SUMMARY
The compounded period used by Microsoft Excel in calculating financial functions can be altered by changing the number of periods over which the function is calculated; for example, a four-year loan compounded monthly will have 48 periods (four years times 12 months). The rate should be entered as the rate for each period.

To calculate a 9 percent annual interest rate, compounded monthly, enter the monthly interest rate, which in this example is .75 percent (9 percent divided by 12 months).

As an example, when you calculate the future value of $10,000 four years from now at an annual interest rate of 9 percent, Microsoft Excel returns the following results:

  Compounded Period     Formula                      Result -    ---                      --

yearly               =FV(9%,4,,-10000)            $14,115.82 quarterly            =FV(9%/4,4*4,,-10000)        $14,276.21 monthly              =FV(9%/12,4*12,,-10000)      $14,314 daily                =FV(9%/365,4*365,,-10000)    $14,332.66
