Should I close unused credit cards before applying for another?
If you're looking for cause-effect, applying for another card won't matter at all if you're not paying any interest, or not looking to get another installment loan for which the rate you get depends on your credit rating. If you are looking to get another installment loan, then having more credit at your disposal might hurt a small amount.  I wouldn't want to cancel your oldest card.  The GEMB card looks like a good candidate if you want to cancel because you're not using it, and it's a relatively new card. 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.
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. I disagree with the reply.   Your both impressions are correct. -   Do not close old credit cards because they keep your credit rating high (fico score) -   Also low utilization that credit cards report to credit rating companies, improves your rating. The difference in interest is not a huge factor in your decision.  It's about $2 per month.   Personally I would go ahead and knock one out since it's one less to worry about.  Then I would cancel the account and cut that card up so you are not tempted to use it again. To address the comments... Cutting up the card is NOT the ultimate solution.  The solution is to stop borrowing money... Get on a strict budget, live on less than what you bring home, and throw everything you can at this high-interest debt.   The destroying of the card is partly symbolic - it's a gesture to indicate that you're not going to use credit cards at all, or at least until they can be used responsibly, not paying a DIME of interest.  It's analogous to a recovering alcoholic pouring out bottles of booze.  Sure you can easily get more, but it's a commitment to changing your attitude and behavior. Yes leaving the card open will reduce utilization and improve (or not hurt) credit score - but if the goal is to stop borrowing money and pay off the other card, then once that is achieved, your credit score will be significantly improved, and the cancelling of the first card will not matter.  The card (really both cards) should never, ever be used again. You don't need to use an open line of credit to help your credit score. You didn't ask this, but another option is to not cut up the card and keep the account open, even if you don't use it. I mention this because sometimes when you are calling in or setting up an online account to service the card, you may need to have the expiration date and CVV code on hand. This has burned me a few times as I had to hunt around for a card I rarely ever use. That being said, if you are worried that you might use the card if you know it's there, then sure, cut it up. "In the sole interest of improving your credit score, the thing you should focus on is lowering your overall utilization. The best thing you could do for this would be to get a loan to reconsolidate your credit card debts into a single, long term loan. The impact of this is that your credit card utilization, assuming the loan covers 100% of your balances, will suddenly drop to 0%, as you'll no longer have a balance on the cards. Additionally, at this point, with a consolidation loan, you'll be building loan history by making steady, fixed payments on the loan.  The loan will also, ideally, have a significantly lower interest rate than the cards, and thus will save you money that you'd otherwise be spending on interest.  A lot of others here will feed you some additonal, irrelevant advice - ""Pay off X credit card first!""; Ideally, you need to eliminate this debt. But to directly address the question of how you could improve your credit score, based on your utilization, I believe the best option would be for you to reconsolidate your credit card debt into a single loan, to reduce your utilization on the cards." If you've got the money to pay off your credit cards, do it. Today, if possible. There is no need to pay another penny of interest to them.  They may or may not cancel your cards. That is up to them. We can't know what will trigger an individual bank to cancel your card. The answers you got on your other question offer some speculation on why some banks might cancel, but this is not something banks reveal. Anything you do on your own to try to keep the cards open is just a guess, and may or may not succeed.  But ask yourself: why do you want to keep these cards?  Is it for the convenience of the card? I agree that credit cards (paid in full monthly) are convenient, but when they start costing you money, they aren't worth it anymore, in my opinion. Debit cards have most of the same conveniences of credit cards, and are free.  If it is for emergencies, I recommend instead building up an emergency cash fund. That way, if an emergency arises, you won't be forced to borrow money at high credit card interest rates.  If the reason you want to hang on to the credit card is so you can spend more than you have, then you will find yourself in the same situation again. If I were you, I would pay off the cards ASAP. If the banks cancel your cards, just switch to a debit card and be thankful that you are no longer continuously leaking money to the banks. 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. "The only good reason I find to close cards are: it's a card with an annual fee that you don't need.  No point bleeding money each year. churning rewards.  Open card to get bonus promotion such as ""spend $500 in first 3 months, get $200 bonus"".  Close card and open a year later to do that same bonus again if available.  