Earning credit card rewards is great. Getting rewarded for your everyday spending helps make purchases cheaper -- as long as you don't carry a balance on your card and get stuck paying high interest rates.

Since I know how valuable credit card rewards can be, I charge just about every purchase I can -- which means I earn a lot of rewards every month. And I've managed to more than double the value of those rewards with one simple move. Here's what it is.

How I make the absolute most of credit card rewards

To get the most value from my credit card rewards, I signed up for a cash back credit card that deposits the money directly into my investment account. That means for every dollar I spend, a small deposit is made in a brokerage account that I can use to buy investments.

I also wanted a safe, no-brainer way to make the cash grow, so I invested in S&P 500 index funds, which are funds that track the performance of 500 of the largest U.S. companies. Index funds come with low fees, and there's not much research required.

Over time, the S&P 500 has consistently produced around a 10% average annual return. Now, this doesn't mean I make 10% on my money every year. Some years, my investments underperform this expectation, and in other years, they overperform. But it does mean that over the long term, this is about what I can expect my deposited cash back to produce.

Since the money I'm investing comes from cash back rewards, it isn't reducing my take-home income in any way. That makes it really easy to just leave the account alone and let the invested funds grow. And by doing this, I've more than doubled the value of my cash back rewards over time. In fact, some of the rewards I invested a decade ago are worth more than twice the amount they were valued at when they made it into my account.

Since I'm consistently investing money each month when I get my cash back rewards, I also benefit from the fact that I sometimes get to buy my S&P 500 shares at a discounted price when the market is in a downturn. And because my cash back is spread around so many large U.S. companies, the risk of losing my rewards is minimal.

Give investing your rewards a try

Now, this approach works for me because I don't need to use my credit card rewards for other things, such as funding vacations (I have a separate savings account for that). And I like the fact that every time I'm spending, I'm doing a little bit to increase my net worth.

If you aren't counting on your cash back for other purposes, consider getting a credit card that lets you deposit that money into a brokerage account so you can also turn your rewards into a hefty sum over time.
