Compounder 2.0

The Compounder is a useful tool for quickly calculating compound interest. But what exactly is compound interest? It refers to the interest gained not only on the initial principal amount, but also on the accumulated interest from previous periods of a deposit or loan.

Let's illustrate this concept with an example. Imagine you have $1000 in your savings account, and each month you contribute an additional $500 at an annual interest rate of 11%. Now, after 40 years, can you guess how much your account will be worth? The astonishing answer is $4.38 million! So even with a modest monthly contribution of $500 (which is equivalent to the average car payment in America) and an interest rate of just 11% (which happens to be the same rate that the S&P 500 has averaged over the past 90 years), you have the potential to become a millionaire. No need to be a big-time Wall Street broker to achieve financial success.
