How to Calculate Rent to Income Ratio?

The following example problems outline how to calculate Rent to Income Ratio.

Example Problem #1:

  1. First, determine the total monthly rent ($). 
    • The total monthly rent ($) is given as: 3,000.
  2. Next, determine the monthly gross income ($). 
    • The monthly gross income ($) is provided as: 7,000.
  3. Finally, calculate the Rent to Income Ratio using the equation above: 

RIR = R / I 

The values given above are inserted into the equation below and the solution is calculated:

RIR = 3,000 / 7,000  = .428:1 (rent:income)


Example Problem #2: 

For this problem, the variables required are provided below:

total monthly rent ($) = 2,000

monthly gross income ($) = 5,000
