tract of land equals 1 million dollars.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this is paid with a 25 year mortgage at 4.2% interest per year compounded monthly.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i used the texas instruments BA-II financial calculator.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "first inputs were:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "present value = 1000000
\n" ); document.write( "future value = 0
\n" ); document.write( "number of time periods = 25 years * 12 months per year = 300 months.
\n" ); document.write( "interest rate per time period = 4.2% per year / 12 = .35% per month.
\n" ); document.write( "payments made at the end of each month.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i tell the calculator to compute the payment amount.
\n" ); document.write( "the calculator tells me that the monthly payment needs to be $5389.423179.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i change the number of time periods to 20 years * 12 months per year = 240 months.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i tell the calculator to compute the present value.
\n" ); document.write( "the calculator tells me that the present value is equal to $874,096.4935.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "what happened?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i first had the calculator tell me the payment amount for the 25 year loan.
\n" ); document.write( "once i had the payment amount, i then had the calculator tell me the present value of that payment amount for 20 years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the original number of months was 300.
\n" ); document.write( "that set the payment amount.
\n" ); document.write( "once that was set, the revised months was 240.
\n" ); document.write( "300 minus 240 = 60 months = 5 years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the present value of the same payments for the last 240 months is the remaining balance after the first 60 months are over.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this can be seen in more detail using excel, as shown below.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can see from the excel printout that the remaining balance at the end of 60 months is $874,096.49.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that compares favorably to what i got using the TI-BA-II calculator, which showed me that the present value of the remaining 20 years on the loan was $874,096.4935.\r
