First, when it comes to a budget you have to have an idea of what amount of money you are going to make each year, month, week, and even day in some cases. You also have to know how to properly use extra money that was not figured into your budget. It is always better to figure on making less and spending more than making more and spending less. Second, if you struggle with budgeting, then using budgeting worksheets might help you. These can be printed out or just kept on your computer if you prefer. Most of the budgeting worksheets that are out there will break everything down into the categories for the bills that you need to pay. This is very helpful and will allow you to stick to the budget you set up for yourself.
After you have track your spending for a month, you now have the information you need to create a monthly budget. Now you know exactly how and what you spend your money on. If you did not have a surplus of money at the end of the month, you can now see area where you can trim your spending in order to operate you budget with a surplus next month.
