2026 Rivian R1S Dual Max (20in): home charging cost in Utah

In Utah, home electricity runs 13.17¢/kWh — put a 2026 Rivian R1S Dual Max (20in)'s EPA-rated 42 kWh/100mi against that and 100 miles costs $5.53, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 65.5% less than gas per mile, here specifically.

What a year of driving costs

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Rivian R1S Dual Max (20in) charged at home in Utah costs about $829/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,574 a year.

Cost of a full charge

A 2026 Rivian R1S Dual Max (20in) needs roughly 159.5 kWh to reach its EPA-rated 380-mile range, which runs about $21.01 at 13.17¢/kWh in Utah.

How this compares nationally

This combination ranks 7,157 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Dual Max (20in) alone ranks 298 of 400 models for efficiency; Utah alone ranks 4 of 51 states for electricity price.

Before you install a home charger in Utah

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. Utah is one of the cheapest states for home electricity — the guide to why the cost varies so much by state covers what drives that.
