Understanding compound interest and how it can transform your savings.
When it comes to building financial security, compound interest can be a game changer. It's a concept often heard, but not always fully understood. Simply put, compound interest allows your money to grow exponentially over time, as you earn interest on both the original amount (the principal) and the accumulated interest. Let’s dive into how it works and why it’s never too late to incorporate compound interest into your savings strategy.
What exactly is compound interest?
Compound interest allows you to invest a sum of money today that will grow into a much larger amount down the road. You earn interest not only on your original principal but also on the interest that accumulates over time. A certificate of deposit is one example of a savings option that typically pays compound interest. Unlike simple interest, which is calculated only on the principal, compound interest grows your savings faster by leveraging the power of reinvestment.
“The concept of compound interest, or ‘interest on interest’, is when accumulated interest is reinvested in the principal with future interest calculated on the new principal amount. The compounding effect exponentially increases savings over time,” says Paul Vanden Heuvel, director of consumer product/pricing and strategic market analytics at Commerce Bank. “Unlike simple interest which is calculated only on the principal, compound interest is calculated on both the principal and the accumulated interest. This is what makes it so powerful for long-term growth.”
Seeing compound interest in action.
Let’s explore this with a practical example. Imagine you invest $1,000 at an annual interest rate of 5%, compounded annually. Below is a breakdown of how your investment would grow over 10 years:
Why it’s never too late — or too early — to start
You may think that compound is only beneficial if you start young, but that’s not entirely true. While starting early gives your money more time to grow, even later in life, compound interest can significantly boost your savings.
“Time plays an important role in compound interest” says Vanden Heuval. “So, starting your investments early, even with smaller amounts, gives your money more time to grow and for the interest to compound.
For example:
- In your 20s and 30s: You have the advantage of time. Consistently contributing to a savings or retirement account can result in significant growth by retirement.
- In your 40s and 50s: Redirecting discretionary income into high-interest savings or investments can still yield meaningful returns.
- In your 60s and beyond: Even short-term compounding, like reinvesting dividends, can enhance your financial security.
“By consistently adding to your investment, you enhance the compounding effect. Each new contribution starts earning its own interest, adding to the overall growth,” according to Vander Heuval.
