Debt-to-Income Ratio

Lenders use a ratio called "debt to income" to determine your maximum monthly payment after your other recurring debts are paid.

About your qualifying ratio

Usually, conventional mortgage loans require 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 gross monthly income that can go to housing costs (this includes loan principal and interest, private mortgage insurance, homeowner's insurance, property tax, and HOA dues).

The second number is what percent of your gross income every month that should be spent on housing costs and recurring debt. Recurring debt includes auto/boat payments, child support and monthly credit card payments.

For example:

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
