re: Stupid budget question

I sort of accounted for it by just making a slush account tracking goal. As others have said, you're not going to be 100% accurate, since you'll have monthly fluctuations and life events. This works for me so if I come in under a few bucks are saved and if I'm over the next month, it will come from this account. I've made a mental note that if this account reaches say a $1,000, any overage will move to long term savings/investments and on we go.
