💳 Balance Transfer Calculator
Compare keeping your current credit card balance vs. transferring it to a 0% APR card. Calculate interest savings, transfer fees, payoff months, and the break-even point. See if a balance transfer is worth it for you.
What Is a Balance Transfer Calculator?
A balance transfer calculator helps you determine whether transferring your credit card balance to a new card with a 0% introductory APR is a smart financial decision. It compares two scenarios:
- Keep Current Card: Continue paying off your balance on your existing card.
- Balance Transfer: Move your balance to a new card with a promotional 0% APR.
The calculator factors in the transfer fee (typically 3–5% of the balance), the 0% promotional period, and the post-promo APR to give you a complete picture of your total cost and potential savings.
How Does the Balance Transfer Calculator Work?
The calculator simulates two payoff paths month by month:
Net Savings = Current Card Interest − (Transfer Fee + Post-Promo Interest)
For the transfer path, the calculator applies 0% interest during the promotional period. After the promo ends, any remaining balance accrues interest at the post-promo APR. For the current card path, interest accrues at your current APR every month.
The calculator also shows the break-even point , how many months it takes for the interest savings to offset the transfer fee. If the break-even point is within the promotional period, the transfer is likely worth it.

❓ Balance Transfer Calculator FAQ
What is a balance transfer?
A balance transfer moves your existing credit card debt to a new card that offers a low promotional rate , often 0% APR , for a limited time. You pay a one-time transfer fee (typically 3–5% of the balance).
When does a balance transfer make sense?
A balance transfer makes sense when the transfer fee is less than the interest you'd pay on your current card during the promotional period. With the average credit card APR at 22.8% in 2026, a 3% transfer fee often pays for itself in under 2 months.
What is a typical balance transfer fee?
Most US issuers charge 3% or 5% of the transferred amount. Some credit unions offer 0% fee transfers. The calculator includes the fee in the comparison so you can see the true cost.
What is the break-even point?
The break-even point is the number of months it takes for your monthly interest savings to cover the transfer fee. For example, with a $5,000 balance at 22.8% APR and a 3% fee, the break-even is about 2 months.
What happens after the 0% promo period ends?
Any remaining balance after the promotional period accrues interest at the post-promo APR (typically 18–29%). The calculator simulates this to show your total cost if you don't pay off the balance in time.
What is the 0% promo period?
The 0% promotional period is the time during which no interest accrues on transferred balances. Typical offers range from 12 to 21 months, though some cards offer up to 24 months.
How accurate is this calculator?
This calculator provides accurate estimates based on standard amortization formulas and typical credit card terms. However, actual savings depend on your specific card terms, payment timing, and whether you continue using the card. Always check with your card issuer for exact rates and fees.
Is this calculator free to use?
Yes, this calculator is completely free to use. No registration or personal data storage is required. All calculations are performed in your browser.
What is the difference between APR and interest rate?
APR (Annual Percentage Rate) represents the total borrowing cost, expressed as a yearly rate. For credit cards, it includes interest and fees. The calculator uses APR to calculate monthly interest charges.
Can I transfer multiple card balances?
Yes! You can transfer balances from multiple cards to one new card, but the total transfer amount cannot exceed your new card's credit limit. This calculator assumes a single balance transfer for simplicity.
