Frequently asked questions
What is the compound interest formula?
A = P x (1 + r/n)^(n x t), where P is principal, r is the annual rate, n is the compounding frequency per year, and t is the number of years.
Does compounding frequency matter?
Yes. More frequent compounding (monthly vs annually) produces a slightly higher maturity value for the same rate.
