Credit cards don't have to be your enemy; in fact a well-chosen credit card can help maintain your financial health. Many people use their credit card to purchase goods they would otherwise not be able to afford. That is not the scenario we will be discussing here. The scenario I propose is one where you use your card for purchases that are part of your normal monthly expenses. This does two things. First it helps build your credit and second, with the right credit card, you can earn rewards to help ease the burden of anything from travel to receiving cash back for your purchases which you can apply as you wish. However, and this is a big however, this will only benefit you if you limit your charges to those you can pay off at the end of your billing cycle. If you can’t pay off your balance in full at the end of your billing cycle your accrue interest which will outweigh the benefits you gain from using the card. If you can commit to using a credit card in this manner you’ll improve your credit and gain some additional rewards which can help to offset expenses in other aspects of your life. Also many cards offer buyer protections on purchases and travel as well as fraud protection. A credit card doesn’t have to be your enemy if you are smart in the way you use it.
