📖 How compound interest accelerates wealth creation
Albert Einstein famously called compound interest the eighth wonder of the world. Interest earned in one period itself earns interest in all subsequent periods.
Formula: Future Value = Principal × (1 + r/n)^(n*t) + PMT × [((1 + r/n)^(n*t) - 1) / (r/n)]

💡 Best practices for long-term compound investing
- Start as early as possible: Time in the market beats timing the market. Starting 10 years earlier can more than double your final retirement wealth.
- Reinvest all dividends: Do not withdraw distributions; automatically reinvest them to let the snowball effect compound continuously.
