I keep my household budget in a simple spreadsheet.

I don't track my daily spend at all. Instead, I have a personal account for daily/casual spending and use that. All other money goes into a different account. This way, the budget item is the amount of money I put into the "daily" card every payday.

But my daily/casual spend is really stable from day-to-day so it doesn't need tracking. I already know what it is. Others may have more volatility to track.
