When used correctly, credit cards can be an easy ladder to better credit scores and valuable rewards.
But, when used incorrectly, they can be a direct chute to debt and misery.
Whether you’re a total beginner — or a former credit card holder looking to avoid past mistakes — this article will explain how to properly use a credit card in six easy steps.
Credit cards provide a “revolving” line of credit (as opposed to a non-revolving, static loan like a mortgage).
When you apply for a credit card, the bank looks at a number of factors, including your income, debt, and credit history. It’ll then decide whether to extend you a line of credit — and how much of one. This “credit limit” is the maximum amount you can spend on your card before paying some of it off.
Every time you swipe your card — at a store, hotel, restaurant, or website — you’re borrowing money from the card issuer and using more of your credit limit.
How Does a Credit Card Work? Here’s an Easy-to-Understand Guide and Credit Card Definition
At the end of the month, you’ll receive a credit card bill, which will include the following figures:
The most important rule of responsible credit card use is to pay your bill on time. Late payments, which appear on your credit reports, are a red flag to lenders. And paying late means you’ll also owe late fees and interest.
To ensure you pay your credit card bill on time, set up notifications from within your credit card’s online account. For my credit card, I receive an email both when my statement is issued and when my due date is 10 days away.
While there, you can also set up payments to be automatically withdrawn from your checking account each month. This is a smart move if your bills are consistent and you’re nervous about missing payments (but you should check in to make sure they go through). Personally, I prefer to pay manually, as it gives me an opportunity to review the charges and avoid overdrafting my checking account.
How Paying a Credit Card Works: Understanding Your Credit Card Statement
If you’re wondering how to use a credit card wisely, here’s the key.
You probably already know that most credit cards have high interest rates (aka annual percentage rates, or APRs). The average APR is 17%.
What you might not know is that you can avoid paying this interest entirely.
When you receive your first credit card bill, it won’t include any interest charges yet. That’s because almost all credit cards offer an interest-free “grace period” between the date your statement closes and the date your payment’s due. During this period, your purchases will not accrue interest (though cash advances and balance transfers are a different story).
Translation: If you pay the entire statement balance by the due date, you won’t owe any interest on your purchases. If you continue to pay the statement balance in full and on time — each and every month — you’ll never pay any interest at all.
That’s the secret of every smart credit card holder, because you get all of the perks of credit card usage, including security, rewards, and convenience, without paying a dime in interest.
How to Avoid Paying Interest on Credit Cards
Each month, your credit card issuer will probably report your behavior to the three major credit bureaus (most issuers do).
As the bureaus gather information about your credit card use, they will create credit reports for you (if they don’t already have them), which are used to generate credit scores.
Because of this, credit cards are one of the easiest ways to build credit. Making your monthly payments in full and on time will eventually lead to good credit scores, all other things being equal.
Also because of this, you should strive to keep the balance on your credit card low on your statement closing date. Not only does this mean you’ll be able to pay off your balance each month (and thus avoid interest charges), it also means you’ll have a low credit utilization ratio.
This ratio, which represents the percentage of available credit you’re using, is one of the most important factors in your credit scores. You want to keep it as low as possible.
This chart shows the criteria used to create FICO scores and their relative importance in your credit score.
If you have a $1,000 limit on your credit card, and you’re carrying a $700 balance at the statement closing date, you’re using 70% of your available credit. That’s not a good look to creditors.
But if you have a $1,000 limit and a credit card balance of $200, your utilization is only 20% — which is much better.
Put simply, strive to only charge what you can pay off each month. And if your utilization will be very high, consider paying down the balance before the statement closing date if you want to improve your scores.
How to Build Credit With Credit Cards: The Definitive Guide
When you connect your credit card to a budgeting tool like Mint, it can actually provide a clear glimpse into your spending habits.
Unlike with cash purchases, which, for most people, get lost in a vast abyss, credit cards allow you to see how much you’re spending — and in which categories — month after month, and year after year. In fact, you don’t even need to use a special tool; credit card issuers may provide a year-end statement with similar information.
Keeping tabs on your bill has other benefits, too. If you notice a suspicious charge, all you have to do is contact your credit card company — most cards come with a $0 fraud liability guarantee, which means you won’t be on the hook for fraud or theft.
Credit Card Security: 9 Do’s and Don’ts for Avoiding Identity Theft
Besides building credit, one of the main reasons to use a credit card is the ability to earn rewards: either points or miles toward free travel, or cash back toward statement credits.
Although many of the best rewards credit cards are targeted at users with high credit scores, you’ll find some rewards on beginner credit cards, too.
Take care to avoid spending extra money to earn rewards or snag a signup bonus. That would negate the value of any rewards you earn!
