re: How do you and your SO budget?

Wife built an Excel spreadsheet with all of our bills broken up into first half and second half of the month, and which bills are paid from her LLC. Then we broke down exactly how much money I bring in, how much she needs to supplement and how much we budget for 'play money'. Everything above & beyond goes into savings/retirement. We just revisited our expenses and cut out some of the unnecessary expenses to bolster savings a little more.
