The Power of Time
Why compound interest matters
Albert Einstein reportedly called compound interest "the eighth wonder of the world," adding that "he who understands it, earns it; he who doesn't, pays it."
Unlike simple interest, which only earns returns on your initial investment, compound interest earns returns on your returns. This creates exponential growth that accelerates dramatically over time.
The key variables are time, rate, and consistency. Starting early - even with smaller amounts - often outperforms starting late with larger sums. This is why financial advisors emphasize beginning your investment journey as soon as possible.
