Average return is one of the most important concepts for Australian investors in 2026. It helps you gauge how your investments are performing and set realistic expectations for future growth. But knowing how average return works—and what it doesn’t tell you—can make a big difference to your results.
In a year marked by shifting market conditions and policy updates, understanding average return is more important than ever. Whether you’re investing in shares, property, superannuation, or managed funds, knowing how to interpret average return can help you make smarter decisions and avoid common pitfalls.

What Is Average Return?
Average return is a measure of how much an investment has earned over a set period. It’s a simple way to summarise performance, but there are different ways to calculate it. The two main types are:
-
Arithmetic Average Return: This is the simple mean of yearly returns. It’s calculated by adding up each year’s return and dividing by the number of years. While easy to work out, it doesn’t account for the effects of compounding or the impact of losses.
-
Geometric (Compound) Average Return: This method takes compounding into account. It shows the average rate at which your investment would have grown each year if the returns had been steady. Financial planners and fund managers often use this figure because it gives a more realistic picture of long-term performance.
Example:
Suppose you invest in a fund that returns 10% in the first year, -5% in the second, and 15% in the third. The arithmetic average is (10 + (-5) + 15) / 3 = 6.67%. However, the geometric average will be slightly lower, as it reflects the impact of the negative year and compounding. This distinction matters when you’re planning for the long term.
What’s Influencing Average Returns in 2026?
Several factors are shaping the average returns Australian investors are seeing in 2026:
Interest Rates
The Reserve Bank of Australia’s cash rate has remained steady through the first half of 2026. This has kept deposit rates higher than in previous years, but it has also made borrowing more expensive, affecting property and business investment.
Superannuation Changes
Recent adjustments to superannuation rules—including an increase in the super guarantee and changes to contribution caps—are prompting funds to review their asset allocations. These changes may influence the long-term average returns for superannuation members.
Market Volatility
Global events and sector-specific shifts, particularly in technology and resources, have contributed to more unpredictable annual returns. While Australian shares have delivered solid average returns over the long term, recent years have seen more ups and downs, which can affect short- and medium-term averages.
Property Market Trends
After a period of strong growth, property prices in many parts of Australia are rising at a slower pace in 2026. This means average returns from residential property may be lower than the long-term average, at least in the short term.
Tip: When comparing managed funds or super options, focus on their 5- and 10-year geometric average returns. This gives you a clearer sense of how they’ve performed across different market cycles.
The Limits of Average Return
While average return is a useful starting point, it doesn’t tell the whole story. Here are some important limitations to keep in mind:
Volatility Isn’t Shown
Two investments can have the same average return but very different risk profiles. One might have steady, predictable returns, while the other swings wildly from year to year. Looking at measures like standard deviation or risk-adjusted return can help you understand the ride you’re signing up for.
The Sequence of Returns Matters
If you’re drawing down on your investments—such as during retirement—the order in which you experience gains and losses can have a big impact. A large loss early on can be much more damaging than the same loss later, even if the average return is the same.
Inflation Reduces Real Returns
Inflation eats into your investment gains. For example, if your portfolio returns 6% in a year when inflation is 3.4%, your real return is only 2.6%. Always consider the impact of inflation when assessing your investment performance.
Fees and Costs
Management fees, brokerage, and other costs can significantly reduce your actual returns. A fund with a higher average return but steep fees may leave you worse off than a lower-return, low-fee alternative.
How to Use Average Return in Your 2026 Investment Strategy
Understanding average return can help you make better decisions, but it’s important to use it wisely. Here’s how:
Set Realistic Expectations
Use recent average returns for the asset class you’re considering, rather than relying on figures from previous market booms. This helps you avoid disappointment and plan more effectively.
Compare Apples with Apples
When reviewing funds or super options, look at their geometric average returns over 5 and 10 years. Compare these to relevant benchmarks to see how they stack up.
Factor in Fees
Always check the fees associated with any investment. A higher return can be quickly eroded by high management or transaction costs.
Diversify Your Portfolio
Average return can help you blend different asset classes—such as shares, bonds, and property—to achieve a smoother overall result. Diversification can reduce volatility and help you stay on track toward your goals.
Rebalance Regularly
Market movements can throw your portfolio out of alignment with your target risk and return profile. Reviewing and rebalancing your investments periodically can help you maintain your desired mix.
Practical Example: Reviewing a Balanced Fund
Imagine you’re considering a balanced managed fund. You check its 5-year geometric average return and see it’s around 6% per annum. The fund’s fees are 0.5% per year. If inflation is running at 3.4%, your real return after fees and inflation is about 2.1% per year. This gives you a more accurate picture of what you might expect going forward.
Making Sense of Average Return in 2026
Average return is a valuable tool for Australian investors, but it’s only part of the picture. By understanding how it’s calculated, recognising its limitations, and factoring in costs, volatility, and inflation, you can make more informed decisions about your investments.
In 2026, with markets and policies continuing to evolve, staying informed and regularly reviewing your portfolio is more important than ever. Use average return as a guide, but always dig deeper to ensure your investment strategy is robust and suited to your goals.
