Most of this information is based on credit cards issued by financial institutions (banks, companies) in the United States. However, I've used cards all over the world and have found the experience to be very standardized.
My First Credit Card
I applied for my first credit card in 2007 as a sophomore in college. Up until that point, I had used my debit card for all my online and many in person transactions. I read online about getting reward points for purchases and I thought that could be a good way to make some extra cash.
I applied for an American Express Blue card, mostly because I thought AMEX was the most badass of cards. My grandfather, one of my heroes, is always rocking the AMEX Platinum. I wanted to be as cool as him.
I eventually got a USAA credit card as well in 2008, because they use the MasterCard network, which was accepted more places than the American Express. Since 2008 I've opened and closed several credit card accounts with Citi, Chase, and USAA.
I've used Visa, MasterCard, and American Express. I haven't experimented with the Discover network, but I heard good things about it. I closed the original AMEX I got because I didn't understand the value of the rewards program. I've kept my USAA card account open but don't use it for anything but paying my USAA automobile insurance.
Because the USAA card is now my oldest credit line, I'll probably keep it open until the end of time, so that it increases the average age of my accounts. (Average age of accounts is 15% of your credit score).
Most importantly though, I have never accumulated any credit card debt. The credit card companies and banks that issue me my cards have never received a dime in interest, late fees, finance charges, or any other fee from me. It's really easy to do, I'll show you how:
Credit Cards Are Not Rocket Science
I think a lot of people make credit cards harder than they have to be. Credit cards are a way for you to easily pay for goods and services, online, over the phone, or in person. (I guess by mail too, if that's still a thing.) They are known in the industry as a “revolving line of credit.”
Every credit card (except a very few) have a credit limit. This is the amount of money the card issuer trusts you with. For some students starting out, the limit may be as low as $500. For Wall Street bankers, they might have access to $100,000. At one point, as an unemployed college student, my American Express limit was $18,000. Pretty crazy when I only had $800 to my name.
Credit cards also come with interest rates attached to them. This scares a lot of people, but you have to realize: if you do it right, you'll never even know what your interest rate is. Keep reading to find out why.
Credit Cards vs. Debit Cards
Debit cards deduct money from your checking account. They are almost the same as cash. That's it. Simple. No bills, no statements, no delayed payments. You can only spend what is in the account linked to your debit card.
Credit cards are only limited by the credit limit. So I could have spent $18,000 on a ski trip to Whistler if I had been real dumb in college. Fortunately for me, I wasn't.
Minimum due vs Statement Balance vs Current Balance
Credit cards have a predetermined length of time until a statement or bill is generated. Usually this is four weeks or a month. At this point, all of the transactions that occurred from, say, Jan 1-Feb 2 are tallied up and presented to the card holder (you). You usually have 21 or so days from the time the bill is sent to you to pay the bill. You'll generally be presented with three payment options: minimum due, statement balance, and current balance.
This is the dangerous one. Remember that interest rate I mentioned earlier? If you pay this amount, anything that you leave unpaid will start accumulating interest. This is how people get into trouble with credit cards. They only make the minimum payments, which can be as low as $25 per month, while ignoring the fact that they have $1000s of unpaid balance that is now accumulating the insanely high interest rates credit cards come with. If you're smart and don't want to pay the credit card companies anything: DO NOT JUST MAKE MINIMUM PAYMENTS.
This is the sum of all of your transactions during your billing cycle. So for instance, your billing cycle may run from the 15th of January to the 15th of February. If you had 10 transactions totaling $100 during that time, your minimum payment would probably be $15, and your statement balance would be $100.
You'll receive your bill usually a few days after your billing cycle closes, so let's say you get it on 18 February. Now, you'll usually have 3 weeks to make your payment, so it will be due around 11 March. All of this information will be on your statement. In order to pay off your card and accumulate no interest charges, simply pay your statement balance before the due date. Easy. Done. This will pay for all of your transactions on that bill. Since you'll probably still be using your card though, you may sill have a balance, which brings us to…
This is the sum total of all transactions that haven't been paid yet. It's usually equal to or greater than your statement balance. So for instance, if you had the $100 for 15 Jan to 15 Feb, and then you spent another $50 on 16 Feb, your current balance would be $150. To be extra cautious, you can simply pay your current balance at any time and you will be so far removed from interest charges you'll never even think about them. I always pay my current balance. It's just easier.
Pending Charges on Credit Card
Possibly the most annoying thing about credit cards is the pending charges. Because of the way the processing network is setup, credit card transactions often take 2-3 business days to process. That means that you could look at your current balance and see $0, while there's $1000 in pending charges waiting to be processed. Annoying!
One way to get around this is to look at your pending charges, which will be listed online for most credit cards. Another way is to look at your available credit limit. This is updated almost instantaneously to reflect pending charges. So if your current balance is $0, your limit is $1000, but your available limit is $800, you probably have $200 in pending charges. Remember that so you don't go spending money you don't have!
This is how I get around this problem: Any time I make a credit card transaction, I move that amount of money from my main checking account to my “bills” account. That way when I look at my main checking account, I've already deducted the pending credit card charges. Then, every week or so, I pay off my current balance on all my credit cards from my bills account. My credit card balance goes to $0, I know I have the money to pay them in my bills account, my credit card reward points keep increasing, the credit card companies get their little slice of profits, and everyone is happy.
How to Get Your First Credit Card
Getting your first credit card is often too easy. As a student or military servicemember, you're often a target demographic of the credit card companies. American Express offers military servicemembers no annual fees on all of their cards. I keep a list updated monthly of the best credit card offers I've found.
I'd recommend a student card if you are in college or a secured card if you're not. Only charge a few things to it a month and pay it in full every month. You will build yourself a great credit history and thank yourself later for not going into heaps of credit card debt.
