How to Split Apartment Rent Fairly Between Roommates
Splitting rent 50/50 when bedrooms are different sizes or one roommate gets a private attached bathroom creates resentment. A mathematically fair rent split accounts for square footage, common living areas, and private perks like balconies and parking slots.
1. Common Rent = Total Rent x (Common Sq Ft / Total Apartment Sq Ft) / Number of Roommates
2. Bedroom Rent = Total Rent x (Private Bedroom Sq Ft / Total Apartment Sq Ft) + Perk Premiums
2. Bedroom Rent = Total Rent x (Private Bedroom Sq Ft / Total Apartment Sq Ft) + Perk Premiums
3 Essential Rules for Flatmates & Roommates
- Split Utility Bills Equally: Electricity, Wi-Fi, water, and maid services benefit everyone equally and should always be divided 50/50.
- Agree on Rental Deposit Proportions: Security deposit contributions should mirror each roommate's rent share percentage.
- Put Rent Agreements in Writing: Document the agreed room split on a WhatsApp group or shared document to prevent future misunderstandings.

What if one roommate has a parking space?
