Example Calculation

How does compound interest build wealth over time?

Starting with $10,000 and adding $500/month at an 8% average annual return for 30 years: Your total contributions would be $190,000 ($10K initial + $180K in monthly deposits). But with compound growth, your portfolio would grow to approximately $745,000.

Result: Compound interest generated $555,000 in earnings on top of your $190,000 in contributions — nearly 75% of the final value came from returns, not deposits. Starting 5 years later would reduce the final amount by roughly $230,000. Time in the market is the most powerful factor in wealth building.
