How do you split rent fairly between roommates?

There is no single right answer, but the three common approaches are an even split (everyone pays the same), a split by income (each person pays a share proportional to what they earn), and a split by room size (whoever has the larger or better room pays more). This calculator does all three to the cent so you can compare them and pick what feels fair.

How do you split rent by income?

Add up everyone's monthly income, then each person pays their income divided by the household total, times the rent. If two roommates earn $5,000 and $3,000, the first pays 62.5% of the rent and the second pays 37.5%. Switch this calculator to the 'By income' method and it does the math for you.

Does coQuarters hold or move our money?

No. This calculator just does the math, and the coQuarters app only records who owes whom. When it is time to settle up, coQuarters builds a one-tap Venmo or Cash App link for the exact amount and you pay each other directly.

Can I share the split with my roommates?

Yes. The calculator saves your inputs in the page link, so tap 'Copy shareable link' and send it. Whoever opens it sees the same rent, roommates, and split you set up.

Three fair ways to split rent

Split evenly. The simplest approach: take the total rent and divide it by the number of roommates. It works best when the bedrooms are similar and everyone earns roughly the same. This calculator rounds to the cent and hands any leftover penny to one person so the shares still add up exactly.

Split by income.When one roommate earns a lot more than another, an even split can feel lopsided. Splitting by income means each person pays a share proportional to what they earn, so the rent takes a similar bite out of everyone's paycheck. Enter each monthly income and the tool works out the percentages.

Split by room size. If one bedroom is bigger, has a private bathroom, or better light, the person in it often pays more. Enter a room size in square feet (or any relative weight) for each roommate and rent is divided in proportion.

Whichever you choose, the goal is a number everyone agrees is fair. Once you settle on a split, coQuarters can track it every month, log who actually paid, and keep the running balance so you never have to redo the math.
