Is It Better To Pay Off Debt Or Invest? The Surprising
Renan Filho · Founder & Tech Builder
Quick answer: Pay off debt or invest? In 2026, with the RBA holding rates at 3.35% and the ASX 200 hitting record highs, the answer isn't obvious. Your super might earn 7%, but your credit card costs 20%. Here's the surprising truth: it depends entirely on which debt. A$10,000 invested at 7% becomes A$76,000 in 30 years. But that same A$10,000 on a 20% card becomes A$2.37 million in interest if unpaid. The math is brutal.

The 2026 Australian Reality Check
The RBA has held the cash rate at 3.35% for six months. Iron ore exports are down 4% this quarter, but the ASX 200 is up 11% year-to-date. This creates a weird paradox. Your mortgage is around 6% variable. Your HECS debt is indexed at 4.5%. Your credit card is at 19.9%. And your super fund just returned 9.2% after fees in 2025. The smart move in Australia is not one-size-fits-all. It's a tiered system. Pay off the 20% card first. Always. Then look at your mortgage. Then invest. The order matters more than the amount.
The Superannuation Advantage You're Ignoring
Your employer puts in 11.5% of your salary. That's A$11,500 on an A$100k salary. If you add just A$50 a week extra into super, the tax savings are immediate. At the 37% tax rate, that A$2,600 annual contribution costs you only A$1,638 after the tax deduction. The super fund pays 15% on earnings. Over 30 years, that small A$50 weekly sacrifice grows into an extra A$38,000. Compare that to paying off a 6% mortgage faster. The mortgage saves you 6% guaranteed. Super gives you a 22% tax break today plus 7% growth. Super wins for long-term wealth. But only if you don't need the cash before 60. This is the trade-off nobody talks about.
The Credit Card Trap vs. The Investment Opportunity
Here's the shocking comparison. A$5,000 on a Westpac Altitude card at 20.99% interest. If you pay A$100 a month, it takes 7 years to clear. You pay A$3,400 in interest. Now, A$5,000 in a Vanguard Australian Shares ETF. Over 7 years, at 7% average, it grows to A$8,028. The difference is A$5,428. That's a real loss. Now, the NAB Rewards card with 55 days interest-free. If you pay the full balance monthly, you pay zero interest. Then your A$5,000 works for you. The card is a tool. The debt is the problem. Use the interest-free period to your advantage. Set up auto-pay. Never carry a balance. The ASIC has strict rules on responsible lending, but they can't force you to be smart.
The 5 Best Financial Products in Australia for 2026
I've ranked the top five products based on cost-benefit for the average Australian. This is not a sponsored list. This is practical advice. You need a card that rewards spending without punishing you. You need an investment platform that's cheap. And you need a strategy that pays down debt while growing wealth. Here's the ranking.
The Verdict: When to Pay Debt, When to Invest
Here is the definitive answer for 2026. Pay off any debt above 10% interest first. That's credit cards, personal loans, and buy-now-pay-later schemes. These are wealth killers. Then, invest in your super up to the concessional cap of A$30,000. The tax break is a guaranteed 22-32% return. Then, pay extra on your mortgage. The 6% interest is tax-free savings. Finally, after your mortgage is below 60% loan-to-value, invest in ETFs outside super. This order is not exciting. But it's mathematically optimal.
Practical example in Australia
A$10,000 in a super fund with 7% returns over 30 years grows to ~A$76,000
