Here I am, 31 years old, and I only just got around to really understanding the optimum way to manage my credit card. (At least I hope I understand it now).
Now for those of you that don’t like reading, I’ll give you the short version. Very simply – you MUST pay off the “Closing Balance” as close to, but before the “Due Date” ON THAT STATEMENT – and you pay no interest. Make no other payments. Do NOT pay the “Outstanding Balance”. That’s it, nothing else you need to know. Do that religiously, and you can’t do any better.
