I have a budget worked out in excel, did it myself.
Categories:
Don't forget to make allowance for for spending money. Everyone needs mad money for whatever, don't be too stingy.
Other yearly expenses I forgot over the years have been magazine/ newspaper subscriptions, gifts for friends/ family, property taxes, registerations, park district fees for yearly pass, etc.
Try and add in other categories like vacation savings, furniture savings, , home manintance, short term and long term savings as well.
Also like a pp, don't use the word budget, because it really should be called a spending plan. Plan where your money is going, what is it doing?
I found it helpful to look back over my check registers to see where my money went. That was a lot more telling than what I think I spend my money. I found out that I needed a thrift store/ yard sale fund....

A bit of a drift thread, but I highly recommend the book "Your money or your life" by Joe Dominguez and Vicki Robin. It really helped me look at money in a new way. It has some budget stuff, but also makes you consider many other aspects of my life and how I deal with money.
Here is a link to about the book

I was able to check it out at the libaray but am toying with the idea of purchasing a copy to own.
