2026 Rivian R1T All-Terrain Tri Max (20in), CA Charging Cost

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.
