Balance Transfer Calculator

Introduction

A balance transfer lets you move debt from one credit card to another, usually to get a lower interest rate. This can save you money and help you pay off your debt faster. Our Balance Transfer Calculator makes it easy to see how much you could save by switching your balance to a new card. Just enter your current balance, interest rate, and the details of the new card, and the calculator will show you the difference in cost. It's a quick way to find out if a balance transfer is a smart move for your wallet.

How to Use Our Balance Transfer Calculator

Enter your current credit card details and the new card's terms to see how much money and time you can save by transferring your balance.

Current Credit Card Balance: Type in the total amount you owe on your current credit card right now. This is the balance you want to move to a new card.

Current Card Interest Rate (APR): Enter the annual percentage rate on your existing credit card. You can find this number on your monthly statement or by calling your card company. If you're unsure how APR affects your costs, our APR Calculator can help you understand the true cost of borrowing.

Current Monthly Payment: Put in the amount you pay toward your credit card bill each month. This helps figure out how long it will take to pay off your debt.

Balance Transfer Fee (%): Enter the one-time fee the new card charges to move your balance over. Most cards charge between 3% and 5% of the amount you transfer.

New Card Interest Rate (APR): Type in the interest rate on the new credit card. If the new card has a 0% intro rate, enter 0 here.

Promotional Period (Months): Enter how many months the low or 0% intro rate lasts on the new card. After this period ends, the regular interest rate will kick in.

Post-Promotional Interest Rate (APR): Put in the regular interest rate that applies after the promotional period is over. This is the ongoing APR listed in the new card's terms.

What Is a Balance Transfer?

A balance transfer is when you move debt from one credit card to another, usually to take advantage of a lower interest rate. Many credit card companies offer special introductory APR deals—sometimes as low as 0%—for a set number of months. This lets you pay down your debt faster because more of your monthly payment goes toward the actual balance instead of interest charges. To see exactly how much interest your current card is costing you each month, try our Credit Card Interest Calculator.

How Does a Balance Transfer Work?

When you apply for a balance transfer card, the new card issuer pays off your old credit card debt. Your balance then lives on the new card, often at a much lower promotional interest rate. This promotional period typically lasts anywhere from 6 to 21 months. Once the promotional period ends, the interest rate jumps up to the card's regular APR, which can sometimes be even higher than your original card's rate.

Most balance transfer cards charge a balance transfer fee, usually between 3% and 5% of the amount you transfer. For example, if you move $5,000 to a new card with a 3% fee, you will owe an extra $150 right away. This fee gets added to your new balance. That is why it is important to do the math before you commit—the savings from lower interest need to be greater than the cost of the fee for a transfer to make sense.

Key Terms to Know

• APR (Annual Percentage Rate): The yearly interest rate your credit card charges. Divide it by 12 to find the monthly rate applied to your balance.
• Introductory APR: The temporary low rate offered on a balance transfer card. It only lasts for the promotional period.
• Post-Promotional APR: The regular interest rate that kicks in after the introductory period ends. Any remaining balance will accrue interest at this higher rate.
• Balance Transfer Fee: A one-time charge, calculated as a percentage of the transferred balance, added to your new card's balance at the start.
• Monthly Payment: The fixed amount you pay each month. Keeping this amount the same—or increasing it—after a transfer helps you pay off debt faster during the low-rate window. You can use our Minimum Payment Calculator to see how paying only the minimum affects your timeline.

When Does a Balance Transfer Save You Money?

A balance transfer is most helpful when you carry a large balance on a high-interest credit card and you are confident you can pay off most or all of the debt during the promotional period. The bigger the gap between your current APR and the introductory APR, the more you save. However, if you only make minimum payments and still have a large balance when the promo period ends, the new card's higher regular APR could wipe out your savings or even cost you more. Our Credit Card Payoff Calculator can help you figure out exactly how long it will take to eliminate your balance under different payment scenarios.

Tips for Getting the Most Out of a Balance Transfer

• Pay as much as you can during the intro period. Divide your total balance by the number of promotional months to set a target monthly payment that clears the debt before the rate goes up.
• Avoid new purchases on the transfer card. New charges may not qualify for the intro rate and can accumulate interest immediately.
• Never miss a payment. A late payment can cancel your promotional rate and trigger a penalty APR that is much higher.
• Factor in the transfer fee. A 0% intro APR sounds great, but a 5% fee on a large balance can add up. Always compare the fee against the interest you would otherwise pay.
• Check your credit score first. The best balance transfer offers generally require good to excellent credit. Applying for a card you do not qualify for can result in a hard inquiry on your credit report with no benefit.
• Have a broader debt payoff strategy. If you carry balances across multiple cards or loans, consider using the Debt Avalanche Calculator or Debt Snowball Calculator to build a comprehensive repayment plan.

