The Power of Compound Interest
Albert Einstein reportedly called compound interest the "eighth wonder of the world." Your money earns returns, and those returns also earn returns — creating exponential growth over time.
A = P(1 + r/n)^(nt)
A = Final amount, P = Principal, r = Annual rate,
n = Compounds/year, t = Time in years
A = Final amount, P = Principal, r = Annual rate,
n = Compounds/year, t = Time in years
Why Time is Your Most Valuable Asset
Starting early makes a massive difference. Investing $200/month from age 25 at 8% leaves you with roughly 2× more than starting at 35, even with the same contribution amount. Start today.
