Ratio of Debt-to-Income

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

About the qualifying ratio

Typically, underwriting for conventional mortgages needs a qualifying ratio of 28/36. FHA loans are a little 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 (including loan principal and interest, private mortgage insurance, homeowner's insurance, property tax, and HOA dues).

The second number is the maximum percentage of your gross monthly income that can be spent on housing costs and recurring debt. Recurring debt includes credit card payments, auto loans, child support, etcetera.

Some example data:

With a 28/36 ratio

  • 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
