the forest yields an annual return of 60,000 for a period of 8 years.
\n" ); document.write( "at the end of the 8 year period, the forest has no further value.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the company wants to earn 6% on its initial investment and also wants to set up a sinking fund to replace the purchase price.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if money is placed in the fund at the end of each year and earns 4% compounded annually, find the yearly payment.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the present value of the investment is the present value of 60,000 annual payments at the end of each year at 6% compounded annually.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the present value is therefore equal to $372,587.63 rounded to 2 decimal places.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the amount that you have to invest initially.
\n" ); document.write( "this amount will return 60,000 per year for 8 years if it earns 6% a year on that investment.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you want to replace the purchase price at the end of the 8 year period and are making payments at 4% per year compounded annually, then you would have to put $40,436.13 into the fund at the end of each year.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can use a financial calculator to do this, or you can use manual formulas.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you are using a calculator, you would do something like the following:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "to determine the initial investment:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "present value (pv) = 0
\n" ); document.write( "future value (fv) = 0
\n" ); document.write( "number of time periods (ntp or np) = 8
\n" ); document.write( "interest rate percent per time period (r%) = 6
\n" ); document.write( "payments per time period (pmt) = 60000
\n" ); document.write( "payments are set to be made at the end of each time period.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you would then have the calculator find the present value for you by clicking on the PV button.
\n" ); document.write( "the present value will be negative because that's what you shell out initially.
\n" ); document.write( "the payments will be positive because that's what you get back at the end of each time period.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i used an online calculator to show you.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "these are your inputs:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this is the output.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "to determine how much you have to invest at the end of each year in order to replace the original purchase price:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "present value (pv) = 0
\n" ); document.write( "future value (fv) = 372587.63
\n" ); document.write( "number of time periods (ntp or np) = 8
\n" ); document.write( "interest rate percent per time period (r% or ir%) = 4
\n" ); document.write( "payments are set to be made at the end of each time period.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you would then have the calculator find the payment for you by clicking on the PMT button.
\n" ); document.write( "the future value will be positive because that's what you get back.
\n" ); document.write( "the payments will be negative because that's what you shell out at the end of each time period.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the particular formula you would use to find the initial investment is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "PRESENT VALUE OF AN ANNUITY WITH END OF TIME PERIOD PAYMENTS \r
\n" ); document.write( "\n" ); document.write( "p = (a*(1-1/(1+r)^n))/r \r
\n" ); document.write( "\n" ); document.write( "p is the present value of the annuity.
\n" ); document.write( "a is the annuity.
\n" ); document.write( "r is the interest rate per time period.
\n" ); document.write( "n is the number of time periods. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the particular formula you would use to find the annual payments is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "ANNUITY FOR A FUTURE AMOUNT WITH END OF TIME PERIOD PAYMENTS \r
\n" ); document.write( "\n" ); document.write( "a = (f*r)/((1+r)^n-1) \r
\n" ); document.write( "\n" ); document.write( "a is the annuity.
\n" ); document.write( "f is the future amount.
\n" ); document.write( "r is the interest rate per time period.
\n" ); document.write( "n is the number of time periods. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when you use these formulas:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the interest rate per time period is not the percent.
\n" ); document.write( "it is the decimal eqivalent of the percent.
\n" ); document.write( "6% would become .06
\n" ); document.write( "4% would become .04\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "also, you enter all values as positive.
\n" ); document.write( "none of this negative positive business that is used with the financial calculators.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can use your scientific calculator to solve these formulas.
\n" ); document.write( "just make sure you use the parentheses exactly as shown.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i confirmed both formulas will give you the same results that the financial calculators gave you.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "as an exercise, you can do the same confirmation yourself.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let me know if you have any difficulty getting the same results manually,or understanding what transpired.\r
