You have to take interest compounding into account.
\n" ); document.write( "Every year, you make interest to add to your sum and then in the following year, you get interst on the new sum, and so on.
\n" ); document.write( "The formula is,
\n" ); document.write( "\"FV=P%281%2BR%29%5ET\"
\n" ); document.write( "where FV is the future value, P is the current investement, R is the rate of return, and T is the number of time periods.
\n" ); document.write( "FV=$2,000,000
\n" ); document.write( "R=4.5%
\n" ); document.write( "T=45 years
\n" ); document.write( "\"P=FV%2F%281%2BR%29%5ET\"
\n" ); document.write( "\"P=2000000%2F%281%2B0.045%29%5E45\"
\n" ); document.write( "\"P=2000000%2F7.2482484\"
\n" ); document.write( "\"P=275928.73\"
\n" ); document.write( "To reach her goal in 45 years, she should invest $275,928.73.
\n" ); document.write( "
\n" );
