Hawaii home charging cost for the 2026 Rivian R1S All-Terrain Performance Dual Max (20in)

A 2026 Rivian R1S All-Terrain Performance Dual Max (20in) draws 43.2 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $19.86 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: 24% 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

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Rivian R1S All-Terrain Performance Dual Max (20in) costs roughly $2,979 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $576 MORE a year than the gas comparison, not less.

Cost of a full charge

Covering the 2026 Rivian R1S All-Terrain Performance Dual Max (20in)'s EPA-rated 370-mile range takes about 159.9 kWh, which costs about $73.49 at Hawaii'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 20,324 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S All-Terrain Performance Dual Max (20in) alone ranks 334 of 400 models for efficiency; Hawaii alone ranks 51 of 51 states for electricity price.

Getting set up to charge a 2026 Rivian R1S All-Terrain Performance Dual Max (20in) at home

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.
