Your next task is to identify all your expense areas whether they're irregular or not. Set up two columns for each pay period (as shown below); IMAGE NOT AVAILABLE HERE The first column called "Bdgt" is the portion of your income that each expense area will be assigned. The total of this column should never exceed the income you receive for that period. The second column "Used" shows a negative amount and is a record of what has been spent from that period. The beauty of this system is that it will always give you a running balance.
Now we have reached the make adjustments phase, subtract your expenses from your income and if you have some money left over at the end of the month you have got yourself a budget. Realistically most people will not have a workable budget at this point, again it's not really your fault if you don't have a budget, because nobody ever took the time to show you how to set up a budget, much less help you stay on a budget. It doesn't take a rocket scientist at this point to figure out that you should reduce your nonessential spending habits and that's what they usually are is habits, they are your wants, not your needs. Pare your expenses down so you have some money left over at the end of the month and you now have your first monthly budget.
