2026 Rivian R1S Dual Max (22in): home charging cost in Kentucky

A 2026 Rivian R1S Dual Max (22in) draws 39.9 kWh per 100 miles per the EPA; at Kentucky's 14.37¢/kWh residential rate that's $5.74 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home is much cheaper than gas here: 64.2% 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 (22in) charged at home in Kentucky costs about $861/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,542 a year.

Cost of a full charge

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.
