Does anyone have a calculation method to figure out the actual cost per mile? I know the KW cost of my electricty at home.

Wh/mile x KW cost per hour / 1000

So if you are driving at 350 Wh/mile, x 11c/KWh /1000 = 4c per mile

should have said $/KWh rather than KW cost per hour, but same calc.

I think someone had a spreadsheet somewhere that did some cost calculations. Here are some other costs that go into the $/mile.

Tires at $800/set every 20,000 miles would be 4c/mile.

Insurance at $1500/yr and 20,000 miles per year would be 7.5c/mile.

Annual service at $600/yr and 20,000 miles per year would be 3c per mile.

If the car depreciates $50,000 over 100,000 miles that would be 50c per mile.

You can also go to the "Controls" tab and look under the "trips" folder. It will tell you how many miles you have gone since you last reset the trip odometer, as well as how many kWh you used to drive those miles. You can then use the cost of electricity from your provider to figure out your $/mile.

There are lots of moving parts to consider here. For one, just calculating your cost for energy is a useful exercise. Remember too that there is (according to other sources on these forums) about a 15% loss between your wall socket and your car. So if the car says you used 100 kWh, you probably used about 15% more than that from the electric outlet in your garage.

As other posters alluded to, there are other costs that you need to consider as well, depreciation and maintenance being the main ones.

I happen to live in a state that has a very generous PEV (Plug in Electric Vehicle) rate plan so super off peak hourse cost 1.3 cents/kWh.

I started another thread about this very same subject just a few weeks ago. You can look at it here for some interesting perspectives:

Don’t forget to factor in charging inefficiencies.

Charging inefficiencies are trivial, since the actual electricity cost to operate the car is trivial... a percentage of a small number is a tiny number. Tires, insurance, and maintenance are all bigger than power; the BIGGEST factor by far is depreciation.

If you know how much electricity you used for charging in a month, and how much it cost you, then just divide by how many miles you drove in that same period, and viola you have $/mile

Just looking at electro cost is relevant when comparing to cost of gas since all the other factors also apply to an ICE. Then, how do you factor in the value of zero emissions? Big factor in my mind, even if my contribution (actually lack of contribution) is seen by many as minimal, but we have to start somewhere.
