Maybank CC user here. I always pay my credit card statement immediately when they appear online, but I kinda overspent during a recent trip recently.

Minimum payment amount: RM0.00
Outstanding balance: RM2,765.11 Pay Any Amount Now
Statement balance: RM957.04 Pay Now
Payment due date: 26 January 2015
Statement date: 06 January 2015

I've already paid the RM957.04 online a few days ago, but it still shows that amount there. Why?

Also Minimum payment amount is RM0. Meaning I won't get charged anything extra if I don't clear my outstanding balance this month?

It remained at RM957.04 before and after I paid that RM957.04.

What exactly is Statement balance? The balance I must make sure to pay before each bill cycle, or kena charge interest?

Yeah, outstanding balance reduced when I paid that RM900+
