CITIC's credit card has been owed to 200 yuan for almost six years, and it was lost at that time. How much is this interest? I want to go, but I'm afraid I can't afford it.
As far as 200 yuan is concerned, there is not much interest. The interest is calculated at 0.5 ‰ per day and compounded monthly. The interest is 200 * (1.015) 72-200 = 384 yuan.
