1 I’m not including the car payments because the car is an asset and the the loan is a liability. The correct way to calculate costs is to add the value of your car as an asset, add the value of your loan as a liability (which has a net effect of 0) and only look at the depreciation and interest expense. Depreciation—the difference between the purchase price and sale price is part of the total cost of ownership.

2 I expect fuel costs per mile to drop this year since the price of fuel went down.

3 The insurance rate for the Mazda3 reflects what I paid before getting married. It is much less now that I’m married so that will go down this year but in my next report I won’t be able to split the insurance by vehicle since it doesn’t show up that way on my statements.

4 Depreciation is low because I shopped around and got a very good deal on the Mazda3—about $4,000 less than what Costco offered ($100 over invoice) for the exact same model. At some points last year I could have sold my car for more than I bought it for. However, I expect depreciation to be much higher this year. Depreciation calculated from KBB.

5 The insurance rate for the SHO is what I /would/ have paid had I not been living with my parents… this is higher because my insurance company was 21st (I use Amica now) and they didn’t have very good rates. But because I lived with my parents I paid much less than that. If I remove insurance from the calculations on both vehicles the SHO is $0.54/mile compared to the Mazda3’s $0.28/mile.
