In order to create a budget, we must record all of our sources of income. This may include all the income that we make from our jobs, as well as income that we may make each month from savings and investments. It is important to gather all of your investment and financial statements, which will show this income on them. Next, we look at all of our expenses, and record each one in a column that we pay regularly. You may want to look at all checks that you have written over the past few months, as well as credit card expenses, and try to group them all into various categories.
