Debt Ratios for Home Lending

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

About your qualifying ratio

For the most part, conventional mortgage loans 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 amount (as a percentage) of your gross monthly income that can be applied to housing (this includes loan principal and interest, private mortgage insurance, hazard insurance, property taxes, and homeowners' association dues).

The second number is the maximum percentage of your gross monthly income that should be applied to housing expenses and recurring debt. Recurring debt includes payments on credit cards, auto/boat loans, child support, etcetera.

For example:

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
