I just downloaded 3 months worth of spend, after tax and pension/workplace sharescheme:
28% savings
17% "household bills"
6% groceries
6% nights out (where we've paid by card, so read as eating out)
3% takeaway/fast food
5% fuel for cars
i've also got irregular spend: 15% on holiday, 14% cash. Holiday is one-off as we had the balance to pay, and the cash is things like booze on nights out, pennies for lunch, and im not sure what else.
This has actually shocked me somewhat.
