Miles Per kWh
Definition
The EV equivalent of miles per gallon — how many miles an EV travels per kilowatt-hour of energy consumed. Typical range: 3–4 mi/kWh.
Why is Miles Per kWh Important?
As electric vehicles transform transportation across the United States, understanding Miles Per kWh is essential for making informed EV ownership decisions. Whether you are comparing models, planning road trips, or evaluating long-term savings, this concept directly impacts your EV experience and total cost of ownership.
Our EV calculators help you quantify these factors, enabling confident comparisons between electric and gas vehicles and optimizing your charging strategy for maximum efficiency and savings.
What is Miles Per kWh?
Miles per kWh (mi/kWh) is the EV efficiency metric — how many miles an EV travels per kilowatt-hour of energy consumed. It is the direct equivalent of miles per gallon (MPG) for gas cars. Higher mi/kWh = more efficient = lower cost per mile.
