On a whim, I was trying to calculate the depreciation of my excellent condition, December 2018, Blue M3 LR AWD 18" EAP white interior with 14k miles, via offers from Vroom, Carvana, and Shift, and it comes out to be about 12k/year.
My compare method is the offers from those websites vs. the sticker price on my MVPA before sales tax.
Wondering if that sounds about right, or if it should be higher/lower?
Anyone else tried calculating their depreciation using similar web sites to get an idea?
Your "compare" is wrong, unless you didnt get the 7500 tax credit..
I bought a very similar car, except mine is the performance model so was more expensive than yours. My MVPA says 71,500 before taxes. That includes EAP. I am not sure what your MVPA number is, but its likely lower than mine.
We both got a 7500 tax credit so subtract that (I dont want to hear anything about "thats mine, it doesnt count" etc. It DOES count in your cost of the car and depreciation, especially since new cars do not have access to that credit.
You are also in the Bay area in CA so I am virtually certain you applied for, and received the california tax credit, as there were less restrictions then (as I did)... unless your household income is such that you didnt qualify for that which is I believe over 300k.
So, you take your MVPA, subtract the 7500 tax credit, subtract the california rebate, and THAT is your cost of the car.
In my case, its 71,500 minus 7500 minus 2500 for the California rebate, and minus about 1500 in other rebates I got. Maybe you didnt get the other 1500 but you almost assuredly got the 7500 + the 2500. So subtract 10k from your MVPA number and thats what your cost was.
Now, if you want to figure out the depreciation by carvana offers instead of private party ones, go ahead. But it isnt anywhere near 12k a year. In my case it looks like this:
71,500 minus 7500 minus 2500 = 61,500 my cost pre tax for a Model 3P with EAP. Car cost new right now = 64,990, so it actually cost me less, not "20k-25k more" like some people like to say. So if my cost is 61,500, I could sell this car easily for 47k, but could probably get up to 52k for it if I waited on the right buyer.
Lets go with 47k thats 14,500, or 659 a month which doesnt count me actually using the car as well.
