Actually I abit confuse on this BT stuffs.
Exp, I spend 8K of my total 10k CL on Oct. So I do BT on Nov to other bank? So if I choose 12 month to settle, how is the interest will charge?
Let say just take any one of the bank offer.

Because, I see some ppl can settle the amount. But they prefer to do BT, and use the cash for something else or some business.
My question is, how we calculate the BT and how actually so calle the bank interest calculated. At least can do comparison to settle or do BT better.

Thanks
