Some 45 per cent of families with children aged under 18 or who have adult children who are financially dependent on their parents, would run out of cash within a month, according to the calculations.
Insurer Aviva weighed up families' outgoings against their savings. Its findings suggest more than one in five (21 per cent) families would exhaust their savings pots within a month – while a further one in four (24 per cent) of families have no “rainy day” savings to fall back on.
Adding these two groups together, it found that 45 per cent in total could not support their current lifestyle for a month if their main income stopped.

Even by tightening the purse strings, cutting back to the absolute minimum spend needed to support their family, one in three families (36 per cent) could not survive a month unsupported, according to the findings.

The research found that the average UK family has just £2,004 in savings and non-pension investments to keep them afloat compared with £2,606 in monthly outgoings on essentials such as groceries, bills and their mortgage or rent.
It found that only one in three (33 per cent) families could sustain their current spending for longer than six months.
But parents also appeared to be over-optimistic about their ability to sustain their current lifestyle, the research found.When asked how long they could maintain their lifestyle just by dipping into their savings and investments, parents of dependent children typically gave five months as an answer.

Paul Brencher, managing director, individual protection at Aviva UK, said: “Struggling to stay afloat financially is the last thing families need in addition to the emotional turmoil of falling ill or experiencing a death in the family.
