Credit card grace period for pay, wait 1 day, charge?
You shouldn't be charged interest, unless possibly because your purchases involve a currency conversion. I've made normal purchases that happened to involve changes in currency.  The prices were quoted in US$ to me.  On the tail end, though, the currency change was treated as a cash advance, which accrues interest immediately. "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." This will not result in any finance charges: I wouldn't recommend cutting it quite so close, but as long as you pay the full balance as shown on each statement by the due date shown on that same statement, you won't incur a finance charge. Of course this only applies in the case of ordinary purchases that have a grace period.
"From my days in e-commerce they break down like this? The company doesn't know a debit from a credit card.  Got the Visa logo, then it is a Visa through the company's payment gateway.  The gateway talks to the bank and that is where the particulars for money is figured out. When I programmed gateway interfaces, I had the option to ""authorize"" or check for funds (which didn't reserve anything, just verified funds existed), run for batch (which put a hold on the funds and collected them at the end of the night) or just take the money. Most places did a verify during the early checkout stages and then did a batch at the end of the night.  The nightly batch allows a merchant to cancel a transaction without getting charged a fee. The ""authorize"" doesn't mean the money is tied up, although that might be your banks policy.  Furthermore, an authorize can only last for so many days.  This also explains why most of your banks don't report your transactions to you the day of.  There is a bunch more activity on your card than the transactions that complete." All standard mortgage promissory notes mandate payments are due on the first of every month; I can almost guarantee the note you signed has this provision.  Most lenders offer a grace period of generally 15 days before they assess a late charge, but the payment IS late on the 2nd.  People have become incorrectly accustomed to believe that the payment is due between the 1st and 15th. If they are servicing your loan for another investor (FNMA, FHMLC, a private investor, etc.), they may have contractual requirements to begin collection activities by a certain date. So they are within the rights you granted them.  If these calls really bug you, you can start to adjust your cashflow so you can perhaps make your payment a few days ahead of the first each month. You're knowingly providing a payment method which has insufficient funds to meet the terms of the contract, because you are too lazy to comply with the contract. That's unethical and fraudulent behavior. Will you get in trouble? I don't know. I'd suggest getting acquainted with an electronic calendar that can remind you to do things. "Played ""the balance transfer game"" once recently, just as a reference - Got a balance transfer offer for a sock drawer no-AF card. 2% up-front fee, 0% APR. Grace period was, by the time I acted on it, about 16 months. Used it to pay down an auto loan with an APR slightly higher than 2%, and brought my equity back to positive. Towards the end when I rolled over the auto loan, thanks to the positive equity I was offered a rate discount on the new loan. Essentially this was a piggyback loan on the original auto loan funded by credit card (via balance transfer). Saved some interest charges without having to refinance." Remember that if you make charges as the starting of your billing cycle, then you are receiving a free ~60-day loan. For those that are able to receive high interest rates on their, this means a greater opportunity to earn on their money. For example: Your billing statement ends on Jan 5th. On Jan 6th, you max out your credit card. Your billing statement ends on Feb 5th. Depending on your credit card, your grace period can be anywhere from 20 to 30 days. If your bill is due Mar 7th, you just gave yourself a free 60 day loan. If you have multiple credit cards with different due dates and long grace periods, you can rotate which cards you max out to optimize the money you keep in savings. Each bank is different. Usually in my experience for newer credit card accounts, there is a specific number of days in a billing cycle (something like 28) and then a 20-25 day grace period. Older accounts usually have 30+ day billing cycles. Back in the 90's, many cards also had 30-40 day grace periods. The language specific to your card is in the card agreement. It is the people who you bought the ticket from. Blocking is frequently done by hotels, gas stations, or rental car companies. Also, for anything where the credit card might be used to cover any damages or charges you might incur later as part of the transaction. In essence, they are reserving part of your credit limit, ostensibly to cover charges they reasonably expect you might incur. For example, when you start pumping gas using a credit card they may block out $100 to make sure you don't pump a full tank and your credit card is declined because you ran over your limit at $3.  In general, the blocks clear fairly quickly after you settle up with the company on your final bill. You can also ask the company to clear the block, but I don't think they are required to by law in any specific time period. It may be up to their (and your) agreement with the credit card company. Normally it isn't an issue and you don't even notice this going on behind the scenes, but if you keep your credit card near its limit, or use a debit card it can lead to nasty surprises (e.g. they can make you overdraw your account). One more reason not to use debit cards. More information is available here on the Federal Trade Commission's website. It's my understanding that the grace period is only for filing - the actual procedure/purchase must be performed CY2011 to be paid out from the 2011 FSA money, etc. I don't believe Saturday is a business day either. When I deposit a check at a bank's drive-in after 4pm Friday, the receipt tells me it will credit as if I deposited on Monday.  