Turning 18 makes a teenager a legal adult, but it does not automatically make them financially independent. With housing, education, groceries, transportation, and insurance taking sizable bites out of young workers’ paychecks, many families are reconsidering what adulthood at home should look like. Recent research from Pew Research Center found that 57% of 18-to-24-year-olds live with a parent, so remaining home after high school is hardly unusual. The debate over whether a teen should pay rent after 18 is really about balancing responsibility with the opportunity to build a financial foundation. For many households, the best solution may fall somewhere between completely free housing and charging market-rate rent.
