How to Use This Rent Split Calculator
This free rent split calculator helps roommates divide rent and shared costs. Enter the monthly rent, add optional utilities or shared bills, then choose whether to split rent equally or based on income.
Equal Rent Split
An equal split divides rent evenly between all roommates. This is the simplest option and works well when everyone agrees to pay the same amount.
Income-Based Rent Split
An income-based split divides rent based on each roommate’s share of total income. For example, if one roommate earns 60% of the household income, they would pay 60% of the rent and shared costs.
Should Utilities Be Included?
You can include utilities, internet, parking, or other shared housing costs if everyone wants one combined monthly number. If utilities change every month, update the number whenever bills come in.
Example rent split
If total rent is $1,800 and two roommates split it evenly, each pays $900 before utilities. If one person has a larger bedroom or private bathroom, use the result as a starting point and adjust by agreement.
What the result means
The calculator gives a planning estimate. It does not replace a written roommate agreement about due dates, utilities, deposits, parking, pets, or what happens if someone moves out early.
Common mistakes
- Forgetting utilities, internet, renter's insurance, or parking.
- Ignoring obvious room differences.
- Agreeing verbally but not writing down the final split.

Rent split FAQ
Should rent always be split equally?
Equal can work when rooms and access are similar. If one person has a larger room, private bathroom, or parking space, an adjusted split may feel fairer.
Should utilities be included?
Usually utilities should be listed separately unless they are fixed and included in rent.
