Credit cards: they can help, they can hurt
Much has been made of the potential pitfalls of using credit cards; the biggest single issue being the interest rate if the balances are not paid in full every month. Credit cards also can bite you with late fees, over limit fees, and annual fees (although it’s quite easy to get cards without annual fees). Many have decided to totally forego the use of credit cards, in large part due to these many pitfalls.
On the other side of the aisle, however, there are some benefits to using credit cards that can make life better for the user. Renting a car without a credit card is close to impossible. Some credit cards offer free or discounted extended warranties on items purchased with them. And of course, there’s the dozens (if not hundreds) of “reward” programs which can give you airline miles, gift certificates to Amazon.com, or actual cash. Responsible use of credit cards, which are often the first type of credit account people have, can help boost your credit score (and yes, irresponsible use of credit cards can harm it).
A disciplined spender can certainly use credit cards largely to their advantage; as long as they pay off the entire balance on time every month, they avoid the interest charges and late fees, and careful choice of cards can eliminate annual fees. I have a Pentagon Federal Credit Union Platinum Visa card that gives me a 1.25% cash discount on all purchases other than gasoline–on gas the discount is 5%, which really helps when gas is $3.50 a gallon. In a pinch, a credit card can–painfully–be an emergency fund. My Amazon.com Visa card not only gives me a certain percentage of purchases credited toward Amazon Gift Certificates, but also offers extended warranty coverage on almost all purchases, which has saved me a huge amount of money over the years. And sometimes credit cards run “balance transfer” offers where they’ll allow you to pay off the balance of another credit card by transferring the balance onto their card, sometimes with rates as low as zero percent (although often with a fee).
Some will argue that even with balances paid in full every month and no annual fee, credit cards still cost their users money, by encouraging them to buy things they wouldn’t buy if they had to pay cash. This may indeed be true; of course, the discipline of the individual spender is the key in determining what gets bought and what doesn’t.
So are credit cards more likely to hurt you or help you financially? I think that like a sharp knife, a credit card is a tool: used with skill and wisdom, credit cards can reward you in many ways; used carelessly, it can certainly do a lot of damage to your financial situation.
