Let’s say you invest $1,000 in an index fund with an average annual return of 10%. That investment could grow to about $1,100 after just one year. But if you didn’t touch it for 25 years and let it continue compounding, it would grow to more than $12,000 at that rate, even with no additional contributions.
If you continued to invest an additional $100 a month in that fund over those 25 years and got the same return rate, your investments could grow to more than $145,000.
Another way to think about the potential growth investment can bring is by using the Rule of 72.
“It’s basically the length of time it takes for an investment to double, and it’s a pretty simple calculation,” says Brian Ford, Truist head of financial wellness. “You’re dividing 72 by your rate of return—let’s say 8%, which is around an average annual stock market gain. For example, you simply take 72 divided by eight, which equals nine, so your $1,000 is going to double in nine years.”
So don’t underestimate the power of a $1,000 investment!
