If you've ever opened a credit card agreement and felt like you were reading a different language, you're not alone. These documents are packed with financial jargon that can make it difficult to understand what you're actually signing up for — and what it could cost you.
Knowing the key terms that appear on your statements, in your cardholder agreement, and on your credit report can help you make more informed decisions about how you use credit. It can also help you avoid unnecessary fees and interest charges.
This glossary breaks down the most common credit card terms in plain language, so you can feel more confident navigating the world of credit.
Annual percentage rate (APR)
The annual percentage rate (APR) is the yearly interest rate charged on any balance you carry on your credit card. While your card issuer calculates interest daily or monthly, the APR gives you a standardized way to compare the cost of borrowing across different cards.
In Canada, purchase APRs on standard credit cards typically range from 19.99% to 22.99%. But it's worth noting that your card may have different APRs for different types of transactions. Cash advances, for example, often carry a higher rate than regular purchases, and promotional balance transfer offers may come with a temporarily lower rate.
To understand how much interest you'd actually pay in a given month, divide the APR by 12. If your card carries a 19.99% APR, that works out to roughly 1.67% per month on any unpaid balance.
Grace period
A grace period is the interest-free window between the date your billing statement closes and the date your payment is due. During this time, you won't be charged interest on new purchases — as long as you pay your statement balance in full by the due date.
In Canada, federal regulations require a minimum grace period of 21 days on new purchases. This gives cardholders enough time to review their statement and arrange payment without incurring interest.
There's an important catch, though: if you carry a balance from one billing cycle to the next, you may lose your grace period entirely. That means interest could start accruing on new purchases immediately, from the date of the transaction. Paying your balance in full each month is a reliable way to take advantage of the grace period.
Minimum payment
The minimum payment is the smallest amount you need to pay by your due date to keep your account in good standing. Paying at least this amount helps you avoid late fees and negative marks on your credit report.
How it's calculated varies by issuer, but it's typically the greater of a fixed dollar amount (often around $10) or a small percentage of your outstanding balance — usually 1% to 3%, plus any interest and fees.
While making the minimum payment keeps your account current, it can be a costly habit over time. Because minimum payments barely chip away at the principal, a large balance can take years — or decades — to pay off, with a significant portion of each payment going toward interest rather than reducing what you owe.
Statement balance vs. current balance
These two numbers appear on your account, and they represent different things.
Your statement balance is the total amount you owed at the end of your most recent billing cycle. It's the snapshot of your balance on the date your statement was generated.
Your current balance is the real-time amount you owe, including any transactions, payments, interest, or fees that have been posted since your last statement closed. This number changes throughout the billing cycle as you make purchases and payments.
Paying the full statement balance by the due date avoids interest charges. You don't necessarily need to pay the current balance in full each month — but paying the statement balance ensures you're taking full advantage of your grace period.
Credit utilization
Credit utilization is the ratio of how much credit you're currently using compared to your total available credit. It's expressed as a percentage and is one of the key factors that influence your credit score.
To calculate it, divide your total credit card balances by your total credit limits, then multiply by 100. For example, if you have $1,500 in balances across all your cards and a combined credit limit of $10,000, your credit utilization is 15%.
Financial experts commonly suggest keeping your credit utilization below 30% to maintain a healthy credit score. Lower is generally better — but using no credit at all doesn't necessarily help either, since lenders want to see that you can manage credit responsibly. Credit utilization is reported to Canada's two major credit bureaus, Equifax and TransUnion, and can fluctuate from month to month based on your spending and payment patterns.
Hard inquiry vs. soft inquiry
When someone checks your credit report, it's recorded as either a hard inquiry or a soft inquiry. The distinction matters because one type can affect your credit score and the other cannot.
A hard inquiry (also called a hard pull) happens when you apply for credit — such as a credit card, mortgage, car loan, or line of credit. The lender requests your full credit report to evaluate your application. Hard inquiries appear on your credit report and can lower your score by a few points temporarily, typically for about 12 months.
A soft inquiry (also called a soft pull) happens when a credit check is done for reasons other than a new credit application. Common examples include checking your own credit score, a lender pre-approving you for an offer, or an employer running a background check. Soft inquiries do not appear on the version of your credit report that lenders see and have no impact on your score.
Secured vs. unsecured credit card
Credit cards fall into two broad categories based on whether they require a deposit.
A secured credit card requires you to provide a cash deposit upfront, which typically becomes your credit limit. If you deposit $500, for example, your credit limit would be $500. Because the deposit reduces risk for the issuer, secured cards are generally easier to qualify for. They're commonly used by people building credit for the first time or working to rebuild their credit after financial setbacks.
An unsecured credit card doesn't require a deposit. Instead, the issuer evaluates your creditworthiness — your credit score, income, and debt levels — to decide whether to approve you and what credit limit to offer. Most credit cards fall into this category. Approval depends on the applicant meeting the issuer's criteria, which can vary widely.
Balance transfer
A balance transfer involves moving an outstanding balance from one credit card to another — typically to take advantage of a lower interest rate. Many cards offer promotional balance transfer rates, sometimes as low as 0%, for a limited period (often 6 to 12 months).
This can be a useful strategy for paying down high-interest debt more quickly, since more of your payment goes toward the principal rather than interest during the promotional period.
However, a few things are worth keeping in mind. Balance transfers usually come with a fee, often around 1% to 3% of the amount transferred. Once the promotional period ends, the regular APR kicks in, which could be as high as — or higher than — the rate on your original card. And if you miss a payment during the promotional period, you may lose the promotional rate entirely. Reading the terms carefully before initiating a transfer is essential.
Cash advance
A cash advance is when you use your credit card to borrow cash — either by withdrawing money from an automated teller machine (ATM), using a convenience cheque from your card issuer, or transferring funds to your bank account.
Cash advances work differently from regular purchases in a few important ways. Interest typically begins accruing immediately — there's no grace period. The interest rate for cash advances is usually higher than the rate for purchases, often ranging from 22.99% to 27.99%. And most issuers charge a cash advance fee on top of the interest, usually a flat amount or a percentage of the advance, whichever is greater.
Because of these costs, cash advances can be an expensive way to access funds with a credit card.
Chargeback
A chargeback is a transaction reversal that you initiate through your card issuer when you dispute a charge on your account. It's a form of consumer protection that allows you to recover funds in situations where a transaction was unauthorized or went wrong.
Common reasons for filing a chargeback include fraudulent charges, being billed for goods or services you never received, receiving a defective product, or being charged the wrong amount. The process typically involves contacting your card issuer, providing documentation to support your claim, and waiting while the issuer investigates.
If the dispute is resolved in your favour, the charge is reversed and the funds are returned to your account. It's worth noting that chargebacks are intended as a last resort — most issuers expect you to attempt to resolve the issue with the merchant directly before filing a dispute.
Authorized user
An authorized user (sometimes referred to as an additional cardholder) is someone who has been added to another person's credit card account. The authorized user receives their own card and can make purchases, but the primary cardholder remains responsible for all charges on the account — including those made by the authorized user.
For the primary cardholder, adding an authorized user means taking on the risk that someone else's spending will appear on their bill. Any unpaid balances, late payments, or other issues on the account can affect the primary cardholder's credit.
For the authorized user, being added to an account can help build credit history, since the account's payment history may be reported to the credit bureaus under their name as well. This is sometimes used as a strategy for younger people or newcomers to Canada who are working to establish a credit history. However, if the primary cardholder misses payments or carries high balances, that negative activity could also appear on the authorized user's credit report.
