Ratio of Debt-to-Income

Lenders use a ratio called "debt to income" to determine the most you can pay monthly after you have paid your other monthly debts.

How to figure the qualifying ratio

Most underwriting for conventional mortgage loans requires a qualifying ratio of 28/36. FHA loans are a little less strict, requiring a 29/41 ratio.

The first number in a qualifying ratio is the maximum percentage of your gross monthly income that can go to housing (this includes principal and interest, private mortgage insurance, homeowner's insurance, property tax, and homeowners' association dues).

The second number is the maximum percentage of your gross monthly income that can be spent on housing costs and recurring debt. For purposes of this ratio, debt includes credit card payments, car payments, child support, and the like.

Some example data:

With a 28/36 qualifying 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
