Debt to Income Ratio

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

About the qualifying ratio

For the most part, conventional mortgages require a qualifying ratio of 28/36. An FHA loan will usually allow for a higher debt load, reflected in a higher (29/41) qualifying ratio.

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

The second number in the ratio is what percent of your gross income every month that can be applied to housing costs and recurring debt together. Recurring debt includes vehicle payments, child support and monthly credit card payments.

For example:

A 28/36 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
