2026 Rivian R1T Tri Max (22in): home charging cost in Arizona

At Arizona's residential electricity rate of 15.45¢/kWh, a 2026 Rivian R1T Tri Max (22in) (rated 44.6 kWh per 100 miles by the EPA) costs $6.89 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home is much cheaper than gas here: 57% less than gas per mile, here specifically.

2026 Rivian R1T Tri Max (22in): yearly cost in Arizona

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Rivian R1T Tri Max (22in) charged at home in Arizona costs about $1,033/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,370 a year.

What one full charge costs

A 2026 Rivian R1T Tri Max (22in) needs roughly 165.4 kWh to reach its EPA-rated 371-mile range, which runs about $25.55 at 15.45¢/kWh in Arizona.

How this compares nationally

This combination ranks 12,757 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1T Tri Max (22in) alone ranks 357 of 400 models for efficiency; Arizona alone ranks 25 of 51 states for electricity price.

Next step: home charger installation

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 Arizona electrician to quote the install before this math becomes a real decision.
