What would you like to learn about first?
How does a credit card work?
A credit card works as an unsecured revolving line of credit. You make purchases using the card and at the end of your billing cycle, you receive a statement that tells you the total amount you owe for that period.
Based on your perceived ability to make repayments, credit card companies assign you a credit limit, which is the maximum amount of money you can borrow at one time. Unlike a debit card that uses your own money to make purchases, you are borrowing the bank’s money when you use a credit card – and if you don’t pay that money back on time, you’re charged interest.
How credit card interest works
As you make purchases on your credit card, your debts will begin to collect interest if you don’t pay the whole balance back by the end of the statement or interest-free period, also known as the grace period. Depending on the card, your purchases will collect an interest rate usually between 9.99% and 21%, however it can be as high as 36% and as low as 1.99%.
- If you’ve used your card for an ATM withdrawal or any other transaction that’s considered a cash advance, you’ll accrue interest at the cash advance rate of around 24%. This interest is usually charged immediately, as there is no grace period offered when taking out a cash advance.
- If you decide to balance transfer your debt down the track, which means you move your debt onto a single credit card that offers a lower introductory interest rate for a specified period of time, you’ll also accrue a revert rate once the promo period is up – which is usually the same as the cash advance rate or standard interest rate. Some cards do offer 0% promotional periods on balance transfers, so this is something to keep in mind during your comparison.
Each month, you’ll receive a statement that will detail the transactions you’ve made, the total outstanding balance you have and any interest you’re accruing. While you’re only required to pay a minimum repayment each month (usually 2-10% of your total balance), it’s best to pay as much as you can. If you pay your entire balance in full, you can take advantage of at least 21 interest-free days in the next statement period. If you don’t pay your entire balance in full, the remainder will start to collect interest. If you miss the minimum repayment, you could be charged late payment fees.
What are the features of a credit card?
- Credit limit. This is the maximum amount of money you can borrow using your credit card, this can be as low as $500 for a student credit card and as high as $20,000 for a high income earner.
- Interest-free days. Interest is the cost to borrow money using a credit card. Interest is charged as a percentage per annum (known as the APR) and varies depending on whether you’re using your credit card for a purchase or a cash advance. Pay your balance in full by the statement due date and you get up to a number of interest-free days on purchases in the next statement period. 21 days is the minimum interest-free period offered on all cards in Canada.
- Balance transfers. If you’re struggling to pay off an existing debt because of interest costs, you can transfer the debt to a credit card with a different provider and get a promotional interest rate on the balance transfer for an introductory period. Many card issuers offer 0% on balance transfers and the promotional periods can last up to 6 months or more. This will give you time to pay down your debt while paying a low or no interest rate on the balance. Keep in mind you will be charged a revert rate for making new purchases on this card, with revert rates usually sitting around 19.99% or higher.
- Cash advances. Using your credit card to get cash from an ATM is considered a cash advance transaction. Cash advances attract a cash advance fee and a higher interest rate that is usually charged from the moment you withdraw your cash.
- Rewards programs. You can reward your spending by opting for a card that earns rewards or travel points when you make eligible purchases. Many of these cards also offer thousands of bonus points when you meet a spend requirement after signing up. However, these cards often come with higher annual fees, since you’re being offered many more perks.
- Contactless payments. For purchases under $100, tap your credit card or mobile-pay compatible device against a contactless reader to complete a purchase in seconds. This means you can bypass signing or inputting your PIN into the credit card terminal.
- Insurance coverage. Most platinum, gold and black cards offer some form of complimentary insurance. This can include everything from purchase protection insurance and extended warranty coverage to overseas medical travel insurance, car insurance and accident insurance. Most regular credit cards offer purchase protection insurance and extended warranty coverage only.
- Extra features. Some credit cards come with extras such as airport lounge access, concierge services, invitations to exclusive events, discounts with partnered retailers and much more.

What are the costs of a credit card?
- Repayments. Although you’re required to make the minimum repayment when your statement is issued, you’re free to repay as much as you like and as often as you like beyond this minimum. The minimum repayment is usually only 2% to 10% of your outstanding balance, so it’s best to pay your account in full (or as much as you can) each statement period to reduce your interest costs. You will pay a late payment fee if you don’t make the minimum repayment by the statement due date.
- Annual fee. This is the cost to own a credit card. The annual fee ranges from $0 to hundreds of dollars depending on the type of credit card. The credit card annual fee is deducted from your available credit and accrues interest at the purchase rate if it isn’t paid in the first statement period.
- Interest rates. Interest is the price you pay to borrow money. Credit card interest rates are much higher than other types of financing options because credit cards are an unsecured product; financial institutions have no rights to take your assets if you default on your repayments.
- Other fees. Other fees you may run into include late payment fees, overlimit fees (a fee for spending past your credit limit), rewards program membership fees and cash advance fees.
