Frequently asked questions
What's the fairest way to split rent?
There is no single 'fair' answer. Equal split is simplest and works when bedrooms and incomes are similar. By-room-size makes sense when one bedroom is materially larger or has private bath/balcony. By-income keeps the housing burden equal as a percentage of paycheck — useful when one roommate earns substantially more. Agree on the method before you sign, and revisit if someone's job or living situation changes.
Should utilities be split separately from rent?
Often yes. Utilities vary month to month (winter heat, summer AC); separating them keeps everyone's share accurate. Use the 'same proportion as rent' option if one roommate has a much larger space (and presumably drives more electric/gas use). Internet is usually equal-split since everyone uses it.
How do I handle common areas like the living room?
Common areas are usually folded into the rent total and split by the agreed method — not measured separately. If one roommate uses the common area heavily (works from home, hosts often) and others don't, that's usually a conversation, not a calculator output.
What about parking, storage, or pet rent?
Add-on charges should go to whoever uses them. Parking space → the roommate with the car. Storage unit → split if shared, individual if not. Pet rent → the pet owner. Don't quietly bundle these into the total rent split unless everyone agrees they're shared.
How do I handle unequal rooms in an otherwise-equal split?
Three common approaches: (1) Use the by-room-size method and accept the slight inequality. (2) Equal split, but the person in the larger room pays the security deposit. (3) Equal split, but the person in the smaller room gets a parking spot or preferred bathroom access. Talk about it — the dollar difference is usually small, but the resentment if it's not addressed is not.
