EV Charging: Gasoline Price Equivalent Index

Discover how EV charging costs stack up against gasoline prices


Stable Auto monitors thousands of public DC fast chargers and level 2 chargers across the U.S. Amidst ongoing consumer confusion about charging costs and their impact on total cost of EV ownership, we’ve created a gasoline price equivalent index. This index translates electric vehicle charging costs into a familiar metric: gasoline prices. By comparing the cost of gasoline with the cost of charging, our index helps drivers understand the financial benefits of switching from gasoline to electric.
