According to Do your parents still pay for things? Maybe a phone bill? Or car insurance? or Maybe a whole ass vacation! The financial advisors at Bankrate conducted a survey to determine what age you should stop relying on your parents to pay for things. The survey concluded that most people think kids should start paying for their own things by the age of 20, and that includes their flights and hotels on vacations.
Otherwise, the parents retirement savings might be in jeopardy.
