document.write( "\r\n" );
document.write( "\r\n" );
document.write( "where  FV is the future value of the account;  P is the annual payment (deposit); r is the annual percentage rate presented as a decimal; \r\n" );
document.write( "n is the number of deposits (= the number of years, in this case).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Under the given conditions, P = 2000;  r = 0.02;  n = 30.  So, according to the formula (1), you get at the end of the 20-th year\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    FV = \"2000%2A%28%28%281%2B0.02%29%5E30-1%29%2F0.02%29\" = $81,136.16.\r\n" );

document.write( "Note that you deposit only  30*$2000 = $60,000.  The rest is what the account earns/accumulates in 30 years.\r\n" );
