Massachusetts home charging cost for the 2026 Rivian R1T Quad Max (22in)
In Massachusetts, home electricity runs 30.06¢/kWh — put a 2026 Rivian R1T Quad Max (22in)'s EPA-rated 44.4 kWh/100mi against that and 100 miles costs $13.34, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is cheaper than gas here: 16.7% 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.
