The average yearly return of the S&P 500 over the last 30 years is 10.7%, but even at a conservative return of 8%, you would have over $146,000 if you invest $100 a month for 30 years. The impressive part is that your total contributions would be $36,000, which means your money would have quadrupled in value in 30 years (note that past performance does not guarantee future success).
In short, the more money and more time you have in the market, the more likely you are to grow your investment funds.
Starting to invest with a small amount of money isn’t an issue. However, it’s important to know how much you can afford to invest, as you don’t want to harm your personal finances in the process. Blackwell urged, “as long as you aren’t using money [to invest] that you need to cover day to day expenses such as food, rent and high interest debt payments, I recommend you start investing.”
