A family budget is not a sum of the income and expenditures but a complex system of planning and risk-taking. There are a lot of things that come with a family budget you are supposed to share the entire budget with your partner, children, or parents. When there is only a couple, the budget is more or less simple for maintenance and more money to do things you love. But on the other hand if they a family it’s a lot to handle such as paying the bills, buying food, clothes, shoes, school supplies, and other things in that nature. It's sometimes difficult but people get through it.
