2026 Rivian R1S Quad Max (22in): home charging cost in Nevada

At Nevada's residential electricity rate of 13.79¢/kWh, a 2026 Rivian R1S Quad Max (22in) (rated 44.4 kWh per 100 miles by the EPA) costs $6.12 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home is much cheaper than gas here: 61.8% less than gas per mile, here specifically.

What a year of driving costs

How this compares nationally

This combination ranks 9,974 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Quad Max (22in) alone ranks 350 of 400 models for efficiency; Nevada alone ranks 11 of 51 states for electricity price.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Ask a licensed Nevada electrician to quote the install before this math becomes a real decision.
