Will Investing $100 a Month Really Make a Difference in Your Net Worth?

Finding extra money to put into a brokerage account and invest can be really challenging -- especially if you have pressing expenses to take care of today.

It may seem really intimidating to try to transfer a ton of money out of your checking account to a brokerage firm to buy stocks. But what if you don't have to invest a fortune? If you invest just $100 a month, will that contribution really make a big difference in your net worth in the end?

How $100 a month can help make you wealthy

Investing just $100 a month can actually do a whole lot to help you grow rich over time. In fact, the table below shows how much your $100 monthly investment could turn into over time, assuming you earn a 10% average annual return.

That's a substantial amount of money to end up with, especially given that the median 401(k) balance for individuals ages 65 or over is just $87,725. You could end up with well over double what the typical American has saved for retirement, just from your $100 a month investment alone.

How investing $100 a month helps your wealth grow

A $100 monthly investment doesn't seem like a lot, but when you put this money into the market, it earns returns. If you earn 10%, in a year, your $100 initial investment would be worth $110.00. Next year, you would earn 10% not on $100, but instead on $110, so you'd end up with $121.00. This happens with each investment that you make and with each year that passes, and it has a snowball effect.

The more you're able to invest and the more time you have for compound growth to work, the more powerful the impact is. But even if you don't have more than $100 a month to invest right now, you're better off getting the money into the stock market and getting it working for you so your snowball can start to build.

If you're not sure where to come up with an extra $100 a month, some possible options for you could include:

• Do a few hours of overtime or extra work. If you can earn $15 an hour, you'd only need to work for about seven hours during the course of the entire month to make $100 extra to invest. Many people can find seven hours.
• Go through your budget carefully. You can probably find one or more expenses to cut that add up to $100. Switching to a cheaper cellphone plan, canceling a streaming service you don't use much, and giving up one meal out would probably get you there.

Over time, if you can increase the amount you invest, that would be ideal as you can build even more wealth. But you don't have to worry about that when you're just getting started. Just begin with that first $100. As you see how your money grows, you may get excited about investing and find new ways to increase your contributions -- and thus the power of compound growth in your wealth-building efforts.
