Check your vehicle's window sticker or owner's app — usually labeled "kWh/100mi" or convert from "miles/kWh."
Truck efficiency varies more than sedans — actual cost may differ from this estimate depending on driving style, speed, towing, and climate. We use long-term ownership averages where available rather than single best-case test results.
Estimates only. Actual costs vary by rate plan, driving conditions, and vehicle configuration.

Methodology: Utility rates reflect approximate blended residential averages as of mid-2026 (PG&E ~$0.39/kWh, SCE ~$0.345/kWh, SDG&E ~$0.457/kWh, SMUD ~$0.18/kWh blended off-peak/peak) sourced from utility rate schedules and CPUC filings. Public charging estimated at $0.50/kWh, reflecting the blended CA range for Level 2 public and DC fast charging ($0.40–0.60/kWh). Gas comparison uses a CA average price of $5.50/gallon and a 27 MPG blended baseline vehicle. Home solar marginal cost is estimated at $0.03/kWh, not $0 — this reflects real marginal cost rather than an inflated savings claim. Actual costs vary by rate plan, time-of-use scheduling, driving conditions, and vehicle configuration.
