Ratio of Debt to Income

The ratio of debt to income is a formula lenders use to calculate how much money is available for a monthly mortgage payment after you meet your various other monthly debt payments.

How to figure your qualifying ratio

In general, conventional loans need a qualifying ratio of 28/36. FHA loans are a little less strict, requiring a 29/41 ratio.

In these ratios, the first number is how much (by percent) of your gross monthly income that can be spent on housing. This ratio is figured on your total payment, including hazard insurance, HOA dues, Private Mortgage Insurance - everything.

The second number is the maximum percentage of your gross monthly income that can be applied to housing expenses and recurring debt. Recurring debt includes things like auto loans, child support and credit card payments.

Examples:

A 28/36 qualifying ratio

  • Gross monthly income of $6,500 x .28 = $1,820 can be applied to housing
  • Gross monthly income of $6,500 x .36 = $2,340 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $6,500 x .29 = $1,885 can be applied to housing
  • Gross monthly income of $6,500 x .41 = $2,665 can be applied to recurring debt plus housing expenses
