How a 0% balance transfer card can help pay down credit card debt

Consumers carrying high-interest credit card debt may be able to reduce their interest costs by transferring balances to a card offering a 0% introductory annual percentage rate, financial guidance suggests.

Balance transfer cards typically allow cardholders to move existing debt from one or more cards onto a new card that charges no interest for a set promotional period, often lasting a year or more. During that window, payments go entirely toward reducing the principal balance rather than accruing interest charges.

Three steps to consider

Financial guidance generally points to a few key steps: first, comparing the length of the 0% promotional period across available cards, since longer windows give more time to pay down debt interest-free. Second, checking the balance transfer fee, typically a percentage of the amount transferred, which can offset some of the interest savings. Third, calculating a realistic monthly payment plan to ensure the balance is paid off before the promotional rate expires and a higher standard rate takes effect.

Experts caution that balance transfer cards are most effective for borrowers who can commit to a disciplined repayment schedule, since carrying a balance past the promotional period can result in retroactive or significantly higher interest charges depending on the card's terms.
