📘 What Is Compound Interest?
Compound interest is the interest you earn on both your original money and on the interest that has already been added to your account. Think of it as "interest on interest"—a powerful force that causes your wealth to grow at an accelerating rate over time.
The earlier you start, the more time your money has to compound. Even small, regular contributions can grow into substantial sums thanks to this exponential effect. Albert Einstein famously called it the "eighth wonder of the world." The key ingredients are time, rate of return, and consistency—factors you control with every input you enter above.
