Optimal number of credit cards for a given length of credit history
I have found that between the Discover card and a Visa/Master Card a person has everything covered. In my case the Discover card had the best deal (cash back) and the Visa/Master Card took care of those times a vendor didn't take Discover. One big Box store (Costco) did trip us up, so we did end up getting an American Express card. But Costco is dropping that requirement in 2016. One advantage of only having a few cards is that the increase in your total credit line will be split among fewer cards. In your question the highest  max limit on one card is $2500, what will you do if you have to take a flight at the last minute and the Airline ticket is more than that? If you need a higher limit, ask for one of your existing cards to raise it; don't go out and get another card. If you see that one of the companies that you already have a card with has a better card, you can ask them to convert your account to that better card.  Yes higher total limit does help your utilization ratio portion of the score. But there is some opinion that they also look at the utilization ratio per card. So hitting one card to nearly the max can hurt your score. Three caveats about the number of cards:
"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." There is almost no reason to get a second credit card - this is a very good arrangement for your creditor but not for you. Credit cards have high rates of interest which you have to pay unless you pay the credit off every month. Therefore, increasing your total credit capacity should not be your concern.  Since internet technology lets you pay off your balance in minutes online, there is no reason to have multiple cards in order to avoid running out of a balance. If, on the other hand, you do not pay your existing card off every month, than getting another card can be even more dangerous, since you're increasing the amount of debt you take on. I'd say at most it would make sense for you to grab a basic VISA, since most places do not accept AMEX. I would also considering cancelling the AMEX if you get the VISA, for reasons above. The biggest reason that they are a bad idea is just because every credit application hurts your credit score, as does having too many cards. In addition, every new card is a greater risk of identity theft. "FICO SCORING http://www.pbs.org/wgbh/pages/frontline/shows/credit/art/chart_fico.gif This is from the PBS Frontline show ""Secret History of the Credit Card."" Getting rid of one card won't immediately trash your score, nor will it be by the full impact (15%) of credit history. If there's no fee, I'd buy gas once per quarter with it. If there is a fee, I'd check my FICO score and if I can afford to lose 20 or so points for a time, I'd go for it." Ditto to Victor. The simple rule is: Pay the minimums on all so you don't get any late fees, etc, then pay off the highest interest rate loan first. A couple of special cases do come to mind: If one or more of these are credit cards, then, here in the U.S. at least, credit cards charge you interest on the average daily balance, unless you pay off the balance entirely, in which case you pay zero interest. So for example say you had two credit cards, both with 1% per month interest, with debt of $2000 and $1000. You have $1500 available. Ignoring minimum payments for the moment, if you put that $1500 against the larger balance, you would still pay interest on the full amount for the current month, or $30. But if you paid off the smaller and put the difference against the larger, then your interest for the current month would be only $15. (Either way, your interest for NEXT month would be the same -- 1% of the $1500 remaining balance or $15 -- assuming you couldn't pay off the other card.)  If one or more of the loans are mortgage loans on which you are paying mortgage insurance, then when you get the balance below a certain point -- usually 80% of the original loan amount -- you no longer have to pay mortgage insurance premiums. Thus the amount you are paying on such premiums needs to be factored into the calculation. There may be other special cases. Those are the ones that I've run into. I don't know of any and it is unlikely that you will be able to find one.  Most credit card processors charge a flat fee plus percentage.  The flat fee is typically in the 35 cent range making the cost of doing business, in the manner you are suggesting, astronomical.   Also what you are suggesting is contrary to best practices as hosting services, and many other industries, offer deep discounts when making a single payment for an extended period of time. This is not very helpful, but I think it is unrealistic to find what you are suggesting. You can do this if you merge Credit Cards with personal loans. You will have to pay 1 upfront fee but you can bounce a balance between 4 CCs almost indefinitely if you do it right. You have to have good credit though. 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 think you are interpreting their recommended numbers incorrectly.  They are not suggesting that you get 13-21 credit cards, they are saying that your score could get 13-21 points higher based on having a large number of credit cards and loans. Unfortunately, the exact formula for calculating your credit score is not known, so its hard to directly answer the question.  