What a balance transfer card does and who it helps

A balance transfer card lets you move debt from one credit card to another, usually at a much lower interest rate for a set period. The new card charges 0% interest for anywhere from 6 to 21 months, depending on the card. During that time, you pay down the balance without interest piling up.

This works best if you have existing credit card debt at a high rate and can pay off most or all of the transferred balance before the promotional period ends. If you can't pay it off in time, the interest rate jumps to the card's regular rate, which is often 15% to 25%. The catch is that balance transfer cards usually require decent credit to get approved — typically a score of 650 or higher, though some cards go lower.

For low-income households, a balance transfer can free up money in your monthly budget by cutting your interest charges. But it only works if you stop using the old card and don't rack up new debt on the new one while you're paying down the transfer.

Key Takeaways

  • Balance transfer cards charge 0% interest for a promotional period (usually 6 to 21 months), then switch to a regular rate that can be 15% to 25%.
  • You typically pay a one-time transfer fee of 3% to 5% of the amount you move, which gets added to your balance.
  • This strategy only saves money if you pay down the transferred balance before the promotional period ends.
  • You need a credit score of around 650 or higher to get approved, and approval is not may provide.
  • If you can't stop using credit while paying down the transfer, this approach will likely make your debt worse, not better.

How the transfer fee works and what it really costs

When you move a balance to a new card, the card company charges a fee — usually 3% to 5% of the amount transferred. If you transfer $3,000, expect to pay $90 to $150 just to move it. That fee gets added to your new balance, so you're starting out owing more than you did before.

The math still often works in your favor if your current card charges 20% interest and the new card charges 0% for 12 months. On a $3,000 balance at 20%, you'd pay about $600 in interest over a year if you made no payments. A 4% transfer fee ($120) plus zero interest is much cheaper. But you have to actually pay down the balance during those 12 months. If you transfer $3,000 and make no payments, you'll owe $3,120 when the promotional period ends, and then interest starts accruing on the full amount.

Some cards offer 0% on transfers with no fee, but these are rare and usually go to people with excellent credit. Check the fine print before you apply — the fee and the length of the promotional period are what determine whether this saves you money.

The promotional period and what happens when it ends

The promotional period is the window of time during which you pay 0% interest. It's not permanent. After it ends — whether that's 6 months or 21 months — the card's regular interest rate kicks in on any remaining balance.

This is where the strategy can backfire. If you transfer $5,000 and the promotional period is 12 months, you need to pay down that $5,000 (plus the transfer fee) in 12 months or less. That's about $417 per month. If your budget only allows $200 per month, you'll have $2,600 left when the promotion ends, and suddenly you're paying 18% interest on $2,600. You're back where you started, except now you've also paid the transfer fee.

Before you apply, calculate what your monthly payment would need to be to clear the balance before the promotion ends. If that number is more than you can afford, a balance transfer won't help you. You'd be better off looking at a debt management plan or talking to a nonprofit credit counselor, which are free services.

Credit score requirements and approval odds

Balance transfer cards are not available to everyone. Most require a credit score of 650 or higher; some go down to 600. A few cards marketed to people rebuilding credit exist, but they offer shorter promotional periods (6 months instead of 12 to 18) and higher fees.

Your credit score is based on your payment history, how much credit you're using, the length of your credit history, and the types of credit you have. If you've missed payments, have high balances on other cards, or have recently applied for credit, your score is probably lower. Applying for a balance transfer card will trigger a hard inquiry, which temporarily lowers your score by a few points.

If your score is below 650, you can still work on paying down debt, but a balance transfer card probably won't be an option right now. Focus on making on-time payments for the next few months, and your score will start to climb. A nonprofit credit counselor can help you make a plan without costing you anything.

When a balance transfer makes sense and when it doesn't

A balance transfer makes sense if all of these are true: you have credit card debt at a high interest rate (18% or more), your credit score is 650 or higher, you can afford to pay down the transferred balance before the promotional period ends, and you can stop using credit while you pay it down.

It does not make sense if you're still adding to your credit card debt every month, if you can't afford the monthly payment needed to clear the balance in time, or if you're likely to use the new card for new purchases. New purchases on a balance transfer card usually start accruing interest right away, even during the 0% promotional period. That means you'd be paying interest on new charges while the transferred balance sits at 0%, which defeats the purpose.

If you have multiple high-interest cards, you might transfer the highest-rate balance to the new card and attack it aggressively while making minimum payments on the others. But only do this if you can afford both. Juggling multiple cards while trying to pay down debt is how people end up deeper in the hole.

Alternatives if a balance transfer card isn't an option

If your credit score is too low or you don't think you can pay off the balance in time, other paths exist. A nonprofit credit counselor can help you set up a debt management plan, where you work with creditors to lower your interest rates without taking on new debt. This doesn't require a credit check and doesn't hurt your score the way a new card application does.

Some credit unions offer credit-builder loans, which help you build credit while saving money at the same time. You borrow a small amount (usually $500 to $1,000), and the money goes into a savings account you can't touch until the loan is paid off. You make monthly payments, and once you're done, you have both a loan history and savings.

If you're drowning in debt and can't see a way out, a bankruptcy attorney can tell you whether Chapter 7 or Chapter 13 bankruptcy makes sense for your situation. Many offer free consultations. This is a last resort, but it's better than years of debt collection calls and wage garnishment.

How to compare balance transfer cards if you decide to apply

If you meet the credit requirements and think a balance transfer will work for you, compare cards on three things: the length of the promotional period, the transfer fee, and the regular interest rate after the promotion ends.

A longer promotional period (18 to 21 months) gives you more time to pay down the balance. A lower transfer fee (3% instead of 5%) means less money added to your balance upfront. A lower regular rate (15% instead of 22%) matters if you can't pay off the full balance before the promotion ends, though you should assume you will when you're deciding whether to apply.

Don't apply for multiple cards at once. Each application triggers a hard inquiry and lowers your score. Apply for one card, wait to see if you're approved, and only apply for another if the first one doesn't work out. Once you're approved, move the balance, then stop applying for new credit while you pay it down.

Frequently Asked Questions

What happens if I can't pay off the balance before the promotional period ends?

The regular interest rate kicks in on whatever balance remains. If you owe $2,000 when the 0% period ends and the card's regular rate is 20%, you'll start paying interest on that $2,000. You should assume this won't happen when you apply, but if it does, contact the card company and ask if they'll work with you on a payment plan.

Can I transfer a balance from one card to another card from the same company?

No. Most card companies don't allow you to transfer a balance from another card they issued. You have to transfer from a different company. Check the card's terms before you apply to make sure it accepts transfers from your current card's issuer.

Does applying for a balance transfer card hurt my credit score?

Yes, but usually only by a few points. The hard inquiry lowers your score temporarily, and opening a new account lowers your average account age. However, if the balance transfer lowers your overall credit utilization (the percentage of available credit you're using), that can help your score over time. The temporary dip is usually worth it if the transfer saves you money.

What if I have multiple credit cards with high balances?

You can only transfer one balance per card. If you have three cards with high balances, you could apply for one balance transfer card and move the highest-rate balance there. Keep making payments on the other two. Don't apply for three balance transfer cards at once — that will tank your credit score and looks risky to lenders.

Is there a way to get a balance transfer card with bad credit?

Some cards marketed to people with fair or poor credit offer balance transfer options, but the promotional periods are shorter (6 months instead of 12 to 18) and fees are higher. A nonprofit credit counselor is usually a better first step if your credit is below 650. They can help you build a plan that doesn't require new credit.
