2027 Rivian R1T Performance (20in AT): home charging cost in California

In California, home electricity runs 33.17¢/kWh — put a 2027 Rivian R1T Performance (20in AT)'s EPA-rated 49.8 kWh/100mi against that and 100 miles costs $16.53, versus $16.02 for a gas car averaging 25.5 mpg. 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.

2027 Rivian R1T Performance (20in AT): yearly cost in California

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2027 Rivian R1T Performance (20in AT) 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.

What one full charge costs

A 2027 Rivian R1T Performance (20in AT) needs roughly 164 kWh to reach its EPA-rated 329-mile range, which runs about $54.38 at 33.17¢/kWh in California.

Where this ranks

This combination ranks 20,135 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1T Performance (20in AT) alone ranks 387 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.
