How do “held” amounts appear on statements and affect balances of traditional credit cards?
"The ""hold"" is just placeholder that prevents you from overspending until the transaction is settled. The merchant isn't ""holding"" your money, your bank or card provider is protecting itself from you overdrawing. In general, it takes 1-3 days for a credit transaction to settle. With a credit card, this usually isn't an issue, unless you have a very low credit line or other unusual things going on. With pre-paid and debit cards, it is an issue, since your spending power is contingent upon you having an available balance. I'm a contrarian on this topic, but I don't see any compelling reason to use debit or stored value cards, other than preventing yourself from overspending. I've answered a few other questions in detail in this area, if you're interested."
A few things for you to consider: (1) Yes, if your average daily balance is lower [because you paid it off when you received your paycheck, then slowly used the card for the remainder of the month, until it's at the same balance next paycheck, vs just having the card at a flat $5k the whole month], you will accrue less interest, thereby allowing you to pay it off faster by reducing your interest payments.  BUT: (2) Carrying a balance on your credit card is a big financial no-no, and eliminating it should be an immediate priority for you. If there is anything you can do (step 1: budget your expenses and then track actuals to see where you stand - step 2: see what expenses you can reduce - step 3: see if you can increase your income - step 4: rebudget with your new goals, determine how long it would take to pay off the card, possibly considering consolidating/refinancing your debt at a lower interest rate) to pay it off faster, then do it. However (3) If you have absolutely zero cash on hand, then taking your paycheck and immediately paying down your credit card, and then relying on that card to pay for things until the next paycheck, puts you at risk of your available credit changing. ie: if you have 5k on the card, and pay it down to 4.25k, then what happens to you if the credit card company [because they view you as a risk, or for whatever other reason - including a temporary hold because of fraudulent activity at no fault of your own] reduces your available credit to 4.5k? Suddenly, you will only have $250 in available spending power until your next paycheck. Therefore it may be wise for you to hold onto some amount of cash that you do not touch except for emergencies, even before you pay off your credit card. I really recommend you search this site for other questions related to budgeting and credit cards. There are many good answers, and some of what I've said above is just opinion, so you shouldn't just take my word for it, you should try to become familiar with these topics yourself. Good luck! "The debt isn't ""paid off"" until you've brought the balance back to zero. If you pay less than the full amount, some goes to pay down the balance and some goes to paying interest on the balance, and you're left with a debt on the account (which you add to if you continue using the card or reduce when you make a payment to the card.) Note that the ""grace period"" in which you can pay off recent charges without paying interest is often available only when you have paid off the card in full... so carrying a balance costs you money on new charges immediately. Check your statements and plan paperwork to see if this applies to you; if it does that's another reason to pay off this debt as quickly as possible. Not to mention that credit card interest rates tend to be moderately obscene." In general, minors cannot enter into legally binding contracts --   which is what credit accounts are -- so an individually held card is   probably not an option for you right now. You will not be approved for a credit card because you are minor. The only option credit card wise for you is for your parents to add you on as an authorized user onto their accounts. The upside is that you and your parents can work out a monthly payment for the amount you spend on your equipment, the downside is that if your parents don't pay their credit card bill, your credit score/report can be negatively affected. (This also depends on the bank, however, all the banks I bank with report monthly payment activities on authorized users' credit reports as well. There might be a bank that doesn't.)  In terms of credit cards, there is nothing you can do. What you could do as the comments have suggested is either save up money for the equipment you want, or buy something cheaper. The cost to the store is small. They may have to pay a slightly greater fee because the transaction is now bigger. They do need additional cash on hand. Even though the majority of transactions are electronic (credit/debit) or check, the local grocery store still seems to have significant cash on hand. This is seen as a customer service. If there is a 2% fee the $50 advance costs them $1 for the minority of customers that take advantage of it. After more than 10 years of doing this they have figured this into the cost of groceries. Of course the credit card company could also waive the fee to store. My credit card online statement does tell me how much cash back was received. The line says date, store, amount ($40.00 cash over and $123.45 purchases) $163.45 total. Therefore the credit card company knows that cash back was