re: How do you and your SO budget?

We use an excel spreadsheet broken down weekly. We get a paycheck weekly (both of us are paid every two weeks, but on alternate weeks) so this works out very well for us. Typically I lay the rough budget out and then get her input.

I start with the take home, our recurring bills are already slotted for a particular week of the month to be paid. Gas, food, daycare/school and savings are pretty much the same week to week. Any special exspenses are added in and any left over at the end of the week is shifted to savings or added to the mortgage payment.
