Debt/Income Ratio

Lenders use a ratio called "debt to income" to determine your maximum monthly payment after you have paid your other recurring debts.

Understanding your qualifying ratio

Typically, conventional loans need a qualifying ratio of 28/36. FHA loans are a little less restrictive, requiring a 29/41 ratio.

The first number is the percentage of your gross monthly income that can be spent on housing costs. This ratio is figured on your total payment, including homeowners' insurance, HOA dues, Private Mortgage Insurance - everything.

The second number in the ratio is what percent of your gross income every month which can be applied to housing expenses and recurring debt. For purposes of this ratio, debt includes credit card payments, car loans, child support, and the like.

Some example data:

With a 28/36 ratio

  • Gross monthly income of $3,500 x .28 = $980 can be applied to housing
  • Gross monthly income of $3,500 x .36 = $1,260 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $3,500 x .29 = $1,015 can be applied to housing
  • Gross monthly income of $3,500 x .41 = $1,435 can be applied to recurring debt plus housing expenses
