How Rent Splitting Works
By Room Size
Each person pays proportionally based on their room's square footage. Master bedroom pays more, smaller room pays less.
By Income
Each person pays a percentage based on their income proportion. Higher earner pays more — equitable, not equal.
Custom %
Set any custom split. Perfect when you've already agreed on specific percentages (e.g., 55/45).
Frequently Asked Questions
What is the fairest way to split rent?
The fairest way is by room size — larger rooms pay more. For equal-sized rooms, an even split works. Income-based splitting is another fair option when roommates have significantly different incomes.
How should utilities be split among roommates?
Utilities like electricity, water, and internet are typically split evenly since usage tends to be similar. However, if someone works from home or has special equipment, proportional splitting may be fairer.
Should couples pay more for rent in a shared house?
A couple usually pays more than a single person for rent, but not necessarily double. Common approaches include: 150% per room + equal split of common areas, or paying by square footage.
How do you track shared household expenses?
Use a shared expense tracker or spreadsheet. Record all shared purchases (groceries, supplies, utilities) and settle up at the end of each month. Automation apps can simplify this process.
What is income-based rent splitting?
Rent is split proportionally to income. For example, if Roommate A earns $60K and Roommate B earns $40K, A pays 60% and B pays 40% of the rent. This is common among partners or close friends.
How do you split move-in costs with roommates?
Move-in costs (deposits, first months rent, furnishing) should be discussed and agreed upon before signing a lease. Typically, everyone pays their equal share of the deposit.
What happens if a roommate moves out early?
The departing roommate should still cover their share until a replacement is found, or help find a replacement. Having a written roommate agreement upfront prevents most disputes.
Should water bills be split equally or by usage?
For standard consumption, equal splitting works. If someone takes very long showers, does extra laundry, or gardens heavily, consider usage-based splitting with a slight adjustment.
