hi guys,
i want to know how the bank calculate cc interest...

my statement date is on the 18th of evry month, and i need to pay the amount before 7th the next month. if i pay full, then there's no prob. wut if i pay half before 7th? then my balance will be charge with interest?

lets say i settle the other half of outstanding amount before the 15th, around 1 week after the last date for payment. will i be charged with interest as well?

thanks for ur guidance...
