About £600 a month after mortgage and bills, 2 adults, 2 DSs, 2 ducks, 1 chicken, 1 cat, 1 cockatiel.
We then spend £150 on fuel and as little as I can get away with on shopping! I love the Asda Price Guarantee, I always "win" a couple of quid back. I think they discount their big brands, but I go for the cheapest-per-100g so I mess up their calculations.
I get hand-me-down clothes from DP's mum who buys stuff in optimistic sizes and then passes on the things she can't wear. When people ask "What do you want for your birthday/Christmas?" we always answer "clothes/vouchers/money please".
No savings, unexpected expenses get put on the credit card (naughty, about £2000 owed and pay £150/month in bills) but as long as we're not going backwards I reckon we're winning. We own a tent, so any holidays mean a bigger fuel and shopping bill for the month but that's all!
Trying not to feel jealous of some people's disposable incomes, but the saying goes "You live to your means" so I expect no-one feels well-off unless they've just won the lottery. :)
(Plus, for a couple of years I earned less than my mortgage/bills and lived off an equity release whilst I desperately tried to hold on to my house... see, could always be worse!)
