What is the difference between a debit card and a credit card? A credit card is borrowed money you pack back, while a debit card is linked to your bank account. Here's how to decide which one to use.
Credit cards use borrowed funds, attracting average interest of 20.99% p.a. if not paid in full.
Debit cards access your own money, often with $0 account fees and lower surcharges.
Use a credit card for travel deposits or to build credit; a debit card offers strong cost control.
Cards are the most popular way to pay in Australia, with data from the Reserve Bank of Australia showing they make up around 75% of all payments. Almost all adult Australians have more than one debit card and many have a credit card, with Finder analysis showing there are around 40.9 million debit cards in Australia and over 13.4 million credit cards in circulation.
So, what's the difference between a credit card and a debit card? And is one better than the other? We've put the details of each card side-by-side to help you decide when it's better to use a credit card or debit card for your spending.

Credit cards
How they work
You can use a credit card to spend up to a set amount (your approved credit limit). You're required to pay back what you charge to the card, but not all at once – you can pay it off over time, you just need to pay at least the minimum amount listed on your statement. Most credit cards can be added to digital wallets.
Costs
If you don't pay off your credit card in full by the statement due date, you'll be charged interest.
The average standard interest rate is currently at 20.99% p.a. according to the RBA.
Many cards also charge an annual fee.
On top of these account costs, credit card surcharges can range from 1% to 2% of the transaction value, compared to around 0.2% to 1% for debit cards.
If you're travelling overseas or shopping online with overseas brands, expect to pay an international transaction fee of around 2% to 4% (unless you get a credit card that offers no foreign transaction fees).
Perks
Credit cards are a popular way to free up cashflow and earn reward or frequent flyer points on your everyday spending.
When you apply for a credit card, this is listed on your credit report whether or not you're approved. If you use your card responsibly and make timely repayments, having a credit card can help improve your credit score.
Security
Most credit cards offer 24/7 fraud monitoring services to help protect you against suspicious activity. If someone uses your card for fraud, the transaction amount will often be refunded under a zero liability policy. If your card is used to make a fraudulent transaction, it won't impact your bank balance or savings.
Debit cards
How they work
Debit cards are linked to your everyday bank account so you can spend your own money. This means there are no repayments, although you do need to have the amount of money needed in your bank account when you pay with a debit card.
If you have a Visa or Mastercard debit card, you can often add it to mobile wallets. There are also some virtual debit cards, although this is more common with business accounts or gift cards.
Costs
Debit cards don't usually attract interest charges because you're using your own money.
Most everyday bank accounts that offer debit cards also offer $0 account fee options, meaning you can often use a debit card without paying any extra costs.
It also costs merchants less money to process debit card payments, which is why there is often a lower surcharge (or no surcharge) compared to credit card transactions.
Similar to credit cards, an international or currency conversion fee may apply when you're travelling overseas or shopping online with companies based overseas, unless you get a debit card with no foreign transaction fees.
Note: For tap-and-go transactions, you may find the surcharge is higher than if you insert your debit card and enter the PIN. This is because Visa and Mastercard process the contactless payments, which is more expensive. The EFTPOS system charges lower fees, and they process payments where you swipe or insert your debit card and choose "cheque" or "savings".
Perks
In comparison to credit cards, there are very few debit cards that offer you reward points or other complimentary extras.
Credit history
Unlike credit cards, your debit card account details aren't listed on your credit report and don't impact your credit score.
Security
Like credit cards, debit cards offer a zero liability policy, which means you will be refunded for fraudulent transactions. Some debit cards also offer fraud-monitoring services. If you're subject to fraud, you will be left without your money until the bank has fully investigated the claim. This could take a few weeks or several months.
Our expert says
"Debit cards are great for cost control and controlling everyday spending. When travelling, I'd always take a credit card as well. The reason? Some hotels won't take a debit card for your security deposit; others will but withdraw the deposit immediately and then take a fortnight or more to refund it. The same goes for cruises, with many cruise lines simply not accepting debit cards on board. So a credit card backup can still be useful even if your main travel budget is already available from your debit card "
With a credit card, you get access to money you might not having in savings, with the flexibility of paying off the balance over time. You also have more options to collect rewards and other perks.
But a debit card usually means you will pay fewer fees, and less chance of ending up in debt, because the money is coming straight from your bank account.
Choosing between a credit card vs a debit card really comes down to your goals and habits. One thing to keep in mind is that a credit card, when used responsibly, will help you build your credit rating. So, it might be the better choice for you if you are planning to buy a home in the next few years, as it will help you build your credit up.

Important information about this website
Finder is a comparison service. We do not compare every product or every provider in the market.
We make money through commercial arrangements with some of the providers on this site. Products marked 'Sponsored', 'Promoted', 'Featured' or 'Advertisement' appear as a result of a commercial arrangement.
Our editorial content, product reviews and any 'Top Pick' designations are prepared independently of these commercial arrangements.
The default order of products in our tables can be influenced by commercial arrangements. You can re-sort or filter using the controls above each table.
Some content on this site may be generated or supported by AI tools. You should verify details directly with the provider.
Finder is one of Australia's leading comparison websites. We are committed to our readers and stand by our editorial principles.
Our comparison service does not include every product or every provider in the market. Some product issuers offer their products under multiple brands or through associated companies. Where we can, we identify the underlying issuer so you can compare like with like, but you should always check with the provider directly to confirm which brand you are dealing with.
Finder is a comparison website and an intermediary. We are not a product issuer and we do not provide personal financial or credit advice. When you click a link to a product, or apply for a product through our site, you deal directly with the product issuer. We may receive a referral fee, commission or other payment from the issuer if you click through, apply or take out a product. We describe these arrangements in more detail under 'How we make money' below.
Product features, fees, terms and eligibility criteria are set by the product issuer and may change. We rely on information supplied by issuers when we present product details on our site. Before you apply for or take out any product, you should confirm the details directly with the issuer.
We earn revenue from Finder in four principal ways:
Referral fees and commissions. When you click a product link, complete an enquiry form or apply for a product through our site, we may receive a referral fee, commission or other payment from the product issuer. We may also receive payment based on the volume of leads or conversions we send to an issuer.
Sponsored placements. Products marked 'Sponsored', 'Promoted', 'Featured' or 'Advertisement' appear as a result of a commercial arrangement between Finder and the issuer. These labels always indicate a paid placement. We do not use them for editorial choices.
Display advertising. Banner advertising, newsletter advertising and similar display ads on our site are paid by advertisers.
Content sponsorship. Some articles, videos and social media posts are sponsored by an issuer and are clearly labelled as such.
Our editorial opinions, product reviews and any 'Top Pick' designations are prepared independently of these commercial arrangements. A 'Top Pick' is an editorial choice made by our writers and editors based on the criteria described on each comparison page. A 'Top Pick' is not a personal recommendation and does not mean the product is appropriate for your circumstances.
If you would like to know whether we have a commercial arrangement with a specific product issuer, please contact us.
When products are grouped in a table or list, the default order can be influenced by commercial arrangements we have with product issuers. In some categories, sponsored or featured products appear in the top positions of the table by default, and are always labelled as such.
Other factors that influence default order include price, fees and features, and (where relevant) our editorial view of the product.
You can re-sort every comparison table using the controls above the table. You can filter by product features that matter to you. The order you see after re-sorting or filtering is not influenced by commercial arrangements.
