Balance transfers are the best way to save money if you have good or excellent credit history, but carry a balance on your card. With a high interest rate, it can take decades to pay off your debt, but with a no-fee 0% interest balance transfer offer from a reputable bank, you'll pay off your balance much faster.
Keep in mind that you cannot use a balance transfer offer from the same bank that issued the card you want to transfer a balance from. Look for offers from a different card issuer. If you have a large balance - higher than $10,000, for example - you probably won't be able to put the entire balance on one card. Apply for more than one card so you can spread the balance over several cards and maximize your savings.
For people stuck paying high interest rates on their credit cards, balance transfer credit cards are a great way to save money. With a 0% APR balance transfer credit card, you can move your old balance to a card that carries better terms and lower interest rates. But once you make even one late payment, not only will your 0% rate end, you may get slapped with a penalty APR.
With a balance transfer, you are literally moving your balance from one card to another - allowing you to enjoy a lower interest rate while you pay off a balance from the holidays, a large purchase, or a high-interest card. You might want to do this when an introductory period on one card ends, in order to extend the benefits of low interest.
You also may want to consolidate debt by moving multiple credit card balances to one card, so you have fewer bills to pay each month. If your credit limit allows you to accommodate your combined balances, it will make your life simpler and your credit card balance easier to pay off.
