Moving an expensive outstanding balance from one credit card to another offering a lower introductory interest rate can genuinely save meaningful money, provided you understand exactly what happens once that promotional window ends, and plan accordingly rather than being caught off guard.
How a Balance Transfer Actually Works
You apply to transfer an existing outstanding balance from one card to another, typically a different issuer's card offering a promotional balance transfer rate. Once approved, the new issuer pays off your old card's balance directly, and you now owe that same amount to the new card instead, generally at a considerably lower interest rate for a specified promotional period.
The Processing Fee Is Worth Calculating Into Your Decision
Balance transfers typically carry a one-time processing fee, commonly a percentage of the transferred amount, this fee should be weighed against the interest savings you'd achieve during the promotional period, for a large balance transferred over a long promotional window, the interest savings usually far exceed this one-time fee, but it's worth running the actual numbers rather than assuming this holds true for every situation.
The Promotional Rate Is Temporary, and This Detail Matters Most
The lower interest rate offered on a balance transfer typically applies only for a specified promotional period, commonly a few months to around a year, after which the rate reverts to the new card's standard revolving interest rate, often just as high as the rate you were originally trying to escape. If you haven't cleared the transferred balance by the time the promotional period ends, you could find yourself back in an expensive revolving debt situation, simply on a different card.
A Worked Example
Say you transfer a ₹1 lakh balance from a card charging 3.5% monthly interest to a new card offering 0% for 6 months, with a 2% processing fee. The processing fee costs ₹2,000 upfront, but you avoid roughly ₹21,000 in interest over those 6 months compared to staying on the original card, a clear net saving, provided you have a genuine plan to pay off the balance within or shortly after that 6-month window.
Why a Repayment Plan Is Essential, Not Optional
A balance transfer without a specific plan to actually pay down the principal during the promotional period simply delays the underlying problem rather than solving it, calculating a fixed monthly payment amount that would clear the balance before the promotional rate expires, and sticking to that plan, is what actually makes a balance transfer a genuine financial improvement rather than a temporary reprieve.
Does a Balance Transfer Affect Your Credit Score?
The application for the new card (or the balance transfer facility) triggers a hard inquiry, as discussed in our guide on choosing a card, and your utilisation ratio shifts, potentially improving on your old card (now at zero or a lower balance) while increasing on the new one, the net effect on your score depends on your overall utilisation across both cards after the transfer.
Balance Transfer vs a Personal Loan for the Same Purpose
As discussed in our credit card versus personal loan guide, a personal loan taken specifically to pay off high-interest credit card debt is a related strategy, offering a fixed rate and defined repayment schedule for the full tenure, rather than a temporary promotional window, worth comparing both options specifically for a larger balance where a temporary transfer might not provide enough time to fully repay.
What Happens to Your Old Card After the Transfer
Your old card typically remains open with a zero (or reduced) balance after the transfer, you're not required to close it, and in fact keeping it open can help your utilisation ratio and average account age, as discussed in our CIBIL score guide, provided you don't simply run up a fresh balance on it again while also repaying the transferred amount.
Frequently Asked Questions
Can I transfer a balance between two cards from the same bank?
This varies by issuer, some banks don't permit balance transfers between their own cards, since the promotional offer is generally designed to attract a competitor's customers, worth checking your specific bank's policy if this is what you're considering.
What happens if I cannot fully repay the balance before the promotional period ends?
The remaining balance reverts to the new card's standard interest rate, which could be similarly high to your original card's rate, at this point, you might consider a further balance transfer to another promotional offer, though repeatedly doing this isn't a sustainable long-term debt strategy and can affect your credit profile through frequent applications.
Is there a limit to how much balance I can transfer?
Yes, this is typically capped by the new card's available credit limit, and the specific issuer's balance transfer policy, worth confirming the maximum transferable amount before assuming your full existing balance can be moved.
Does a balance transfer count as a new purchase for reward points on the receiving card?
Generally no, balance transfers are typically treated as a distinct transaction type and don't earn regular purchase rewards, worth confirming this with your specific issuer rather than assuming a transferred balance contributes to reward-earning or spending-based milestones.
