A budget is simply an analysis of how much money comes in and how much money goes out.
Your public library has information about budgeting and money management techniques. Low cost budget counseling services that can help you analyze your income and expenses and develop budget and spending plans also are available in most communities. Check your Yellow Pages or contact your local bank or consumer protection office for information about them. In addition, many universities, military bases, credit unions, and housing authorities operate nonprofit counseling programs.
Another FAQ Farmer suggests a technique called "Reverse Budget":
Small business financial consultants have been teaching it for years. Basically what you do is make a list of all the expenses you want, vacation once a year, Christmas, yearly mortgage total, car payments, dinner out...you get the idea. Anyways, add that all up and see what you need to make to be happy and avoid crediting fees. Seven out of ten people already make their ideal amount they just don't know because they're not looking at it backwards. If you're not making that amount, find a way to do so. Never limit yourself by the money you make.
