Are there any credit cards with a statement period longer than 1 month?
Most credit cards will allow you to pick the closing date. In fact almost every bill with the exception of utilities that collected usage by reading a meter at the house will either let you pick the closing date each month, or at least have several to pick from. They won't let you pick the length, but they will let you pick the day of the month. When I worked a job that paid once a month. I wanted all my bills due early in the month: get paid, pay bill, know how much I have left. When I went back to every other week spreading them out made more sense. No credit card had a problem with this. The transitional cycle was not the correct length, but after that it was fine. As Dheer pointed out extending the cycle to 90 days would involve them extending credit for much longer than they would be comfortable. Also the goal of keeping utilization under 30% would be very difficult, you would have to keep your spending per month to less than 10% of your credit limit. Some people have trouble not falling behind on credit card bills, having to set aside the money to pay the bill every 90 day may be way to tough for many people. If the billing cycle is 2 to 3 months, it would mean Banks have to give credit for a longer period and it makes the entire business less profitable as well as more risky compared to the Monthly billing cycle. For example the current monthly billing cycle with a date say of 14th, means if you swipe your card on 1st day, one would effectively get a credit for 30+14, around 44 days. If you swipe on last day, one would get a credit for 14 days. On an average 22 days of credit. If we make this 3 months, the credit period would increase on an average (90+14)/2, 52 days. From a risk point of view, on monthly cycle if there is non-payment its flagged much earlier compared to a 3 months cycle. On offering different dates, shop around. In the older times the cycles were different, however with individuals having several cards, and trying to optimize every purchase to maximize credit period. Quite a few banks have streamlined it to monthly cycle. Shop around and some banks should be able to offer you different dates.
"You ask about the difference between credit and debit, but that may be because you're missing something important. Regardless of credit/debit, there is value in carrying two different cards associated with two different accounts. The reason is simply that because of loss, fraud, or your own mismanagement, or even the bank's technical error, any card can become unusable for some period of time. Exactly how long depends what happened, but just sending you a new card can easily take more than one business day, which might well be longer than you'd like to go without access to any funds. In that situation you would be glad of a credit card, and you would equally be glad of a second debit card on a separate account. So if your question is ""I have one bank account with one debit card, and the only options I'm willing to contemplate are (a) do nothing or (b) take a credit card as well"", then the answer is yes, take a credit card as well, regardless of the pros or cons of credit vs debit. Even if you only use the credit card in the event that you drop your debit card down a drain. So what you can now consider is the pros and cons of a credit card vs managing an additional bank account -- unless you seriously hate one or more of the cons of credit cards, the credit card is likely to win. My bank has given me a debit card on a cash savings account, which is a little scary, but would cover most emergencies if I didn't have a credit card too. Of course the interest rate is rubbish and I sometimes empty my savings account into a better investment, so I don't use it as backup, but I could. Your final question ""can a merchant know if I give him number of debit or credit card"" is already asked: Can merchants tell the difference between a credit card and embossed debit card? Yes they can, and yes there are a few things you can't (or might prefer not to) do with debit. The same could even be said of Visa vs. Mastercard, leading to the conclusion that if you have a Visa debit you should look for a Mastercard credit. But that seems to be less of an issue as time goes on and almost everywhere in Europe apparently takes both or neither. If you travel a lot outside the EU then you might want to be loaded down with every card under the sun, and three different kinds of cash, but you'd already know that without asking ;-)" "Whether or not the specific card in question is truly 0% interest rate for the first 12 months, such cards do exist. However, the bank does make money out of it on the average: Still, 12 months of not having to think about paying the bill. Nice. This is exactly what they want you to do. Then in 12 months, when you start thinking about it, you may find out that you don't have the cash immediately available and end up paying the (usually very large) interest. It is possible to game this system to keep the ""free"" money in investments for the 12 months, as long as you are very careful to always follow the terms and dates. Because even one mishap can take away the small profits you could get for a 12 month investment of a few thousand dollars, it is rarely worth the effort." For this scheme to work, you would require an investment with no chance of a loss. Money market accounts and short-term t-bills are about your only options. The other thing is that you will need to be very careful to never miss the payment date. One month's late charges will probably wipe out a few months' profit. The only other caveat, which I'm sure you've considered, is that having your credit maxed out will hurt your credit score. Yes, but note that some credit card companies let you create virtual cards--you can define how much money is on them and how long they last.  If you're worried about a site you can use such a card to make the payment, then get rid of the virtual number so nobody can do dirty deeds with it. In practice, however, companies that do this are going to get stomped on hard by the credit card companies--other than outright scams it basically does not happen.  (Hacking is another matter--just pick up the newspaper.  It's not exactly unusual to read of hackers getting access to credit card information that they weren't supposed to have access to in the first place.) So long as you deal with a company that's been around for a while the risk is trivial. It is called trailing interest, and you can read about it [here](http://www.extracreditcards.com/trailing-interest/).  edit: IIRC, the argument is that resulting total interest charges are lower for the customer calculating the interest this was as apposed to whatever the alternative is. The sneakiness is that you don't expect to owe another $1.50 on the next statement, neglect to remit the payment on it, and boom, late fee. I used to encourage my clients to overpay their account when trying to achieve a payoff. "In the US, if your monthly statement was issued by the credit card company on January 1 and it showed a balance of $1000, then a payment must be made towards that balance by January 25 or so, not February 1 as you say, to keep the card in good standing. The minimum payment required to keep the card in good standing is specified in your monthly statement, and failure to meet this requirement can trigger various consequences such as an increase in the interest rate charged by the credit card company. With regard to interest charges, whether your purchase of $2000 on  January 3 is charged interest or not depends entirely on what happened the previous two months.  