Credit Card Balance Transfer Calculator

Estimate whether an introductory balance-transfer offer saves interest under the same monthly payment.

Credit Card Balance Transfer Calculator estimate

Enter values, then calculate.

How the estimate works

The transfer balance adds the entered fee, applies the introductory APR for its stated months, then applies the post-intro APR until payoff.

Worked example

Example: a 3% fee adds $300 to a $10,000 transfer. The offer only helps if intro-period and post-intro interest savings exceed that fee.

Important limitation

Offers can include deferred terms, new-purchase rates, payment allocation rules, and lost grace periods. Results are estimates only and are not financial, lending, legal, tax, or investment advice.
