I thought I'd share my budget for the year. It's an annual budget so each month is a little different; for instance, in February (the month shown below) I'm setting aside $800 for our summer CSA share. But this shows what our fixed or predictable income is, the necessities we need to cover first, and then the variables, listed in order of priority so we fund the more important ones first and go down the list. So far, we are fully funded for January and everything but groceries is funded in the needs list for February. Once we finish funding the essential expenses, subsequent income will go to funding variables. We still have some variable expenses outside of that list, so when they come up, I'll fund them with incoming freelance money if possible, or we'll discuss taking something out of one of the other categories if we need to.
I feed this month by month into our ongoing budgeting tool which I call "Number Crunch" or "future checkbook."
