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.
First, before we talk about anything having to do with the credit score, we need the disclaimer that the exact credit score formulas are proprietary secrets that have not been revealed.  Therefore, all we have to go on are broad generalities that FICO has given us. That having been said, the credit card debt utilization portion of your score generally has at least two components: an overall utilization, and a per-card utilization. Your overall utilization is taken by adding up all your credit card debt and all your credit limits and dividing.  Using your numbers above, you are sitting at about 95%.  The per-card utilization is the individual utilization of each card.  Your five cards range in utilization from 69% to 100%. Paying one card over another has no affect on your overall utilization, but obviously will change the per-card utilization of the one you pay first.  So, to your question: Is it better on the credit score to have one low-util card and one high-util card, or to have two medium-util cards?  I haven't read anything that definitively answers this question. Here is my advice to you: The big problem you have is the debt, not the credit score.  Your credit card debt should be treated like an emergency that needs to be taken care of as quickly as you possibly can.  Instead of trying to optimize your credit score, you should be trying to minimize the number of days until all of your credit cards are completely paid off.  The credit score will take care of itself once you get your financial situation back on track. There is debate about the order in which one should pay off their debts, but the fact of the matter is that the order is not as significant as the intensity at which you pay them all off.  Dedicate yourself to getting rid of the debts as fast as possible, and it won't matter much which order they get paid off in. Finally, to answer your question, I recommend that you attack the card debt one at a time instead of trying to pay them off evenly.  Not because it will optimize your credit score, but because it will help you focus your debt-reduction energy as you work on resolving your debt emergency.  Fortunately, the credit utilization portion of the credit score has no history, so once you pay all of these off, the utilization portion of your score will get better immediately, and the path you took to get there will be irrelevant. After the credit cards are completely paid off, and you have resolved never to spend money that you don't have again, it is time to work on the student loans.... We are the richest nation in the history of the world. We produce and consume more now than at any point in history.   Credit card debt is nowhere near historical levels. Delinquency rates on credit card loans is near the lowest it has ever been.  https://fred.stlouisfed.org/series/DRCCLACBS   It may seem wild and not make a lot of sense that data does not fit your worldview, but let yourself be open to information that conflicts with your own.   otherwise you are just held hostage by your own misconceptions.   You are going to wait a lifetime for that riot pal and you may learn to capitalize proper nouns while you are at it. I faced something similar for travel or work reasons, and as for me I preferred wire transfer over credit card withdrawals because my bank has huge fees. My thoughts so far are: the fee can vary a lot for credit card. As for me, I can expect 5% fees on foreign withdrawals. But I considered changing bank and I think a Gold (or premium) card might be a good idea as well. The idea is you pay a big subscription (100 euros or so) but have no fee. The total of withdrawal fees could easily (if you stay long abroad) reach this amount. There are also banks like HSBC that offer low fees on withdrawals abroad, you can ask them. The problem is that you cannot really withdraw huge amounts to lower the fee (since you carry this cash in the street). for wire transfers the total fee is usually $50 or more (I had a fee from distant bank, a fee for change and a fee in my home bank). But the amount is unlimited (or high enough to be of little matter) and I needed to do this once per year or so. So I guess it could be interesting if you have enough savings to only transfer money every couple of months or so. I think Western Union is also involved this profitable business. I never used it because the fees are pretty high, but maybe it is useful for not too big amounts frequently transfered. Actually, have you considered a loan? It's a very random idea but maybe you can use a loan as a swap and then transfer money when you have enough to reimburse it all. But the question is very interesting, I think the business is pretty huge due to globalization. It is expensive because some people can make a lot of money out of it. Usually, it's not a good idea as it will not only raise your debt to income ratios,  but also impact your credit scores. However, if you have extensive credit history, having owned a home or two for a while (read: 10-20 years), taken out multiple auto loans in the past and paid them satisfactory, your credit score may not take a big hit. Possibly ust 5-10 points or it can be 30-40 points. It really depends on the depth of your credit profile. Would opening a second credit card contribute in any meaningful way to my credit mix or no, since it's the same type of credit? Yes, multiple lines of credit help your credit score, even if they are all credit cards. There are experts on both sides of this argument though. For example, Fico says that you shouldn't open a new credit card just for the credit boost, while NerdWallet cautiously recommends it. My recommendation is that if you're disciplined with your credit spending, it will help a little. If yes, is it worth it to take the hit to my average account age sooner rather than later by opening a new credit card? If you want to build up your number of credit lines, do so well before you need to use your credit to take out a loan. Not only will your credit score take a hit from the average age dropping, but you'll also have a hard pull on your credit report. As Fixed Point points out, though, you will see a larger improvement to your credit score by adding another type of credit, such as a home loan, to your credit mix. If you are already limited your credit utilization to 10%-30% then you probably won't be able to reach your goal by just adding a credit card. "3 reasons I can think of: I once worked for a bank and when credit scoring for loans, if you had been approved by different institutions, you were given a better score. So if you held a Visa and Mastercard (as opposed to two Visa cards) your credit score would go higher. More than 6 cards though looked suspicious and your score would take a big hit. Having more than card has helped me when getting special offers multiple times from some websites where it was limited to ""one per customer"" though most just used your address or email account. If you owed $1000 in total which you can't pay off in one go, it is better to have that split across two cards. You would be paying interest on $500 on each card but when you have one card paid off, the interest you would be paying on the other would be based on the original debt to that one card of $500 (not $1000). I hope that makes sense." 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! I've had a card cloned 15 years ago and used to buy over 5k of goods in another country. So the inconvenience of having a card closed and re-issued is quite annoying even though the charges were reversed and I was made whole. But these days most CC fraud isn't from a card scanned by a waiter and cloned then used elsewhere. Mostly it is poorly secured databases or point of sale terminal malware. The latter is getting curtailed by chipped cards and the largest source of fraud is now online transactions (so called card not present) where the merchant has your CC number. If their system is breached the bad guys have a wealth of card numbers they sell in an E-bay like site on the dark web. This is where the Citi virtual CC comes in handy. Here's how it works to protect the bank and the hassles you go through when a card as to be re-issued. Citi's virtual CCs let you generate an actual credit card, complete with security code and expiration date. What is unique is that once the virtual CC is used it can only be used subsequently by that same merchant and is declined by any other. You can also set a total limit on what the merchant can charge as well as an expiration date. I use them for all my online accounts because they are, for all practical purposes, immune to the malware that steals CC info. Even if somehow the virtual CC is used before the merchant makes the initial charge that locks in the CC to their account the charge can be reversed without closing your actual card which has a different number. You can manage multiple Citi virtual CCs and view charge status, close, or adjust limits over time so managing them is quite easy with no risk to your primary account.
