Of course, now you must differentiate between which expenses are "needs" and which are "wants." Basically, any payment that you can forgo with only minor inconveniences such as your cable bill or back_to_school clothing is a want. Any payment that would severely impact your quality of life, such as electricity and prescription medicines, is a need.
Once you have a list of your expenses and your income, you will need to compare the two numbers. Your expenses should less than or equal to your income. If you have additional money after you plan your budget, you can add it to the categories for your financial goals like getting out of debt or building an emergency fund. If you have more expenses than income, you will need to find ways to cut back on your expenses. Start by cutting money from your categories in the luxury section of your budget. You can also work on ways to increase the amount you earn.
