the general formula is:
\n" ); document.write( "f = p * (1 + r) ^ n\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f is the future value
\n" ); document.write( "p is the present value
\n" ); document.write( "r is the interest rate per time period.
\n" ); document.write( "n is the number of time periods.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if the time period is in months, then the interest rate per time period is per month and the number of time periods is months.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "to find the present value, do the following:
\n" ); document.write( "start with f = p * (1 + r) ^ n
\n" ); document.write( "solve for p to get:
\n" ); document.write( "p = f / ((1 + r) ^ n)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if the rate per time period is given in percent per year, and the time periods is in months, then do the following:
\n" ); document.write( "r% per year = 7
\n" ); document.write( "divide that by 100 to get r per year = .07
\n" ); document.write( "divide that by 12 to get r per month = .07/12.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if the number of time periods is given in number of years, and the number of time periods needs to be in months, then do the following:
\n" ); document.write( "2 years and 11 months is equal to 24 months and 11 months which is equal to 35 months.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you have r = .07/12 per month and n = 35 months.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the formula of p = f / ((1 + r) ^ n) becomes:
\n" ); document.write( "p = f / ((1 + .07/12) ^ 35
\n" ); document.write( "simplify to get:
\n" ); document.write( "p = f / 1.225775232\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your present value will be the future value divided by 1.225775232.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for example, if the future value is 50,000, then the present value will be 50,000 / 1.225775232 = 40790.51256\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
