Formula Used
Transfer fee = max(transfer balance × fee rate, minimum fee).
Starting balance = transfer balance + transfer fee + new purchase balance.
Monthly interest = current balance × APR ÷ 12.
Closing balance = opening balance + interest + monthly fee share − payment.
Total cost = transfer fee + total interest + annual fee charges.
Effective APR = total cost ÷ original balance ÷ payoff years × 100.
Estimated savings = old card interest − new transfer total cost.

Balance Transfer APR Planning Guide
A balance transfer can reduce interest, but it is not always free. The headline rate often shows only the promotional APR. The real cost also includes the transfer fee, annual fee, possible purchase interest, and the rate after the offer ends.
Why The True Cost Matters
A zero percent offer may still cost money on day one. Most issuers add a fee to the moved balance. That fee becomes part of the debt. A larger fee can reduce the value of a longer promo period. This calculator helps compare those tradeoffs in one place.
Promo Period Strategy
The intro period is the most important window. Payments made during this time reduce principal faster. If the balance is paid before the regular APR starts, interest may stay low. If a balance remains, the regular APR can raise the final cost quickly.
Payment Planning
Monthly payment size changes everything. A small payment may leave too much balance after the offer. A stronger payment can shorten payoff time and improve savings. The schedule shows each month, so you can see how interest and payments affect the balance.
Comparing Your Current Card
The calculator also estimates the cost of staying with the old card. It uses the current APR and the same monthly payment. This gives a practical savings estimate. Positive savings means the transfer may help. Negative savings means fees and later interest may outweigh the offer.
Important Card Rules
Many cards treat purchases differently from transfers. New purchases may not receive the same promo rate. Payment allocation rules can also affect interest. Always read the card terms before applying. Use the result as a planning estimate, not a final bank statement.
FAQs
What is a balance transfer APR?
It is the interest rate charged on debt moved from one card to another. Some cards offer a low or zero introductory APR for a limited time.
Does a zero percent balance transfer mean free borrowing?
No. Many cards charge a transfer fee. You may also pay interest if the balance remains after the promotional period ends.
How is the transfer fee calculated?
The fee is usually a percentage of the transferred balance. Some cards also have a minimum fee. This calculator uses the greater value.
What happens after the intro APR ends?
The remaining balance is charged at the regular APR. Paying more during the promo period can reduce that later interest.
Should I include new purchases?
Yes, if you plan to use the card for purchases. Purchases may have a different APR and can change the total cost.
Why is effective APR useful?
Effective APR converts total fees and interest into a yearly rate estimate. It helps compare offers with different fees and promo lengths.
Can this calculator replace card terms?
No. It gives an estimate. Card agreements may include special rules, payment allocation terms, penalty APRs, and grace period conditions.
What payment should I choose?
Choose a payment you can afford every month. A payment that clears the balance before the promo ends usually gives the best savings.
