How to talk about rent with housemates
A short guide — not legal advice. Use alongside a tool like RoomieMath.
Pick the right moment
Avoid bringing up rent in the middle of an argument. Choose a calm time when everyone can sit for twenty minutes—after dinner, or a weekend morning—so nobody feels ambushed.
Start from shared facts
Agree on the basics first: total rent, what is included (bills, parking, storage), and what counts as a “bedroom” for each person. Write those numbers down so the conversation stays concrete.
Compare rooms, not people
Frame the discussion around room size, light, noise, and bathroom access—not who “deserves” more. That keeps it less personal and easier to adjust if someone moves in or out later.
Decide what “fair” means
Some households want strict proportionality; others weight a ensuite or a quiet floor more. You can use weights in RoomieMath to reflect what matters to your group, then look at the numbers together.
Use a written outcome
Once you agree, put the split in writing (email or message thread) and reference your tenancy or house rules if needed. If you use a share link from RoomieMath, everyone can reopen the same scenario and see how the numbers were derived.
If you get stuck
A neutral third party (e.g. a landlord mediation service, or a housemate who is not in the room) can help. The calculator is a starting point for negotiation, not a substitute for professional advice where your contract or local law requires it.
