What is Compound Interest?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. It's often called "interest on interest" and is one of the most powerful concepts in finance.
The formula: A = P(1 + r/n)^(nt) — where A is the final amount, P is principal, r is annual rate, n is compounding frequency, and t is time in years.
