As has been mentioned in various of your other threads, the "n" refers to the number of compoundings per interest-rate period.

For instance, if the interest rate is quoted as being "annual", then the interest-rate period is one year. Then if the interest were compounded monthly, n would be 12, because there are twelve months in one year. If the interest were compounded quarterly, then n would be 4, because "quarter" means "one-fourth", and there are four fourths (four quarters) in one year. If the interest were compounded daily, then n would be 360, 365, 366, or 365.25, depending on how a "year" is defined (by the bank and/or contract) in terms of the number of days.

I hope this clarifies this issue for you.
