A 0% APR balance-transfer card can reduce the interest you pay on credit-card debt, but only if the transfer fee is less than the interest you expect to avoid and you can repay the balance before the promotional rate ends. It moves eligible debt; it does not erase it. Your offer’s fee, approved credit limit, promotional period and later APR determine whether the math works.
Is the “over half” and “25%” debt statistic verified?
Not by the available source. Northwestern Mutual’s 2020 Planning & Progress Study reported that Americans carrying debt devoted 33% of their monthly income to paying it off, excluding mortgages. That is not the same as saying over half of Americans with debt spend 25% of their income on repayments. The study’s findings were collected before COVID-19’s steepest effects, so they should not be treated as a current estimate either.

Without the original survey behind the “over half” and “25%” claim—including its sample, date and definition of debt and income—it is not possible to verify that exact statistic. The decision about a balance transfer is better made from your own balance, APR, offer terms and budget.
What a 0% APR balance transfer does—and doesn’t do
A balance transfer moves an outstanding balance from one credit card to another, sometimes for a fee. The new card may charge 0% APR on eligible transferred balances for a limited introductory period. When that period ends, any remaining balance is generally subject to the card’s non-promotional APR. The Consumer Financial Protection Bureau (CFPB) explains these mechanics in its credit-card key terms.
#1 Best Overall
A zero promotional APR is not the same as no cost: the transfer fee may be charged upfront, and interest can apply to any balance left after the promotion. Check the offer’s disclosure and cardholder agreement for the exact terms, including how payments are allocated if the account has both transferred debt and new purchases.
Compare the transfer’s cost with the interest you could avoid
Use the specific offer—not the “0%” headline—to compare costs. The CFPB reported that balance transfers among the 25 largest issuers averaged a 4.3% fee, with an average minimum fee of $5.51, in the second half of 2024. Those are market averages published in its December 2025 Consumer Credit Card Market Report, not a prediction of the fee on your offer.
For a rough first comparison, estimate the fee as the amount you plan to transfer multiplied by the offer’s fee rate, subject to any stated minimum. Then compare that amount with the interest you expect to pay on the old card over the same period. The actual result depends on your old balance, APR, payment timing, transfer completion date and how much you pay down. APR is the standard way to compare borrowing costs, but an introductory rate and a fee still need to be considered together.

Check whether you can repay the balance before the promotion ends
Divide the amount you plan to transfer by the number of promotional months to get a rough monthly payoff target. For example, use the offer’s actual number of months and your actual transfer amount; the result is a planning estimate, not necessarily the required minimum payment. Check the agreement for the minimum-payment formula and leave room in your budget for unexpected expenses.
Before applying, confirm that the debt is eligible and that the new card’s approved limit is likely to accommodate the amount you want to move. A limit below your balance may mean only part of the debt can be transferred. Issuers may also restrict transfers from accounts they own, so verify eligibility and deadlines in the current offer and agreement.
What to verify in the offer before applying
- Transfer fee: Check the percentage, any minimum fee and when the fee is charged.
- Transfer deadline and promotional length: Confirm when the transfer must be completed and how long the introductory APR applies.
- Credit limit and eligible amount: Determine how much of your existing balance can actually move.
- APR after the promotion: Find the standard balance-transfer APR that applies if you still owe money at the end.
- New purchases and payment allocation: Check whether purchases have a different APR and how payments are applied across balances.
- Payment requirements: Read the agreement’s minimum-payment terms and compare the amount needed for your payoff plan with what you can reliably afford.
When a balance transfer is more or less promising
The option is more promising when your current balance has a high APR, the fee is modest compared with the interest you expect to avoid, enough credit is approved to move a meaningful amount, and your budget supports repayment before the promotion expires.
Rank #4
- Add funds to your Amazon gift card balance, then use your balance to manage how much you spend while shopping.
- Set up Auto-Reload to automatically reload your gift card balance on a particular date, week, month or when your balance gets low (below a certain amount).
- Save up for a purchase by adding funds to your gift card balance.
- Checkout faster when you reload to your gift card balance in advance.
- Reloaded funds never expire and have no fees.
It is less promising if the fee consumes the likely savings, the approved limit leaves most of the debt behind, or you expect to add new balances instead of paying down what you transfer. It can also be a poor fit if a substantial amount will remain once the standard APR applies. No card can guarantee savings without the actual offer terms and a realistic repayment plan.

How to find current card terms
Card terms change and approval limits are individual. The CFPB says its Terms of Credit Card Plans survey collects information from more than 150 issuers twice a year; the survey is useful for market context, not a substitute for a current offer. The CFPB retired its interactive Explore Credit Cards tool because the source data was not timely enough for consumer comparisons. Check the issuer’s current disclosure and your personalized offer before deciding.
