Credit Card Glossary: Key Credit-Related Terms and Definitions You Need to Know

Understanding credit card terminology is an important part of managing your finances and building good credit, as it helps you avoid costly mistakes and achieve your financial goals. Check out our list of credit card terms to compare offers, understand your statements, make informed decisions, and improve your overall financial literacy.

1. Annual fee

An annual fee is a yearly charge for using certain credit cards and accessing specific credit card benefits or services. Typically, credit cards with annual fees are rewards credit cards that offer cash back, points, or miles. Premium credit cards with annual fees might offer a higher rewards rate for a variety of eligible purchases, travel perks like room upgrades, lounge access and insurances.

2. Annual percentage rate (APR)

Annual percentage rate (APR) refers to the yearly interest rate you’ll pay if you carry a balance on your credit card, including any fees. In other words, if you don’t pay your bill in full when it’s due, the amount you owe is subject to interest. The card’s APR will depend on your credit history and the card. What’s more, rates can differ between transactions, such as balance transfers, purchases and cash advances.

3. Authorized user

You can authorize another person to use your credit card. They typically get their own card tied to your account, but they are not legally responsible for paying the bill. The primary cardholder is solely liable for all charges made to the account, including those by the authorized user.

4. Available credit

Your available credit is the amount of money you can still spend on your credit card – it’s your credit limit minus your current balance. Your available credit decreases as you make purchases with your card. Depending on your credit card issuer, going over your available credit could lead to extra fees, declined purchases or even a closed account.

5. Balance

A credit card balance is the total amount you owe the issuer, including purchases, cash advances, fees, and interest.

6. Balance transfer

A balance transfer is when you move your existing debt to a new credit card. Transferring balances from the card or loan with a higher annual percentage rate (APR) to a card with a lower APR can save you money on the interest you’ll pay.

7. Balance transfer APR

The interest rate applied to balances transferred from one account to another.

8. Billing cycle

Also called a billing period or statement period, a credit card’s billing cycle is the approximately one-month period between statements’ closing dates. The transactions during the billing cycle are added to your previous balance (if any) and determine your statement balance at the end of each cycle. Your minimum payment will be based on this amount and is often due 21 to 25 days later.

9. Cash advance

Most credit cards let you withdraw cash or perform a transaction that’s essentially cash equivalent, such as sending money to a bank account, purchasing a money order, etc. against your credit limit. Generally, you can only cash out to your card’s cash advance limit, which may be lower than your regular credit limit. However, the costs (fee and high interest rates) make it an expensive way to get cash.

10. Cash back

Cash back is a form of credit card reward you earn by making purchases with your credit card. Cash back credit cards give you a percentage of the amount you spend. Depending on the card, this could be a flat rate on all purchases, higher rates in specific categories (e.g., grocery stores, gas stations) or rotating bonus categories that change periodically (e.g., quarterly). You can redeem those rewards for statement credits, account deposits, purchases or other types of redemptions.

12. Credit bureau

Credit bureaus, also known as credit reporting companies or consumer reporting agencies, are companies that receive and compile information about your borrowing and repayment history, as well as other types of information from creditors, bankruptcy court records, and other sources. This also includes personal information like your full name, address, and Social Security number.

13. Credit limit

A credit limit is the maximum amount of money a lender allows you to borrow on a credit card or line of credit, acting as your total spending cap for that account, determined by factors like your income, credit score, and debt.

14. Credit score

A credit score is a three-digit number (usually ranging from 300 to 850) that acts as a quick summary of your creditworthiness, predicting how likely you are to repay what you’ve borrowed. It’s calculated from information in your credit report, focusing on factors like payment history, amounts owed, and length of credit history, with major models being FICO and VantageScore. Lenders use it to see how risky it is to lend you money and at what interest rate.

15. Dispute

A credit card dispute is a formal challenge to a credit card charge due to fraud, a billing error or an issue you could not resolve directly. If you notice an unauthorized transaction on your statement, contact your credit card issuer and dispute it. They will investigate your claim and decide whether to reverse that charge.

16. Due date

A credit card’s due date is when your payment must arrive to keep your account in good standing. You’ll need to make at least the minimum payment on your account if you want to avoid a late fee. Your credit card payment is usually due 21 to 25 days after your statement date, so the due date falls on the same day each month.

17. Fixed APR

A rate that doesn’t increase or decrease based on changes to an underlying index rate. The rate can still change, however, if you violate the terms of your credit card agreement.

