Oh god I’ve gone full tory in this regard recently. My “life admin” spreadsheet has the following tabs:
HMRC Tax Year Calcs - where I work out how much I gotta pay THE MAN and how to avoid paying more than I should.
Bank Balance Tracker - I get paid irregularly so I need to make sure I’m not about to go massively overdrawn so this shows upcoming spends regular and not. Goes well into 2020. Vertiginous.
Worked Days Log - I’m naturally inclined to be lazy so gotta make sure I’m on track to work my minimum target
RENT - actually contains all household expenses now that I live alone an am in charge.
Portfolio Snapshot - ALL MY MONEY. Having cake > eating it
Scottish Widows - value of my pension (depressing)
HSBC Debit, Sainos, Post Office - credit cards and bank accounts with each spend categorised
Mortgage Hypotheticals - how much I could spend on a house based on a few scenarios, like with someone else or not (depressing)
