2026 Rivian R1T Performance Dual Large (22in): home charging cost in Hawaii

In Hawaii, home electricity runs 45.95¢/kWh, put a 2026 Rivian R1T Performance Dual Large (22in)'s EPA-rated 39.5 kWh/100mi against that and 100 miles costs $18.14, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 13.2% 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 Performance Dual Large (22in) charged at home in Hawaii costs about $2,721/year in electricity, against about $2,403/year for the gas-car comparison. That's about $318 MORE a year than the gas comparison, not less.

Cost of a full charge

A 2026 Rivian R1T Performance Dual Large (22in) needs roughly 129.9 kWh to reach its EPA-rated 329-mile range, which runs about $59.67 at 45.95¢/kWh in Hawaii.

Getting set up to charge a 2026 Rivian R1T Performance Dual Large (22in) 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.

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.
