Hello,
There are long term, medium term and short term objectives for you here if you really want to change your finances for the better (and to be honest, you really should because your paycheck may not be there for ever !)
Short term:
You have accounted for €900 out of approx €3,300 per month. So thats €2,400 unaccounted for each month, or say €600 per week if you rather.
For one week, keep a small pocket diary and write down everything you have spent your money on because the first thing to do is identify where your money is going - so you can then start cutting back on things you don't need or start spending a little more wisely.
For the second week in that same month, stay in for a full week (don't worry, your social life won't disappear for evermore and you don't have to go anywhere at the weekend etc). It's no big deal, it's only 7-days. Stay in, watch a few movies or read a good book, order in a curry rather than going out for a meal. Again, keep a note of how much you have spent and what you have spent the money on. Whatever is left over from the €600, stick it straight into a savings account immediately, somewhere that is not very easily accessed (i.e. can't be obtained via bank card). Perhaps open a credit union account if you don't already have one and stick it in there.
For the remaining two weeks of this month, put €100 per week into the same savings account. It will only be 15% of your "disposable" income fo two weeks, so it won't hurt you even if you think it will.
Spend those two weeks comparing the list of things you spent your money on during week one and week two, then asking yourself if your spending your money wisely each time you go to spend it:
- could you buy at a better price somewhere else ?
- do you really need to buy at all ?
- is there a loyalty card you could get to earn discounts or rewards from whatever you are spending your money and if so are you using it to get recognition for the custom you are giving them ?
If you follow those steps successfully then in one single month you will have:
- €400 - €500 (or quite possibly more) in a savings account
- a lot more detailed information on what you have been spending your money on
Then you'll be ready to start setting some goals for yourself, start saving regularly and start cutting back on unnecessary expenditure or spending a little more wisely and there's many a good person on here that will offer further sensible suggestions to help you with medium and longer term objectives.
Very best of luck, it's only a month so take a chance you've nothing to lose
