most roommate disputes start because one person has a huge room with a private bathroom while another has a tiny box room, yet they split the lease down the middle. This calculator uses the industry-standard Split-Common Hybrid Method:
By default, 30% of total rent pays for the kitchen, living room, and shared halls. Because everyone has equal access to these spaces, this portion is split 100% equally among all roommates.
The remaining 70% of rent is dedicated to bedrooms. Each bedroom pays for its exact percentage of total private square footage. If your room is 40% of the bedroom space, you pay 40% of the private pool.
Perks like private en-suite bathrooms (+$150) and balconies (+$75) are adjusted against the apartment average so the sum of all rooms always adds up to exactly 100% of your landlord's lease.
