2026 Rivian R1T All-Terrain Tri Max (20in): home charging cost in California

At California's residential electricity rate of 33.17¢/kWh, a 2026 Rivian R1T All-Terrain Tri Max (20in) (rated 49.8 kWh per 100 miles by the EPA) costs $16.53 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. This model costs more to charge at home than gas would here: 3.2% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

What a year of driving costs

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Rivian R1T All-Terrain Tri Max (20in) charged at home in California costs about $2,480/year in electricity, against about $2,403/year for the gas-car comparison. That's about $77 MORE a year than the gas comparison, not less.

Cost of a full charge

A 2026 Rivian R1T All-Terrain Tri Max (20in) needs roughly 164 kWh to reach its EPA-rated 329-mile range, which runs about $54.38 at 33.17¢/kWh in California.

How this compares nationally

This combination ranks 20,137 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1T All-Terrain Tri Max (20in) alone ranks 389 of 400 models for efficiency; California alone ranks 50 of 51 states for electricity price.

Before you install a home charger in California

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.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. This is one of the combinations where charging costs more than gas — the guide to when that happens explains why the arithmetic can go either way.
