When you open the budget worksheet, you will see an area to enter your expense line items. It is important that you do not delete or add rows or columns to this area of the model.  If you delete or add rows or columns, the model will not return accurate results.  This section is broken into two areas.  The top area is for entering Fixed Expenses, and the bottom area is for Variable Expenses.

 

To add an expense, first decide whether the expense is Fixed or Variable.  Then go to the appropriate area and simply type over the item description and enter the annual amount of the expense.  If you do not need the additional spaces, just delete the description and the annual cost.
