Opening 5 credit cards at once with no history to ruin, is it a good idea?
"I would not call this a ""good"" idea. But I wouldn't necessarily call it a bad idea either. Before you even consider it, you need to do a little bit of soul searching. If there is ANY chance that having multiple credit cards could entice you to spend more than you otherwise would, then this is definitely a bad idea. Avoiding temptation is the key to preventing regrettable actions (in all aspects of life). Psychoanalysis aside, let's take a mathematical approach to the question. I believe your conclusion is correct if you add some qualifiers to it: A few years from now, then your credit score will probably be higher than if you just had 1   credit card. Here are some other things to consider: And, saving the best for last: As for the hard inquiries, they should only have an effect on your credit score for 1 year (though they can be seen on your report for 2 years). Final thought: if you decide to do this (and I personally don't recommend it), I would keep the number of applications smaller (3-5 instead of 10-15). I also would only choose cards that have no annual fee. Try to choose 1 card that has 1-2% cash back and make that your regular card." Yes, this is definitely possible. You can optimize your credit worthiness within 18 months, you would first start with a secured credit card just to establish a little bit of credit history and then use that as a jumping point 6 months later to do several unsecured credit card applications. As a student, your primary limiting factor will be your truthful income when you apply for the cards, resulting in low limits, where using less than 30% of those limits is not a useful amount of money. Your credit scores can be looked at as a spendable balance. New inquiries spend some of that balance, low utilization earns you more of the balance. They will trend upwards with the right approach, and you can use the balance at their highs to time more inquiries. Note: My answers typically differ in that I narrowly tailor my answers to the question asked, and don't masquerade or acknowledge the idea of advice. Impulsive spenders with credit have bad credit, I can live with that.
If your accounts have an overdraft facility, then every open account is classed as available credit which has a negative effect on your credit score.  It's not normally a major concern but it is a factor.   (nb. this definitely applies to the UK, maybe not where you are) "The biggest (but still temporary) ding you'll see on your credit score from opening a new account is from the low average (and low minimum) account age.  This will have a stronger effect than the hard pull of the credit report, which is still a factor (but not much of one if you only have 1-2 pulls in the past couple years).   Having a lower average account age increases your risk to lenders.  Your average will go up by one month per month, and each time you open an account it will suffer a drop proportional to the number of accounts you already had open before.  So if you want to have a more ""solid"" credit score that stays strong in the face of new accounts in the future, it's better to open a few more accounts now (assuming you can ride out the temporary drop in score and aren't planning to go e.g. mortgage-shopping in the very near future).   Having an additional line of credit will also likely cause your credit card utilization (total balance / total credit limit, expressed as a percentage) to decrease, which would tend to increase your credit score, counteracting the age factor, unless your utilization is already extremely low (which it probably is given your monthly account payoffs).  There are various credit score simulators out there, from places that show you your credit score, and you can put in a hypothetical new card account to see the immediate likely impact for your particular situation.   You identified other costs, such as risk of fraud and fees.  You should check your statements once in a while even if you're not using the card, just to make sure no one else is.  The bit of additional time required for this is a nonzero cost of having an open credit card account.  So is the additional hassle of dealing with having the card stolen etc. if you carry it in your wallet and your wallet's stolen. If you have an account with zero activity for some number of years, the bank may close it automatically and that can reflect negatively on a credit report (as a bank closure of the account, the reason is often obscured).  Check your terms and conditions and/or have some activity every so often to prevent this from happening.   Some of the otherwise most attractive credit cards have monthly or annual fees, which will cost you, and you won't want to close those because it would then reduce your credit score (e.g. by reducing the total available credit and increasing your utilization percentage) - so the solution is don't apply for credit cards that have monthly/annual fees.  There are plenty of good cards without those fees. With a credit score that high, you can get cards that have some very good benefits and rewards programs, as well as some with great introductory offers.  Though I'm not familiar with details of Amazon's offer, $80 cash up-front with nothing else seems unlikely to be among your best options.  I would think that for at least some of the fee-free cards available to you, the benefits exceed the costs, and you could ""cash in"" some of the benefits of your good credit record to get those benefits (i.e. this is one of those things you work hard to build good credit for), while also building your long-term reputation for repayment reliability.   Also be aware as you shop around for cards that credit card companies pay fairly high referral fees to websites that send customers their way, so if you want you can think about who you're supporting when you click the link that takes you to an application you complete, and choose to support a site you think is providing a useful consumer-focused service.   As factors affecting your credit score in addition to payment history (i.e. making regular payments as agreed on the new account will help you), Equifax lists:" If you have the money and the determination to pay off all the cards in six months, then the order will make little difference to your credit score, and to your finances.  