Will a Barclaycard Visa help me in building up credit score?
Payment history is probably the most significant contributor to your credit score.  Having a solid history of making, at least the minimum, payments on time will have a positive impact on your credit score.  Whether or not this specific transaction means anything to that equation is up for debate.   If you have no credit lines now and 0% for 18 months on a computer makes sense to you, then yes, making this purchase this way and paying on time will have a positive impact on your credit score.  Paying interest doesn't help your credit score.  Repay this computer before the 18 month period ends, then be sure to pay your balance in full every month thereafter.
I plan to stay debt free, but I appreciate the non-debt-related advantages of having a good credit score. If you plan to stay debt-free, then opening up more cards will not significantly change your credit score.  You seem to want to be going from a good score to a great score, which adding cards alone will not do.   Also, I highly doubt it will significantly affect any of the five things you mention.  If you had a bad credit score, then I could see some effect on renting an apartment, getting a job (where trust with money is a component of the job), etc., but don't try to game the system for some number. You won't magically get cheaper cell phone rates, lower insurance premiums, etc. If you can set up automatic payments (like direct debits in the UK) and you can be disciplined enough to not spend the money on something else then this can be a good way of building/improving your credit rating. Banks / Lenders like it when they see you have previously taken, and repaid, credit. This can help you get better finance deals etc. in the future. Update: as noted in the comments France had a different financial system and people do not have credit ratings, so this point isn't valid in France Not only should you do this, you should tell your friends to do it too. Especially if a parent comes in to the bank with the child, banks fall over themselves to provide a card to someone whose only income is allowance. Really. Later, if you're 21 and your car broke and you don't get paid for another 11 days, NOBODY will lend you the money (or those money mart places that charge 300% a year will) to fix it. Never mind score (and yes for sure having a good score will be a result, and a good one) just having the card for emergencies makes all the difference to your early twenties. My kids have several friends who now can't get credit cards (some are students, some are underemployed) and end up missing paid days of work due to car troubles they can't pay to fix, or using those payday lenders, or other things that keep you poor. Get one while you can. Using it sensibly means you will have a great credit score in a decade or so, but just plain having it is worth more than you can know if you're not 18 yet. First, you need to be aware that the credit score reported by Mint is Equifax Credit Score. Equifax Credit Score, like FICO, Vantagescore, and others, is based on a proprietary formula that is not publicly available.  Every score is calculated with a different formula, and can vary from each other widely.  Lenders almost exclusively only use FICO scores, so the score number you have is likely different than the score lenders will use. Second, understand that the advice you see from places like Mint and Credit Karma will almost always tell you that you don't have enough credit card accounts.  The reason for this is that they make their money by referring customers to credit card applications.  They have a financial interest in telling you that you need more credit cards. Finally, realize that credit score is just a number, and is only useful for a limited number of things.  Higher is better to a point, and after that, you get no benefit from increasing your score.   My advice to you is this: Don't stress out about your credit score, especially a free score reported by Credit Karma or Mint.  If you really have a desire to find out your score, you can pay FICO to get your actual score, but it's not cheap.  You can also sometimes get your FICO score by applying for a loan and asking the lender.  I last saw my FICO scores (there were three, one from each credit bureau) when I applied for a mortgage a couple of years ago, and the mortgage rep gave them to me for free.  But honestly, knowing your score doesn't do much for you, as the best way to increase it is to simply make your payments on time and wait. Don't give in to bad conventional advice from places that are funded by the financial services industry.  The thing that makes your credit score go up is a long history of paying your bills on time.  Despite what you commonly read about credit scores, I'm not convinced that you can radically boost your scores by having lots of open credit card accounts.  At the time I applied for my last mortgage, I only had 2 open credit cards (still true), and the oldest open account was about 1.5 years old.  The average of my 3 scores was just over 800.  But I've been paying my bills on time for at least 20 years now.  Only get credit cards that you actually want, and close the ones you don't want. 