To get started, type the month in question in large print at the top. Next, you need to type (also in large font) how much money you make each month. So, if this is a four week month, you want to take your weekly paycheck and add it four times. Next, you need to go through and create a column with your expenses. You need to start with the necessary items first.
The great thing about personal budgeting spreadsheets is they can easily be modified to fit your budget. You can enter the exact categories you use monthly for your income and your expenses. These categories can be really detailed such as having individual credit cards listed by name or they can be broad such as having one group named credit cards for all your credit card bills.
