See how your money grows over time with the power of compound interest. Free and instant.
Compound interest is interest calculated on both your initial principal and the accumulated interest from previous periods. Often called the eighth wonder of the world, it causes your wealth to grow exponentially over time rather than in a straight line.
Simple interest only earns on your original principal. Compound interest earns on your principal plus all previous interest. Over long time periods, the difference is enormous. A $10,000 investment at 7% for 30 years earns $21,000 in simple interest but over $66,000 in compound interest.
