I was just wondering what the typical financial situation is for someone that purchases a MS, but wanted to find out in a way where people don't need to divulge their income or other personal information. I thought a poll would be a good way to do it, as the results are anonymous. I also figured coming up with a ratio rather than using raw numbers would make the comparison more useful and could apply across the full price range of a Model S. So I thought of the TTI Ratio (Tesla to Income Ratio) which would be calculated as the ratio of the cost of your Tesla to your annual gross income. To keep things as simple as possible I would set the cost of a brand new custom ordered Tesla or an inventory car that was not sold at a discount at an amount equal to the full MSRP, ignoring any referral bonus, income tax credit, delivery charge, sales or property taxes, etc. For an inventory car sold at a discount because it was used as a demo car or loaner or because it has out of date hardware, the cost should be the actual purchase price, but again ignoring taxes, credits, etc. For the denominator gross income is pretty straight forward, but for anyone that is retired or funds their lifestyle in whole or in part on savings/investments/pension distributions, etc., you should use whatever amount you have available to you annually to fund your living expenses. So as an example if you purchased a brand new MS for $100,000, and you have a job where you make a $100,000/year gross annual income and have an inheritance that provides you with a distribution of another $100,000 per year to fund your lifestyle your TTI Ratio would be 0.50:1.00 since the cost of your Tesla was 1/2 of the amount available to you annually to fund your lifestyle.
