use of a financial calculator gives you the answer to this.
\n" ); document.write( "you would first take the future value of an annuity for 4 years.
\n" ); document.write( "the future value becomes your present value for the next 29 years where you take the future value of a present value, using the same calculator.
\n" ); document.write( "one such calculator is the TI-BA-II Business Analyst, made by texas instruments.
\n" ); document.write( "for the first part, you make the following inputs.
\n" ); document.write( "present value = 0
\n" ); document.write( "future value = 0
\n" ); document.write( "interest rate percent per year = 6% divided by 12 = .5% per month.
\n" ); document.write( "number of years = 4 multiplied by 12 = 48 months.
\n" ); document.write( "payments are made at the end of each month.
\n" ); document.write( "you have the calculator compute the future value.
\n" ); document.write( "it is equal to 7,573.69651.
\n" ); document.write( "that becomes the present value for the next round of financial calculations.
\n" ); document.write( "your inputs to the calculator becomes:
\n" ); document.write( "present value = 7,573.69651.
\n" ); document.write( "future value = 0
\n" ); document.write( "interest rate per month = .5%
\n" ); document.write( "number of months = 29 years * 12 = 348
\n" ); document.write( "you have the calculator compute the future value.
\n" ); document.write( "it is equal to 42,963.27602
\n" ); document.write( "i did the year by year calculations in excel.
\n" ); document.write( "the results are the same and are shown below.\r
