if you invest 18000 at the end of each year, then the future value will be equal to 186,011.85.
\n" ); document.write( "if you invest 18000 at the beginning of each year, then the future value will be equal to 199,404.70.
\n" ); document.write( "the above results were achieved through use of the arachnoid financial calculator found at https://arachnoid.com/finance/
\n" ); document.write( "results from the use of that calculator are shown below.
\n" ); document.write( "inputs were everything except future value (fv).
\n" ); document.write( "output was future value.
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "i also used the sum of a geometric series formula of Sn = a * (1-r^n)/(1-r).
\n" ); document.write( "a is equal 18000.
\n" ); document.write( "r is equal to 1.072.
\n" ); document.write( "n is equal to 8
\n" ); document.write( "the formula becomes Sn = 18000 * (1 - 1.072^8)/(1-1.072) = 186011.85.
\n" ); document.write( "this is the same result as 18000 invested at the end of each year.
\n" ); document.write( "i would go with 186011.85 as the future value first.
\n" ); document.write( "let me know if you have any questions.\r
