How a balance transfer works
A balance transfer moves your credit card balance to a new card, often one offering a 0% introductory APR for a set number of months. During that window, every payment goes to principal because no interest accrues.
The trade-off is the transfer fee, usually a percentage of the balance, plus the risk that any balance left when the intro period ends starts accruing at the standard APR.
This calculator runs two scenarios on the same balance and payment: stay on your current card, or transfer to the intro offer. It reports months to payoff in each case and your net savings.
When a transfer saves you money
The savings come from the interest you skip during the intro window. The transfer fee is a one-time cost, so the longer you hold the balance at 0%, the more the fee pays for itself.
In the default scenario, $5,000 at 20% APR with $200 a month takes 33 months and about $1,600 in interest. The same plan through a 12 month 0% offer with a 3% fee clears in 27 months and costs roughly $150 in fees, for savings near $1,050.
The transfer is only worth it if you can pay the balance down hard during the promo. Whatever remains at the end accrues at the standard APR, and the clock restarts.
The math is not the whole story
A transfer can help you pay off debt faster, but a new card with a higher credit limit can also invite new spending. If the old card stays open, resist the urge to run it up again.
Balance transfer fees can stack if you hop from card to card chasing offers. Run this calculator before each transfer and keep the payoff date in view, because the cheapest fee is the one you pay once.
| Plan | Months to payoff | Total cost |
|---|---|---|
| Current card | 33 months | $6,600 |
| Transfer (3% fee, 12 month 0% APR) | 27 months | $5,550 |
