Unlike simple interest which only calculates returns on the original amount, compound interest creates exponential growth as your earnings generate their own earnings. This powerful financial tool is essential for retirement planning, comparing savings accounts, evaluating investment opportunities, and understanding the true cost of loans with compound interest charges.
