Algebra.Com's Answer #686725 by Theo(13342) You can put this solution on YOUR website! you will be withdrawing 200 per month for 20 years.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "your annuity is earning you 2% per year compounded monthly.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you are withdrawing the money at the end of each month.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the following online calculator shows you how to do it.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the calculator can be found at http://arachnoid.com/finance/\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you would enter: \n" ); document.write( "present value = 0 \n" ); document.write( "future value = 0 \n" ); document.write( "paymnt = 200 \n" ); document.write( "interest rate percent = 2/12 = .1666667 per month \n" ); document.write( "number of months = 12 * 20 = 240 \n" ); document.write( "you would select payment at end of time period. \n" ); document.write( "you would click on pv and you would get pv = 39,534.79 as shown in the following picture. \n" ); document.write( "disregard the sign. \n" ); document.write( "it has to do with cash flows in or out. \n" ); document.write( "the pv is a cash flow out because you take your money and put it into the annuity fund. \n" ); document.write( "the payment is positive because you are receiving money from the annuity fund.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \r\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "a key point is that you need to determine the interest rate per time period and the number time periods.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "your time periods are in month because the payments are monthly and the interest rate compounding is monthly.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you take the annual percentage rate and divide it by 12 to get the interest rate percent per month.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you take the number of year and multiply them by 12 to get the number of months.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the calculator does the rest.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "there are formulas involved so that you can do the work manually by using the formula.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "they can be found here:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "https://www.algebra.com/algebra/homework/Finance/THEO-2016-04-29.lesson#notes\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the formula you would be looking for would be:\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( "\n" ); document.write( "when you are using the formulas, you need the interest rate and not the interest rate percent.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2% interest rate percent is equal to .02 interest rate.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( ".166666667 interest rate percent is equal to .00166666667\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
