Payment tables for monthly mortgage payments allows lenders to determine monthly principal and interest payments on a fixed interest rate mortgage, according to HSH.com. The table has three columns. One displays the interest rates, and the other two show the monthly payment and total paid per $1,000 of the loan.
Additional trios of columns can be added to the table to show the number for different types of loan term periods, explains HSH.com. To figure out true monthly payment amounts and total amounts paid on loans, lenders have to multiply the monthly payment and "total amount" numbers on the table by the number of $1,000 increments on the full loan. So for a loan of $50,000, the numbers on the table are multiplied by 50.
