We break it into different costs to be paid via bills (must be paid that month)
Utilities
Phone bills
Mobile phone bill
Credit Cards (in our home different credit cards have different uses/pay for different things – my wife says its for the points?!)
Then there are fixed costs
Mortgage
Insurance
ADSL
Parking fees
Kindergarden
What I did was create a flat excel file for all expenses and tabbed it into different sheets.
In the personal spending sheet I have an entry in rows for each day of the month. Then in columns I have expenses including for fruit, breakfast, lunch, MRT, bus, taxi, beer, dinner, coffee fruit and miscellaneous. Miscellaneous can be for things like buying a hot dog in the 711, parking fines, or green tea at the tea shop. I always enter a comment for the miscellaneous items to keep track of what these were on a particular day. New fields can be added as needed
I have total for each month, total for the year, rolling average cost per day, rolling average cost per item per day. This updates each time you enter a value. Not that complicated but I set myself a target for each month and try to keep within budget. Looking back at spending a half a year ago, you’d be surprised how much money you just burn or waste - on taxis instead of MRT or bus, on beer on coffee!
I think it is good and useful to keep track of ALL the money you spend. It shows where the money goes and would be very useful if you needed to do some tightening of the belt at a later date. You would know where you could cut and how it would impact you
Total cost for us per month is about NTD100K
I also created tracking matrices within different sheets for weight, blood pressure, excerise time per week. More can be added as need be. Measuring things forces you to get things done. So I have learnt in the field of quality. Besides I like measuring and analysising things
Another sheet is where I keep all my things/tasks to do, wish lists, deadlines etc. MS Outlook or MS Project just does not do it for me
