2026 Rivian R1T All-Terrain Dual Large Plus (20in): home charging cost in Hawaii

A 2026 Rivian R1T All-Terrain Dual Large Plus (20in) draws 46.9 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $21.54 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. This model costs more to charge at home than gas would here: 34.5% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Rivian R1T All-Terrain Dual Large Plus (20in) charged at home in Hawaii costs about $3,232/year in electricity, against about $2,403/year for the gas-car comparison. That's about $829 MORE a year than the gas comparison, not less.

What one full charge costs

A 2026 Rivian R1T All-Terrain Dual Large Plus (20in) needs roughly 136.9 kWh to reach its EPA-rated 292-mile range, which runs about $62.91 at 45.95¢/kWh in Hawaii.

How this compares nationally

This combination ranks 20,360 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1T All-Terrain Dual Large Plus (20in) alone ranks 367 of 400 models for efficiency; Hawaii alone ranks 51 of 51 states for electricity price.

Before you install a home charger in Hawaii

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.
