How to Do a Balance Transfer
To do a balance transfer, compare 0% intro APR offers on both intro length and transfer fee, apply for the card, then request the transfer with your old account number and the amount to move. Keep paying the old card until its balance reads zero, then pay the new card aggressively during the 0% window. The most common mistakes are transferring between cards from the same issuer and missing a minimum payment, which can void the 0% rate.
Step 1: Check your credit score
The best 0% offers, with 18 to 21 month intro windows, generally go to applicants with scores of 670 or higher, and the longest windows are usually reserved for 720 and up. Check your score before you apply so you target offers you can actually get. Below 670, you may still qualify for a shorter window or a lower limit, but the math gets tighter, so be more careful with the fee.
Step 2: Compare offers on two numbers, not one
Two numbers decide whether an offer is good: the intro window length and the transfer fee. A 21-month window with a 5% fee can be worse than an 18-month window with a 3% fee, depending on your balance. Also note the regular APR that applies after the intro period, in case you carry a leftover balance, and confirm that transfers from your current issuer are allowed, because most issuers block transfers between their own cards.
Step 3: Apply for the new card
Apply directly with the issuer you chose. You will get a credit limit, which is usually decided in the application or shortly after. If the limit is lower than the balance you wanted to move, you have two options: transfer a partial balance (still useful, because every dollar moved stops accruing interest) or apply with a different issuer. Do not request a transfer amount above your approved limit minus the fee.
Step 4: Request the transfer
Many issuers let you request the transfer during the application. Otherwise, request it in the new account's online portal or by phone. You need the old card's account number, exactly as printed on your statement, and the dollar amount to transfer. Request the transfer the same day you are approved, because the 0% clock usually starts at account opening, not when the transfer posts.
Step 5: Keep paying the old card until the balance is zero
The transfer takes 5 to 7 business days, sometimes up to 14. Interest keeps accruing on the old card during that wait, and the old due date does not pause. Leave autopay at the minimum payment until you see a $0 balance on the old card, then turn it off. Any overlap between your autopay and the transfer landing is refunded to you.
Step 6: Pay the new card down hard during the 0% window
During the intro period, every dollar you pay goes to principal instead of interest. Divide what you owe by the number of intro months to get your target monthly payment, then automate it. This is where the real money is: a disciplined payoff schedule is the difference between saving four figures and paying a fee for nothing.
A worked example
Say you move $4,000 at 21% APR to an 18-month 0% card with a 3% fee. The fee is $4,000 times 3%, which is $120, so your new balance starts at $4,120. To clear it inside the 0% window, divide $4,120 by 18 months: $228.89 per month.
Paying $228.89 a month for 18 months costs you exactly $4,120, with zero interest. Compare that to staying on the old card, where a $4,000 balance at 21% APR with the same payment takes about 21 months and costs roughly $640 in interest on top. Run your own numbers in the balance transfer calculator to see the side-by-side totals for your balance and payment.
Mistakes that void the 0% rate
Three mistakes can cost you the intro rate entirely:
- Missing a minimum payment. Most issuers cancel the 0% intro rate if you pay late, and the balance jumps to the regular APR or a penalty APR. Set autopay for at least the minimum on day one.
- Making new purchases on the transfer card. Many cards apply your payment to the 0% balance first, while new purchases accrue interest at the regular APR from day one. Use the new card only for the transferred balance until it is paid off.
- Taking a cash advance. Cash advances carry their own high APR and fees, and the intro rate does not cover them.
Can you transfer between cards from the same bank?
Usually no. Most major issuers explicitly block balance transfers between their own cards, because the point of the offer is to win business away from a competitor. If your high-APR balance is with a particular bank, look for a 0% offer from a different bank. Some smaller issuers and credit unions allow internal transfers, but treat this as the exception and confirm in writing before you apply.
Common questions
Do I need the new card in hand before requesting the transfer?
No. Most issuers let you request the transfer during the application, and the request processes as soon as the account is approved. Waiting for the physical card to arrive just burns days off your intro window.
Can I transfer only part of my balance?
Yes, and it is often smart. If your new limit is lower than your old balance, transfer what fits and keep the rest on the old card. Every dollar moved to 0% is a dollar that stops accruing interest.
How much of my balance can I transfer?
Most issuers cap transfers at your approved credit limit, and the transfer fee counts against that limit. As a rule, request no more than about 90 to 95% of your limit so the fee fits and the request is not held or partially approved.
Can I transfer a balance from a store card or a personal loan?
It depends on the issuer. Many allow transfers from store cards and other credit cards; some allow personal loans or auto loans, and most do not allow mortgages. Check the new card's transfer terms before you count on it.
What if I cannot pay off the full balance before the intro ends?
Any remaining balance starts accruing interest at the card's regular APR. Plan for this from day one: divide the transferred amount by the intro months to get your target payment. If that payment is not realistic, a shorter payoff plan or a different strategy, like a personal loan, may fit better.
