Credit Card Balance Transfer Calculator

What is a credit card balance transfer?

A balance transfer (BT) lets you move outstanding debt from one credit card to another — usually a card offering a low or 0% promotional interest rate for a fixed period (3-9 months). You pay a one-time processing fee (1-3% of the transferred amount + 18% GST), and you must repay the full balance within the promo period to avoid the regular revolving rate kicking in.

2026 BT offers from major banks

• HDFC SmartEMI / BT: 0% for 3-6 months, 1.5-2% processing fee, then 36% APR after
• ICICI Bank BT: 0% for 3, 6, or 9 months, 1.5-3% processing fee, then 38-44% APR
• SBI Card BT: 1.7% + GST per month flat for 6 months (effective ~24% APR), no fee
• Axis Bank BT: 0% for 60 days, 1.5% processing fee
• Kotak BT: 0% for 3 months, 1.5% processing fee

When BT genuinely saves money

• You have a sizeable balance (₹50K+) you can't clear in one cycle.
• Your current card's revolving rate is 36-48% APR.
• You can pay off the full transferred balance within the promo period.
• Your CIBIL score (700+) qualifies you for a BT offer.

When BT is a trap

• You can't clear during promo period: When the 0% rate expires, the card switches to its full revolving rate (36-48%). You're back to square one with extra fee paid.
• You keep using the original card: If you continue to charge the old card while paying off the transferred balance, you double your debt.
• Processing fee is high: A 3% BT fee + 18% GST = 3.54% upfront cost. On ₹50K, that's ₹1,770 — significant if your repayment plan was already on track.

Worked example

You owe ₹1 lakh on a card at 42% APR. You can pay ₹20K/month. Two paths:

• Stay on original card: Over 6 months at 42% APR, you pay ~₹19,500 in interest + ₹3,510 GST = ₹23,000+ in extra cost.
• BT to a 0% / 6-month card with 1.5% fee: Processing fee ₹1,500 + GST ₹270 = ₹1,770 upfront. ₹0 interest during promo. Total cost: ₹1,770. You save ~₹21,000.

Step-by-step: how to do a credit card BT in 2026

1. Get a BT offer from a different bank (you can't BT within the same bank in most cases).
2. Apply through the bank's app, branch, or by calling. Need: PAN, latest statement of card you're BT'ing from.
3. Bank approves (usually within 24-72 hours), pays off your old card directly.
4. Old card statement now shows ₹0 (or ₹0 + new charges if you used it).
5. Make the agreed monthly EMI to the new card during promo period.
6. Make sure to fully clear before promo expiry — set a calendar alert.

Don't make these mistakes

• Adding new spends to the BT card. Most BT offers apply only to the transferred amount. New purchases get charged at the full revolving rate immediately, with no grace period.
• Closing the old card after BT. Closing reduces total credit limit, hurts utilization ratio, drops CIBIL. Keep it open with a small monthly recurring charge to keep it active.
• Not reading the fine print on the promo period. Some BT offers are "0% for 3 months" not 6 — paying it off in 6 won't save anything.
