Mastering Compound Interest: The Magic of 20 Years

Albert Einstein famously called compound interest the 'eighth wonder of the world'. Those who understand it, earn it; those who don't, pay it. In 2026, this principle is the foundation of every modern portfolio.

The Snowball Effect

Compound interest is interest on interest. Initial growth seems slow, but as your base grows, the interest generates its own returns. Over a 20-year period, the majority of your final wealth isn't what you contributed—it's the compounding returns stacked on top of each other.

Visualize the Growth

See how a small monthly investment can snowball into a massive fortune over 20 or 30 years.

The Cost of Delay

Waiting just 5 years to start can cost you hundreds of thousands of dollars in final returns. In 2026, with easy access to global markets, there is no excuse for delay. Start with whatever you can, but start now.
