The excessive frequency of compounding is generally continuous compounding where the interest is compounded immediately. The data for continuous compounding for one year is e^{APR} here e is 2.71828 that is the base of the natural logarithm. So the future value of an amount which is compounded for n years is:
FV = PV x e^{kn}
Here k is annual percentage rate and e^{kn} is the compound factor.
