Holiday season is when 0% balance transfer offers show up everywhere. They can save real money, or just move a problem around for a year. The difference is almost all arithmetic.

§1. Compare the fee with the interest you’d pay anyway

Most balance transfers charge a one-time fee of about 3-5% of the amount moved. Compare that with the interest you’d pay on the current card over the same period.

Example: $5,000 at 24% APR costs roughly $100 a month in interest. A 3% fee is $150, paid once. Over a 15-month promo, the transfer wins by a wide margin, if the balance is actually paid down.

§2. Divide the balance by the promo months

$5,150 (balance + fee) over 15 months is about $344 a month. If that fits the budget, the plan works. If it doesn’t, figure out what will be left when the promo ends and what APR applies to it.

§3. Don’t use the new card for purchases

On many cards, new purchases don’t get the 0% rate, and payments may go to the promo balance first while purchases build interest. Keep the transfer card for the transfer only.

§4. Mind the timing and the details

Transfers usually must be made within a set window after opening (often 60-120 days), and a single late payment can end the promo rate on some cards. Read the terms for both.

§5. Expect a small, temporary credit score effect

A new application means a hard inquiry and a new account. Lower utilization after paying down usually helps over time, and keeping the old card open (if it has no annual fee) helps utilization too.

§6. Treat it as a payoff plan, not a pause

The transfer only works if the spending that created the balance stops. A simple monthly plan with a payoff date keeps it honest.
