Over the past two years, the Federal Reserve has raised interest rates substantially. Consequently, credit card annual percentage rates have followed suit. Nearly all credit cards tie their interest rates to the prime rate, which has doubled to 8% from 4% during the string of rate hikes that began in 2004. This has led to interest rates on credit cards rising by 30% or more. Since August of 2006, the Federal Reserve has kept interest rates steady, and many economists believe the next move may be a reduction in rates. However, the rate reductions have yet to begin, and credit card interest rates remain relatively high.

For those who carry balances on their credit cards, high interest rates have resulted in higher monthly bills, with many seeing their minimum payment increase substantially. Fortunately, now, more than in recent years, 0% credit cards offer a safe harbor from high rates. There are two basic types of 0% credit cards: those that offer a 0% rate on balance transfers, and those that offer a 0% on purchases. The best credit cards offer 0% interest on both. How much savings can these credit cards provide? Let’s take a look at the math.

Let’s assume you’re carrying a balance of $10,000. If you simply pay the minimum each month, you will accrue close to $2000 in interest over the course of a year, thanks to daily compounding balances (too bad savings accounts don’t pay that type of interest). With a 0% balance transfer, you can expect to save all of that money, plus, you’ll be given time to pay down that debt. When the 0% period expires, not only is there a chance your interest rate will be lower, but, if rates do not go down, you can always transfer the balance to another 0% credit card. Plus, if you make a minimum payment of $150 a month, your balance at the end of the year will be closer to $8200, rather than $12,000. That’s quite a difference.
