How to Use This Calculator
Fill in both sides of the comparison to get your complete balance transfer analysis:
- Current Card — Enter your existing balance, current APR (find it on your statement), and the monthly payment you can afford to make.
- New Transfer Card — Enter the promotional APR (usually 0%), the length of the promotional period in months, the balance transfer fee percentage, and the regular APR that kicks in after the promo ends.
- Calculate — Get an instant verdict on whether the transfer saves you money, plus total interest saved, break-even month, and a full cost comparison.
💡 Tip: The transfer is most valuable when you can pay off the full balance before the promo period ends. If you can't, calculate whether the regular APR on the new card is still lower than your current card.
How Balance Transfers Work
A balance transfer moves debt from a high-interest credit card to a new card — usually one offering a 0% promotional APR for a set period. The goal is to stop paying interest during the promo period so more of your payment goes toward reducing the principal balance.
The Core Formula
Net Savings = Interest Saved During Promo − Transfer Fee
Example: $8,500 balance, 24.99% APR, 15-month 0% offer, 3% fee
Monthly interest saved ≈ $177 × 15 months = $2,655 saved
Transfer fee = $8,500 × 3% = $255
Net savings = $2,655 − $255 = $2,400 ✅ Transfer is worth it
Monthly interest saved ≈ $177 × 15 months = $2,655 saved
Transfer fee = $8,500 × 3% = $255
Net savings = $2,655 − $255 = $2,400 ✅ Transfer is worth it
When a Balance Transfer Makes Sense
- Your current card has a high APR (above 15%) and you carry a balance month to month
- You can qualify for a card with a 0% or very low promotional rate
- You can pay off the balance (or most of it) before the promo period ends
- The transfer fee is less than the interest you would have paid
⚠️ Watch out for: Continuing to use the old card (doubles your debt), missing a payment (often cancels the 0% rate), and assuming the regular APR on the new card is low — it may be just as high as your original card.
Frequently Asked Questions
Does a balance transfer hurt your credit score?
Applying for a new balance transfer card causes a hard inquiry, which may temporarily lower your score by 5–10 points. However, if the transfer reduces your credit utilization ratio (balance divided by credit limit) by giving you more total available credit, your score may actually improve over time. Paying down the balance during the promo period further improves your score.
What happens if I don't pay off the balance before the promo ends?
When the promotional period ends, your remaining balance starts accruing interest at the card's regular APR — which is often 19%–29%. The transfer is still beneficial if you paid down a significant portion of the balance. Use our calculator to check: even if you don't fully pay it off, you may still save money compared to staying on your current card.
Can I transfer a balance between cards from the same bank?
No. Almost all credit card issuers prohibit balance transfers between their own cards. For example, you cannot transfer a Chase card balance to another Chase card, or a Citi card to another Citi card. You must transfer to a card issued by a different bank. Always verify the issuer before applying for a balance transfer card.
How long does a balance transfer take?
Most balance transfers complete within 5–14 business days after approval. Continue making payments on your original card until the transfer is confirmed complete — missing a payment while waiting can result in late fees and potential damage to your credit score. Call your new card issuer to confirm the transfer status if you haven't heard back within 2 weeks.
Is there a limit on how much I can transfer?
Yes. Your balance transfer limit is typically your new card's credit limit, minus any existing balance on that card. Some issuers also cap balance transfers at 75%–95% of your credit limit. If you want to transfer $8,500, you'll generally need a credit limit of at least $9,000–$10,000 on the new card.
What credit score do I need for a balance transfer card?
Most 0% APR balance transfer cards require good to excellent credit — typically a FICO score of 670 or higher. The best offers (longest 0% periods, lowest fees) usually require 720+. If your score is below 670, you may still qualify for some balance transfer offers, but the promotional period may be shorter or the fee higher. Check your score before applying to avoid unnecessary hard inquiries.
