Retirement Savings Adequacy in Australia: Bridging the Gap Between Super Returns and Rising Living Costs

The adequacy of retirement savings in Australia is increasingly under scrutiny as the gap between superannuation returns and rising living costs widens. While Australian superannuation funds have delivered robust nominal returns in recent years, retirees face a reality where essential expenses—particularly in healthcare and housing—are outpacing income growth. This mismatch threatens the long-term sustainability of retirement savings, even as the sector's financial metrics appear resilient.

Superannuation Performance: A Tale of Two Metrics

Australian superannuation funds have demonstrated impressive returns, driven by strong equity market performance and strategic allocations to growth assets. The median Growth fund returned 10.5% in the year to June 2025, with real returns (after inflation) averaging 5.3% annually over the past five years. Industry superannuation funds, in particular, have seen total assets grow at an annualized rate of 14.1% since 2020, reaching $1.4 trillion. High Growth options, such as those managed by Colonial First States and Hostplus, even achieved returns exceeding 12.85% in 2025, buoyed by aggressive exposure to equities and technology-driven sectors.

However, these figures mask volatility. Returns dipped to -3.3% in 2021–22 due to global market turbulence, underscoring the risks of relying on asset classes sensitive to macroeconomic shocks. For retirees withdrawing funds during downturns, such volatility can erode savings more severely than average annual metrics suggest.

Rising Living Costs: The Silent Erosion of Purchasing Power

While superannuation returns have been stellar, the cost of living for retirees has surged, particularly in critical areas. The Living Cost Index (LCI) for age pensioners rose by 2.9% annually in the twelve months to March 2025, outpacing the general inflation rate of 2.1%. Health expenses, a cornerstone of retiree budgets, increased by 6.9%, driven by rising medical costs and pharmaceutical prices. Housing and groceries also contributed significantly, with housing costs remaining stubbornly high despite broader inflation easing.

For context, the average annual living expenses for Australian retirees range between $60,000 and $70,000, encompassing housing, healthcare, groceries, and leisure. Even with superannuation's real returns of 5.3%, retirees must navigate a landscape where essential costs are rising faster than their savings' purchasing power. This disparity is exacerbated by the fact that wage growth for blue-collar workers—many of whom rely on superannuation—has lagged behind inflation, reducing the broader economic safety net.

The Mismatch: A Looming Crisis?

The disconnect between superannuation performance and living costs is not merely numerical—it reflects structural challenges. First, while Growth funds thrive in bull markets, retirees often shift to more conservative Balanced or Income options as they near retirement. These options, though less volatile, delivered 8.72% annual returns over three years to June 2025, still trailing the 5.3% real return of Growth funds. Second, the concentration of returns in equities and technology exposes retirees to sector-specific risks, such as AI-driven market bubbles or geopolitical disruptions.

Moreover, the $60,000–$70,000 annual expense range implies that retirees must generate consistent income streams to maintain their standard of living. A 5.3% real return on a $500,000 super balance would yield approximately $26,500 annually, leaving a significant shortfall unless supplemented by pensions or other assets. For those without substantial savings, the gap becomes insurmountable.

Implications and the Path Forward

The growing mismatch demands a recalibration of retirement strategies. Policymakers must address systemic issues, such as improving access to affordable healthcare and housing, while also encouraging higher superannuation contributions or tax incentives for retirees. On an individual level, retirees should diversify their investment portfolios to balance growth and stability, leveraging annuities or income-generating assets to hedge against inflation.

For the superannuation sector, the challenge lies in aligning investment strategies with the realities of an aging population. While high Growth options offer attractive returns, they must be paired with robust risk management frameworks to protect retirees during market downturns.
