How Compound Interest Works

Compound interest is the interest calculated on the initial principal, which also includes all of the accumulated interest from previous periods on a deposit or loan.

Think of it as "interest on interest." Unlike simple interest, which only grows based on your original deposit, compound interest grows faster because your interest earns its own interest. Over long periods, this creates an exponential curve that can turn small monthly contributions into significant wealth.
