For the best comparison between the hundreds of different credit cards available, it helps to know just what kind of credit card user you are. If you have no hesitation about using your card, but are equally disciplined in paying off any balance each month, then you can take full advantage of the effective “interest free” period between purchase and each monthly settlement date. On most cards, this will allow you a reasonably long 59-day period of grace – though there are some which grant a shorter period, and others which allow none at all, so you would need to be careful to avoid these.