If you had paid both your monthly statements dated November 1 and December 1 of the previous year in full by the their respective due dates of November 25 and December 25, and the $1000 balance on the January 1 statement is entirely due to purchases (no cash advances) made in December, then you will not be charged interest on your January purchase of $2000 as long as you pay it off in full by February 25 (the charge will appear on your February 1 statement). But, if you had not paid your December 1 statement in full by December 25, then that $1000 billed to you on January 1 will include  purchases made during December finance charges on the unpaid balance from the previous month  plus finance charges on the purchases made during December. The finance charges will continue to accumulate during January until such time as you pay off the bill in full (these charges will appear on your February 1 statement), hopefully by the due date of January 25. But even if you pay off that $1000 in full on January 25, your charge of $2000 on January 3 will start to accumulate finance charges as of the day it hits the account and these finance charges will appear on your February 1 statement.  If you paid off that $1000 on January 10, say, then maybe there will be no further finance charges on the $2000 purchase on January 3 after January 10 but now we are getting into the real fine print of what your credit card agreement says. Ditto for the case when you pay off that $1000 on January 2 and made the $2000 charge on January 3. You most likely will not be charged interest on that $2000 charge but again it depends on the fine print. For example, it might say that you will be charged interest on the average of the daily balances for January, but will not be charged interest on purchases during the February cycle (unless you miss the February 25 payment and the whole cycle starts all over again). As a general rule, it takes two monthly cycles of payment in full by the due date before one gets into the state of no finance charges for new purchases and effectively an ""interest-free"" loan of $2000 from January 3 (date of purchase) till February 25 (due date of payment).  Matters become more complicated when cash advances are taken from a credit card which are charged interest from the day they are taken but don't trigger finance charges on new purchases or the so-called ""zero percent balance transfer offers"" are accepted." "Well, I answered a very similar question ""Credit card payment date"" where I showed that for a normal cycle, the average charge isn't due for 40 days. The range is 35-55, so if you want to feel good about the float just charge everything the day after the cycle closes, and nothing else the rest of the month. Why is this so interesting? It's no trick, and no secret.  By the way, this isn't likely to be of any use when you're buying gas, groceries, or normal purchases. But, I suppose if you have a large purchase, say a big TV, $3000, this will buy you extra time to pay. It would be remiss of me to not clearly state that anyone who needs to take advantage of this ""trick"" is the same person who probably shouldn't use credit cards at all. Those who use cards are best served by charging what they can afford to pay at that moment and not base today's charges on what paychecks will come in by the due date of the credit card bill." 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. 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. I'm in the US, and I can't speak for all credit cards, but I have done this in the past. I've paid extra on my credit card, and had a positive balance on my credit card account. The purchases made after paying extra were applied to the balance, and if there was money left over on the statement closing date, I didn't owe anything that month.  Of course, I didn't incur any interest charges, but I never pay interest anyway, as I always pay my statement in full each month and never take a cash advance on my credit card.  You could call your credit card company and ask them what will happen, or if you are feeling adventurous, you could just send them some extra money and see what happens. Most likely, they will just apply it to your account and give you a positive balance. How would you respond to these cases: Limited card options - If someone has a bad credit record the cards available may only be those with an annual fee.  Not everyone will have your credit record and thus access to the cards you have. Some annual fees may be waived in some cases - Thus, someone may have a card with a fee that could be waived if enough transactions are done on the card.  Thus, if someone gives enough business to the credit card company, they will waive the fee. On the point of the rewards, if the card is from a specific retailer, there could be a 10% discount for using that card and if the person purchases more than a couple thousand dollars' worth from that store this is a savings of $200 from the retail prices compared to what would happen in other cases that more than offsets the annual fee.  If someone likes to be a handyman and visits Home Depot often there may be programs to give rewards in this case. Credit cards can be useful for doing on-line purchases, flight reservations, rental cars and a few other purchases that to with cash or debit can be difficult if not close to impossible. Some airline cards have a fee, but presumably the perks provide a benefit that outweigh that fee over the year. I'm thinking of the Citibank cards tied to American Airlines, first year free, then an $85 fee. If you have a credit card with no interest free period, there is no drawback as you will be saving interest the sooner you pay it off. However, if you have a credit card with an interest free period, the drawback on paying it earlier than the due date (such as when you first get the statement) is that you lose out on interest. For the period between when you first recieve the statement to when it is due, you could have your money earning you interest in a high interest paying savings account. Depending on how much you spend on your credit card each month and the interest rate you get, this may add up to quite a bit of additional cash each year. 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. If the rate is the same, then clearing one card to zero does have one advantage: getting your grace period back. Generally when you owe money on your credit card, and you make a new purchase that new purchase get charged interest starting on day one. But if you are not carrying  a balance, in other words you pay off the charges every month, then new purchases aren't charged until you fail to pay the balance by the due date. That grace period can be 25 to 55 days depending where you are in the billing cycle. Having one clean card will allow you to use that card when you have no other choice. Lets say you have an emergency car repair while away from home. You don't have $500 in cash so you put it on the clean card. When you get home you know that you can pay the bill and not have been charged interest. Many mutual funds include such mechanisms. However, the higher fees for those funds (when compared to simple index funds) may cancel out any improvement the hedging strategy offers.
