Credit Card Balance Transfer Calculator – NerdWallet

If you’re carrying debt on a credit card that charges typical credit card interest rates, you may be paying hundreds or even thousands of dollars a year in interest. Moving that debt to a balance transfer credit card with a 0% introductory APR period could reduce your interest costs to zero. That not only can save you money, but also can allow you to get out of debt more quickly, since every dollar you pay will go toward eliminating your balance rather than paying interest.

Our credit card balance transfer calculator can give you a sense of how much money you could save by doing a balance transfer. Tell us how much debt you’re carrying, the interest rate on that debt, and a couple of details about the balance transfer credit card you’re looking at, and we’ll estimate your potential savings.

The results you get from the credit card balance transfer calculator are an estimate of how much you could save if you moved your debt to a card with a 0% offer for balance transfers, compared with what you’d pay if you left the debt where it is. The results are based on two assumptions:

1. You’d pay off the debt within the 0% intro APR period on the balance transfer card.

Say the card you’re looking at offers 18 months of 0%. Our balance transfer calculator uses this as the time frame for estimating costs. In other words, you’ll either:

• Leave the debt on your current card and pay it off over 18 months, or

• Move it to the 0% card and pay it off over 18 months.

The calculated savings is the difference between these two.

2. You’d pay off the debt with equal payments over that period.

When you’re paying off debt on a card that’s charging you interest, your repayment schedule has a huge effect on the total amount of interest you pay. The more you pay each month, the less you’ll ultimately be charged in interest and the faster you’ll eliminate the debt. For example, say you’re starting with $3,000 in debt on a card that charges 16% interest:

There are countless ways you could choose to pay down your debt. You could pay an equal amount each month (the scenarios in the chart above), or you could pay a variable amount based on what you have available. You could pay once a month or multiple times a month. You could even just pay the “minimum amount due” shown on your statement, which will keep your account in good standing but can also keep you in debt for years.

No calculator can account for every single potential payment option. Our balance transfer calculator, therefore, assumes that your payment will be the same every month and that it will be the exact amount necessary to pay off the debt within the time frame.

To give you a better sense of the cost of carrying credit card debt without doing a balance transfer, we’ve created a second calculator that tells you exactly how much you would need to pay every month to eliminate your debt within a given time frame.

This isn’t as simple as dividing your debt by the number of months in the repayment period. If you have $1,000 in debt, for instance, paying $100 a month for 10 months won’t get you in the clear, because you’ll be charged interest. At 16% interest, you’d have to pay $107.48 a month to completely eliminate the debt in 10 months.

Tell us how much debt you have, the interest rate on that debt and how many months you’d need to pay it off, and we’ll tell you your required monthly payment, the total amount of your payments over your time frame and the total amount you’d pay in interest.

A balance transfer provides the answer to a common question: “Can I use one credit card to pay off another?” When you request a transfer, the bank that issued your new credit card sends a payment on your old card and then adds that amount to the balance on the new card, along with the balance transfer fee. You can sometimes request a transfer at the time you apply for the new card; you can also call the issuer after you get the card, or use a convenience check.

Balance transfer cards generally work the same way. The key differentiating factors are:

• Balance transfer fee. This fee will typically be 3% to 5% of the amount transferred, which translates to $30 to $50 per $1,000 transferred. The lower the fee, the better, but even with a fee on the high end, your interest savings might easily make up for the cost.

• Length of 0% introductory period. A good balance transfer credit card will have a 0% period of 15 months or longer. Some give you close to two years at 0%. You might not need that much time, but the longer the 0% period, the more flexibility you have.

• Card issuer. As a general rule, you can’t transfer debt between cards from the same issuer. If your current debt is on a Citi card, you can’t transfer it to another Citi card. You can’t transfer debt from one Wells Fargo card to another, and so on.

• Rewards. It’s worth thinking about what you’re going to do with your balance transfer credit card down the road, after you’ve paid off your debt. Many balance transfer cards don’t offer a very compelling reason to keep using them after the 0% period runs out — they offer no rewards, and their ongoing interest rates aren’t particularly low. However, a number of excellent rewards credit cards offer balance transfer promotions of 15 to 18 months.
