Debt Ratios for Home Lending

Your ratio of debt to income is a formula lenders use to calculate how much money can be used for a monthly mortgage payment after all your other monthly debt obligations are fulfilled.

About the qualifying ratio

Most underwriting for conventional loans requires a qualifying ratio of 28/36. An FHA loan will usually allow for a higher debt load, reflected in a higher (29/41) ratio.

In these ratios, the first number is the percentage of your gross monthly income that can go toward housing. This ratio is figured on your total payment, including homeowners' insurance, homeowners' dues, PMI - everything that constitutes the payment.

The second number in the ratio is the maximum percentage of your gross monthly income which can be applied to housing expenses and recurring debt together. Recurring debt includes payments on credit cards, auto/boat loans, child support, and the like.

Examples:

28/36 (Conventional)

  • Gross monthly income of $2,700 x .28 = $756 can be applied to housing
  • Gross monthly income of $2,700 x .36 = $972 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $2,700 x .29 = $783 can be applied to housing
  • Gross monthly income of $2,700 x .41 = $1,107 can be applied to recurring debt plus housing expenses
