Imagine being trapped in debt for nearly four decades, all because of a credit card. That’s the harsh reality for many Australians today, as credit card debt accruing interest has soared to a four-year high, according to the Reserve Bank of Australia’s (RBA) September 2025 statistics, released on November 7, 2025. But here’s where it gets eye-opening: if someone with the average credit card debt of $5,330 makes only the minimum payment at the average interest rate of 18.61%, they’ll end up paying a staggering $15,891 in interest alone—and it’ll take them almost 40 years to become debt-free. That’s not even factoring in annual fees or additional purchases.
But here’s the silver lining: by simply adding an extra $150 to their monthly payment, they could slash their interest costs by $13,596 and clear their debt in just 4 years and 3 months—a jaw-dropping 34 years sooner. Let’s break it down:
| Payment Strategy | Total Interest Charges | Time to Repay |
|---------------------------|------------------------|---------------------|
| Minimum repayments | $15,891 | 39 years, 1 month |
| Higher repayments (+$150) | $2,295 | 4 years, 3 months |
| Savings | $13,596 | 34 years, 10 months |
These numbers are based on RBA data, assuming 30% of accounts carry debt accruing interest, and accounts for individuals with multiple credit cards, as per a 2025 Canstar survey. Interest calculations use the RBA’s average rate of 18.61%, with minimum repayments set at 2% or $20, whichever is higher.
And this is the part most people miss: Canstar spokesperson Laine Gordon warns, ‘It’s alarming to see credit card debt climbing back to levels we haven’t witnessed since July 2021. This is a clear sign that more households are relying on credit cards just to get by.’ Over the past year, interest-accruing credit card debt has risen in eight out of 12 months, indicating that many Australians are struggling to stay afloat as living costs surge.
While spending on credit cards dipped slightly in September, it followed a record high in August. Year-on-year, spending remains significantly elevated, suggesting that credit cards are becoming a lifeline for those trying to make ends meet. To add insult to injury, RBA data reveals that Australians with credit card debt are paying an average interest rate above 18%. At such rates, it’s no wonder so many feel trapped in a cycle of debt.
Here’s the controversial part: Some argue that financial institutions aren’t doing enough to educate consumers about the long-term consequences of minimum payments. Others counter that individuals must take personal responsibility for their spending habits. What do you think? Let’s debate this in the comments.
For those feeling overwhelmed by credit card debt, Gordon offers practical advice: ‘Switching to a low-interest card can provide temporary relief. Seven banks currently offer rates under 10% on Canstar.’ Avoiding the minimum payment trap is crucial—while it may feel manageable in the short term, it can cost thousands in interest and decades of financial strain.
Even small adjustments, like adding $150 to your monthly payment, can dramatically alter your financial future. ‘It’s not just about saving money,’ Gordon adds. ‘It’s about reclaiming control over your life.’ And remember, you’re not alone. The National Debt Helpline (https://ndh.org.au/) offers free financial counseling to help you create a plan and break free from debt for good.
