Split rent in proportion to income
Each person pays the same share of their income, so a big pay gap doesn’t turn into a big gap in what is left over each month.
Monthly or yearly, take-home or gross: use the same kind for everyone; only the ratio matters.
The link holds the whole split, including the incomes. Nothing is stored on our server until you make it a household.
The numbers, step by step
Ana and Ben share a $2,200 one-bedroom. Ana takes home $6,200 a month and Ben $3,800, so together they earn $10,000. Each pays the share of the rent equal to their share of the combined income.
- Ana pays $1,364.00: 62% of the combined income → 62% of the rent.
- Ben pays $836.00: 38% of the combined income → 38% of the rent.
- Total: $2,200.00, exactly the rent.
Names and amounts are samples. Change any number in the calculator above and the result updates.
Worth agreeing in writing
Agree on which income figure you use (take-home or gross) and how often you update it; both choices change the answer.
Keep it running
Turn this into a household: rent posts at the agreed split each month, bills split by days home, and housr works out who owes whom. Roommates join with a link and a name.
Make it a householdWhen this split is fair, and when it isn’t
Fair when
- You are a couple or close partners pooling a life, and you would rather both have similar money left over than split the rent down the middle.
- The incomes you enter are the ones you both agree to use: take-home pay, not salary before tax, if that is what you actually live on.
- You revisit it when either income changes, the same way you would revisit a budget.
Not so fair when
- Between roommates who are not partners, paying more because you earn more usually feels like a subsidy rather than fairness; a split by room is the more common choice there.
- If the higher earner ends up paying almost all of it, both people can lose the sense of having a stake. A cap (see the capped scenario) keeps the proportion while limiting the top share.
- Incomes are sensitive. The share link includes them, so send it only to the people they belong to.
- Whatever you agree between yourselves, the landlord goes by the lease. Texas’s Attorney General puts it plainly: “The most important source of information about your relationship with your landlord is your rental agreement.”
This is general information about splitting costs between yourselves, not legal advice. Your lease and your state’s law decide what you owe the landlord.

Split by income, but cap the top share
A pure income split can leave one person paying almost everything. A cap keeps the proportional idea and stops the top share at a level you choose.

Per room is unfair to the single person; per person is unfair to the couple, who share one bedroom. The hybrid splits the shared space by heads and the bedrooms by size.

There are three common answers, and each has a real argument. The hybrid (shared space per person, bedroom per room) is the one most households settle on, and the calculator shows why.
