Debt Ratios for Home Financing

The ratio of debt to income is a tool lenders use to calculate how much money is available for a monthly home loan payment after all your other recurring debt obligations have been fulfilled.

How to figure your qualifying ratio

For the most part, conventional mortgages require a qualifying ratio of 28/36. FHA loans are less restrictive, requiring a 29/41 ratio.

For these ratios, 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 homeowners' insurance, homeowners' dues, Private Mortgage Insurance - everything.

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

For example:

With a 28/36 ratio

  • Gross monthly income of $2,700 x .28 = $756 can be applied to housing
  • Gross monthly income of $2,700 x .36 = $972 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $2,700 x .29 = $783 can be applied to housing
  • Gross monthly income of $2,700 x .41 = $1,107 can be applied to recurring debt plus housing expenses
