Credit cards are an essential financial tool. When you use your card responsibly, you can build credit, finance new purchases, get out of debt and earn rewards.If you’ve decided to open a new credit card, it may seem as simple as applying, but there are a few more factors to consider to ensure you get the best card for your needs.How to get a credit cardCNBC Select has five steps to follow when you want to get a credit card:Decide why you want a credit cardCheck your credit scoreShop around for the best credit card offersRead the fine printApply for the best credit card for your needs1. Decide why you want a credit cardThe first step is to figure out the reason you want to get a credit card. To make the decision easier, answer the common questions below.Do you want to build or rebuild credit? If you’re just beginning your credit journey, or looking to repair poor credit, it can be a little more difficult to find a card that fits your needs that you’ll also qualify for. Check out secured cards or cards for building or rebuilding credit. The Discover it® Secured is on both lists as one of the best options because it gives you a timeline for upgrading to an unsecured card.Do you want to earn rewards? A rewards credit card is a great way to earn cash back, points or miles on every purchase you make. You can maximize rewards by considering cards that offer bonus rewards in specific categories, such as gas, groceries, restaurants, entertainment and travel. If you rather have a simple rewards program, consider a flat-rate cash-back card, such as the Citi® Double Cash Card.Are you in debt and paying high interest? Carrying a balance on a high interest credit card can be costly. You can transfer debt to a balance transfer credit card offering no interest for up to 21 months, such as the Citi Simplicity® Card (after 16.24% to 26.24% variable APR), or a card with no balance transfer fee, such as the Amex EveryDay® Credit Card (see rates and fees).Do you have a big purchase coming up? Many credit cards offer no interest on new purchases for over a year. The Chase Freedom Unlimited® offers no interest for the first 15 months from account opening (after 16.49% to 25.24% variable APR).Do you travel abroad? Some credit cards charge around a 3% fee on purchases made outside the U.S. If you travel abroad, a credit card with no foreign transaction fees is essential. Also, some cards waive Global Entry or TSA PreCheck application fees. The Capital One® Venture® Rewards Credit Card offers cardholders both perks.2.
