Debt to Income Ratio

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

How to figure your qualifying ratio

Usually, underwriting for conventional mortgage loans requires a qualifying ratio of 28/36. FHA loans are less restrictive, requiring a 29/41 ratio.

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

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

Examples:

28/36 (Conventional)

  • 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
