If you’re tracking your investment performance in 2025, focusing only on headline returns could leave you with a misleading picture. The real rate of return—your investment’s growth after accounting for inflation and taxes—is the true yardstick for building wealth in today’s economic climate. Let’s unpack why this figure is so important, how it’s calculated, and what every Australian investor should watch out for this year.
The real rate of return measures the actual increase in your purchasing power after removing the effects of inflation and, often, taxes. If your term deposit yields 5% but inflation runs at 4%, your real return is only about 1%. In a year marked by persistent cost-of-living pressures and shifting tax rules, ignoring the real rate means you might be treading water—or losing ground—even when your account balance is growing.
Formula:
This year, Australian investors face a unique set of headwinds and opportunities:
For example, if you earned 6% from a balanced super fund in FY2024-25, but inflation was 3.2% and you pay 15% tax on earnings, your real after-tax return shrinks to just over 2%.
It’s not enough to chase high headline returns. Here’s how savvy Australians are optimising their real gains this year:
Consider this scenario: Two investors both earn a 7% nominal return. One pays 1.5% in fees and 3.2% inflation, the other pays only 0.3% in fees. After inflation and fees, the first investor’s real return is just over 2.3%, while the second’s is 3.5%. Over a decade, that gap can mean tens of thousands of dollars.
In 2025, the real rate of return is the clearest lens through which to view your investment progress. Inflation, taxes, and fees are all moving parts that can quietly chip away at your financial goals. By understanding and optimising your real returns, you’ll put yourself in a stronger position—no matter how markets or policy settings shift next.
