If you're carrying a credit-card balance at the standard 36-45% APR, balance transfer (BT) can cut your interest cost by 60-80% for the next 6-12 months. The catch: lenders price BT to make money over the long run; the offer only works if you ACTUALLY clear the balance during the promotional window. Here's how to use BT correctly.
How balance transfer works
You apply to Bank B to transfer your outstanding from Bank A's credit card. Bank B pays Bank A directly; the debt now sits on Bank B's card. You repay Bank B at the promotional rate.
Two structures dominate:
- 0% interest for 60-90 days. SBI's standard offer. You pay 1-2% one-time processing fee at transfer.
- 1.7% per month (~20.4% APR) for 180 days. SBI's longer option. Cheaper than the original 36-45% but still meaningful interest.
2026 BT rate card
| Issuer | Tenure | Rate | Processing fee |
|---|---|---|---|
| SBI Card | 60 days | 0% | 1.5% (min ₹199, max ₹2,500) |
| SBI Card | 180 days | 1.7%/month | 1% (min ₹250) |
| HDFC Bank | 90 days | 0% effective (1.5% one-time) | 0.5% additional |
| Axis Bank | 180 days | 0.99%/month | 1.5% (min ₹250) |
| ICICI Bank | 90 days | 0.75%/month | 1% (min ₹199) |
The math — when does BT save you money?
Take ₹1 lakh credit-card outstanding at 42% APR (3.5%/month). Without BT, in 6 months you accrue ~₹26,000 of interest (compound).
With SBI 180-day BT at 1.7%/month + 1% processing fee:
- Processing fee upfront: ₹1,000.
- Interest over 6 months: ~₹10,200.
- Total cost: ₹11,200 vs ₹26,000 without BT — savings of ₹14,800.
The fine-print traps
- No interest-free period on retail purchases while BT exists. If you make a new ₹5K purchase during the BT period, that purchase accrues interest from day 1 (no grace period). Don't use the card for fresh spend.
- Payment allocation order is statutory: Your monthly payments first clear GST, fees, and interest, then the BT principal, then any new purchases. Translation: new purchases sit at the bottom of the priority stack and accrue interest the longest.
- BT failure to repay = revert to standard rate. If you don't clear the BT balance by the promotional end date, the standard 36-45% APR kicks in retroactively in some products. Read terms carefully.
- Multiple BTs in succession damage CIBIL. Looks like financial stress; banks flag the pattern.
Balance transfer vs converting to EMI vs personal loan
| Option | Effective rate | Best for |
|---|---|---|
| BT (180 days) | 20.4% + 1% fee | Definite ability to clear in 6 months |
| Convert outstanding to EMI | 13-22% (issuer-set) | 12-24 month structured repayment |
| Personal loan to clear card | 10.5-15% (best in class) | Larger amounts, longer tenure |
For amounts above ₹50K with 12+ months of repayment runway, a fresh personal loan typically beats BT. See our personal loan rate guide and card vs loan decision framework.
The 60-day BT plan that actually works
- Apply for SBI's 60-day 0% BT.
- Stop ALL new spending on both cards. Use a debit card for daily expenses.
- Set aside the BT amount + processing fee in your savings account before transfer.
- On day 50, pay the BT in full.
- Total cost: just the 1.5% processing fee. No interest. CIBIL improves due to lower utilisation.
Frequently Asked Questions
Can I do BT to a card I just got?
Yes — many issuers actively market BT to new customers as a welcome offer. The BT amount counts toward your card limit.
Will my old card be closed after BT?
No — BT just zeroes the outstanding. Your old card stays open. Closing it would hurt your credit history age — keep it active.
What if my BT application is rejected?
Common reasons: insufficient credit limit on the new card, recent missed payments. Apply again after 3-6 months of clean payment history.