If you had less money available (say you could pay off $500 a month in total), then it would be good for financial reasons to pay off the credit card with the highest interest rate first, so you pay less interest. It would be good for psychological reasons to pay the card with the smallest amount first (so you feel successful quickly, and some people need that feeling of success to continue paying off, just psychological). And if these things contradict each other, figure out what is more important.  And whatever you do, paying back your debt is better than not paying it back. So if you can't make up your mind, then you pay #1, then #2, then #3, then #4, then #5. The U.S. bankruptcy laws no longer make it simple to discharge credit card debt, so you can't simply run up a massive tab on credit cards and then just walk away from them anymore.  That used to be the case, but that particular loophole no longer exists the way it once did. Further, you could face fraud charges if it can be proven you acted deliberately with the intent to commit fraud.   Finally, you won't be able to rack up a ton of new cards as quickly as you might think, so your ability to amass enough to make your plan worth the risk is not as great as you seem to believe. As a closing note, don't do it.  All you do is make it more expensive for the rest of us to carry credit cards.  After all, the banks aren't going to eat the losses.  They'll just pass them along in the form of higher fees and rates to the rest of us. If you are planning to get new cards, it is probably best to open the accounts as soon as possible to start establishing a history of good credit use. You might also wish to open multiple accounts so that future lines will have less of an impact on your average age of open credit lines. Since you will probably have higher interest rates it is also advisable never to carry a balance on any of your newly acquired cards. This will prevent a recurrence of the problems you are now trying to recover from. Your plan will work to increase your total credit capacity (good for your credit score) and reduce your utilization (also good).  As mentioned, you will need to be careful to use these cards periodically or they will get closed, but it will work. The question is whether this will help you or not.  In addition to credit capacity and utilization, your credit score looks at things like These factors may hurt you as you continue to open accounts.  You can easily get to the stage where your score is not benefitting much from increased capacity and it is getting hurt a lot by pulls and low average age. BTW you are correct that closing accounts generally hurts your score.  It probably reduces average age, may reduce maximum age, reduces your capacity, and increases your utilization. Closing a credit card decreases your total available balance, which can have a small negative effect if that credit card is a significant portion of your available credit.  If it is not, then it likely will have little impact on your credit in that department. However, the case you explained - get a card, use it for a short while, then dump it - won't have much long-term impact to your available credit, since you will end up with the same amount as you started. The second factor will be the average age of accounts.  This will affect you both in the short and long term, if you've had accounts open for a fairly long time, but won't impact you much if your credit history is fairly short.  Even closed accounts affect the Average Age of Accounts for FICO scores (but not for some other scoring methods such as VantageScore).  If you have only one other account, and it was 10 years old, then opening and closing this decreases your average age of accounts from 10 to 5 years - a significant hit which will not go away for years (10+ years in some cases, though usually 7 years).  This will lower your score some.  If you have had a lot of accounts, though (including things like mortgage, student loan, etc.), this won't have as significant of an impact, and if you had a short history in the first place, it won't hurt you much either. The third factor will be the hard credit pull.  That will have a small negative impact for around six months; so don't do this just before getting a mortgage, but mostly this won't be a significant impactor for you. "The short answer is no, it's probably not ok. The longer answer is, it might be, if you are very disciplined.  You need to make sure that you have enough money to pay off the card after a year, and that you pay the card on time, every month, without exception.  There may also be balance transfer or other fees that only make it worth while if the interest rate or balance on the other loan is high. The problem is most of these offers will raise your rates to very high levels (think 20% or more) if you are even one day late with one payment.  Some of them also will back charge you interest starting from day one, although I have only seen this on store credit ""one year, same as cash"" type offers.   In the end you need to balance the possible payoff against how much it will cost you if you do it wrong.  Remember, the banks are not in the business of lending out free money.  They wouldn't do this unless enough people didn't pay it back in one year for them to make a profit." "I'd say close them if they have fees, if you're worried about fraud or if you're going to be tempted to use them. It may have an affect on your credit rating, but it shouldn't hurt you seriously. Having too many cards gives you the ""opportunity"" to overspend, which obviously isn't good." I should apply for everything I can on the same day, get approved for as many as I can First it may not sound as easy. You may hardly get 2-3 cards and not dozens. Even if you submit the applications the same day; If you still plan this and somehow get too many cards, and draw huge debt, then the Banks can take this seriously and file court case. If Banks are able to establish the intent; this can get constituted as fraud and liable for criminal proceedings. So in short if someone has the money and don't want to pay; the court can attach the wage or other assets and make the person pay. If the intent was fraud one can even be sent to jail. "Ditto Nate Eldredge in many ways, but let me add some other thoughts. BTW there are not four types of account, but five. You're forgetting equity, also called capital. Would it be possible to design an accounting system that does not have 5 types of accounts, maybe is simpler in other ways, and is internally consistent and logical? I'm sure it is. But what's the advantage?  