<prompt> Human: Im 23, I made a bad decision and let my mom use my credit card to buy my sister a laptop and textbooks for school a while ago. Im getting hit with finance charges of 50-70month. I live at home and dont pay rent, make 1600month at work.Mint.com and CreditKarma suggest transferring the balance to this card with 0 APR for 18-month. Should I do that? Will doing that damage my credit score?  <response>: If there are no charges for the balance transfer, then paying 0 is always better than what youre currently paying. If youre currently paying 60 on a 3600 balance per month, then your interest rate is apparently something like 20. If you pay down 900 per month, after the first month youll pay 45 on a 2700 balance, then 30 on a 1800 balance, then 15 on a 900 balance, then 0. So by transferring the money for 0 to a 0 interest rate, you could save yourself roughly 60453015 or 150. Well worth the trouble. If there would be a balance transfer fee of say 2, then thats 2 of 3600 or 72. Thats still less than 150. If the balance transfer fee would be 4, then thats 144 and I think it wouldnt be worth the trouble anymore.
