The Power of Compound Interest: Building Generational Wealth

Compound interest is earning returns on your returns - the eighth wonder of the world. Small investments grow dramatically over decades. $100/month at 8% annual return becomes $100,627 in 30 years. The first 10 years generates modest returns; the last 10 years generates majority of wealth. Time is more valuable than amount - start early even with small contributions. Reinvest dividends and interest to accelerate growth. Credit cards compound against you - 20% interest becomes catastrophic. Tax-advantaged accounts (401k, IRA, HSA) maximize compound growth. Real estate compounds through appreciation. Businesses compound through growth. Starting at 25 vs 35 dramatically affects outcomes.
