How We Calculate Your Rent Split
Our Rent Split & Income-Based Calculator uses a proportional distribution method to ensure that financial contributions remain fair relative to each person's earnings.
The Simple Math Behind It
The calculation determines each roommate's share by dividing their individual income by the total household income, then multiplying that percentage by the total monthly costs.
Share = (Individual Income / Total Household Income) × Total Monthly Cost
- Total Household Income: The sum of all individual monthly incomes entered.
- Proportional Share: Each roommate's percentage of the total household earnings.
- Final Cost: The resulting dollar amount each person is responsible for.
A quick example: If the total rent is $2,000 and Roommate A earns $3,000 while Roommate B earns $2,000 (total $5,000), Roommate A pays $1,200 (60%) and Roommate B pays $800 (40%).
