# How to Read a Loan Amortization Factor Table

A common real estate math problem you may encounter on your real estate licensing exam will be to calculate a buyer’s monthly mortgage payment based on the amount and terms of the loan.  While calculating the exact monthly mortgage payment is a very complex math problem (i.e., leave it to your buyer’s lender to do the actual calculation), you can provide a ballpark estimate of what a person’s mortgage payment will be using a loan amortization factor table.

A loan amortization factor helps to estimate a buyer’s monthly mortgage payment.  EZ Real Estate Math has a sample loan amortization factor table that you can use for real estate math problems practice.  First, we need to know the terms of the loan (i.e., the length of the loan and the interest rate) in order to look up the amortization factor.  Once we have the amortization factor, we multiply it by the loan amount (calculated in thousands).  This will give us the estimated monthly mortgage payment.  Note that this only include PI (Principal and Interest) and does NOT include taxes and insurance.
