I did this last week and am going to find it an immense help in sticking to budget for the following 14 months and onwards.
If you know Excel, you know you can set it up to do calculations for you.
So I set one up with my basic salary going in and all regular monthly outgoings going out until the end of December 2008. All the way down the right hand side is a total of what I have left.
Then I sat and worked out when I would need to spend extra - birthday presents, etc. I entered a budget for the month before the extra was required. Then all the way through this I kept checking the amount left over at the end of any given month.
By doing this, I figured out that if any extra expense in say June was going to take me over budget, if I cut back on what I allowed myself for spending money in Jan, Feb, Mar, etc, then that takes care of it.
I also have on the same spreadsheet a list for my contingency fund and for my car expenses. As money is added in the amount goes up and if I spend any it goes down, showing me exactly what I have at any given time. By doing it this way, if it shows that I'm going to be short for anything, I can again, rework my personal expenditure to cover the shortfall.
I found that by looking at it over a yearly basis, rather than going from month to month, I can plan better. No use finding out I spent too much in January in April![:D]
All I've got to do now is stick to it.
Odd thing though. I looked at what the total of my contingency fund and the christmas savings fund and the car fund if I didn't have to spend any and now I don't want to spend any. It'd be over 2 grand!!!! Why, after years of spending money I don't have I now don't want to spend the money I will have, I don't know. It'll kill me to have to pay my car tax this year[:D][:D]
