Using credit cards unwisely can lead to a mountain of debt. If you charge more than you can afford, make low monthly payments, or pay late, you might be headed for problems.
But if you learn to use your credit cards wisely, they can be convenient, help build good credit, and prove useful in emergencies.
Depending on how you use it, a credit card can be one of two things: either a high interest loan or a convenient way to make purchases.
Using a credit card as a high interest loan. If you carry a balance, a credit card is basically a very high interest loan. If you make only the minimum payment each month, you’ll be paying off the debt for years and years to come, including a huge amount of interest. (For more on understanding credit cards and their terms, see Choosing a Credit Card: What You Need to Know.)
Using a credit card for convenience. On the other hand, if you pay off the balance each month, a credit card becomes a convenient way to purchase items and services without carrying around a lot of cash. Use your credit card as a cash substitute, not as a high-interest loan.
Don't use a credit card to finance an unaffordable lifestyle. If you can't pay off the entire balance every (or almost every) month, then you’re overspending. Use these guidelines to determine what you should and shouldn't charge:
If you can’t keep your credit card spending in check, create a budget. Make each credit card purchase only within the framework of your budget. If you can't stick to your budget, then don't carry your credit card with you.
The single most important rule about wise credit card use is this: pay off the entire outstanding balance each month. If you have to carry a balance from time to time, pay off most of the balance each month. If you’re able to only make the minimum payment each month, you’re in over your head. Stop using the credit card until you pay the entire balance off. (If you are struggling with credit card and other kinds of debt, see Options for Dealing With Your Debt.)
Penalties for late payments add up. And, many credit cards jack up your interest rate if you pay late a few times, sometimes to as high as around 20-30%. Late payments also damage your credit report. (For more on credit card late fees and interest rates, see Avoiding Credit Card Traps.)
You really only need one card, or two if some vendors don't accept your main card. With one or two cards, you can keep track of purchases and make sure you pay each on time. If you have to use one card to pay off the balance of another, that’s a problem.
Using a credit card to get cash advances can be very expensive. Here's why:
Credit card issuers bombard cardholders with ads for products like credit card fraud protection plans, travel clubs, and life insurance. These are almost always overpriced or provide something you don't need. Shred the ads you receive without reading them.
Keep all credit card receipts and reconcile them with your statement each month. Review the statement as soon as you get it.
A careful review of your statement is the only way you can detect mistakes or fraudulent charges. To limit your liability, you must deal with these immediately.
