UK parents are being forced to delay retirement to meet the increasing costs of raising children, a study suggests.
A survey of 1,500 parents of children aged 18 and above by the Child Trust Fund provider, The Children's Mutual, found 57% of participants have "no choice" but to retire later.
Four in 10 (43%) expect to work up to five years longer than they wanted because of the cost of their "adult" children.
Almost 10% of parents believe they will now be forced to work over a decade longer with some abandoning the notion altogether.
Eight in 10 (79%) of participants in the survey claim their ability to save for their retirement has suffered as a result of the unplanned financial support needed by their children.
About a third of those (32%) suggest it has been significant.
"Parents of today's young adults face an unenviable choice - secure their retirement or fund their childrens' futures," says David White, chief executive of The Children's Mutual.
"Despite their best intentions, our research shows that for millions of Britons adequate provision for both is currently well out of reach."
