2026 Rivian R1S Quad Max (22in): home charging cost in North Carolina
A 2026 Rivian R1S Quad Max (22in) draws 44.4 kWh per 100 miles per the EPA; at North Carolina's 14.9¢/kWh residential rate that's $6.61 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: 58.7% 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.
