2026 Cadillac LYRIQ AWD: home charging cost in Montana

A 2026 Cadillac LYRIQ AWD draws 39.7 kWh per 100 miles per the EPA; at Montana's 13.77¢/kWh residential rate that's $5.47 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a fraction of what gas would here: 65.9% less than gas per mile, here specifically.

What a year of driving costs

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.
