Ratio of Debt-to-Income

Your debt to income ratio is a tool lenders use to determine how much money is available for a monthly home loan payment after you have met your various other monthly debt payments.

Understanding your qualifying ratio

For the most part, underwriting for conventional mortgage loans needs a qualifying ratio of 28/36. FHA loans are less restrictive, requiring a 29/41 ratio.

The first number in a qualifying ratio is the maximum percentage of your gross monthly income that can be applied to housing costs (including loan principal and interest, private mortgage insurance, homeowner's insurance, taxes, and HOA dues).

The second number is what percent of your gross income every month that can be applied to housing expenses and recurring debt. Recurring debt includes auto loans, child support and monthly credit card payments.

For example:

With a 28/36 ratio

  • Gross monthly income of $2,700 x .28 = $756 can be applied to housing
  • Gross monthly income of $2,700 x .36 = $972 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $2,700 x .29 = $783 can be applied to housing
  • Gross monthly income of $2,700 x .41 = $1,107 can be applied to recurring debt plus housing expenses
