Cost depends on local electricity prices. In Bay Area, it would cost $21-25

Correct. Here in the DC Metro area, we pay about $.15 per kWh.

"San Francisco area households paid an average of 26.3 cents per kilowatt hour (kWh) of electricity in September 2021." [1]. The standard Model 3 has a 50kWh battery, so the cost is roughly $13. If you charge between 23:00-07:00 the cost is reduced to $7 [2], though presumably that incurs the cost of installing an extra meter. It would be $9.50 sticking with a single meter for house + car. (For what it's worth, in Denmark the lowest I'm charged is currently double the night rate for PG&E, although the peak day rate is similar. It varies depending on demand and how windy it is forecast to be [3]. But petrol is $2.10/L, so the other commenter's 100L car would be $210 to fill — though at 12.5L/100km, it's pretty inefficient. New vehicles in the US use 9L/100km, in the EU new vehicles average under 5L/100km.)

  [1] is not a good measure, because of low income subsidies not everyone qualifies for. I live in the Bay area, and I pay 35-41 cents/kwh in summer. Now if I charge during the nights with the EV plan, I get preferential price of 14 cents/kwh but that makes my day time use (for other things) that much more expensive. Sorry, I didn't mention I drive a long range model 3, and quoted the price for it, not the parent's mid range.
