A balance transfer is worth it when the interest you avoid is bigger than the transfer fee, and at today's card rates it almost always is. Moving $6,000 from a card at 22.15% to a 0% offer for 21 months with a 5% fee costs $300 up front and saves $1,276.32, if you pay $300 a month either way. What sinks a transfer is rarely the fee. It is new spending, a late payment, or an offer that is really deferred interest.

What current offers charge

A credit card company may charge a balance transfer fee even on a 0% offer, the CFPB confirms, and the fee is usually a percentage of the amount or a fixed amount, whichever is more. Two large issuers' own terms show what that looks like in 2026:

Terms	Promotional rate	Transfer fee	Transfers from the same bank
U.S. Bank Shield Visa	0% for the first 21 billing cycles, on transfers made within 60 days of opening	5% of each transfer, $5 minimum	Not permitted
Chase cardmember agreement	Varies by offer; standard rate 19.74% to 28.24%	$5 or 5%, whichever is greater	Not permitted

Federal rules set a floor on the promotion. The intro rate has to last at least six months unless you are more than 60 days late, and the issuer must tell you up front how long it lasts and what rate applies afterward, per the CFPB's guide to intro rates.

A worked example

Take $6,000 on a card charging 22.15%, the Federal Reserve's Q2 2026 average for card accounts that paid interest in its G.19 consumer credit release. Move it to a 0% offer for 21 months with a 5% fee.

Saved versus staying put

The fee is added to the balance, so you owe $6,300. Paying $300 a month clears it in exactly 21 months with no interest. Paying the same $300 on the old card takes 26 months and costs $1,576.32 in interest, $7,576.32 in total. The difference is $1,276.32.

These figures assume interest compounds daily at the APR divided by 365, as the Chase agreement describes, no new purchases, and one payment at the end of each month.

The break-even rate is lower than you think

Here is the APR your current card has to beat for the transfer to pay off, assuming you pay the amount that clears the transfer on time and would pay that same amount on the old card:

Promo length	3% fee	4% fee	5% fee
12 months	5.5%	7.3%	9.1%
15 months	4.5%	5.9%	7.4%
18 months	3.8%	5.0%	6.2%
21 months	3.2%	4.3%	5.4%

The average across all card accounts was 20.94% in Q2 2026, far above every number in that table. A longer promotion lowers the bar because the fee is spread over more months of avoided interest. So the fee is almost never the reason a transfer fails.

Saved by moving $6,000 to 0% for 21 months with a 5% fee, by your current APR (dollars)

Computed with daily compounding at APR/365, paying $300 a month on both cards, no new purchases.

If you cannot clear it in time

Falling short shrinks the win but rarely erases it. Say your budget allows $200 a month, not $300. After 21 months you still owe $2,100, which then accrues at the card's standard rate.

If that rate is 22.15%, clearing the $2,100 adds $258.75 of interest, for $6,558.75 in total.
If it is 28%, the total is $6,641.91.
Staying on the old card at $200 a month takes 45 months and $2,867.10 of interest, $8,867.10 in total.

Either way the transfer still saves over $2,200. The plan that fails is the one where the leftover balance meets a much higher rate and keeps growing because you are also adding new charges.

Four ways it backfires

You spend on the transfer card. The CFPB warns that new purchases on that card get no grace period until the entire balance, transferred amount included, is paid in full. Putting $500 a month on it at 22.15%, paid off each due date, costs about $257.70 of interest over 21 months, a fifth of the savings.
You refill the old card. Then you have two balances instead of one, and only one of them is at 0%.
You pay more than 60 days late. The issuer can then raise the rate on all balances, including the transferred one, according to the same CFPB page.
The offer is deferred interest. Store financing that says "no interest if paid in full" charges all the interest back to the purchase date if any balance remains, as the CFPB explains. A true 0% transfer charges interest only on what is left when it ends.

Payment rules work in your favor here. Under 12 CFR 1026.53, anything you pay above the minimum must go to the highest-rate balance first. The U.S. Bank terms say the same: the minimum goes from lowest to highest APR, and anything over it from highest to lowest.

Do this before applying

Find your payment. Divide the balance plus the fee by the promo months: $6,300 over 21 months is $300. If that is out of reach, run the shortfall numbers above with your own figures in the loan payment calculator.
Read four terms: the fee, the window to make the transfer (60 days on the U.S. Bank card), the promo length, and the rate afterward.
Set autopay for the fixed amount, not the minimum. Here is what the minimum payment costs.
Keep paying the old card until it shows the transfer as received. A missed payment there still counts as late.
Stop using the old card, but leave it open. The next section shows why.

What happens to your credit score

The application adds a hard inquiry. For most people one more inquiry takes less than five points off a FICO Score, and FICO scores count inquiries for only a year, according to myFICO. See hard vs soft inquiries.

The new credit line pushes the other way, by lowering your utilization. If you owe $6,000 against $15,000 of total card limits, your utilization is 40%. Add a $7,000 card and move the balance, and it becomes $6,300 against $22,000, or 28.6%. Close the old cards and it jumps to $6,300 against $7,000, or 90%. More on that in the credit utilization guide.

Frequently asked questions

Does a balance transfer hurt your credit score?

Slightly, at first. The hard inquiry usually costs less than five FICO points, and the extra credit line lowers your total utilization as long as you keep the old card open.

Can I transfer a balance between two cards from the same bank?

Usually not. Both the Chase agreement and the U.S. Bank Shield terms prohibit transfers from other accounts at the same bank.

What happens when the 0% balance transfer period ends?

Whatever is left starts accruing at the card's standard rate from that point. A true 0% offer does not charge interest retroactively, unlike a deferred interest deal.

Is a balance transfer worth it for a small balance?

Only if payoff will take more than about four months. On $1,000 at 22.15%, clearing it in four months costs $46.99 of interest, less than a $50 fee, while a five-month payoff costs $56.56.

Is the balance transfer fee added to the balance?

Yes. A $6,000 transfer with a 5% fee becomes $6,300, and the fee also uses up credit line, so on a $5,000 limit the most you can move at 5% is $4,761.90.

How long does a balance transfer take?

It varies; Discover says timing depends on factors such as the status of the accounts and how they are paid. Keep making payments on the old card until the transfer shows up there.

Is a balance transfer better than a personal loan?

If you can clear it within the promo, usually yes. A 24-month bank personal loan averaged 11.86% in Q2 2026, which on $6,000 costs $769.17 in interest, versus a $300 transfer fee.

Should I close the old card after a balance transfer?

Usually not. Closing it removes its limit and can push your utilization up sharply; leave it open with a $0 balance unless it charges an annual fee.
