Quick answer: To do a balance transfer, check your eligibility, compare 0% APR offers, apply, then request the transfer using the new card’s online portal or app. Keep paying the old card until the transfer posts, then divide the new balance (plus the fee) by the number of promo months to get your monthly payoff target.
Key takeaways
- A balance transfer moves high-interest card debt to a card with a temporary 0% (or very low) APR.
- Most transfers cost a one-time fee, commonly in the range of 3% to 5% of the amount moved (estimate; check each offer).
- Keep making the minimum payment on the old card until the transfer fully posts.
- The real plan is the math: balance divided by promo months equals your monthly payment.
- New purchases on the transfer card can undo the savings. Stop using it.
If you are paying 20% or more on a credit card, every month you wait costs real money. A well-run balance transfer can pause that interest and let every dollar you pay go straight to the principal. Here is exactly how to do a balance transfer, and how to make the numbers work in your favor.

What a Balance Transfer Actually Does
A balance transfer moves debt from one credit card to another. The new card pays off the old card, and you now owe the new issuer instead. The appeal is the introductory rate, which is often 0% APR for a set number of months.
Here is why it matters, using a simple example (illustrative numbers):
- Balance: $6,000 at 24% APR.
- Interest on the old card: roughly $120 a month at the start.
- On a 0% card: that $120 goes to principal instead.
Over 18 months, that difference can add up to well over $1,000 in interest saved, even after a transfer fee. For a deeper look at the mechanics, see our balance transfer guide.
Step 1: Check Your Eligibility
Before you apply, find out where you stand. The best 0% offers generally go to people with good to excellent credit, which is commonly considered a score in the high 600s to 700s and up (a rough guide, since issuers set their own criteria).
Run through this checklist:
- Check your credit score through your bank, card issuer or a free report service.
- Pull your free credit reports at AnnualCreditReport.com, the federally authorized site, and fix any errors.
- Look at your utilization. Balances close to your limits can hurt approval odds.
- Note which cards you already have. Most issuers will not let you transfer a balance between two of their own cards.
Step 2: Compare Offers on the Numbers That Matter
Do not choose a card by the headline alone. Line up two or three offers and compare these items:
- Promo length. Longer is usually better, with some offers running 12 to 21 months (varies by issuer).
- Transfer fee. Often 3% to 5% of the amount transferred (estimate). A $6,000 transfer at 3% costs about $180; at 5%, about $300.
- Ongoing APR. This is what applies to any leftover balance after the promo ends.
- Credit limit. You can only transfer up to the limit you are approved for, minus the fee.
- Transfer window. Some cards require you to transfer within the first 60 days or so to get the promo rate.
Pro tip: A 0% offer with a 3% fee for 21 months can beat a 0% offer with no fee for 12 months if you need the extra time. Run both through the math before you decide.
A transfer fee is not a penalty. It is the price of buying months of interest-free payoff.
Step 3: Apply and Request the Transfer
Once you pick a card, apply. If approved, you will usually be able to request the transfer one of three ways:
- During the application, by entering the old account details.
- Online or in the app, after approval, using the issuer’s balance transfer tool.
- By phone, by calling the number on the back of your new card.
You will need the old card’s account number and the exact amount to move. Request enough to cover the balance, but remember the fee gets added on top, so the transfer amount plus the fee must fit within your new limit.
Step 4: Keep Paying the Old Card Until the Transfer Posts
This is the step people skip, and it can cost them. A transfer can take anywhere from a few days to a couple of weeks to complete (timing varies). Until it posts, your old balance is still due.
- Make at least the minimum payment on the old card on time, every time.
- Check both accounts to confirm the old balance dropped and the new one rose.
- Pay any small leftover amount. Interest that built up before the transfer may leave a small balance behind.
A missed payment can trigger a late fee and a credit hit, and some issuers can end a promo rate if you pay late. Do not leave this to chance.
Step 5: Divide the Balance by the Promo Months
Now for the part that makes the transfer work. Take your new balance (including the fee) and divide it by the number of promo months. That is your monthly payoff target.
- Example: $6,180 balance (including a 3% fee) over an 18-month promo.
- The math: $6,180 divided by 18 equals about $343 a month.
- Safety cushion: aim to finish a month or two early, so $6,180 divided by 16 is about $386.
If that number is more than you can afford, you have options: pick a longer promo, transfer a smaller amount, or pair the transfer with a larger plan.

Balance divided by promo months is the only number that matters once the transfer posts.
Step 6: Avoid New Purchases and Other Traps
The most common way a balance transfer fails is not a bad card. It is a habit. Protect your progress with these rules:
- Do not use the new card for purchases. Rules for how payments are applied vary, and new spending can accrue interest at the regular rate.
- Do not run up the old card again. A cleared card is not extra spending room.
- Set up autopay for at least the minimum, plus a calendar reminder for your full target payment.
- Mark the promo end date. Whatever remains when the promo ends starts accruing interest at the card’s regular APR.
When a Balance Transfer May Not Be the Right Move
A transfer is a tool, not a cure-all. It may not fit if:
- You cannot realistically pay the balance off within the promo window.
- The fee plus any remaining interest wipes out your savings.
- Your credit is not strong enough to get a meaningful limit.
In those cases, a lower-rate consolidation loan or a focused payoff plan like the debt avalanche method may serve you better. Our debt payoff plans guide compares the approaches.

Frequently Asked Questions
How long does a balance transfer take?
Often anywhere from a few days to about two weeks, though timing varies by issuer. Keep paying the old card until you see the balance drop.
Is there a fee to do a balance transfer?
Most cards charge a one-time fee, commonly around 3% to 5% of the amount transferred (estimate). Some offers have lower or no fees, so compare before you apply.
Can I transfer a balance from one card to another at the same bank?
Usually not. Most issuers do not allow transfers between their own accounts, so you will typically need a card from a different issuer.
What happens if I do not pay it off before the promo ends?
The remaining balance starts accruing interest at the card’s regular APR. That is why dividing your balance by the promo months, and finishing early, is so important.
