Ratio of Debt-to-Income

The debt to income ratio is a tool lenders use to determine how much of your income can be used for your monthly mortgage payment after all your other monthly debts have been fulfilled.

How to figure your qualifying ratio

For the most part, underwriting for conventional mortgage loans 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 in a qualifying ratio is the maximum amount (as a percentage) of your gross monthly income that can be applied to housing costs (this includes loan principal and interest, private mortgage insurance, hazard insurance, property tax, and homeowners' association dues).

The second number is what percent of your gross income every month that should be applied to housing costs and recurring debt together. Recurring debt includes payments on credit cards, auto loans, child support, etcetera.

Some example data:

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
