As a parent, you might struggle with when and what to teach your children about money management. Is five too early to earn an allowance? Should you share the family budget with your children? When should teens learn about credit? These are all important questions, and it’s often not easy to know the answers. Kids have different levels of interest in financial education. But research tells us that by the age of five most children understand money and what it can do. The information below offers more specific guidelines for different age groups. Again, these are just guidelines. What decisions you make about when and what to teach at home depend on your family situation, household budget and how comfortable you are in the role of teacher.
