Many children first learn the value of money by receiving an allowance. The purpose is to let children learn from experience at an age when financial mistakes are not very costly. The amount of money that parents give to their children to spend as they wish differs from family to family.(20)In any case, parents should make clear what the child expects to pay for with the money. At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance. Many experts in child-rearing say it is not a good idea to pay your child for work around home. These jobs are a normal part of family life.(21)Paying children to do extra work around the house, however, can be useful. It can even provide an understanding of how a business works. Allowances give children a chance to experience the three things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want, or they can save it.(22)Saving helps children understand that costly goals require sacrifice: You have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing.
