Debt/Income Ratio

Your debt to income ratio is a tool lenders use to determine how much money can be used for your monthly home loan payment after all your other monthly debt obligations are met.


How to figure 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) qualifying ratio.

The first number in a qualifying ratio is the maximum percentage of your gross monthly income that can go to housing costs (this includes principal and interest, private mortgage insurance, hazard insurance, taxes, and homeowners' association dues).

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

For example:

28/36 (Conventional)

  • Gross monthly income of $8,000 x .28 = $2,240 can be applied to housing
  • Gross monthly income of $8,000 x .36 = $2,280 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $8,000 x .29 = $2,320 can be applied to housing
  • Gross monthly income of $8,000 x .41 = $3,280 can be applied to recurring debt plus housing expenses
