Debt to Income - Back End - Front End ratios explained

by: Leslie Collins - 3/2006
Lenders are mainly concerned with a potential borrowers willingness and ability to repay a mortgage loan. There is no guessing - your loan will be granted or NOT based on your credit history and these three ratios: debt-to-income ratio, front-end ratio and back-end ratio. By going through the credit verification process, lenders can easily see a potential borrowers willingness to repay loans. That is, do they pay their bills on time? How many times have they been late? etc… For lenders to determine the ability of a potential borrower to repay their mortgage note, debt to Income ratios are used - "Front end and back end ratios" as they are called in the mortgage world. These ratios are the key to determining how much "house payment " a borrower can realistically handle on a month-to-month basis. Debt to Income Ratios simply compares all of a potential borrowers monthly payment obligation against gross monthly income.

Debt To Income Ratio

What is the simple formula?:
anount owed/amount you earn=debt to income ratio

Front End Ratio

This ratio will determine your maximum housing expense only, that is, your maximum mortgage payment consisting of principal, interest, tax and insurance. Typically lenders do not want this to exceed 28% of your gross monthly income.
More detail: front end ratio
FRONT END RATIO: Annual salary $40,000/12(months) = $3,333 x 28% = $933 So in this example, the borrowers maximum house payment per month would be $933.

Back End Ratio

This ratio is how much of your income can go toward all monthly obligations. That is PITI, car payments, revolving credit card debt, any monthly medical bills etc… Typically the maximum is 36%. BACK END RATIO: Annual salary $40,000/12(months) = $3,333 x 36% = $1200
