Use
Money Manager Ex ...
Its a small application that you can download from the net for free.
It includes a budget,bank account manager and plenty of reports.
What you do is,download all you transactions you made from you internet banking and import it into this little app. They you work through all your transactions and categoriz them. (app includes almost everything in its list of categories) You can also add manual transactions if you work with cash.
Then with the reports you can see where your money is going.
Next is to setup a budget. You do this by budgeting for things in the category list.
Another neat thing it has is a "repeating transactions" function. You save all your repeating transactions with it and then it will remind you of up and coming payment within the next 2 weeks.
After about 3 months will start to see where your budget is falling short and where you have over budgeted.
The trick is to keep the application up to date will all your transactions. Its also helps to do it weekly while you still can remember where your money went and categorize it properly.
Well I hope this can help. It really helped me.(I have about 6 bank account including a Credit card,transactional account and a few savings account)
Last but not least... It can be run from a USB memory stick making it very,very mobile.
