Is a Balance Transfer Worth the Fee?
A 0% balance transfer can give you some breathing room. But before you move a balance, there’s a useful question to answer: will the interest you avoid be greater than the fee and any other costs?
In the example below, moving $5,000 from a card at 24% APR to an 18-month 0% offer with a 3% fee saves about $1,275 at a payment of $250 a month. That’s a substantial saving. It also depends on keeping up those payments and knowing what happens when the promotion ends.
What you’re paying for
A balance transfer moves debt to another card. An introductory offer may give the transferred balance a low or 0% APR for a limited time, with a fee charged when you make the transfer.
For this guide, we’ll compare a 3% fee with a 5% fee. On $5,000, that’s $150 or $250 added to the balance before you make your first payment. We assume the fee receives the same 0% rate as the transfer. Check the offer terms to see how your card treats it.
The other number to find is the APR after the promotion. A transfer that looks cheap for the first year can become expensive if you still owe a lot when that rate takes effect.
What happens at $250 a month
Suppose you owe $5,000 at 24% APR. You can pay $250 each month, and you’re considering a card offering 0% for 18 months. After that, the new card charges 24% too.
Here’s the estimated cost of each choice:
| Plan | Months to pay off | Total fee + interest | Saved vs. staying |
|---|---|---|---|
| Keep the current card | 26 | $1,449.37 | — |
| Transfer with a 3% fee | 21 | $174.69 | $1,274.68 |
| Transfer with a 5% fee | 22 | $281.43 | $1,167.94 |
The 3% transfer starts at $5,150. After 18 payments, $650 remains. Paying that off adds $24.69 in interest, on top of the $150 transfer fee.
The 5% transfer starts at $5,250. After 18 payments, $750 remains. Interest after the promotion comes to $31.43, on top of the $250 fee.
Both transfers save money in this example, even though neither is fully paid off during the promotion. The 3% offer costs less because we’ve kept every other term the same.
These are estimates using monthly interest and fixed payments. The final payment is smaller. The calculation details are below.
What if $150 a month is more realistic?
A longer payoff changes the comparison. Keep the same balance, fees, and rates, but lower the payment to $150:
| Plan | Months to pay off | Total fee + interest | Saved vs. staying |
|---|---|---|---|
| Keep the current card | 56 | $3,322.17 | — |
| Transfer with a 3% fee | 38 | $695.98 | $2,626.19 |
| Transfer with a 5% fee | 39 | $847.46 | $2,474.71 |
With the 3% fee, you’ll still owe $2,450 when the promotion ends. It takes another 20 months to finish, adding $545.98 in interest.
With the 5% fee, you’ll owe $2,550 at that point. It takes another 21 months, adding $597.46 in interest.
The transfer saves more dollars here because keeping the original card at $150 a month is so costly. But you’re still carrying debt for more than three years. The lower rate helps; the payment determines how quickly you make use of it.
If the new card’s rate after the promotion is higher than 24%, the remaining balance will cost more than these examples show.
The payment that clears it before 0% ends
Divide the transferred balance, including the fee, by the number of monthly payments you can make during the promotion. For our 18-payment example, rounding up to the next cent gives:
- 3% fee: $5,150 ÷ 18 → $286.12 a month
- 5% fee: $5,250 ÷ 18 → $291.67 a month
Under these assumptions, paying those amounts on time clears the balance during the promotion, leaving only the transfer fee as the cost. Your final payment will be slightly smaller because we rounded up.
Check the actual expiration date and payment dates. An offer described as “18 months” doesn’t necessarily give you 18 full payment cycles after the day you finish transferring your balance.
Check these details before you transfer
The fee and any annual fee. Include every added cost in your comparison. The tables above assume no annual fee or other charges.
The rate after the promotion. Find the APR that applies to whatever remains. Also check whether that rate is variable.
New purchases. A 0% transfer offer doesn’t necessarily give you 0% on purchases. Carrying the transferred balance can mean losing the usual interest-free grace period on purchases. The CFPB explains how that works.
Your available credit. If the transfer fee counts against your limit, leave room for it. A $5,000 limit cannot cover both a $5,000 transfer and a $250 fee.
The transfer deadline. Some offers require you to transfer within a specified time after opening the account. Read that deadline separately from the date the promotional rate expires.
The minimum payment. A 0% rate doesn’t mean you can skip payments. The CFPB explains that introductory rates generally must last at least six months, with an exception if a required payment is more than 60 days late. Read its guidance on introductory rates.
How to compare your own offer
Start with your current statement and the transfer offer. Write down your balance, current APR, fee, promotional rate and end date, and the rate afterward. Then choose a monthly payment you can realistically maintain.
Compare keeping the current card with transferring it, using the same payment for both. For the transfer, include the fee in the opening balance and account for the rate changing when the promotion ends. A spreadsheet or calculator that supports promotional rate changes can do that comparison.
If you’re paying off several cards, you’ll also need to decide where extra payments go. Our avalanche versus snowball guide explains the two approaches. For a closer look at payment size, see what an extra $100 a month does.
How we calculated the example
We started with $5,000, adding $150 or $250 for the transfer scenarios. Each month, we added interest before subtracting the payment. Interest was rounded to the nearest cent, with half-cents rounded up.
The current card uses 24% ÷ 12, or 2% per month. The transfer scenarios use 0% for the first 18 payments, then 2% per month until the balance reaches zero. The last payment covers only the remaining balance and interest.
There are no new purchases, late payments, annual fees, or other charges. Apart from the scheduled end of the promotion, rates don’t change. Actual card interest may use daily balances and different billing periods, so your statement totals can differ.
We calculated these tables separately for this article. Kalco’s current calculator does not automatically switch from a promotional APR to a later rate. Entering 0% in Kalco for the entire payoff period would leave out interest that could apply after the offer ends.