What types of credit cards are suitable for beginners?
In Canada, Visa, Mastercard and American Express issue credit cards with banks, financial institutions and even some retailers. There are many types of credit cards on the market to suit different cardholders’ needs. It can be wise to begin with a no-frills credit card so you can understand how credit cards work before upgrading to a fancier and possibly more expensive product.
These types of credit cards are suitable if you’re just starting out:
- Low interest credit cards. Low interest rate credit cards typically feature a low purchase rate of interest. This is beneficial if you don’t pay back your balance in full by the statement due date. These credit cards can also offer a low interest rate on purchases for a promotional period. Low interest credit cards are suited to beginners still finding their feet making repayments. Paying off a debt over a couple of months is far cheaper with a low rate credit card than a rewards or premium credit card.
- No annual fee credit cards. This type of credit card costs nothing to own up front. However, the rates of interest can be higher than low rate credit cards. A no annual fee credit card can sit unused in your wallet and it won’t cost you a thing. These types of credit cards are suited to beginners who are looking to build their credit history, but don’t want to go all-out on a credit card with lots of features.
- Low income credit cards. Low minimum income credit cards have a low credit limit. Typically your annual income must be about $12,000 or greater to service the minimum credit limit of $500. Low income credit cards are typically either low rate or low fee credit cards. Low minimum income credit cards are suited to beginners who either have a low income or want a low credit limit to avoid the temptation to overspend.
- Student credit cards. Students looking to avoid paying a high annual fee and high rates of interest generally look for student credit cards when comparing products. These cards tend to offer perks that attract students, including retail and movie ticket discounts.

How to apply for your first credit card
Applying for a credit card is as simple as comparing your options, figuring out which card you want, making sure you meet the eligibility requirements, gathering the necessary documents and submitting an online application form. You will be asked about your income, assets and liabilities and will need to prove your identity. Most banks and providers will give you a response within 60 seconds and if you’ve been approved, you will receive your card in the mail about 10 days later. The entire application process takes less than 10 minutes, provided you have the necessary documents on hand.
The requirements will vary between cards, but you can browse some of the criteria below:
Eligibility requirements
- Minimum income. This is how much you need to earn every year to be eligible to apply. Low income credit cards usually require cardholders to earn at least $12,000 annually.
- Age. You must be over the age of 18, or the age of majority in your province or territory.
- Residential status. You will need to be a citizen or permanent resident of Canada. Some financial institutions offer credit cards to applicants with a student or temporary resident visa.
- Good credit history. You will likely need to have a good credit history to be eligible to apply. If you do not have any credit history to date, you may only be eligible for a low credit limit. As you build credit history by using your credit card, you can apply for a limit increase in the future.
Necessary documents
- Income information. You’ll need to provide copies of your most recent paycheques to prove your income. If you’re self-employed, you can provide your tax return instead.
- Identification. You will need to verify your identification with the credit card company before your application can be finalized. You can do this by providing your driver’s licence, passport or other form of valid Government-issued ID.
Dos and don’ts of your first – or any – credit card
Here are some good credit card habits to get into and some mistakes to avoid:
Do
- Make regular repayments. Credit cards are not free money. You need to make at least the minimum repayment every month so you can avoid late payment fees, stop your account from going into default and maintain a good credit history. However, you should always aim to pay more than the minimum to avoid being sucked into the cycle of debt.
- Stay within your budget. Having a credit card means you can temporarily spend more money than you actually have. This can make it tempting to buy things you normally wouldn’t. The best practice is to treat your credit card as if you were spending your own money, and if you need to spend more, pay it off as soon as possible.
- Educate yourself. It’s important to understand how credit cards work. For example, remember that ATM withdrawals count as cash advances and will immediately charge a higher interest rate. Even if you have an introductory 0% interest rate on your balance transfer card, you’ll still need to make repayments each month and you can only take advantage of interest-free days when you pay your balance in full. Understand the fees and charges that come with most credit cards before you apply.
Don’t
- Make cash advances. When you use your credit card to get money from an ATM, you’ll be charged a cash advance fee of a couple of dollars as well as the cash advance interest rate, which can be higher than your standard interest rate and is charged immediately as soon as you withdraw the cash. Interest-free days do not apply when you use your credit card for a cash advance.
- Share your credit card information. Apart from directly logging into your online banking or your bank’s official app, do not enter your credit card information or log-in details into any email, text message or third-party website, with the obvious exception of making purchases from a trusted source.
- Apply for a credit card you can’t really afford. Many people who apply for their first credit card choose a no annual fee or low rate credit card. Rewards credit cards can be a great way to get something for nothing, however, these products generally charge higher annual fees and interest rates and tend to be better suited for those who have experience with a credit card.
