Stash compound interest calculator

Compounding is one of the most important terms for a beginner investor to understand. Compounding is the process where any return earned on an investment gets added to the principal amount invested. The interest rate is then applied to that new, larger principal amount. Simply put, compounding is like earning interest on interest—similar to the snowball effect.

Over time, compounding could have an exponential effect on your money. That’s why it can be important to start saving and investing as soon as possible, to let the power of compounding work to its full advantage.

Investing can be a critical part of building wealth. As time passes, inflation can eat away at the value of your saved cash—making it worth less over the years. On the other hand, the average annual return of the S&P 500 has been around 8%, historically. Even if it’s just $1 at a time, it’s important to start investing as soon as possible so you can maximize your money’s growth potential and take advantage of compound returns over the years.
