How Does Compounding Impact Investing? – Basic Finance Literacy

Compounding is a key investment strategy because it can build wealth over time. If you want to know how does compounding impact investing? Keep reading until the end. Once you understand compounding in investment, your money will start earning more money for you. 

Compounding significantly increases the amount of money you get from your investment over an extended period. The big benefit of compounding is that it lets you earn interest or gains on your investment and then reinvest them to make more money. In this article, you will understand how compounding impacts investing and what future values you can expect.

What is Compounding?

Compounding means reinvesting your profits and interest to make more money. You should understand how compounding impacts investing. For example, if you have money in a savings account, the bank gives you interest on your little amount. Compounding allows you to keep this interest in your account instead of withdrawing it. Now, you earn profit from both your initial savings and the interest earned the next time the bank pays interest. Therefore, your money will grow faster with time. 

You can think of compounding investment as a snowball rolling down a hill. It gets bigger, and as it rolls, more snow gets deposited on it. Similarly, compounding helps you to accumulate more money over time with both your initial investment and the interest received. 

Understanding Compounding

When you earn interest on both the initial amount and the interest already added to the investment, it is called compounding interest. This process is a key idea to understand how money grows over time. 

As we mentioned, compounding is an important concept in finance that can impact investing. This is why many investment strategies focus on it. For example, some businesses offer dividend reinvestment programs (DRIP). Under these programs, investors can buy more shares of company stock with their cash dividends. 

Reinvestment of dividends allows investors to acquire additional shares, which in turn generate future dividend income. This type of reinvestment and growing dividends helps investors increase their profits. Let’s break it down to understand compounding.

Simple Interest vs. Compound Interest

• Simple Interest: Only the principal amount is used to calculate the interest.

• Compound Interest: Interest is calculated on both the initial balance and the interest earned over time. 

What is the Formula Using Compound Interest?

The future value of a current asset is determined using a formula relying on compound interest. It considers the current value of the asset, the annual interest rate, how often the interest is added each year, and the total number of years. The following is the standard compounding interest formula: 

Where,

A = The future value of the investment/loan, including interest

P = The principal investment amount such as the initial deposit or loan amount

r = The annual interest rate(decimal)

n = The number of times that interest is compounded per unit

t = The time of period

Explanation of Compounding Through Examples: Let’s consider a few examples to explain how compounding works in practice.

1. Example One: Annual Compounding

If you invest $1,000 at an annual interest rate of 5% compounded annually. Your investment will grow after one year:

 After the second year, interest is calculated on the new principal ($1050): 

Thus, the amount grows not only because of the interest earned on the initial $1,000 but also because of the interest earned on the $50 earned in the first year.

1. Example 2: More Frequent Compounding

The impact of compounding becomes more pronounced with more frequent compounding periods. If the same $1,000 is compounded quarterly at the same annual rate of 5%, the future value after one year is: 

While the difference might seem small in one year, the effect becomes significant over longer periods.

The Power of Time in Compounding

Time is the most important component in optimizing the benefits of compound interest. The longer you keep your money invested, the more time your money has to earn returns on both the initial amount and the interest already earned.  Compound interest takes more time to operate, which can increase the growth of your investment substantially. 

Compounding interest allows even small, frequent donations to accumulate and grow over time. It helps to increase wealth. This result shows how important consistency and patience are to reap the benefits of compound interest. The sooner you start investing, the more beneficial the power of compounding interest will be to you.

The Power of Starting Early: A Case Study with Alice and Bob

The easiest way to demonstrate the effects of compounding on investments is with real-world examples. Let’s consider two hypothetical investors, Alice and Bobs, to understand how investment timing and the power of compound interest can significantly affect the growth of their portfolios.

The Investment Plans of Alice and Bob

• Alice: She starts investing $5,000 per year at age 25. She continues this annual investment for 10 years until she reaches age 35. After 35, she stops making new contributions but leaves her investment to grow. 

• Bob: He starts investing $5,000 per year at age 35 and continues to invest this amount annually for 30 years until he retires at age 65.

Both Alice and Bob achieve an average annual return of 7% on their investments. Let’s analyze the growth of their investment over time. 

Alice’s Investment Growth: Alice invests $5,000 per year for 10 years, totaling $50,000 in contributions. After she stops contributing, her investment continues to grow at an average annual return of 7%.

1. Initial Investment Period (Age 25-35):

• Annual Contribution: $5,000
• Annual Return:7%

Let’s calculate the value of Alice’s investment at age 35 using the future value formula for a series of annuities:

Where:

P = $5,000

r =  0.07

n =  10

At age 35, Alice’s investment grows to $69,082.21.

1. Growth period (Age 35 – 65)

After the age of 35, Alice stopped contributing but let her investment grow for another 30 years by using the compound interest formula, Alice’s investment growth is $525,194.51.

Bob’s investment Growth: Bob starts investing $5,000 per year at age 35 and continues to do so until age 65, totaling $150,000 in contributions over 30 years.

Using the future value formula for a series of annuities: 

Where:

P = $5,000

r = 0.07

n = 30

At age 65, Bob’s investment grows to $472,303.96.

Comparison of Alice’s and Bob’s investment

1. Total Contributions:

• Alice = $50,000
• Bob = $150,000

2. Value at Age 65:

• Alice = $525,194.51
• bob = $472,303.96

How Do You Maximize the Power of Compounding?

Start Early: If you invest early? Your money gets more time to grow. An initial investment of any size can yield significant returns over time.

Reinvest the Money: Reinvest your money to get maximum benefit from compound interest. It requires selecting investments that compound interest rather than paying interest each year and using a dividend reinvestment program.

Regular Contributions: You can maximize the compounding effect of your investment portfolio by making regular contributions. The dollar-cost averaging technique can reduce the effects of market volatility by consistently investing a fixed amount of money.

Choose High-Compounding Investments: Look for investments that offer compound benefits. These can include stocks that pay dividends, bonds, mutual funds, and other interest-bearing accounts.

Minimize Withdrawals: The longer you leave your investments untouched, the more you can benefit from compounding Frequent withdrawals can interrupt the compounding process and reduce potential gains.

Embracing the Power of Compounding for Long-Term Investing Success

To be successful in long-term investing, you must understand and use compounding. Here are a few important elements to assist you: 

Be Disciplined and Patient: Investing requires both discipline and patience. Be prepared to stay invested for a long time. It takes time to reap the benefits of compound interest.
