Credit Card Balance Transfer Calculator
See how much you'd save moving your balance to a promotional-rate card
Frequently Asked Questions
Savings = interest you'd pay on your current card during the promo period, minus the transfer fee, minus any interest charged at the new promotional rate during that same period. A 0% promo rate means that last term drops to zero.
Most balance transfer offers charge 3-5% of the transferred amount as a one-time fee, though some promotional periods waive it entirely — check the specific card's terms.
It's how long it takes for your interest savings to offset the one-time transfer fee. If you'll pay off the balance faster than the break-even point, the transfer fee may cost more than it saves.
Any remaining balance typically reverts to the card's standard ongoing APR, which is often much higher than your original rate — plan to pay off the transferred balance within the promotional window.
How balance transfer savings are calculated
Net savings = (interest you'd have paid on the old card during the promo period) − (transfer fee) − (interest charged at the new promo rate during that period, zero if it's a 0% offer). Break-even = transfer fee ÷ (old card's monthly interest cost).
