Albert Einstein reportedly called compound interest the "eighth wonder of the world." It is the process where the interest you earn on an investment also starts earning interest, causing your wealth to grow exponentially over time. Our Compound Interest Calculator helps you visualize this growth.
Enter your initial principal amount, your expected annual interest rate, the compounding frequency (daily, monthly, annually), and how much you plan to contribute monthly. The tool will generate a clear breakdown of your future balance.
Simple interest is calculated only on the principal amount. Compound interest is calculated on the principal PLUS all accumulated interest from previous periods.
