How Much Is Australia Paying In Credit Card Interest?

Aussies have a love affair with the ‘plastic fantastic’ – but it may be doing us more harm than good.

With just over $31 billion of Australian credit card debt currently on the books (ASIC), and just over $5 billion of credit card interest being charged on that $30 billion – it’s clear that the Australian passion for using a card is an expensive one. It’s resulted in an average Australian credit card debt of $4,154.86 per cardholder. On top of that, based on figures from the Reserve Bank of Australia, CANSTAR estimates that Australians collectively paid more than $35 billion in credit card interest in the past four years from August 2012 to August 2016.

While the size of that figure can in part be explained by our incredibly high credit card interest rates, credit card debt doesn’t just appear out of nowhere. Some of us just don’t know how to be smart with our credit cards, and that nationwide lack of financial smarts has racked up a $35 billion bill.

We could be doing a lot more than paying credit card interest


$35 billion is a staggering amount; it’s also one that, if it were redirected to the Federal Government, would almost wipe out the entire current deficit, which stands at $37.1 billion. This would subsequently eliminate the need for measures such as funding cuts to higher education and complex healthcare at aged-care providers, and (presumably) put an end to the government’s continued efforts to cut the family tax benefit.

Of course, we’re not saying that consumers should be giving that extra money to the government at all; we’re simply putting the amount of credit card interest that we all pay into perspective. Credit cards can be fantastic cash-flow tools, but only if you use them wisely.

Here’s an overview of some of the funding cuts outlined in the most recent federal budget that would be completely unnecessary if the government had an extra $35 billion handy.

Federal Budget savings initiative 2016 Estimated total savings/revenue over 4 yrs
Cuts to university funding $2 billion in savings
Tobacco tax $4.7 billion in revenue
Cuts to National Disability Insurance Scheme Savings Fund $2.2 billion in savings
Pause on Medicare rebate indexation $0.9 billion in savings
Cuts to welfare $1.29 billion in savings
Total $11.1 billion
Average credit card interest $35 billion

And those are just the larger measures! The 2016-17 Budget contained a huge number of “saving measures” designed to narrow the deficit, which wouldn’t be necessary if the government was able to make use of the money we are essentially throwing away on credit card interest payments.

The silver lining in the cloud of our nation’s credit card debt

It’s not all doom and gloom when it comes to the overall state of credit card debt in Australia. As CommSec points out, interest aside, credit card debt is actually at its lowest in 8.5 years!

We’re not sure this piece of good news would be particularly comforting to the average Australian with an outstanding credit card balance, but it’s good news nevertheless.

Note that the figure quoted by CommSec differs to the ASIC figure of $4,154.86 we quoted at the start of the article due to a few factors:

  • ASIC’s credit card debt clock, while based on RBA figures, provides a real-time estimate of current debt based on yearly trends, whereas CommSec is quoting a specific figure for one month of the year.
  • ASIC’s credit card debt clock presumably takes interest into account, whereas CommSec is talking solely about the average balance before interest owed.
