What Is Compound Interest?
Compound interest means earning returns not only on your original savings but also on the returns you have already accumulated.
In simple terms, your money can begin earning more money.
This is why time can be such a powerful factor in long-term saving and investing.

Why Does Time Matter?
Imagine you invest $10,000 today and add $200 every month.
Assuming a constant 7% annual return, compounded monthly:
- After 10 years: approximately $54,714.
- After 20 years: approximately $145,000.
The longer investment period allows previously earned returns to generate additional returns.
This is the power of compound interest.
Three Things to Remember
Start early: More time gives compound growth a greater opportunity to work.
Save regularly: Even small monthly contributions can add up over many years.
Understand the risks: Actual investment returns fluctuate. Taxes, fees, and inflation can reduce the value of your savings.
