I can't access the exact figures while at work but that's a pretty close estimate and doesn't include things like nights out, meals, birthdays, christmas etc.
Couple of suggestions if you're struggling, try shopping at Aldi for things like bread, cereal and things like that instead of doing one bulk shop at tesco or morrisons or where ever! It's much much cheaper and to be honest I haven't noticed the difference between the food from Aldi and the food from Tesco or Morrisons.
Also make sure you put money away each month for an unexpected bill, doing this really saved me the agro of having to worry when my old car broke down!
