Investing 101 from a Financial Advisor: Compound Interest

Compound interest may seem complicated, but it's really just earning interest on the interest you've already earned. Here’s a clear and simplified way of understanding this important concept. 

Imagine you save some money, let’s say $100, which grows at 10% annually. At the end of the first year, you earn 10% interest on your initial $100, giving you $110. In the second year, you earn 10% on both your original $100 and the $10 gained in the first year. So, your $110 now earns $11, which brings your total to $121 at the end of year two.

This process continues each year, with these amounts growing each time. This is a simple hypothetical, but you get the idea.

What’s magical about compound interest is how it accelerates over time. Initially, the increases may seem small, but over the years, they can add up significantly. This is often referred to as the “snowball effect”—as the snowball rolls down the hill, it grows bigger and faster. Compound interest works similarly; your savings grow exponentially, not linearly, because you continuously earn interest on both the money you originally invested and the interest you accumulate along the way.

To visualize this, think about planting a single apple tree. In its first few years, it might only produce a small basket of apples. But as the tree grows bigger and stronger, it produces more apples each year. If you plant more trees with the apples from the first one, soon you’ll have an orchard—all starting from that single tree.

Compound interest is similar to an orchard that grows from your initial investment. It becomes more fruitful over time as long as you let the interest accumulate without withdrawing it. 

Here are some tips on taking full advantage of compound interest:

1. Start Early:

The earlier you start saving, the more powerful the effect of compound interest. Even small amounts saved earlier can surpass larger amounts saved at a later stage due to the extra time they have to grow.

2. Regular Contributions: 

Consistently add to your savings. Regular contributions can significantly increase the benefits of compound interest over time. Even small additions can make a big difference in the long run.

3. Reinvest Earnings: 

Allow your interest earnings to be reinvested rather than spending them. Reinvesting your earnings will increase the principal amount and subsequently the interest you earn in future periods.

4. Choose the Right Investment Vehicle:

Higher interest rates will compound more quickly than lower rates. Explore options like stocks, bonds, or mutual funds that might offer higher returns than traditional savings accounts.

To further this point, consider the following. An individual who begins saving for retirement at age 25, contributing $5,000 annually at an average return rate of 7%, will accumulate approximately $1.07 million by the age of 65. If someone starts saving at 35, they would only have around $510,000 by age 65. This is if they save the same amount every year. 

Bottom Line

This stark difference underlines the impact of compound interest and the critical advantage of starting early. By understanding this concept, you can maximize your financial growth and work towards a more secure financial future.
