2027 Rivian R1S Performance (20in): home charging cost in Ohio

In Ohio, home electricity runs 18.53¢/kWh — put a 2027 Rivian R1S Performance (20in)'s EPA-rated 47 kWh/100mi against that and 100 miles costs $8.71, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 45.6% 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 2027 Rivian R1S Performance (20in) charged at home in Ohio costs about $1,306/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,097 a year.

Cost of a full charge

A 2027 Rivian R1S Performance (20in) needs roughly 163.5 kWh to reach its EPA-rated 348-mile range, which runs about $30.3 at 18.53¢/kWh in Ohio.

Where this ranks

This combination ranks 16,056 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rivian R1S Performance (20in) alone ranks 369 of 400 models for efficiency; Ohio alone ranks 34 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.
