Problem families are costing Royal Borough taxpayers £10.5m every year.
According to a Government report there are an estimated 140 'troubled families' in Windsor and Maidenhead, with each one costing authorities an average of £75,000.
This sum comes from the money spent protecting children in these families and responding to the crime and anti-social behaviour they perpetrate.
The figures come as Prime Minister David Cameron launched the Whitehall-based Troubled Families Team and pledged £450m to help local authorities tackle the problem.
"People in troubled families aren't worthless or pre-programmed to fail," said the PM, whose initiative relies on councils identifying families based on factors such as truanting and crime.
