How it is calculated
Rent is split into a common-area share (divided equally per person) and a room share (divided by room area, then equally among the room's occupants). Bills are divided equally per head. Adjust the common-area percentage up for flats with large living rooms.
Worked example
₹30,000 rent, ₹6,000 bills, rooms of 160 (1 person), 130 (1) and 120 sq ft (2), 40% common: room 1 pays ₹11,524, room 2 ₹10,207 and each of the two in room 3 ₹7,134, against an equal split of ₹9,000 a head.
Frequently asked questions
How should flatmates split rent fairly?
Weight by room size and occupancy for the private part, and split common areas and bills equally. Attached bathrooms and balconies justify a further 5–10% premium.
Should a shared room pay less per person?
Yes: the room's share is divided between its occupants, so each pays roughly half of what a single occupant of the same room would.
How do we handle a flatmate who travels a lot?
Rent is for the space, not attendance; usage-based bills (electricity, cook) can be pro-rated if everyone agrees.
