Ratio of Debt-to-Income

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

How to figure the qualifying ratio

Typically, conventional mortgages require a qualifying ratio of 28/36. FHA loans are less strict, requiring a 29/41 ratio.

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

The second number is what percent of your gross income every month that should be spent on housing expenses and recurring debt. Recurring debt includes things like auto loans, child support and monthly credit card payments.

Some example data:

28/36 (Conventional)

  • 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