If a business' computer doesn't adjust their billing to have a weekday due date, they are supposed to accept the payment on the next business day, else, as you discovered, a Sunday due date is really the prior Friday. In which case they may be running afoul of the rules that require X number of days from the time they mail a bill to the time it's due.  The flip side to all of this, is to pick and choose your battles in life. Just pay the bill 2 days early. The interest on a few hundred dollars is a few cents per week. You save that by not using a stamp, just charge it on their site on the Friday. Keep in mind, you can be right, but their computer still dings you. So you call and spend your valuable time when ever the due date is over a weekend, getting an agent to reverse the late fee. The cost of 'right' is wasting ten minutes, which is worth far more than just avoiding the issue altogether.  But - if you are in the US (you didn't give your country), we have regulations for everything. HR 627, aka The CARD act of 2009, offers - ‘‘(2) WEEKEND OR HOLIDAY DUE DATES.—If the payment due date for a   credit card account under an open end consumer credit plan is a day on   which the creditor does not receive or accept payments by mail   (including weekends and holidays), the creditor may not treat a   payment received on the next business day as late for any purpose.’’. So, if you really want to pursue this, you have the power of our illustrious congress on your side. I'm pretty sure it's merchant-dependent.  If a credit card transaction doesn't go through, PayPal will automatically charge your bank account.  Some merchants may want that extra insurance. The only card I've seen offer this on credit card purchases is Discover.  I think they have a special deal with the stores so that the cash-over amount is not included in the percentage-fee the merchant pays.  (The cash part shows up broken-out from the purchase amount on the statement--if this was purely something the store did on its own without some collaboration with Discover that would not happen). The first few times I've seen the offer, I assumed it would be treated like a cash-advance (high APR, immediate interest with no grace period, etc.), but it is not.  It is treated like a purchase. You have no interest charge if you pay in full during the grace period, and no transaction fee.  Now I very rarely go to the ATM. What is in it for Discover?  They have a higher balance to charge you interest on if you ever fail to pay in full before the grace period.  And Discover doesn't have any debit/pin option that I know of, so no concern of cannibalizing their other business.  And happier customers. What is in it for the grocer?  Happier customers, and they need to have the armored car come around less often and spend less time counting drawers internally. That would have been a good idea.  They don't charge interest on a $0 balance, but if you payoff your account after the cycle date, there is a hidden balance and that balance will accrue interest. It is only a few cents a day.  I just don't think it is legal for them to refuse to provide you a payoff quote mid cycle. I'm almost certain. When I worked for Discover it was a key point in training to not give the wrong amount and to make sure to use the calculator in the system to quote a daily balance, how much it goes up per day, and how much they should send if they were mailing the payment, giving consideration for the time it takes to receive/process the payment. "AIUI this is not terribly abnormal. There are authorisations (sometimes reffered to as ""pending charges"" or ""holds"") and actual charges. An authorisation reserves money but doesn't actually take it. Normally what happens when you pay by card is that the merchant gets an authorisation immediately. Then some time later the authorisation is converted into an actual charge when the merchant takes the money. Sometimes merchants are slow in taking the actual charge, either deliberately (some merchants won't charge your card until they actually supply the goods to reduce the chance of having to process a refund) or because of administrative snarlups somewhere. When this happens the authorisation can time out before the actual charge is taken. So you get the pattern you see, first the authorisation appears then it times out and dissapears and finally the actual charge shows up." A friend of mine has two credit cards.  He has specifically arranged with the card issuers so that the billing cycles are 15 days out of sync.  He uses whichever card has more recently ended its billing cycle, which gives him the longest possible time between purchase and the due date to avoid interest. "In short you have to wait till the hold expires. If its one week, its great. Few years back it was one Month. It is advisable you use a Credit Card for these type of transactions. With Credit Cards you are not out of funds like in Debit Cards. Plus the reversals are as much as I know automatic. In case of Debit Cards, the Holds are not automatically released on cancelled transactions but released only after expiry. Where as in Credit Cards, the holds are released immediately on cancelled transactions. ""Does the hold reserve it for them or for the original transaction?"" Yes hold is for that specific transaction from that specific merchant. i.e. if you try and book the same item from the same merchant, you will not be able to as you have money blocked. Although the merchant sends an unblock message when cancelling, on Debit cards these messages are not supported in India"
