I know there's a few threads going about this topic. I've read them and they've been helpful. I was hoping that a few of you could take a look at the 10 year cost analysis I have drawn up. A little about me: our annual household income is about $75,000. We have no debt but our mortgage. My daily commute is about 90 miles, and I we travel about 35,000 a year. My logic is that the money saved in gas and maintenance would be cover the premium in price that I would pay over an ICE. I hope my spreadsheet is somewhat readable. It shows two different plans. Plan 1 is how I would proceed if we did not purchase a Model S. It shows our current Corolla with a purchase of a used 4Runner. Plan 2 we would purchase a Model S and keep our Corolla. Plan 1, the Corolla would bear the bulk of our miles, and Plan 2 the Tesla. Since it is a 10 year analysis, I figured I would have to earmark additional money for a battery replacement. I have added in $12k in Plan 2 to accommodate this. From what I can tell, I would save $500 a year with a Model S. Spreadsheet: tesla_procon5.xls - Google Drive Thanks for any insight!
