Well the loan is at a fixed rate so I cant pay off more even if I wanted to but maybe I could ask the bank about it, they may charge me more though
Certainly worth looking at and crunching a few numbers on. If you can save by accelerating the payments (including any additional fees levied), it'd be worth it in the long run.
Do consider what level of 'emergency fund' you might need/want to have available. If you've no dependants etc. you might be happy with none, but it's hard to put a value on peace of mind so figure out what is right for you.
regarding entertainment l like a few beers with my friends at the weekend, maybe a trip to the cinema and 1 chinese a week, im not sure whats a reasonable amount to allow for entertainment a month
You've two options there, depending on how you want to look at it.
Figure out how much you wish to save, then match your social life to match the budget (higher savings) or else figure out what you're happy to allow yourself to spend (you're only young once and from a financial point of view you're not 'in trouble') and save the rest.
It's hard for anyone else to do figures on those. For a 'few beers at the weekend' you could be talking about +€90 (club, taxi, beers, chipper, etc.) or closer to €30. Cinema probably the guts of €20 including snacks, Chinese in the region of €15... so probably looking at ~€300 - €400 on entertainment as a realistic budget? (you could obviously cut this down greatly if saving is a priority or spend far more if you wished to)
So €650 for the 'fixed' costs. €400 on the entertainment. Leaves €1450 for food, incidentals and savings. Again, your bills will depend on how thrifty you are/wish to be. A weekly spend could vary hugely depending on your personal choices on where to shop, what to buy, etc etc. Going for a target of €850 savings as suggested by dmos earlier would seem a decent level and can be increased/decreased as you see fit over time.