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! "It appears that you already know this, but FICO credit scores (as controlled by Fair Isaac Corporation) are the real official credit scores, and FICO takes a cut on their production no matter which of the 3 major credit bureaus calculates the official score (all using slightly different methods). Be careful when obtaining a score for making a big decision that it is a FICO score, because relatively few lenders will lend based on a non-FICO score. That said, some non-FICO scores are easy to obtain and can be roughly translated to an approximation of your score. Barclays US/ Juniper Bank credit cards offer a free Transunion ""TransRisk""(TM) score. The TransRisk score is a 900 point scale, while the FICO score is an 850 point scale. This is a simple ratio and you can calculate your approximate FICO score by the formula:" The length of time you have established credit does improve your credit score in the long run. As long as you can avoid paying interest, you might see if you can get a card with cash back rewards. I have one from Citi that sends me a $50 check every so often when I have enough rewards built up. IIRC it's not a FICO score, as mentioned here, too. That said, apart from borrowing money to optimise your credit score as a hobby, my understanding is that once you're above a FICO score of 750, it pretty much doesn't matter how close to 800 you get. "A credit card is a way to borrow money. That's all. Sometimes the loans are very small - $5 - and sometimes they are larger. You can have a credit card with a company (bank or whatever) that you have no other relationship with. They're not a property of a bank account, they are their own thing. The card you describe sounds exactly like a debit card here, and you can treat your Canadian debit card like your French credit card - you pay for things directly from your bank account, assuming the money is in there. In Canada, many small stores take debit but not credit, so do be sure to get a debit card and not only a credit card. Now as to your specific concerns. You aren't going to ""forget to make a wire."" You're going to get a bill - perhaps a paper one, perhaps an email - and it will say ""here is everything you charged on your credit card this month"" along with a date, which will be perhaps 21 days from the statement date, not the date you used the card. Pay the entire balance (not just the minimum payment) by that date and you'll pay no interest. The bill date will be a specific date each month (eg the 23rd) so you can set yourself a reminder to check and pay your bill once a month. Building a credit history has value if you want to borrow a larger amount of money to buy a car or a house, or to start a business. Unlike the US, it doesn't really have an impact on things like getting a job. If you use your card for groceries, you use it enough, no worries. In 5 years it is nice to look back and see ""never paid late; mostly paid the entire amount each month; never went over limit; never went into collections"" and so on. In my experience you can tell they like you because they keep raising your limit without you asking them to. If you want to buy a $2500 item and your credit limit is $1500 you could prepay $1000 onto the credit card and then use it. Or you could tell the vendor you'd rather use your debit card. Or you could pay $1500 on the credit card and then rest with your debit card. Lots of options. In my experience once you get up to that kind of money they'd rather not use a credit card because of the merchant fees they pay." I would say you are typical.  The way people are able to build their available credit, then subsequently build their average balances is buy building their credit score.  According to FICO your credit score is made up as follows: Given that you had no history, and only new credit you are pretty much lacking in all areas.  What the typical person does, is get a card, pay on it for 6 months and assuming good history will either get an automatic bump; or, they can request a credit limit increase. Credit score has nothing to do with wealth or income.  So even if you had 100K in the bank you would likely still be facing the same issue.  The bank that holds the money might make an exception. It is very easy to see how a college student can build to 2000 or more.  They start out with a $200 balance to a department store and in about 6 months they get a real CC with a 500 balance and one to a second department store.  Given at least a decent payment history, that limit could easily increase above 2500 and there could be more then one card open.   Along the lines of what littleadv says, the companies even welcome some late payments.  The fees are more lucrative and they can bump the interest rate.  All is good as long as the payments are made. Getting students and children involved with credit cards is a goal of the industry.  They can obtain an emotional attachment that goes beyond good business reasoning. When you start living in US, it doesn't actually matter what was your Credit history in another country. Your Credit History in US is tied to your SSN (Social Security Number), which will be awarded once you are in the country legally and apply for it. Getting an SSN also doesn't guarantee you nothing and you have to build your credit history slowly. Opening a Checking or Savings account will not help you in building a credit history. You need to have some type of Credit Account (credit card, car loan, mortgage etc.) linked to your SSN to start building your credit history. When you are new to US, you probably won't find any bank that will give you a Credit Card as you have no Credit history. One alternative is to apply for a secured credit card. A secured credit card is one you get by putting money or paying money to a bank and open a Credit Card against that money, thereby the bank can be secure that they won't lose any money. Once you have that, you can use that to build up your credit history slowly and once you have a good credit history and score, apply for regular Credit Card or apply for a car loan, mortgage etc. When I came to US 8 years ago, my Credit History was nothing, even though I had pretty good balance and credit history back in my country. I applied for secured credit card by paying $500 to a bank ( which got acquired by CapitalOne ), got it approved and used it for everything, for three years. I applied for other cards