As Nate points out, the existing system has been in use for hundreds of years. Lots of people know how it works and understand it.  I'd add: People have long since worked out how to deal with all the common situations and 99% of the odd cases you're likely to hit. If you invent your own system, you're starting from scratch. You'd have to come up with conventions to handle all sorts of situations. How do I record buying a consumable with cash? How do I record buying a capital asset with credit? How do I record paying off debts? How do I record depreciation? Etc etc. If you worked at it long and hard enough and you're a reasonably bright guy, maybe you could come up with solutions to all the problems. But why?  If you were approaching this saying, ""I see these flaws in the way accounting is done today. I have an idea for a new, better way to do accounting"", I'd say good luck, you have a lot of work ahead of you working out all the details to make a fully functioning system, and then persuading others to use it, but if you really do have a better idea, maybe you can revolutionize the world of accounting. But, ""The present system is too much trouble and I don't want to bother to learn it"" ... I think that's a mistake. The work involved in inventing your own system is going to end up being way more than what it would take to learn the existing system. As to, Aren't liabilities a lot like assets? Well, in a sense I suppose. A credit card is like a checking account in that you can use it to pay for things. But they're very different, too. From an accounting point of view, with a checking account you buy something and then the money is gone, so there's one transaction: reduce cash and increase office supplies or whatever. But with a credit card there has to be a second transaction, when you pay off the charge: So, step 1, increase debt and increase office supplies; step 2, decrease debt and decrease cash. Credit cards charge interest, well you don't pay interest to use your own cash. Etc. One of the beauties of double-entry book-keeping is that every transaction involves a debit and a credit of equal amounts (or a set of debits and credits where the total of the debits equals the total of the credits). If you combine assets and liabilities into, whatever you call it, ""balance accounts"" say, then some transactions would involve a matching debit and credit while others would involve a positive debit and a matching negative debit and no credit. I'm sure you could make such a system work, but one of the neat built-in protections against error is lost. There's a very logical distinction between things that you have or that others owe you, and things that you owe to others. It makes a lot of sense to want to list them separately and manage them separately. I think you'd pretty quickly find yourself saying, ""well, we have two types of balance accounts, those that represent things we have and which normally have positive balances, which we list on chart A, and those that represent things we owe and which normally have negative balances, which we list on chart B"". And before you know it you've just reinvented assets and liabilities." "You should never close a credit card account unless it has an annual fee or you are overspending on it. Open lines of credit - even un-utilized ones - have a positive effect on your credit score. First of all, they increase your total credit which helps your score. Second of all, they are always ""paid on-time"" which is another benefit. Finally, they increase the length of your credit history. You can keep unused credit cards forever in your drawer. They are rarely closed due to inactivity and cost you nothing. However, if your card has an annual fee, you should close it. The potential loss to your credit score is unlikely to offset the annual fee." I have a fair number of cards floating around some reasons I have opened multiple accounts. I am not saying that it is for everyone but there are valid scenarios where multiple credit cards can make sense. You want to have 2-4 credit cards, with a credit utilization ratio below 30%.  If you only have 2 cards, closing 1 would reduce your credit diversity and thus lower your credit score.  You also want at least 2 years credit history, so closing an older credit card may shorten your credit history, again lowering your credit score.  You want to keep around at least 1-2 older cards, even if they are not the best. You have 4 cards: But having 2-4 cards (you have 4) means you can add a 5th, and then cancel one down to 4, or cancel one down to 3 and then add a 4th, for little net effect.  Still, there will be effect, as you have decreased the age of your credit, and you have opened new credit (always a ding to your score). Do you have installment loans (cars), you mention a new mortgage, so you need to wait about 3 months after the most recent credit activity to let the effects of that change settle. You want both spouses to have separate credit cards, and that will increase the total available to 4-8.  That would allow you to increase the number of benefits available. You mentioned you have a bunch of credit cards with no balance, while others have fairly high balances I would not recommend you to close the 0 balance credit cards if they have lower APR. You can transfer the balance to those cards with lower APR. Now, if those 0 balance cards do not have lower APR, closing them will reduce my overall balance and hurt my credit rating and that is true, assume that you mean overall credit line instead of overall balance. But to my understanding, if you keep the payments good and on time, that effect is only temporary, and therefore you can definitely close them.  Don't forget, paying off your balance can also lower your utilization rate and therefore increase your credit ratings, and you can focus more on that instead. Also larger number of accounts with amounts owed can indicate higher risk of over-extension, therefore you should pay off your low balance accounts first, and do not open new credit accounts until you have paid off the current balance.
