Ratio of Debt to Income
The debt to income ratio is a tool lenders use to calculate how much money is available for your monthly home loan payment after you meet your other monthly debt payments.
Understanding the qualifying ratio
Typically, conventional mortgages need a qualifying ratio of 28/36. FHA loans are less strict, requiring a 29/41 ratio.
For these ratios, the first number is how much (by percent) of your gross monthly income that can be spent on housing costs. This ratio is figured on your total payment, including homeowners' insurance, HOA dues, Private Mortgage Insurance - everything.
The second number in the ratio is what percent of your gross income every month which can be spent on housing costs and recurring debt together. Recurring debt includes payments on credit cards, auto payments, child support, etcetera.
Some example data:
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
