How do you figure out a budget when your pay checks differ from week to week?

Katz,
I wish I could give you an answer which only takes 5 minutes to use and provides accurate information. Unfortunately, that is not realistic.

The foundation of any budget is good bookkeeping. You need to track your income and your expenses. Set up a budgeting worksheet on Excel, or get Quicken. Quicken will be easier to work with, but it will cost about $60.. I listed the categories to start below. Add or delete categories as needed. Each column in Excel should be one month. Each row should be 1 expense category. Make sure to reconcile your checkbook each month. Failing to reconcile your checkbook is like having a condom, but not using it.

There are some items which are a bit harder to budget. For example, you pay for homeowner's or renter's insurance once a year. Take the bill divide it by 12, and add it to your expenses monthly as an accrued item. Some expenses are unpredictable. For example, you know that your car will eventually need an expensive repair, but you don't know when it will happen. Go through your check register for the last 24 months. Add up all the unexpected items and divide by 24. Then enter that amount on your budget each month.

I suggest you get a book called Bookkeeping for Dummies by Lita Epstein. Please don't be offended by the name. For Dummies is a publishing company. They contract with top authors who are both experts in their field and have the ability to put concepts in simple English.
