Credit Card Balance Transfer Calculator

Balance transfer saving after the fee. A transfer only pays if you clear a large share of the balance during the promotional period, because the fee is charged immediately and the post-promotional rate is usually no better than the original.

Also called: 0 apr transfer calculator, credit card transfer saving.

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for United States change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

The fee is charged upfront on the transferred amount. During the promotional period little or no interest accrues, so payments go almost entirely to principal, which is where the benefit comes from. When the promotion ends the rate typically returns to a level similar to the original card, so a balance still outstanding is back where it started having paid a fee for the privilege. The payment needed to clear within the promotion is therefore the number that decides whether the transfer is worth doing.

3% of 6,000 is a 180 fee, so 6,180 has to clear over 18 promotional months, which is 343.33 a month. Paying the offered 350 clears it with a month to spare.

Method and limits

What it assumes

  • A level payment and no new spending on either card.

What it deliberately does not model

  • New purchases on the transfer card may not get the promotional rate and can complicate the payment allocation.
  • Missing a payment can void the promotional rate entirely.
  • A transfer opens a new account, which affects credit history length.

Frequently asked questions

Is a zero percent transfer free?
No. The fee, typically three percent, is charged upfront. On a short promotional period that fee can exceed the interest saved.
What happens when the promotion ends?
The rate reverts, usually to a level similar to what you left. A balance still outstanding is back where it started, having paid a fee.
