Roommate Utility Split Guide: Avoid Confusion Before Bills Arrive
Utility fights start when roommates assume equal splits without writing anything down. Set expectations before the first bill arrives.
Agree before move-in
Sign a roommate agreement covering rent share, guest rules, and utilities. Attach a utility addendum listing each bill and who pays what.
Split methods that work
- Equal split for similar bedrooms
- Proportional split by square footage or bedroom size
- Named payer per utility (one person pays internet, another electric) with reconciliation monthly
Run numbers in the utility split calculator first.
Example: three-bedroom share
Total utilities ~$240/month. Roommates agree: electric split three ways, internet split two ways (third room has no desk setup). Amounts entered in the addendum before signing.
Common mistakes to avoid
- Verbal "we'll figure it out" agreements.
- One roommate on the master lease with no written sub-split.
- Not updating splits when a roommate moves out mid-lease.
