Ratio of Debt to Income

The ratio of debt to income is a tool lenders use to determine how much of your income is available for a monthly mortgage payment after you have met your various other monthly debt payments.

About your qualifying ratio

Typically, underwriting for conventional loans requires a qualifying ratio of 28/36. FHA loans are 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, homeowners' dues, Private Mortgage Insurance - everything that constitutes the full payment.

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 payments on credit cards, vehicle loans, child support, etcetera.

Some example data:

A 28/36 qualifying ratio

  • Gross monthly income of $4,500 x .28 = $1,260 can be applied to housing
  • Gross monthly income of $4,500 x .36 = $1,620 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $4,500 x .29 = $1,305 can be applied to housing
  • Gross monthly income of $4,500 x .41 = $1,845 can be applied to recurring debt plus housing expenses
