You would hate looking at my spreadsheet.
I have just seven categories, and one of them is "Cash/Ent/Food".
- Cash means what I get from ATMs and spend on whatever (the whatever is not accounted for).
- Ent means all entertainment (tickets, etc.)
- Food means anything bought at the supermarket plus whatever is spent in restaurants.
I actually keep very close track of all our spending (within my seven categories) and I always marvel at how others break their spending down into what I would consider sub-sub-sub-sub-categories.
My point is that it doesn't really matter, as long as you know, to your own satisfaction, where your money is going.
