Cost of Driving an EV

My daughter has a Tesla and she does just that. Plugs it in a 120 volt outlet overnight and
it has a full charge the next day. She did get a bill for road use tax from the state since she doesn't have to buy gasoline.
It's not for everyone but its working her.

I'm curious because I have NO idea. Has she monitored the power required to charge it? Just wondering how much that costs over time. kWH would be nice to know since cost would be different everywhere for the same thing.
