Nearly half of Australian adults — 47% — cannot say whether the interest rate on their savings account is keeping up with inflation. The average person holds $42,246 in savings, but that number jumps to $62,775 for homeowners without a mortgage and drops to $24,890 for renters. What that gap really shows is a decision that every Australian with both savings and debt has to make: which dollar works harder for you.

Those figures come from research by Savings.com.au and Money.com.au, and they paint a clear picture. Australians in their 30s to 50s tend to hold lower savings balances because mortgage repayments eat up a large slice of disposable income. The question is whether that’s the right call — or whether some of that cash should be sitting in a savings account instead. The answer changes depending on your interest rate, your tax bracket, and whether you have an offset or redraw facility. Inflation-proof savings strategies only work if you know what you’re actually earning.
Here’s what you actually need to know.
What the Savings vs. Debt Payoff Decision Really Comes Down To
At the heart of this decision is a concept called your net effective return — the return you actually keep after inflation, tax, and the interest you’re paying on debt.
What I tend to notice is that most people compare the headline savings rate to the headline mortgage rate and call it a day. But the net effective return is what actually moves your wealth forward. Savings versus investing follows the same logic — the net number is what counts.
What the Data Actually Shows About Australian Savings and Debt
The research gives us a clear ranking of who holds what, and why it matters for the savings-versus-debt calculation.

| Housing Status | Average Savings | Key Financial Strategy |
|---|---|---|
| Homeowners without mortgage | $62,775 | Investing or high-interest savings |
| Homeowners with mortgage | $38,692 | Offset or redraw account |
| Renters | $24,890 | Build emergency fund first |
The average savings figure of $42,246 masks a big split. Homeowners without a mortgage have more than two and a half times the savings of renters. That’s partly because they’ve had longer to build wealth, but it’s also because their housing costs are lower — no mortgage payment means more cash to stash away.
For homeowners with a mortgage, the dilemma is most acute. Every dollar you hold in a savings account earning 4% is a dollar you could have used to reduce a mortgage costing 6% or more. The difference is 2 percentage points in your pocket — or rather, out of it.
That 47% figure is the biggest red flag in the data. If you don’t know what your savings account is earning after inflation, you can’t make an informed choice. A savings account that pays 4% when inflation is running at 3% gives you a real return of roughly 1% before tax. A mortgage costing 6% is eating value at 6%. The gap is 5 percentage points.
If you’re in the 12% whose savings genuinely beat inflation, the case for saving over paying down debt is stronger. But you’d need to be earning a rate that clears both inflation and tax — and with most high-interest savings accounts hovering in the 4–5% range, that’s a narrow window. Automated savings strategies can help you build a habit, but they won’t fix the rate gap if your debt is higher than your savings return.

Three Mistakes That Cost Australians the Most
Not knowing your savings rate versus inflation
This is the most common gap, and it’s the one that feeds all the others. Research from Money.com.au found that 26% of Australians who do track their savings rate say it’s below inflation, 16% say it roughly matches, and only 12% say it outperforms. That means the vast majority of people who check are earning a negative real return. If you’re not checking at all — and 47% aren’t — you could be losing purchasing power without realising it. The fix is simple: look up your savings account’s interest rate, find the current inflation rate, and subtract. If the result is negative, your cash is losing value.
Treating all savings as equal
A dollar in a savings account is not the same as a dollar in an offset account. The RBA’s Financial Stability Report notes that households with mortgages have continued to make extra payments into offset and redraw accounts, building savings buffers while reducing their interest bill. The difference is that interest saved on a mortgage is tax-free, while interest earned in a savings account is taxable at your marginal rate. For someone in the 32.5% tax bracket, a savings account earning 4% delivers roughly 2.7% after tax. An offset account saving 6% on a mortgage delivers the full 6% — tax-free. That’s more than double the effective return.
Holding too much cash while carrying high-interest debt
The average Australian holds $42,246 in savings. But if you’re carrying credit card debt at 18% or a personal loan at 10%, that cash is costing you every day. The emergency fund rule of thumb — 3 to 6 months of expenses — still applies. Beyond that, the math is clear: paying down debt that costs more than your savings earn is a guaranteed return. Expense tracking apps can help you find the extra cash to make the move.
The Practical Way to Decide Where Your Next Dollar Goes
Start with your emergency fund
Before you put any extra money toward debt, make sure you have a cash buffer. The RBA data shows that just over 1% of variable-rate owner-occupier borrowers were experiencing a cash flow shortfall at the end of 2025. That’s a very low number, but it means the other 99% had enough to cover their repayments. Three months of essential expenses is the minimum. Keep that in a savings account or offset account where you can access it instantly.
Use offset and redraw before extra repayments
If you have a mortgage with an offset account or redraw facility, that’s almost always the best place for your spare cash. It reduces the interest you pay while keeping the money accessible. The RBA confirms that households have been adding to these buffers, and for good reason. The effective return equals your mortgage rate — tax-free. No other savings product can match that for a homeowner with a mortgage.
Compare your net effective return on savings vs debt
For renters or homeowners without a mortgage, the calculation is simpler. Take your savings account interest rate, subtract tax at your marginal rate, and subtract inflation. That’s your real return. If it’s positive, saving has merit. If it’s negative, paying down any debt that costs more than your savings earn is the better move. For someone with a mortgage at 6% and a savings account at 4%, the gap is 2 percentage points — or more after tax.
What to watch for in the coming months
Interest rate changes shift the balance. The RBA’s cash rate movements affect both mortgage rates and savings rates. If savings rates rise faster than mortgage rates, the case for saving strengthens. If mortgage rates outpace savings rates, debt payoff becomes more attractive. The ABS data shows new housing loans reached a record $62.9 billion in December 2025, suggesting the property market is still absorbing a lot of credit. Keep an eye on both rates and adjust your strategy as they move. Advanced savings techniques can help you optimise once you’ve decided on the right split.
If you’re running a small business or have complex tax affairs, the decision gets more nuanced. Business and tax advice online can help you factor in things like company structure, tax deductions, and cash flow timing.

Your Net Effective Return Is the Only Number That Matters
The research Money.com.au and Savings.com.au have published makes one thing clear: most Australians don’t know the real return on their savings. Without that number, you can’t compare savings against debt payoff. The 12% of people whose savings beat inflation have a genuine choice. The other 88% need to do the math — or let the math make the decision for them. An offset account paying your mortgage rate tax-free is hard to beat. A savings account returning less than inflation after tax is hard to justify.
