Itrytoplease   10 #13 Posted August 18, 2017 Could it be that the minimum charge depends on the length of the month, probably the preceding month, Feb will be cheaper as there are less days for interest to accrue, etc...  You might be right there.  Don't get me wrong, he has no problem paying the card, he just couldn't understand why the first payment after he'd paid £100.00 more than required was always higher than the previous months payment  I use the spreadsheet methord as well lol. but my mate is not computer savvy.