What the Results Tell You

This calculator compares two paths: keeping your current credit card versus transferring the balance to a new card. It shows you the total interest paid, total amount paid, and how many months it takes to become debt-free under each scenario. The net savings figure is the most important number—it subtracts the transfer fee from the interest savings to show whether the balance transfer actually puts money back in your pocket. A positive net savings means the transfer is worth it. A negative number means you are better off staying with your current card and focusing on paying it down. To understand how interest compounds on your remaining balance over time, our Compound Interest Calculator provides additional insight. You may also want to check your DTI Calculator to see how your overall debt load compares to your income as you work toward becoming debt-free.

Frequently Asked Questions

What is a balance transfer fee and how is it calculated?

A balance transfer fee is a one-time charge the new credit card company adds when you move your debt over. It is a percentage of the amount you transfer. For example, if you transfer $5,000 and the fee is 3%, you pay $150. This fee gets added to your new card balance right away, so your starting balance on the new card is higher than what you owed on the old card.

What happens if I don't pay off my balance before the promotional period ends?

Once the promotional period ends, the post-promotional APR kicks in on whatever balance is left. This rate is often higher than your original card's rate. Interest starts building on the remaining balance at the new higher rate, which can eat into or erase the savings you got during the intro period. That is why paying off as much as possible before the promo ends is so important.

Why does the calculator say my payment is too low?

If your monthly payment is less than or equal to the monthly interest charge on your balance, your debt will never go down. Each month, interest adds more than you pay off, so the balance stays the same or grows. The calculator needs your payment to be higher than the monthly interest so your balance actually shrinks over time.

What does net savings mean?

Net savings is the total interest you save by transferring your balance minus the balance transfer fee. If the number is positive, the transfer saves you money. If it is negative, you would actually spend more by transferring, and you are better off keeping your current card.

Should I transfer my balance if the net savings is very small?

If the net savings is only a few dollars, a balance transfer may not be worth the hassle. You have to apply for a new card, manage a new account, and make sure you never miss a payment. A small savings might not justify the effort and risk of losing a promotional rate due to a missed payment.

What is the effective rate shown in the comparison section?

The effective rate shows the total interest you pay (plus the transfer fee for the new card) as a percentage of your original balance. It gives you a simple way to compare the true cost of each option. A lower effective rate means that option costs you less overall.

Can I transfer a balance from more than one credit card?

Yes, many balance transfer cards let you move balances from multiple cards. To use this calculator for that situation, add up all the balances you want to transfer and enter the total as your current card balance. The transfer fee will apply to the entire amount you move.

What does the amortization table show me?

The amortization table breaks down every single month of your repayment. It shows your starting balance, how much interest is charged, how much of your payment goes to principal, and your ending balance. It also tracks cumulative interest so you can see the total interest paid up to any point in time.

What does the Intro and Regular label mean in the transfer card table?

The label tells you which interest rate applies for that month. Intro means you are still in the promotional period and paying the low introductory APR. Regular means the promo period has ended and the higher post-promotional APR is now being charged on your remaining balance.

Does this calculator account for minimum payments?

This calculator uses a fixed monthly payment amount that you choose. It does not automatically calculate or enforce a minimum payment. You should make sure the monthly payment you enter is at least as high as the minimum payment your card requires, or the results will not be realistic.

Why is my total paid on the transfer card higher even though interest is lower?

This happens because the balance transfer fee gets added to your balance on the new card. Even though you pay less in interest, the fee increases the total amount you owe. If the fee is large enough, your total paid on the transfer card can end up higher than staying with your current card.

What introductory APR is most common for balance transfer cards?

The most common introductory APR is 0%. Many credit card issuers offer 0% APR for anywhere from 6 to 21 months. Some cards offer a low rate like 2% or 5% instead of 0%. The length of the promo period and the transfer fee vary by card, so always compare the full terms.

How do I know what my current credit card APR is?

You can find your APR on your monthly credit card statement, usually near the interest charges section. You can also log into your account online or call the number on the back of your card and ask. Make sure you use the APR for purchases, not the cash advance APR, which is usually higher.

Will a balance transfer hurt my credit score?

Applying for a new credit card triggers a hard inquiry on your credit report, which can lower your score by a few points temporarily. However, if the transfer lowers your credit utilization ratio (the percentage of available credit you are using), your score could actually improve over time. Avoid closing your old card right away, as that reduces your total available credit.

What if I enter 0% for both the introductory APR and post-promotional APR?

If both rates are 0%, you will pay zero interest on the transfer card. Your only extra cost is the balance transfer fee. The calculator will show your total paid as the original balance plus the fee, with no interest at all. This scenario is rare in real life since post-promotional APRs are almost always above 0%.
