Credit card grace period for pay, wait 1 day, charge?
If I understand you correctly, no you shouldn't be charged interest. Lets say you have a billing cycle of monthly (which usually isn't true). You charge $XX per day, ending up at $1000 at the end of January. So February 1st, your bill for your January billing cycle is $1000, due by Feb 15th (lets say). On February 1st, you continue to charge $XX per day. You go to pay your bill online on Feb 14th (to be safe), and you'll usually see on your credit card website something like: You'd hit "Pay my bill", and you'd usually see these options: At the date your cycle was due (Feb 15th), if you haven't paid your full latest statement (lets say you paid $500), they will charge you interest on the entire balance for the period (so interest on $1000, or lets say $50). The other $500 will roll over to the next month, so your next month you'd be somewhere near a $1550 bill.