in the mean time but got rejected every time. Finally got approved for a regular credit card after three years and in one year added a mortgage and car loan, which helped me to get a decent score now. And Yes, a good Credit Score is important and essential for renting an apartment, leasing a car, getting a Credit Card etc.  but normally your employer can always arrange for an apartment given your situation or you need to share apartment with someone else. You can rent a car without and credit score, but need a valid US / International Drivers license and a Credit Card :-) Best option will be to open a secured credit card and start building your credit. When your wife and family arrives, they also will be assigned individual SSN and can start building their credit history themselves. Please keep in mind that Credit Score and Credit History is always individual here... No, it will have no negative impact on getting a mortgage. You are building up a history with regular payments and are not carrying a balance on the card each month. Your ability to get a mortgage will ultimately be based on other things. Money Saving Expert has a good guide on what will affect your credit score. A further discussion on the topic that backs up that what a mortgage company is interested in is affordability and a stable history. They really don't care about utilisation ratios.  (Though might be spooked by almost maxed out cards - sign of poor spending control, or large unused limits - too easy to go into bad debt.) "In the other question, the OP had posted a screenshot (circa 2010) from Transunion with suggestions on how to improve the OP's credit score.  One of these suggestions was to obtain ""retail revolving accounts.""  By this, they are referring to credit accounts from a particular retail store.  Stores have been offering credit accounts for many years, and today, this usually takes the form of a store credit card.  The credit card does not have the Visa or MasterCard logo on it, and is only valid at that particular store.  (For example, Target has their own credit card that only works at Target stores.)  The ""revolving"" part simply means that it is an open account that you can continue to make new charges and pay off, as opposed to a fixed retail financing loan (such as you might get at a high-end furniture store, where you obtain a loan for a single piece of furniture, and when it is paid off, the account is closed). The formula for credit scores are proprietary secrets.  However, I haven't read anything that indicates that a store credit card helps your credit score more than a standard credit card.  I suspect that Transunion was offering this tip in an attempt to give the consumer more ideas of how to add credit cards to their account that the consumer might not have thought of.  But it is possible that buried deep in the credit score formula, there is something in there that gives you a higher score if you have a store credit card. As an aside, the OP in the other question had a credit score of 766 and was trying to make it higher.  In my opinion, this is pointless.  Remember that the financial services industry has an incentive to sell you as much debt as possible, and so all of their advice will point to you getting more credit accounts and getting more in debt." "Credit Unions have long advocated their services based on the fact that they consider your ""character.""  Unfortunately, they are then at a loss to explain how they determine the value of your character, other than to say that you're buddies & play pool together so they'll give you a loan. Your Credit History / Score is as accurate a representation of your character in business dealings as can be meaningfully quantified.  It tracks your ability to effectively use and manage debt, and your propensity to pay it back responsibly or default on obligations.  While it isn't perfect, it is certainly one of the best means currently available for determining someone's trustworthiness when it comes to financial matters." FICO is a financial services company, whose customers are financial services companies.  Their products are for the benefit of their customers, not consumers. The purpose of the credit score system is two-fold.  First, the credit score is intended to make it easy for lending institutions (FICO's customers) to assess the risk of loans that they make.  This is probably based on science, although the FICO studies and even the FICO score formula are proprietary secrets. The second purpose of the credit score is to incentivize consumers into borrowing money.  And they have done a great job of that.  If you think you might need a loan in the future, perhaps a mortgage or a car loan, you need a credit score.  And the only way to get a credit score is to start borrowing money now that you don't need.   Yes, someone with a good income and a long history of paying utility bills on time would be a great credit risk for a mortgage.  However, that person will have no credit score, and therefore be declared by FICO as a bad credit risk.  On the other hand, someone with a low income, who struggles, but succeeds, to make the minimum payment on their credit card, would have a better credit score.  The advice offered to the first person is start borrowing money now, even though you don't need it. I'm not anti-credit card.  I use a credit card responsibly, paying it off in full every month.  I use it for the convenience.  I don't worry at all about my credit score, but I've been told it is great.  However, there are some people that cannot use a credit card responsibly.  The temptation is too great.  Perhaps they are like problem gamblers, I don't know.  But FICO and the financial services industry have created a system that makes a credit card a necessity in many ways.  These are the people that get hurt in the current system.
