The Power of Compound Interest
How You Can Benefit
“Money makes money. And the money that money makes, makes money.” – Benjamin Franklin
What is interest, and how is it leveraged to help people become financially healthy and possibly wealthy? Interest is defined as the cost of borrowing money or the earnings on an investment. When an individual borrows money, there is a percentage attached to be paid to the loaning party. Or when a person saves or invests, the person earns a percentage on those funds. The interest rate is the predetermined percentage paid or earned on the principal amount.
Two of the most common types of interest are simple and compound. Simple interest is computed only on the principal amount, meaning the rate remains constant over each period. Compound interest is earned on both the original principal and the accumulated interest over time. This means the rate will be higher each period. Between the two, the compounding will make you more money.
Say you invest $1,000 in a savings account that compounds interest annually at a 5% rate. After 10 years, your balance would grow to approximately $1,628.89. If that same $1,000 was placed in a simple interest account, the balance after 10 years would only be $1,500. This illustrates why compound interest is a game-changer for building wealth over time.

The Benefits of Compound Interest in Savings
“Compound interest is the eighth wonder of the world. He who understands it earns it; he who doesn’t pays it.” – Albert Einstein
By saving in an account that earns compound interest, your money can grow exponentially. Financial institutions offer various accounts designed to maximize earnings. At Champions First Credit Union, members have access to savings options that allow them to take full advantage of compound interest.

Starting early is key. The longer your money sits in a compound interest-bearing account, the greater the returns. Even small, consistent contributions over time can lead to significant financial growth. For example, saving just $100 per month in an account that earns 5% annually can grow to over $150,000 in 30 years.
How to Maximize the Power of Compound Interest
“Do not save what is left after spending but spend what is left after saving.” – Warren Buffett
Start Saving Early – The earlier you start investing or saving, the more time your money has to grow. Even if you start small, consistency is key.
Choose the Right Accounts – Not all savings accounts are created equal. Look for accounts that offer competitive interest rates and frequent compounding periods. Many credit unions provide better rates than traditional banks.
Reinvest Your Earnings – If you receive interest payouts, consider reinvesting them to take full advantage of compounding. This strategy is often used in retirement accounts, such as IRAs and 401(k)s.
Automate Your Savings – Set up automatic transfers to your savings or investment accounts. This ensures consistent contributions and prevents the temptation to spend.
Monitor Economic Trends – Keep an eye on interest rate trends and economic reports, such as those provided by the Bureau of Economic Analysis. You can stay informed by checking their latest updates. Economic conditions can influence interest rates and investment opportunities.
Example of Compound Interest
Consider twin brothers Sam and Jake. Both invest $200 per month, but Sam starts at 25 while Jake waits until 35. Sam contributes for 30 years at an 8% annual return, then stops at 55 and lets his money grow. Jake contributes the same total amount but earns 10% annually. By the time they reach 65, Sam will have accumulated $666,023, while Jake will have around $455,865. Even though Jake had a higher interest rate, Sam’s early start gave him over $210,000 more at retirement. This demonstrates that time in the market is more powerful than a higher return alone!
The Role of Compound Interest in Debt Management
Just as compound interest can work for you in savings and investments, it can also work against you in debt. Credit cards, loans, and other financial obligations that accrue compound interest can grow rapidly if not managed properly. This is why paying down high-interest debt quickly is essential to maintaining financial health. Prioritizing debt with the highest interest rates and making more than the minimum payments are ways you can reduce the total amount paid over time.
For example, if you have a credit card balance of $5,000 with an interest rate of 18%, making only the minimum payment can cost you thousands in interest over time. However, making larger payments or consolidating to a lower-interest loan can significantly reduce the overall cost.
The Long-Term Impact of Compound Interest on Retirement Planning
For those planning for retirement, compound interest plays a crucial role in ensuring financial security. By investing in retirement accounts early, individuals can build substantial wealth over time. Accounts like 401(k)s and IRAs offer tax advantages that allow savings to grow even faster. Many employers also offer contribution matches, further boosting retirement savings.
If an individual invests $500 per month into a retirement account with a 7% return starting at age 30, they could have over $1.2 million by retirement age. But if they wait until age 40 to start, their balance would be significantly lower, illustrating why time in the market is so valuable.
Understanding and leveraging compound interest is one of the most powerful financial strategies available. Whether you’re saving for a big purchase, retirement, or simply looking to grow your wealth, compound interest can work in your favor. By making smart choices—such as saving early, reinvesting earnings, and avoiding high-interest debt—you can maximize its benefits.
