AOL has a good mortgage affordability calculator. The essential fields you may not be familiar with are the Frontend Ratio and the Backend Ratio. The lowest ratio of the two determines the maximum payment allowed by the lender. In California, the higher frontend and backend ratios are usually allowed. Your credit score also contributes to the allowable ratios.
The FrontEnd Ratio is defined as a ratio that indicates what portion of a borrower's income that is used to make mortgage payments. It is calculated as a borrower's monthly housing expenses divided by his or her monthly gross income and is expressed as a percentage. Monthly gross income is simply annual income divided by 12 (months). Lenders use the frontend ratio in conjunction with the backend ratio to approve mortgages. The appropriate equation is shown below:
For example, if your annual income is $60,000, your monthly income is $5,000 (60,000/12). By using frontend ratio (2836%), you can figure how much of that $5,000 you can allocate to your mortgage payments. If the required frontend ratio is 33%, you can allocate $1,650 (5,000 x 0.33). Thus, if your PITI is $1,550 or less, you would be approved.
Typical monthly housing expenses include the mortgage principal, interest, taxes and insurance payments known as PITI.
The BackEnd Ratio or debt to income ratio is defined as a ratio that indicates what portion of a borrower's income that is used to pay all of his or her debts. Total monthly debt includes expenses such as mortgage payments (made up of PITI), creditcard payments, child support and other loan payments. Lenders use this ratio in conjunction with the frontend ratio to approve mortgages. The appropriate equation is shown below:
For example, if your monthly income is $5,000 ($60,000/12) and your total monthly debt payments are $2,000, your backend ratio is 0.40 or 40%. Generally, lenders like to see a backend ratio that does not exceed 40%; however, there are lenders who make exceptions for ratios of up to 50% if you have good credit. Some lenders consider only this ratio when approving mortgages, as opposed to using it in conjunction with the frontend ratio.
