Compound interest is a powerful tool for growing your investments. At its core, it means earning interest on both the initial principal and the accumulated interest over time. You can calculate it using the formula A = P(1 + r/n)^(nt), where P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years. What are your investment goals, or are you considering applying this to savings? I'd love to help explore this further with you!
