EV vs Gas Cost by State (2026)
Your electricity rate decides whether an EV saves you $400/year or $1,400/year. Washington at 10¢/kWh is a different calculation than Hawaii at 44¢/kWh. State-specific rates, local incentives, and charging availability — 10 largest EV states below.
The short version
EVs beat gas on fuel cost in every one of these states. The gap ranges from ~$500/yr (Hawaii) to over $1,200/yr (Washington). States with cheap hydro power plus expensive gas are where the math tilts furthest in EVs' favor.

What moves the needle between states
Electricity rate is the dominant variable
Washington's 10¢/kWh cuts 12,000 EV miles to $411/year. California's 31¢/kWh pushes the same miles to $1,234/year. That $823 difference dwarfs any variation in gas prices.
State incentives change the break-even math
California's $7,500 CVRP rebate and Colorado's $5,000 state credit offset much of the EV price premium. Texas offers $2,500. Without incentives, the payback takes longer.
