Ratio of Debt to Income
Your debt to income ratio is a formula lenders use to calculate how much of your income can be used for a monthly home loan payment after you have met your various other monthly debt payments.
How to figure the qualifying ratio
Typically, underwriting for conventional mortgage loans requires a qualifying ratio of 28/36. FHA loans are less restrictive, requiring a 29/41 ratio.
The first number in a qualifying ratio is the maximum amount (as a percentage) of gross monthly income that can be applied to housing (including loan principal and interest, PMI, hazard insurance, property tax, and HOA dues).
The second number is what percent of your gross income every month that can be spent on housing costs and recurring debt together. Recurring debt includes things like auto/boat payments, child support and credit card payments.
A 28/36 qualifying ratio
- 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
