Debt-to-Income Ratio

The ratio of debt to income is a formula lenders use to determine how much money is available for your monthly mortgage payment after you have met your various other monthly debt payments.

How to figure the qualifying ratio

Typically, underwriting for conventional mortgages 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 amount (as a percentage) of gross monthly income that can be applied to housing (this includes loan principal and interest, private mortgage insurance, hazard insurance, property tax, and HOA dues).

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

Some example data:

With a 28/36 qualifying ratio

  • Gross monthly income of $3,500 x .28 = $980 can be applied to housing
  • Gross monthly income of $3,500 x .36 = $1,260 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $3,500 x .29 = $1,015 can be applied to housing
  • Gross monthly income of $3,500 x .41 = $1,435 can be applied to recurring debt plus housing expenses
