Rent or mortgage, utilities, phone service, insurance- including car, home, and health, taxes, other health-related costs, gas, basic food needs, legal obligations like student loans, anything that you have a contract to pay like cell phones, gym membership, or satellite tv and other legal obligations like child support.
Savings is a little misleading here because this also includes any other debt you may have. Not only are you looking at things like your 401K contributions, but you are also looking at you credit card payments and anything extra that you pay on your other must-haves.
This could be anything that you want. From a pedicure every three weeks to a trip to Paris. From a Grande Soy Latte to a Michael Kors purse. The theory is that life is not sustainable if you aren’t having fun while you do it. I found cable TV to be a want, as long as you don’t have a contract with the cable company.
