California home charging cost for the 2026 Rivian R1T Quad Max (20in AT)

In California, home electricity runs 33.17¢/kWh — put a 2026 Rivian R1T Quad Max (20in AT)'s EPA-rated 50.1 kWh/100mi against that and 100 miles costs $16.62, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 3.7% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Rivian R1T Quad Max (20in AT) costs roughly $2,493 a year to charge at home in California, against roughly $2,403 a year for an equivalent gas car. That's about $90 MORE a year than the gas comparison, not less.

Filling up the 2026 Rivian R1T Quad Max (20in AT), in dollars

Covering the 2026 Rivian R1T Quad Max (20in AT)'s EPA-rated 325-mile range takes about 162.8 kWh, which costs about $54.01 at California's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

This combination ranks 20,145 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1T Quad Max (20in AT) alone ranks 393 of 400 models for efficiency; California alone ranks 50 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.

Where these figures come from

The methodology guide names the exact EIA and EPA tables behind this page's numbers. 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.
