Hawaii home charging cost for the 2027 Rivian R1T Quad (20in AT)

A 2027 Rivian R1T Quad (20in AT) draws 50.1 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $23.02 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: 43.7% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

Cost of a full charge

Covering the 2027 Rivian R1T Quad (20in AT)'s EPA-rated 325-mile range takes about 162.8 kWh, which costs about $74.82 at Hawaii's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

How this compares nationally

This combination ranks 20,390 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1T Quad (20in AT) alone ranks 391 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.

Ask a licensed Hawaii electrician to quote the install before this math becomes a real decision.

Where these figures come from

See the methodology guide for exactly which EIA and EPA figures feed 2027 Rivian R1T Quad (20in AT)'s cost in Hawaii. 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.
