Household Expenses vs. Personal Expenses
In general, household expenses include rent or mortgage payments and utilities. These are the bills that must be paid every month no matter how many people live in the residence. Utilities can include electric, natural gas or propane, water, sewer, and trash. Other monthly expenses could include a telephone, cable/satellite, or Internet bill. Those "others" could be up for debate in some households.
Food expenses could be considered household or personal expenses. If everyone in the residence is responsible for his own meals, including doing the dishes, the ground rules should be laid out in advance. In this situation, each person should also buy their own dish detergent and have their own location for food storage. However, if the group decides to share food expenses, extra steps such as group menu planning and shopping will be necessary.
Personal expenses include car or public transportation costs, clothing, entertainment, dining out, and travel.
