Begin by listing your income for the month. This should include any paychecks you receive, as well as income from other sources like child support or investments. If you have a business, you should include the amount that you pay yourself out of the business each month.
If you already own your home or you're locked into a lease, you're pretty much stuck with that ũ귔 payment. Consider relocating when your lease expires to make your budget more manageable or take a look at your other "needs" to see if there's a way that you can reduce any of them. Maybe shop for more affordable insurance or transfer the balance on that credit card to one with a lower interest rate so your minimum payment drops a bit. Your goal is to be able to fit all these expenses into 50 percent of your take_home after_tax income.
