Under 40s are the most likely to have lost superannuation, but many are doing nothing about it, according to Westpac.
Westpac's Lost Super Report found almost two-thirds of under 40s surveyed are likely to have lost super, but more than half of those under 40 are not making any attempt to recover it.
Younger generations were also more likely to 'not know' if they had any lost superannuation in the $17.4 billion.
But the report found there is a lack of engagement around retirement planning across all generations and many Australian's underestimated the amount they would need to retire on.
Fifty-two per cent of Australians said they would need less than $600,000 to retire comfortably, but according to Westpac Group head of superannuation Melanie Evans, women would need $740,000 and men would need $680,000 for a retirement with a yearly income of $45,000.
Westpac found younger generations have greater job mobility, with 42.2 per cent of under 40s saying they have had more than four employers over the past decade - a likely cause of lost superannuation.
Evans said while it was easy to lose super through changing employment and address, the process to reclaim was simple, and Westpac had opened their branches to assist Australians, two-thirds of which said they would like more help to locate lost super.
Minister for Financial Services and Superannuation Bill Shorten welcomed the initiative, saying it complemented the Government's work to consolidate super accounts, including recent improvements to the SuperSeeker website.
