What is Compound Interest? The “Eighth Wonder of the World”
Albert Einstein famously called compound interest the eighth wonder of the world. But what does it mean? In simple terms, compound interest is the interest you earn on both your original money and on the interest you constantly accumulate.
Think of it as a snowball effect for your finances:
-
Simple Interest: You earn interest only on your initial deposit.
-
Compound Interest: You earn interest on your initial deposit and on the interest that keeps getting added to it.

Key Factors That Drive Your Investment Growth
Our compound interest calculator works by factoring in the core principles of wealth building. Understanding these will help you use the tool more effectively.
The Interest Rate You Earn
The annual percentage yield (APY) your investment earns is a major growth driver. Even a 1% difference can lead to a significantly larger sum over 20 or 30 years. Our calculator makes this impact clear.
The Power of Your Time Horizon
Time is the most critical ingredient in compound interest. The longer your money remains invested, the more cycles of compounding it can go through, accelerating your growth exponentially.
The Frequency of Compounding
How often is interest calculated and added? Common compound frequencies are annual, quarterly, monthly, or daily. The more frequent the compounding, the faster your balance grows. Our calculator typically uses annual compounding for standard projections.
A Real-World Example of Compound Interest
Let’s look at two friends, Alex and Taylor, to see the power of starting early.
-
Alex: Starts investing $200 a month at age 25. She stops at age 35, having invested $24,000. With a 7% annual return, her money grows to over $338,000 by age 65.
-
Taylor: Starts investing $200 a month at age 35 and continues until age 65, investing $72,000. With the same 7% return, Taylor’s investment grows to about $244,000.
Despite investing less money, Alex ends up with more because her money had more time to compound. Our compound interest calculator can show you your own “Alex vs. Taylor” scenario.
