I think I pay out around £1100 a month usually, a little more at the moment cause I'm subsiding the mrs as she hasn't got a permanent job justnow. That's just bills no food or petrol etc... I think about a grand is reasonable, I like to be able to go out whenever i like which is usually twice a week on the piss, cinema, out for meals, go karting (new hobbie) etc..... plus try and save a bit as i go along. The more you earn the more you spend though, If i had a good month 3.5-4k I still usually end up with the same amount just before i get paid again.
