Hi,
Monthly income - €2,300
Monthly non-discretionary spending - €850
Net discretionary spending - €1,450.
Don't know what you're spending it on Noor, but you're obviously having a good time with it!!
You should be able to live very comfortably indeed on €200 per week, leaving you €650 p/m for savings.
Maybe I'm not reading your post correctly, but I pay virtually your mortgage repayments in rent each month, take home a good bit less than you, max my SSIA, and have a few hundred left to chuck into a savings a/c each month. I have set myself a strict budget of €100 per week, which although tough at the beginning, is easy now, and has been instrumental in getting my finances sorted out.
Try cost cutting by bringing your lunch into work, etc. Also, try to take it easy on nights out - in the past I have been know to burn through up to €100 on a night out - waste of money, unless you like being broke and having a killer hangover!! And please please TRY to max your SSIA!!
