Teenagers approaching the financial responsibilities of adulthood are "heavily influenced" by their own parents' good and bad money-saving habits, research by a Government-backed body has found.
Two thirds (68%) of 15 to 17-year-olds surveyed for the Money Advice Service (MAS) whose families put money aside for emergencies said they also try to save cash themselves.
But less than half (47%) of young people whose families do not save for an unexpected bill put money away for a rainy day themselves.
The MAS, an independent body offering free money advice which was set up by Government, also found that 53% of teenagers from families who manage to pay their bills or loans find it easy to live within their means, but this figure drops to 29% among young people whose families struggle to keep up with their outgoings.
Researchers said the findings could not just be explained by some families being better off financially than others. They said young people tend to receive similar amounts of pocket money across income brackets.
The study said: "T hose who grow up in a family where they do without certain things because they can't afford them do not appear to be less financially capable as a result."
Caroline Rookes, CEO of the Money Advice Service, said: "We know our money habits are formed very young, and once formed extremely difficult to shift.
"But I am struck by how heavily a young person's money management habits are influenced by their family's past and present financial behaviour."
Previous research by the MAS suggested that most children have formed their money habits by the time they are seven years old, an age when they can count out money and know that it is used to buy goods.
More than three quarters (77%) of teenagers in the latest study said they find their parents' financial advice particularly helpful, while 12% named friends and 8% named teachers as good sources of advice.
But the MAS also said that "worryingly", one in six (15%) 15 to 17-year-olds do not seek help from anyone on money matters at all.
Ms Rookes added: "The good news is that in many respects, young people are already recognising some important aspects of money management, such as saving for future events.
"But it is clear that there is a huge amount for us, collectively, to continue to do, both with parents and young people themselves, to help them prepare for the financial challenges of adulthood."
The research also found that while three fifths (60%) of 15 to 17-year-olds said they keep track of their spending, compared with a bigger proportion (86%) of adults, young people are more likely than adults to save regularly.
Almost two thirds (63%) of more than 1,000 15 to 17-year-olds who took part in the research said they save regularly, compared with just over half (53%) of adults.
Common reasons given for saving among teenagers included "one-off" purchases, driving lessons and to cover university costs and training.
As the Government's landmark automatic enrolment reforms roll out to enourage more people to save into workplace pensions, four fifths (82%) of young people agreed that it is better to start saving into a pension aged in your 20s than in your 50s.
Financial education will be placed on the national curriculum for secondary schools in England from next year, following lobbying by charities and consumer campaigners.
Tracey Bleakley, chief executive of financial education charity pfeg (Personal Finance Education Group), said: "Parents have a key role to play in teaching their children good money habits. As a society we have to work together to make financial education like learning to read - to be most effective, it has to be taught at school and in the home as well.
"Financial education's new place in the national curriculum for secondary schools from next September is a big step in the right direction - but much more needs to be done.
"We know from the Money Advice Service's previous research that financial habits are formed by the age of just seven years old. That's why we need to see financial education introduced in all primary schools, as well as at secondary level.
"Until we reach a point where money management is taught in every school in the UK, we run the risk of allowing young people to enter adult life ill-equipped for the financial decisions they will face."
