Should Roommate Bills Be Based on Room Sizes?

A 28-year-old woman thought she had a simple roommate fix on her hands: split the utility bills based on how much space each person actually uses. Her roommate, a 27-year-old who lives in the bigger bedroom, did not see it that way at all.

They’re in a spacious two-bedroom apartment, but one room is almost double the size of the other. Rent used to be split evenly when they moved in, but now that they’re sharing utilities, OP wants the electric, water, and other bills to be divided by room size, since more space means more usage. Her roommate flips out, saying rent and bills should be separate and that factoring room size is ridiculous.

What starts as a fairness calculation turns into a full-on apartment standoff.

Original Post

So I'm (28F) living with my college roommate (27F) in a spacious two-bedroom apartment. However, her room is significantly larger than mine, almost double the size.

When we initially moved in together, we split the rent equally as per usual roommate agreements. Now, as we are sharing utilities, I proposed that we split those costs based on our room sizes.

My reasoning was that she uses more space and thus more electricity, water, etc. My roommate got really upset with this suggestion.

She argued that rent and bills should be separate and that I was being unfair. She even said it was ridiculous to factor in room size when determining costs.

I feel like it's a fair proposal considering the extra space she uses. We are both working professionals, so finances are important to both of us.

Am I being unreasonable by suggesting this? I honestly don't know if I'm wrong here and really need outside perspective.

The Fairness Debate

This approach allows both parties to feel their contributions are equitable, which can lead to a healthier roommate relationship. Establishing a written agreement before moving in together can help prevent misunderstandings and resentment later.

OP’s “bigger room, bigger bills” math sounded fair to her, but her roommate heard it as an attack on their original rent agreement.

This proactive approach can help mitigate potential conflicts related to bill splitting.

When the roommate said rent and utilities should be separate, that’s when OP’s plan stopped feeling like a spreadsheet and started feeling personal.

This is similar to the AITA dispute where someone refused to share finances with a partner after expense arguments.

The argument gets even messier because both women are working professionals, so this is not some casual “we’ll figure it out later” situation.

Communication plays a vital role in resolving financial disagreements among roommates.

By the time OP asks for outside perspective, the comments are already circling the same question, how do you split utilities without turning it into a power struggle?

What would you do in this situation? Share your opinion in the comments.

Ultimately, the key to a successful roommate relationship lies in open lines of communication and mutual respect.

Regular check-ins can also help maintain a healthy dialogue, allowing roommates to voice concerns and adjust agreements as needed. With these strategies, living together can be a more enjoyable experience for all parties involved.

This scenario reveals the intricate balance between fairness and emotional ties that often defines roommate relationships.

OP might be right about the math, but their relationship might be the real casualty.
