2027 Rivian R1S Premium (22in), OK Charging Cost

Oklahoma home charging cost for the 2027 Rivian R1S Premium (22in)

In Oklahoma, home electricity runs 13.37¢/kWh, put a 2027 Rivian R1S Premium (22in)'s EPA-rated 39.5 kWh/100mi against that and 100 miles costs $5.28, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 67.1% less than gas per mile, here specifically.

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

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset, see the methodology guide. Oklahoma is one of the cheapest states for home electricity, the guide to why the cost varies so much by state covers what drives that.
