Templates for Roommates.

Sharing a home is the version of running one where every decision has a counterparty in the next room. Nothing is governed by a lease and nobody is in charge — so the house runs on assumptions until the assumptions stop matching. These are the files that make them explicit.

Three questions a shared house has to answer

What did we agree? Not what everyone remembers agreeing — what is written down, who confirmed it, and when. Who owes whom? Not roughly; exactly, with the arithmetic visible so nobody has to trust anybody's mental math. Whose turn is it? Decided once by a rule everyone signed up to, rather than renegotiated every week by whoever minds the mess least.

Most houses answer all three in a group chat, which is a terrible ledger: no totals, no structure, and no memory anyone can search at the moment it matters. Almost every roommate argument turns out to be an argument about a missing record rather than about money or noise.

Start free, no signup: the Roommate Bill-Split Calculator settles one month of shared costs in your browser and tells you who pays whom — the same method as the full shared-household kit.

Working something out now? Read splitting rent and bills with roommates fairly, or what a roommate agreement is and what it can and can't do. Deciding how to track it all? Compare a spreadsheet vs. a bill-splitting app. Dealing with the landlord rather than each other is a different problem — that's for renters.

Household records and arithmetic, not legal advice. A written understanding between housemates is not a lease and does not change your rights or obligations under one, and a balance in a spreadsheet is not a legal claim on anyone. Deposits, notice periods, subletting, and what a landlord may deduct are set by state and sometimes local law and vary sharply. Where real money or someone's housing is at stake, talk to a local attorney, a tenants' service, or a legal-aid organization near you.
