\n" ); document.write( "You have $400,000 saved for retirement. Your account earns 8% interest.
\n" ); document.write( "How much will you be able to pull out each month, if you want to be able to take withdrawals for 25 years?
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        This problem is posed incorrectly. To be correct, the problem must to point WHEN the withdrawals
\n" ); document.write( "        are made, at the end or at the beginning of each compounding period (which is month).
\n" ); document.write( "        Usually/traditionally, in such problems it is assumed that the withdrawals are made at the BEGINNING
\n" ); document.write( "        of each month for living. So I will follow this hypothesis. But I should notice, with the DEEP SORROW,
\n" ); document.write( "        that the creators of this problems do not know the basics of the subject and are not able to pose the problem in a right way.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Use the general formula  A = \"W%2Ap%2A%28%281-p%5E%28-n%29%29%2Fr%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Here A is the initial amount at the account; W is the monthly withdrawn value at the beginning of each month; \r\n" );
document.write( "r is the nominal monthly percentage r = 0.08/12 presented as a decimal;  \r\n" );
document.write( "p = 1 + r  and n is the number of withdrawing periods (months, in this case).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In this problem,  W is the unknown;  the monthly rate is  r = 0.08/12,  \r\n" );
document.write( "p = 1 + 0.08/12, the number of payment periods (= the number of months) is n = 25*12 = 300.  So\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "          400000 = \"W%2A%281%2B0.08%2F12%29%2A%28%281-%281%2B0.08%2F12%29%5E%28-300%29%29%2F%280.08%2F12%29%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The factor  \"%281%2B0.08%2F12%29%2A%28%281-%281%2B0.08%2F12%29%5E%28-300%29%29%2F%280.08%2F12%29%29\" is equal to 130.4282861;  therefore\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "           W = \"400000%2F130.4282861\" = 3066.82 dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus you will be able to withdraw $3066.82 every month (at the beginning of each month) during 25 years.\r\n" );
