Equal: Rent ÷ Number of Roommates
Room-Size: (Room Size + Shared ÷ Roommates) ÷ Total Sq Ft × Rent
Income-Based: (Personal Income ÷ Total Income) × Rent
No single method is 'perfect'—it depends on what roommates agree is fair. Common methods: (1) Equal split — simplest, everyone pays the same. (2) By room size — larger rooms pay more. (3) By income — proportional to earnings. (4) Hybrid — 50% equal + 50% room-based.
Calculate each room as a % of total rentable area. Shared spaces (kitchen, bathroom, living room) are split equally among all. Example: 4 rooms (100, 120, 140, 160 sq ft) + 300 shared = assign shared proportionally to room sizes.
Depends on your lease. Some split rent + utilities together. Others split rent by room and utilities equally. Get explicit agreement upfront to avoid disputes.
