Easy Mental Math For Rent To Income Ratio

If you’re doing some mental math, simply take an applicant’s gross annual salary, and divide it by 40.

The resulting number will represent 30% of their gross monthly salary.

In other words, the calculation represents the most a tenant can afford to pay for rent based on a 30% rent to income ratio.

Examples of This Ratio In Use

  1. If a tenant makes $80,000 in gross annual income, you would divide this by 40.
  2. The resulting number of $2,000 is the most that tenant can afford for monthly rent under a 30% ratio.

A longer way of getting to this number is by taking:

  1. $80,000 and dividing it by 12
  2. The resulting number of $6,666.66 represents their gross monthly salary
  3. Multiply $6,666.66 by 30% to get $2,000

What Does A 30% Rule Equate To In A Rent To Income Multiplier

A 30% rule is the same as saying a 3.33 (repeating) multiplier ratio.

Here’s a screenshot of those numbers matching up (look at the highlighted box of 3.3333333).

This is important to understand because if you use a 30% rule than you’re being more selective than someone who uses a 3.0x rule.


How To Apply This Information

First things first, you should set a proper rental price for your rental.

Once you know what you want to charge monthly, you can easily figure out what annual salary a tenant would need in order to meet your rent to income ratio.

For instance, if you want $1,200 in monthly rent. You can multiply that number by 40 to get a minimum gross annual salary. In this example it would be $48,000.
