About Credit Card Balance Transfer Calculator

A balance transfer swaps an interest-bearing card balance for a promotional period at zero or low rate, in exchange for an upfront fee. The transfer pays only if the interest avoided over the promo exceeds that fee — and only if the balance clears before the promo ends.

Formula

Transfer test

Net saving = Σ(balance × monthly APR over promo) - balance × fee%

Frequently Asked Questions

What happens if the balance is not cleared in time?

The residual reverts to the new card's standard rate, which can undo the whole saving.

Do new purchases share the promo rate?

Often not. Purchases may accrue at the normal rate and payments may be applied to the promo balance first.