used. "To avoid nitpicks, i state up front that this answer is applicable to the US; Europeans, Asians, Canadians, etc may well have quite different systems and rules. You have nothing to worry about if you pay off your credit-card statement  in full on the day it is due in timely fashion. On the other hand, if you routinely carry a balance from month to month or have taken out cash advances, then making whatever payment you want to make that month ASAP will save you more in finance charges than you could ever earn on the money in your savings account. But, if you pay off each month's balance in full, then read the fine print about when the payment is due very carefully: it might say that payments received before 5 pm will be posted the same day, or it might say before 3 pm, or before 7 pm EST, or noon PST, etc etc etc. As JoeTaxpayer says, if you can pay on-line with a guaranteed day for the transaction (and you do it before any deadline imposed by the credit-card company), you are fine.  My bank allows me to write ""electronic"" checks on its website, but a paper check is mailed to the credit-card company. The bank claims that if I specify the due date, they will mail the check enough in advance that the credit-card company will get it by the due date, but do you really trust the USPS to deliver your check by noon, or whatever? Besides the bank will put a hold on that money the day that check is cut. (I haven't bothered to check if the money being held still earns interest or not).  In any case, the bank disclaims all responsibility for the after-effects (late payment fees, finance charges on all purchases, etc) if that paper check is not received on time and so your credit-card account goes to ""late payment"" status.  Oh, and my bank also wants a monthly fee for its BillPay service (any number  of such ""electronic"" checks allowed each month). The BillPay service does include payment electronically to local merchants and utilities that have accounts at the bank and have signed up to receive payments electronically. All my credit-card companies allow me to use their website to authorize them to collect the payment that I specify from my bank account(s). I can choose the day, the amount, and which of my bank accounts they will collect the money from, but I must do this every month. Very conveniently, they show a calendar for choosing the date with the due date marked prominently, and as mhoran_psprep's comment points out, the payment can be scheduled well in advance of the date that the payment will actually be made, that is, I don't need to worry about being without Internet access because of travel and thus being unable to login to the credit-card website to make the payment on  the date it is due. I can also sign up for AutoPay which takes afixed amount/minimum payment due/payment in full (whatever I choose)  on the date due, and this will happen month after month after month  with no further action necessary on my part.  With either choice,  it is up to the card company to collect money from my account on the day specified, and if they mess up, they cannot charge late payment fees or finance charge on new purchases etc.  Also, unlike  my bank, there are no fees for this service. It is also worth noting that many people do not like the idea of the credit-card company withdrawing money from their bank account, and so this option is not to everyone's taste." It will depend on credit they are offering you during the period being covered. A gas station locks up what they expect is the maximum transaction for most people. When the prices of gas spikes some people have the pump turn off before the tank is filled, therefore they need to use a 2nd card to complete the purchase. Before you arrive at a hotel they lockup the cost of one night in the hotel, that way they still sell the room for one night if you never show. While you are there they lockup the cost of what you could owe them. This would include the cost of the room, and average room service or bar service.  For a car rental, it would be based on the risk they perceive. They don't want to try and collect against a card you gave them when you reserved the car, or when you picked up the car, only to find that you have gone over the limit.  Some online systems will let you see what is pending against your card. Others could provide that information to you over the phone. Trick question dude. Can't be done. Sorry to tell you. I've been hit with this. Credit card companies do not make money on these customers. Why does Amex have an annual fee on all cards and an abnormally large transaction fee for merchants? Because they don't allow you to carry a balance (On traditional cards). Meaning they don't make money on interest, like the customers in question here. I paid with my Visa credit card. Generally on credit cards, the holds / authorizations are valid for a month on single transactions. So if you haven't been charged on your card, it seems that there was some technical error with the online market place. They were not able to trace this. Is there an expiration date on these kind of online purchases? Should I expect the money to be withdrawn at any time? There are 2 different aspects, one is do you still owe them money and can they ask you; It would be yes, I don't know the timelines. This would depend on establishing a contract etc. They can contact you for unpaid invoice. Can they again charge the credit card automatically ... generally No.
