How to split rent fairly: 4 methods with real numbers
Quick answer
Split rent equally when the rooms are close in size and quality. When they are not, use square footage, income or feature points. On a $2,700 apartment with rooms of 180, 140 and 120 square feet, the biggest room pays between $900 and $1,296 depending on the method, so pick one before anyone signs the lease.
Key points
- Equal is fair when the rooms are close in size and quality. Otherwise weight the rent by area, income or feature points.
- On a $2,700 apartment, the 180 square foot room with the ensuite pays $900 equal, $1,104.55 by area, $1,125.00 by income and $1,296.00 by feature points.
- Choose a gap you will not argue about, such as $50 a month. If the area split moves nobody more than that from equal, split equally.
- In EvenOut, record rent with the Shares split, using square feet, income or points as the shares, then set it to repeat monthly.

Should you split rent equally or by weight?
Split equally when the rooms are close in size and quality, and by weight when they are not. A weighted split asks each person to pay for the space they get or for what they can afford, and an equal split asks for neither.
Here is a test that settles most cases. Work out the weighted split first, then compare each person’s amount with the equal share. Say your group decides a difference under $50 a month is not worth an argument. If nobody moves more than $50, split equally. In the example below, the biggest room moves $204.55 away from equal, so weighting earns its place.
What does each method give on the same apartment?
Say three roommates rent a $2,700 apartment. Ana’s room is 180 square feet with an ensuite, and she takes home $5,000 a month. Ben’s room is 140 square feet and he takes home $4,000. Cy’s room is 120 square feet and he takes home $3,000.
| Method | Ana (180 sq ft, ensuite) | Ben (140 sq ft) | Cy (120 sq ft) |
|---|---|---|---|
| Equal | $900.00 | $900.00 | $900.00 |
| By square footage | $1,104.55 | $859.09 | $736.36 |
| By income | $1,125.00 | $900.00 | $675.00 |
| By feature points | $1,296.00 | $756.00 | $648.00 |
| Half equal, half by points | $1,098.00 | $828.00 | $774.00 |
Every row adds up to $2,700.00. Ben pays exactly the equal share under the income method because his $4,000 is the average of the three incomes. Ana’s amount runs from $900 to $1,296, a spread of $396 for the same room.
How does each method work?
Each one is a fraction of the rent, so the arithmetic is one multiplication and one division.
- Equal. $2,700 divided by 3 is $900.00 each.
- Square footage. The rooms total 180 + 140 + 120 = 440 square feet. Ana pays $2,700 × 180 ÷ 440 = $1,104.55. How to measure, and what to do about the living room and kitchen, is in how to split rent by room size.
- Income. Take-home pay totals $12,000. Ana pays $2,700 × 5,000 ÷ 12,000 = $1,125.00. The full method is in how to split rent based on income.
- Feature points. Give each room one point per 10 square feet, which is 18, 14 and 12, then add points for what you value. An ensuite is worth 6 here, so Ana has 24 points and the total is 24 + 14 + 12 = 50. Ana pays $2,700 × 24 ÷ 50 = $1,296.00. Pricing a single feature is covered in how much more the master bedroom should pay.
- A blend. Half the rent, $1,350, is split equally for $450 each. The other half goes by points: $648.00 for Ana, $378.00 for Ben and $324.00 for Cy. Ana’s total is $450 + $648 = $1,098.00. A blend suits a group where one method alone feels too harsh.
Which method should you choose?
Pick the one that matches what is actually different between the rooms and the people.
- Rooms alike, incomes alike. Split equally. Nothing else is worth the paperwork.
- Rooms differ a lot in size. Use square footage, and agree beforehand whether closets and ensuites count.
- Incomes differ a lot. Use income. It needs everyone’s take-home pay, or at least the percentages that come from it, so use it only if everyone is comfortable sharing.
- Rooms differ in more than size. Use feature points. Light, noise, a private bathroom and a closet all fit, and the points list is something everyone can read and challenge.
- One of the roommates is part of a couple. The usual question is whether the couple pays for one room or one and a half. How to split rent with a couple covers it.
How do you record rent in EvenOut?
EvenOut can split an expense by shares, so any of the weights above can go in as the shares.
- Create a group of the type Household (“Rent and bills”) and add your roommates.
- Add an expense for the rent. Tap the “Paid by you” chip if someone else pays the landlord, and choose the date the rent is due.
- Open the split picker and choose Shares. Type each person’s shares: 180, 140 and 120 for area, 5,000, 4,000 and 3,000 for income, or 24, 14 and 12 for points. The sheet shows each person’s dollar amount under their name, such as $1,104.55, $859.09 and $736.36 for area. EvenOut splits to the cent and shares out any leftover cents rather than losing them.
- For a blend, choose Exact amounts and type $1,098.00, $828.00 and $774.00. The pill reads “All assigned” once they add up to $2,700.
- Make it repeat. Open “Photo, repeat, pending or note” and choose Repeat, then Monthly. The expense you save is the first one, and EvenOut adds each later one for you, around 9:00 in your time zone, with the same payer and split.
Setting up a repeat needs a connection, and the app has no end date for it. When the lease ends or the rent changes, open “Repeating expenses” from the group menu, choose “Stop repeating”, and set up the new amount. Expenses already added stay.
Once rent is in, each roommate sees what they owe and can settle up with the person who paid, in one payment or in parts. If someone falls behind, how to remind a roommate to pay rent has wording that works.
What should you do next?
Run the four methods for your own apartment, apply the $50 test, and write the winner and its numbers into your roommate agreement. Revisit the split at renewal, when the rent or the people change. For measuring rooms and a calculator that does the arithmetic for you, see the rent split calculator by room size.
Frequently asked questions
Do roommates have to share their income for an income-based split?
The split needs each person's percentage of the combined total, and anyone can work out the others' incomes from the percentages if they know their own. If a roommate would rather not share, use area or feature points, which depend on the rooms instead of the people.
How do you price a private bathroom in the rent?
Either give it points or agree a flat amount. In the points example, the ensuite's 6 of 50 points is worth $2,700 × 6 ÷ 50 = $324.00 a month. A flat version might move $120 a month onto that room and take $60 off each of the other two. Write down whichever you choose.
Can rent and utilities use different methods?
Yes. In EvenOut the split method is chosen per expense, so the rent can use the Shares split while the internet bill is split equally, all in the same Household group. Rent usually carries the weights because it is the big number, and small shared bills are easier equal.
