hey neltron,
like everyone has pointed out, obviously budgetting is dependant on lifestyle but i think your guess seems reasonable.
one of my mates from work emailed me his rough monthly budget last month and i'm planning on living within the same means. we're both in our twenties living with our girlfriends (ahem, sorry, 'wives').
Rent – Circa 9,500 Dhs
Mobile phone – 200 Dhs
House Phone – 115Dhs
Television – 190 Dhs
Internet – 190 Dhs
DEWA – 200 Dhs
Food shopping – 2,000 Dhs
Going out – 4,000 Dhs
Total = 16,395 Dhs
I think as a general figure, 16,000 - 17,000 per month for a couple in a 1 or 2 bedroom apartment (depending on area obviously) is a reasonable budget - and that's including beer money!
Nobody really seems to have given you an answer but i think you're in the right ballpark.
If anyone thinks that budget is unrealistic please feel free to offer some constructive comments!
