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
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.
