According to this article it’s about the same as paying $2.25 for a gallon of gas. Superchargers are a premium product. Tesla owners do 90% of their charging at home or at work.

What is the life of a Tesla battery and what is the cost of replacement? Is that amortized into that $2.25 a gallon comparison?
Early adopters get to use the Superchargers for free, but current buyers have to pay. I have a couple of pals with 2014 Model S Teslas, one who uses his as a daily driver. The car’s battery pack, like virtually everything else in the car, is monitored electronically by Tesla. His battery is in great shape, Tesla even extended the warranty for him.
In this part of OC Teslas are appearing to be as commonplace as the ubiquitous Mercedes. I haven’t heard any Tesla owner complain about the car so far.
