Oklahoma home charging cost for the 2026 Rivian R1T All-Terrain Dual Large (20in)

In Oklahoma, home electricity runs 13.37¢/kWh — put a 2026 Rivian R1T All-Terrain Dual Large (20in)'s EPA-rated 44.4 kWh/100mi against that and 100 miles costs $5.93, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 63% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Rivian R1T All-Terrain Dual Large (20in) costs roughly $890 a year to charge at home in Oklahoma, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,513 a year.

Cost of a full charge

Covering the 2026 Rivian R1T All-Terrain Dual Large (20in)'s EPA-rated 289-mile range takes about 128.2 kWh, which costs about $17.14 at Oklahoma's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

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.
