If you can sign up to restaurants' mailing lists, then you may get regular vouchers to spend in their establishments, and save on going out for meals. Ideal for me as I love going out for meals.
Tracking your spending is the key to successfully managing your budget. Even buying small items every day mounts up. If you spend £1 a day on a newspaper, then that is £30 or £31 a month. Maybe choose just to buy a newspaper at the weekend.
Track every pound you spend. Every pound your earn has to have a place. Make sure you know where it is!
If you can cut down on say a coffee that you buy out each day, that will save you approx £75 per montth. Imagine what you could do with that!
Pay in cash and don't rely on your credit cards. With cash you can physically see what you are spending, whereas with credit cards, there are no visuals.
Set a specific financial goal by saying, for example, I am going to save £100 this month. It gives you a clear, definable goal to work with, and is much more attainable.
Save 10% of any amount coming into a separate account. This will give you some breathing space should a big bill come in unexpectedly.
Check on how much you spend on going out, entertaining, etc.
Put some money away for Birthdays and Christmas. These events will always come around at the same time every year, so there is no excuse to not have the money to pay for these. It is a lot less stressful to have some money saved each month towards these.
And finally one that I love. Put £1 or £2 in a pot every day. That's either £365 or £730 by the end of the year to treat yourself with! Result!!
