You need to first work out how much your incoming and outgoing is!
Do it with a spreadsheet either microsoft or online with google.
Record ALL bills, receipts etc and categorise them.
This way you can monitor your outgoings.
As suggested by the forumers, getting good deals will help reduce your outgoings. You can monitor the spreadsheet on a monthly basis and adapt your lifestyle.
You need to put in some effort to do proper budgeting.
Cheers
