Only 41 per cent of women and 53 per cent of men in Australia are on track to achieving a comfortable retirement income, according to Mercer's latest study.
The study found that Baby Boomers were the least prepared generation in terms of super and that only 16 per cent of Australians made regular voluntary contributions.
Gen X outperformed all other generations with higher incomes and higher levels of voluntary contributions.
Mercer said while 94 per cent of taxpayers earning over $100,000 were on track to a financially secure retirement, the Association of Superannuation Funds of Australia (ASFA) standard for what annual income equates to a "comfortable lifestyle" was relatively low — $59,160 for a couple.
Mercer senior partner, David Knox, said: "The correct investment strategy choice is crucial to ensuring financial security in retirement. Members must also consolidate their accounts and be strongly encouraged to regularly make voluntary contributions".
"Super funds play a critical role in recognising where retirement income gaps are occurring and encouraging underprepared members to actively take control of their financial future," he said.
"Funds must also consider what retirement income is more appropriate for each of their members. Will a high income couple really be happy living off just $59,160 per annum in retirement?"
Knox said the study should act as a warning to both funds and members to act now in order to ensure the financial security of Australians in the future.
Vanguard Super has reported strong returns across most of its investment options, attributed to a “low-cost, index-based approach”.
The fund has achieved double-digit returns amid market volatility, reinforcing the value of long-term investment strategies for its members.
Australian super funds notched a third consecutive year of strong returns, with the median balanced option delivering an estimated 10.1 per cent over the 2024-25 financial year, but an economist has warned that the rally may be harder to sustain as key risks gather pace.
AustralianSuper has reported a 9.52 per cent return for its Balanced super option for the 2024–25 financial year, as markets delivered another year of strong performance despite the complex investing environment.
