Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. It makes your money grow faster than simple interest because you earn "interest on interest."
What is the compound interest formula?
A = P(1 + r/n)^(nt), where A = future value, P = principal, r = annual rate (decimal), n = compounding frequency per year, t = time in years.
How often should interest be compounded?
More frequent compounding results in slightly higher returns. Daily compounding yields slightly more than monthly, which yields more than annually. However, the difference between monthly and daily compounding is minimal.
