Michael L. Niemczyk Explains the Power of Compound Interest: How to Make Your Money Work for You

Michael L. Niemczyk is a financial professional and author of the book, “Will You Run Out of Money Before You Run Out of Life?™”. He has also sat on various Advisory Boards, trained countless advisors, and has been featured on many radio programs and in magazine articles. In the following article, Michael L. Niemczyk discusses compounding interest, how it works and ways to take advantage of its benefits.

Understanding how to make your money work for you is a crucial aspect of financial planning and wealth building. One of the most powerful tools available to investors is compound interest. Albert Einstein reportedly called compound interest “the eighth wonder of the world,” and for good reason.

Michael L. Niemczyk on the Basics

Compound interest is the process by which the interest earned on an investment is reinvested to earn more interest. In other words, it’s the interest on your interest. This differs from simple interest, where you only earn interest on your initial principal. Over time, compound interest can lead to exponential growth of your investment.

How Does Compound Interest Work?

Michael L. Niemczyk says that to understand how compound interest works, it’s important to break it down with a simple example. Suppose you invest $1,000 at an annual interest rate of 5%, compounded annually.

In the first year, your initial investment of $1,000 earns 5% interest, amounting to $50. This brings your total to $1,050.

In the second year, you earn 5% interest on the new total of $1,050, yielding $52.50. Your total now becomes $1,102.50.

Moving into the third year, the 5% interest on $1,102.50 generates $55.13. Consequently, your total amount grows to $1,157.63.

This continuous cycle illustrates the power of compound interest, where each year’s earnings contribute to the principal amount, leading to accelerated growth over time.

The formula for calculating compound interest is expressed as:

A = P(1 + r/n)^(nt)
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (in decimal form)
n = the number of times that interest is compounded per unit time
t = the time the money is invested or borrowed for, in years

Factors Affecting Compound Interest

Michael L. Niemczyk explains that several factors influence how much you can earn through compound interest:

  • Principal Amount: The initial amount of money you invest or save.
  • Interest Rate: The percentage at which your money grows annually.
  • Compounding Frequency: How often the interest is added to the principal (e.g., annually, semi-annually, quarterly, monthly, or daily). The more frequently interest is compounded, the more interest you will earn.
  • Time: The duration for which you invest or save your money. The longer you let your money compound, the more it will grow.

Michael L. Niemczyk Explains the Power of Compound InterestThe Power of Time

Time is the most critical factor in the power of compound interest. The earlier you start investing, the more time your money has to grow. To illustrate this, consider two investors, Alice and Bob:

  • Alice starts investing $5,000 annually at the age of 25 and stops at 35. She invests a total of $50,000 over 10 years.
  • Bob starts investing $5,000 annually at the age of 35 and continues until he is 65. He invests a total of $150,000 over 30 years.

Assuming both Alice and Bob earn an average annual return of 7%, who will have more money at age 65?

Alice’s investment grows for 40 years, while Bob’s investment grows for 30 years. Despite investing less money, Alice’s investment benefits from an additional decade of compounding.

At age 65:

  • Alice’s investment grows to approximately $602,070.
  • Bob’s investment grows to approximately $540,741.

Alice ends up with more money even though she invested less, simply because she started earlier. This example highlights the importance of starting early to maximize the benefits of compound interest.

Application in Real Life

Michael L. Niemczyk says that to harness the power of compound interest and make your money work for you, consider the following strategies:

Start Early

The sooner you start investing, the more time your money has to grow. Even small contributions made early can lead to significant growth over time.

Invest Regularly

Consistent investments, such as monthly contributions to a savings account or investment fund, take advantage of dollar-cost averaging and compound interest. Set up automatic transfers to ensure regular investments.

Reinvest Earnings

Reinvest dividends, interest, and capital gains to take full advantage of compound interest. Many investment accounts offer automatic reinvestment options.

Choose High-Yield Investments

Invest in accounts or assets that offer higher interest rates. However, be mindful of the associated risks. Higher returns often come with higher risks.

Increase Contributions Over Time

As your income grows, increase your investment contributions. Even small increases can have a significant impact over the long term.

Retirement Accounts

Retirement accounts such as 401(k)s, IRAs, and Roth IRAs are excellent vehicles for harnessing compound interest. These accounts offer tax advantages that can enhance the compounding effect. For example:

  • Traditional 401(k) and IRA: Contributions are made pre-tax, and investments grow tax-deferred until withdrawal.
  • Roth IRA: Contributions are made post-tax, but investments grow tax-free, and qualified withdrawals are tax-free.

Michael L. Niemczyk reports that maximizing contributions to these accounts can significantly boost your retirement savings through the power of compound interest.


The power of compound interest cannot be overstated. It is a fundamental principle of investing that can significantly grow your wealth over time. By starting early, investing regularly, and choosing high-yield investments, you can harness the full potential of compound interest to make your money work for you. Whether you’re saving for retirement, a major purchase, or building a financial safety net, understanding and leveraging compound interest is key to achieving your financial goals. Start today, and let time and compound interest work their magic on your investments.
