Debt/Income Ratio

Lenders use a ratio called "debt to income" to determine your maximum monthly payment after you've paid your other monthly debts.


About the qualifying ratio

Most underwriting for conventional mortgage loans needs a qualifying ratio of 28/36. An FHA loan will usually allow for a higher debt load, reflected in a higher (29/41) ratio.

The first number is the percentage of your gross monthly income that can be spent on housing costs. This ratio is figured on your total payment, including hazard insurance, HOA dues, Private Mortgage Insurance - everything that constitutes the full payment.

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

For example:

28/36 (Conventional)

  • Gross monthly income of $6,500 x .28 = $1,820 can be applied to housing
  • Gross monthly income of $6,500 x .36 = $2,340 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $6,500 x .29 = $1,885 can be applied to housing
  • Gross monthly income of $6,500 x .41 = $2,665 can be applied to recurring debt plus housing expenses
