Understanding Compound Interest

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. In simpler terms, it's "interest on interest." This means that over time, your money can grow at a faster rate because you're earning interest not just on your original deposit, but also on the interest you've already earned.