Many cards don't allow you to do this. making room for newer cards at the same bank.  Example, you have 5 Chase Cards and you want to apply for a 6th.  Chase says you have maximized your credit they will extend you.  You close one of your existing cards to get that new card. I have seen that many banks allow you to shift over some over your existing available credit to your new card without having to close them." In your specific case, I would leave them open unless you have a specific reason for wanting to close them - particularly, unless you feel closing them is necessary for you to not misuse them. The impact on the credit score is not why I say this, though.  Much more important are the two competing real factors: My suggestion would be to take the cards and put them in your file cabinet, or whatever would cause you to not use them.  In fact, you could even cut them up but not close the accounts - I had an account open that I didn't possess a physical card for several years for and didn't use at all, and it stayed open (though it's not guaranteed they'll keep it open for you if you never use it).   In an emergency you could then ask them to send you a new copy of the card very easily.  But, keep them, just in case you need them. Once you have paid off your balances on your balance-carrying cards, then you should consider closing some of them.  Keep enough to be able to live for ~4-6 months (a similar amount to the ideal rainy day fund in savings, basically) and then close others, particularly if you can do so in a way that keeps your average account age reasonably stable. 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. pay off one of the cards completely. there are several reasons why: "There are two factors in your credit score that may be affected. The first is payment history. Lenders like to see that you pay your bills, which is the most straightforward part of credit scores IMO. If you've actually been paying your bills on time, though, then this should still be fine. The second factor is the average age of your open accounts. Longer is considered better here because it means you have a history of paying your bills, and you aren't applying for a bunch of credit recently (in which case you may be taking on too much and will have difficulties paying them). If this card is closed, then it will no longer count for this calculation. If you don't have any other open credit accounts, then that means as soon as you open another one, your average age will be one day, and it will take a long time to get it to ""good"" levels; if you have other matured accounts, then those will balance out any new accounts so you don't get hit as much. Incidentally, this is one of the reasons why it's good to get cards without yearly fees, because you can keep them open for a long time even if you switch to using a different card primarily." Closing your oldest revolving account will lower your average age of accounts and hurt your score.  No ifs, ands, or buts.  The amount it drops is hard to tell, and it may only be a few points if your other cards are fairly old as well. While the FICO scoring algorithm is proprietary and hard to predict, you can use the official FICO Simulator to estimate the impact.  Based on the information you provided (5+ cards, oldest card 5 years), your estimate is 750-800.  Performing the same estimate and only changing the number of cards and age (2-4 cards, oldest card 2-4 years), the score estimate drops to 735-785.  Both of these estimates assume you have 9% or less utilization.  You can probably estimate that your score will drop at least 15 points. However, it may not matter to you whether your score is maximized.  Once you get above a certain FICO score, it doesn't matter.  For example, I recently refinanced a vehicle and asked the loan officer about their lowest APR, and found out that they required a 780 FICO for it.  Kind of like the difference between getting a 91 or a 99 in a class, an A is an A. Some other factors you may want to consider before you make your choice: Also, unless I missed it and someone already mentioned it, do keep in mind the impact of these credit cards balances on your credit score. Over roughly 75% usage on a given credit account reflects badly on your score and has a pretty large impact on how your worthiness is calculated. It gives the impression that you are a person that lives month to month on cards, etc. If you could get both cards down to reasonable balances to where you could begin paying on them regularly and work them down over time, that will not only look incredible for your credit report but also immediately begin making your credit worthiness begin to raise due to the fact that you will not have accounts that (I'm assuming here) are at very high usage (over 75% of your total limit.) If you have to get one card knocked out just to get breathing room, and you're boxed in here -- or honestly even if the mental stress is causing you incredible hardship day to day, then I suppose blow one card out of the water, reassess and start getting to work on that second card. I hope this helped, I'm no expert, but I have had every kind of luck with credit cards and accounts you could think of, so I can only give my experience from the rubber-meets-the-road perspective. Good luck! Except for the fact that canceling credit cards will hurt your credit, either by increasing your utilization ratio or decreasing the length of your credit lines if you cancel the oldest card, which makes it that much harder to get the good interest rates available on other loans.
