Compare the interest on your current card with a transfer fee, promotional rate and any balance remaining after the promotion.

Balance-transfer offer

This assumes the fee is added to the transferred balance and no new purchases, late fees or penalty APRs occur.

When a balance transfer may help

A lower promotional rate can reduce interest, but the transfer fee increases the starting balance. The most favorable outcome usually occurs when the balance is repaid during the promotional period and new purchases are avoided.

Offer details to verify

  • Transfer fee and maximum fee
  • Promotional expiration date

When a balance transfer actually saves money

A promotional APR can reduce interest, but the transfer fee is charged immediately and the regular APR may apply to any balance left after the promotion. The useful comparison is the total financing cost under each path, not the advertised promotional rate by itself.

How to use this page

The calculator adds the transfer fee to the starting balance, applies the promotional rate for the selected months, and then uses the post-promotion APR if a balance remains. It compares that path with continuing the current card at its existing APR and payment.

Practical exampleFor an $8,000 balance with a 3% fee, the transfer starts at $8,240. A 0% offer can still save money when the fee is smaller than avoided interest and the payment is large enough to make meaningful progress during the promotion.

Inputs to verify

  • Verify the transfer deadline and promotional expiration date.
  • Do not assume new purchases receive the same promotional terms.
  • Check whether a late payment can end the promotional APR.

Common questions

Is a 0% transfer free?

No. Most offers charge a percentage fee, and unpaid balances may later accrue interest at the regular APR.

What payment should I test?

Start with the amount required to repay the transferred balance during the promotion, then test a lower amount to understand the risk.
