Estimated car expenses - verified

Last week I had some serious car servicing and insurance expenses. I decided to check my total cost of car ownership estimates.

I'm 99% city commuter so before I bought a car, besides well visible costs like car price, insurance etc., I had checked couple of factors like fuel consumption and estimated car servicing cost.After spreading all cost for next 5 years my calculated total was about 2650 euro per year (about 3850 $).

Two years later I have more precise data, like servicing invoices, fuel consumption history etc., excluding occasional fees like parking and other. Simple recalculation in spreadsheet and it looks like my average cost of car ownership will be about 2500 euro/year during last 2 and for next 3 years. It looks like my estimate was quite good. I should include predicted car selling price for example after 5 years, but it's not the point for now.

Here are biggest and most important chunks to consider in calculating car TCO:
- initial car value 47%
- insurance 24%
- fuel 20%

Maybe I should think about rolling car cost calculator based on that experiences. I wish all my budgeting estimates will work with that accuracy.
