Quick answer: A balance transfer moves debt from one account to another, often to use a promotional interest rate. The transfer can reduce interest only if the total fees, timing, and repayment plan actually work in your favor.
Promotional APR is temporary
Check the exact promotional rate, how long it lasts, which transferred balances qualify, and the rate that applies after the promotional period.
Transfer fees matter
A transfer fee increases the cost immediately. Compare that fee with the interest you realistically expect to avoid rather than focusing only on the headline promotional rate.
Have a payoff plan before transferring
Divide the amount you want gone by the number of months available in the promotional window, then test whether that payment fits your budget. Avoid treating newly available room on the old card as permission to borrow again.
