How Compound Interest Works
Compound interest occurs when earned interest is added back to the original balance, allowing future interest to be calculated on a larger amount.
Over time, this process may significantly increase savings and investment growth compared to simple interest.
The longer the investment period, the greater the potential impact of compounding.