But I wouldn't go opening 22+ credit cards just to get this part of the number higher! "Aside from an annual fee, if any, the card issuer makes money 2 ways, the transaction fee, about 1.5%-2% charged to the merchant, and interest from you if you leave a balance month to month. Obviously, the bank has some cost in processing statements and maintaining your account. If up front you are saying you will not have any chance of providing a certain profit level, they may have no interest in your business. (As you updated.) Other card issuers (almost surely with fees) might. Put the cards on ice. A bag of water in freezer. Don't be so hasty that you ding your report this way. By trashing the history as well as utilization, you may impact your score enough to do some harm if you actually need credit in the near future. I know this is a game with the credit agencies, a ""how good a borrower am I"" game, but it can really impact your bottom line if you don't play along.  In reply to Michael's comment 1/5/15, if I have one card and am budgeted for $1000/mo in spending, in order to keep utilization down to less than 20%, I'd need a line of more than $5000. Even if I ignore utilization, my January spending is $1000, but the bill is cut on the 31st and not due till Feb 25th. So a line of nearly $2000 is required unless you wish to make mid cycle payments on an ongoing basis." "I'm not sure that OP was asking if he/she personally should have more available credit, so I will answer the other interpretation: should that particular card have a higher limit? The answer is ""no.""  The range varies vastly by issuer.  Starting limits vary widely from issuer to issuer even with identical credit histories.  Some issuers never automatically increase the limit, some periodically conduct account reviews to determine if an increase is warranted.  Some like to see higher spending habits each month.  Personally, my cards range from $500 to $25000, and the high and low extremes are the same age. You can search for tips on how often to request increases for your particular card, or what kind of spending habits the issuer prefers.  An important note: You do not need to carry a balance to make the issuer happy.  You never need to pay a cent in credit card interest." Your credit score is definitely affected by the age of your credit accounts, so if you frequently close one card and open another new one, you're adversely affecting the overall average age of accounts.  This is something to consider and whether it is worth what you're trying to achieve. Sometimes, if you're a good customer and are insistent enough, you can simply call your credit card company and use the threat of closing your account in favor of another card that offers something attractive to get your current bank to sweeten its incentives to keep your business.  I know many people who've done this with real success, and they spare themselves the hassle of obtaining a new card and suffering the short term consequences on their credit report.  This might be an avenue worth trying before you just close the account and move on. I hope this helps. Good luck! 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. "Several events will always result in a reduction of your score, including: These will show up in the short term, but I don't think it's worth $40 per year in perpetuity to avoid this. These aren't serious ""black marks"" in the same category as missing payments, carrying too much debt, or foreclosures/evictions, etc. These effects are designed to signal issuers when someone acquires a large amount of credit in a very short period of time, which may indicate a greater risk. If your credit is good and you are using your other cards responsibly, closing the card (given the annual fee) would not cause me great concern if it were me. Since you are so much better of a risk than you likely were in college, you can also call Capital One, ask to speak with a supervisor, and ask them to drop the fee and increase your credit limit. They should be able to easily verify that you meet the requirements for other types of preferred cards they offer, and they should be willing to offer you improved terms rather than losing your business. It is very possible they simply haven't re-evaluated your risk since you initially applied. Also, remember that these types of effects determine only a portion of your overall score. Activity is also a major component. Rather than leaving an unused card open for history and debt-to-limit purposes only, I would also recommend having some minimum level of activity, such as an automatic bill payment, on each card you carry. The effect of using your cards over time will have a significant positive effect on your score. Best of luck!" Incredible article, tons of data. Thank you!   It does answer the above posters question if you're willing to read through. It provides data with and without 'revolving debt'.  Side note; interesting to see how age and income trend. Debt increasing during the family-middle aged years, and during the peak income earning years.  I'd say you want these credit card debt lower overall and on average; but with the distribution it may be sustainable.
