CI Formula: A = P(1 + r/n)^(nt). Where P = Principal, r = Annual rate (decimal), n = Compounding frequency per year, t = Time in years. Interest = A - P.
Monthly compounding gives a higher effective return than annual compounding for the same nominal rate. For example, 12% annually = 12.68% effective rate when compounded monthly.