18. Fraud

If an unauthorized person uses your card or card information to make unauthorized purchases or withdrawals, that’s fraud. A few examples of credit card fraud include cash withdrawals, opening new accounts, often through stolen card details from data breaches, skimming devices, phishing, or physical theft.

19. Grace period

A credit card grace period is the interest-free time between the end of your billing cycle and the payment due date. Generally, if you pay your card balance in full before the due date, you won’t pay any interest.

20. Interest rate

The APR (annual percentage rate) on a credit card represents the yearly cost of borrowing money when you carry a balance. It includes the interest rate and, in some cases, additional fees. Typically, you’ll have several interest rates: one for purchases, one for cash advances and one for balance transfers.

21. Introductory rate

An introductory APR is a type of promotional rate offered on a new credit card for a set number of months. Intro rates can be as low as 0% on purchases or balance transfers or both. However, when this promotional period ends, your 0% APR will reset to the regular ongoing APR. So, if you’re still carrying a balance on your card, you’ll start accruing interest on that remaining amount.

22. Late payment fee

A late payment fee is the dollar amount that may be charged to your account if the card issuer doesn’t receive the minimum credit card payment by the due date.

23. Minimum payment

A credit card minimum payment is the smallest amount you can pay each billing cycle and remain in good standing with your credit card issuer. Paying the minimum on a credit card on time can help you avoid penalties and credit card fees. But you’ll still be charged with interest when you carry a balance.

24. Payment history

Payment history is your financial track record showing how you’ve paid your accounts over the length of your credit. Consistently paying bills on time builds a strong payment history, making it easier to borrow money and get better rates, while late or missed payments harm your creditworthiness.

25. Penalty APR

A penalty APR is an elevated interest rate applied to your credit card balance if you violate your credit card terms by doing things like missing a payment, paying late, or exceeding your credit limit.

26. Personal identification number (PIN)

A personal identification number (PIN) is a numerical code used to authenticate financial transactions. A PIN is personal to the cardholder, and for the safety and security of yourself and your finances, it should be kept secret and not given out to anyone.

27. Prepaid card

Prepaid cards provide a relatively simple way to pay for purchases without taking out a line of credit or using a bank account. Prepaid cards can be either reloadable or non-reloadable, with reloadable ones letting you add funds after the initial purchase. A reloadable prepaid card can be a practical alternative to cash, providing a quick and secure way to pay online, in-store or using your digital wallet.

28. Principal

The principal balance on a loan or credit card is generally how much you borrow without any interest or fees, and it’s the core sum that needs to be repaid over time. And interest can accrue on the principal based on the account’s interest rate.

29. Purchase APR

It’s the interest rate that you pay when you charge standard purchases when you’re shopping in store or online to your credit card and don’t pay off your balance by the due date.

30. Rewards card

Rewards credit cards let you earn points, miles or cash back from every dollar you spend. The value of your accumulated rewards can vary depending on the type of credit card you have.

31. Secured credit card

A secured credit card is a type of card that requires a security deposit, which typically becomes your credit limit. This makes secured cards easier to get if you have poor or no credit and can help you build or improve credit with responsible use.

33. Statement

A credit card statement is a summary of your credit card activity throughout a billing cycle. Statements include important deadlines, past transactions, interest charges and fees, and other information. Your bank or credit card provider issues statements at the end of each billing cycle, usually once a month.

34. Unauthorized transaction

An unauthorized transaction is any payment, withdrawal, or transfer from your bank or credit card account that you didn’t approve, often due to stolen card details, identity theft, or account takeover. If someone else made a transaction without your permission, even if they’re someone you know, immediately contact your bank or card issuer’s fraud department, report the charges as fraudulent, and follow their instructions, which usually involve disputing the transaction, changing passwords/PINs, and potentially getting reimbursement.

35. Unsecured credit card

An unsecured credit card is a standard credit card that doesn’t require a cash deposit or collateral. Instead, the lender approves you based on your creditworthiness and extends a line of credit, making it the most common type of card.

36. Variable APR/variable rate

A variable rate is linked to a benchmark rate, often the federal prime rate, which moves with the Federal Reserve’s rates. That’s the rate that banks charge to their most creditworthy customers. Credit cards typically have a variable APR.

37. Zero liability policy

Zero liability protection is a guarantee by the credit card issuer that you won’t be held responsible for any fraudulent or unauthorized transactions made with your credit or debit card.
