The Power of Compound Interest
Compound interest is often called the "eighth wonder of the world" because it allows your money to grow exponentially over time. Unlike simple interest, compound interest earns interest on your interest.
The Formula
A = P(1 + r/n)^(nt)
Where A = Final amount, P = Principal, r = Annual rate, n = Compound frequency, t = Years
Tips for Maximizing Growth
- Start investing as early as possible - time is your greatest asset
- Make regular contributions, even small amounts add up
- Reinvest dividends and interest
- Choose investments with higher compound frequencies when possible
