Do I even need credit cards?
Like many things, there are pros and cons to using credit cards. The other folks on here have discussed the pros and length, so I'll just quickly summarize: Convenience of not having to carry cash. Delay paying your bills for a month with no penalty. Build your credit rating for a time when you need a big loan, like buying a house or starting a business. Provide easy access to credit for emergencies or special situations. Many credit cards provide "rewards" of various sorts that can effectively reduce the cost of what you buy. Protection against fraud. Extended warranty, often up to one year Damage warranty, covering breakage that might be explicitly excluded from normal warranty.  But there are also disadvantages: One of the advantages of credit cards -- easy access to credit -- can also be a disadvantage. If you pay with cash, then when you run out of cash, you are forced to stop buying. But when you pay with credit, you can fall into the trap of buying things that you can't afford. You tell yourself that you'll pay for it when you get that next paycheck, but by the time the paycheck arrives, you have bought more things that you can't afford. Then you have to start paying interest on your credit card purchases, so now you have less money left over to pay off the bills. Many, many people have gotten into a death spiral where they keep piling up credit card debt until they are barely able to pay the interest every month, never mind pay off the original bill. And yes, it's easy to say, "Credit cards are great as long as you use them responsibly." That may well be true. But some people have great difficulty being responsible about it. If you find that having a credit card in your pocket leads you to just not worry about how much you buy or what it costs, because, hey, you'll just put it on the credit card, then you will likely end up in serious trouble. If, on the other hand, you are just as careful about what you buy whether you are paying cash or using credit, and you never put more on the credit card than you can pay off in full when the bill arrives, then you should be fine.
