Another way of controlling your finances is to set strict limits on your monthly spending.
I use a spreadsheet.
It's organised so that each column is my monthly spending and income. I have set it up so that spending are additions.
At the bottom of each column is the sum of all spending for the month.
I also have a calculation to estimate how much I am predicted to spend in the year based on the monthly totals.
It's all updated every time I add a spending figure.
