Debt Ratios for Home Financing

Your debt to income ratio is a formula lenders use to calculate how much money can be used for your monthly mortgage payment after all your other recurring debts have been fulfilled.

About your qualifying ratio

Usually, 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) ratio.

The first number is how much (by percent) of your gross monthly income that can go toward housing. This ratio is figured on your total payment, including hazard insurance, HOA dues, PMI - everything.

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

Some example data:

28/36 (Conventional)

  • 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
