Ratio of Debt-to-Income

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

Understanding your qualifying ratio

Typically, underwriting for conventional loans requires a qualifying ratio of 28/36. FHA loans are a little less strict, requiring a 29/41 ratio.

In these ratios, the first number is how much (by percent) of your gross monthly income that can go toward housing costs. This ratio is figured on your total payment, including homeowners' insurance, HOA dues, PMI - everything.

The second number in the ratio is the maximum percentage of your gross monthly income that should be spent on housing costs and recurring debt together. Recurring debt includes things like vehicle loans, child support and credit card payments.

Examples:

A 28/36 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
