A 0% offer may still have a cost

Many balance-transfer offers charge a transfer fee based on the amount moved. That fee increases the effective cost even when the promotional APR is zero for a limited period.

The promotional period matters

Estimate how much you can realistically pay each month before the introductory period ends. Any remaining balance may become subject to the account terms that apply after the promotion.

Do the payoff math before transferring

Start with the transferred balance plus the transfer fee, then divide by the number of promotional months for a rough payment target. This simple target does not replace issuer disclosures but helps test whether the payoff goal is realistic.

Watch purchases and payment rules

Purchases, cash advances and transfers can have different APRs and terms. Review how payments are allocated and whether new purchases receive a grace period while a transferred balance remains.

Compare total cost, not the headline

Compare the transfer fee and expected post-promotion interest with the interest you expect to pay if you keep the existing balance. Avoid assuming that approval, credit limits or the amount eligible for transfer are guaranteed.
