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.
I'm a fan of MS Excel _ my apologies for those who have issues with Microsoft _ because I find its powerful calculations are easy to manipulate to help me better understand my finances. It doesn't really matter though which spreadsheeting package you use so long as you are able to calculate your amounts effectively. There are commercial budgeting worksheets available but if you want to create your own its a simple process.
