A balance transfer moves debt from one card to another. Your score can react in a few small ways, and the bigger risks are usually about money and timing. Here is what the sources support, and what they leave open.

  1. Apply or use an offer. A new card application typically means a hard credit check. An offer sent to an existing cardholder may not.
  2. Move the balance. The debt shifts to the new account, and a fee usually applies.

  2. Pay on time. A payment more than 60 days late can bring a higher rate on every balance.

What a balance transfer does

A balance transfer moves an outstanding balance from one credit card to another, sometimes for a fee. Card companies often advertise zero-percent or low-interest offers to get people to put their debt on one card, according to the Consumer Financial Protection Bureau (CFPB). The debt does not go away. You owe the same money to a different account, possibly at a different rate for a set period.

You do not always need a new card. As myFICO notes, some offers go straight to existing cardholders, including checks sent in the mail. Using one of those on an account you already have means no new application. That choice shapes what shows up on your credit report.

The hard inquiry and your score

A new card application typically involves a hard credit check. According to myFICO, one additional hard inquiry will typically lower FICO Scores by fewer than five points. That is a small dip. It is also the one score effect the sources describe with a number.

myFICO adds that a balance transfer can affect FICO Scores in both positive and negative ways. The sources reviewed describe the other effects only in part. They do not explain how a transferred balance is reported to the credit bureaus or how it changes your credit utilization. They also do not say how long the inquiry or the transfer affects a score, or whether closing the old card changes it. Treat any confident claim on those points with some doubt unless it comes with a source.

Fees and the real cost

The fee catches people off guard. The CFPB says a card company is permitted to charge a balance transfer fee even on a zero-percent offer. The fee is usually a percentage of the amount transferred or a fixed amount, whichever is more.

Here is a made-up example. Say a card charges 3 percent, with a minimum of $5. Moving $3,000 would cost $90, because 3 percent of $3,000 beats the $5 minimum. That $90 gets added to what you owe. The 3 percent figure is only for illustration. The sources reviewed give no typical fee range, so read the actual terms on any offer.

The low rate also ends. The CFPB says the promotional rate on most transfers lasts a limited time, and afterward the rate may rise and raise your payment. The CFPB also explains that APR compares interest and fees to the amount borrowed over one year. That is why an APR can look different from a simple interest rate. The sources reviewed give no typical length for promotional periods, so check the end date on your own offer.

Late payments can undo the deal

The CFPB says that if a payment is more than 60 days late, the card company can raise the interest rate on all balances, including the transferred one. One slip could erase the savings you moved the debt to get. Setting up automatic payments for at least the minimum is a common way to guard against it, though the sources reviewed do not make that recommendation themselves.

Questions to ask before you move a balance

The CFPB points to the cardholder agreement as the place that states the fees, the APR and the terms for the card. Read it, then ask the issuer these questions:

  • What is the balance transfer fee, and is it a percentage, a fixed amount, or whichever is greater?
  • How long does the promotional rate last, and what rate applies after it ends?
  • Can a fee be charged on a zero-percent offer under this card's terms?

Then compare the fee against the savings from the promotional rate. A zero-percent offer can still cost real money up front.

What we could not confirm

Several pages meant to cover scoring, including ones from the FTC, Experian, Equifax and CNBC Select, returned mostly navigation text when reviewed. Their credit-score guidance could not be confirmed, so this article does not rely on them. Scores also vary by scoring model and by the report at each credit bureau, and the sources do not address that in detail. If your score matters for a loan soon, check your own reports before you apply.
