Ever wondered how credit card interest works? With US credit card balances now at a record high of over $1 trillion, it's a topic that's causing quite a headache for many. In short, credit card interest is a fee charged for borrowing money, and it accumulates when cardholders carry a balance from month to month.
By understanding the inner workings of credit card interest, you can unlock your card's full potential and minimize, or even completely avoid, those pesky charges.
Credit card interest works by applying an Annual Percentage Rate (APR) to the balance that isn't repaid at the end of each month. Basically, if you carry a balance into the next billing cycle, your credit card company will charge you interest.
When you sign up for a credit card, you'll see an interest rate. This is essentially the cost of borrowing money, charged if you're unable to pay off your balance before your next billing period starts. In credit card terms, this interest is usually expressed as a yearly rate, better known as the Annual Percentage Rate or APR.
Contrary to what you might think, the APR isn't charged annually. Instead, credit card interest compounds on a daily basis, meaning credit card companies use this rate to calculate your daily interest, and your bill is due each month.
However, this interest isn’t charged unless the balance carries over to the next month. If you're carrying a balance each month, understanding your APR is crucial to reduce the cost.
To estimate your interest charges, you'll need 3 bits of info:
Let's use an example. Say you have a travel rewards card with an average daily balance of $1,500 for a 30-day billing cycle, and your APR is 15.99%.
Here's what you do:
So, for this billing cycle, you'd get a charge of around $19.93 in interest. To get a completely accurate calculation, don’t round any of the numbers. You’ll probably need a spreadsheet to help you out!
Though it needs some back-of-the-napkin calculations, the principle is simple - carry a balance, and you'll pay interest.
Avoiding interest completely is ideal, but if that's not possible, minimizing it is the next best thing. Here are a few strategies you can use:
Unfortunately, no. Credit card issuers aren't required to give you a grace period. But there's a silver lining - many still do. And if they do offer a grace period, they're required to send you a bill at least 21 days before your due date.
Your credit card's APR is either fixed (generally unchanged, unless your payment is more than 60 days late or when a promotional offer ends) or variable, shifting with the prime rate, often starting with the prime rate before adding a margin.
Credit cards may feature several types of APR:
When it comes to handling credit card interest, a little knowledge and caution can go a long way. By making smart choices and steering clear of pitfalls, you can handle credit card usage without the burden of scary interest charges. Below is a useful table to guide you on what you should and shouldn't do:
Understand your APR
Pay bills on time
Use grace periods
Opt for low-interest cards if needed
Carry a balance
Make just the minimum payment
Ignore the fine print
Forget about cash advance APR
Despite the potential cost, credit card interest isn't all bad. In fact, if you understand the system and play by the rules, you can turn it to your advantage. However, it's important to weigh the pros and cons when it comes to credit card interest.

Yes, by paying off your statement balance in full each month, you can avoid paying credit card interest. Additionally, taking advantage of your credit card's grace period, typically 21 days from the purchase date to the payment due date, can help you avoid interest charges on new purchases.
Yes, your credit score is a big factor in determining your APR. Cardholders with excellent credit scores often receive lower rates, while those with lesser scores may be subject to higher interest rates. Understanding credit scores and improving yours can lead to better rate offers.
