Montana home charging cost for the 2027 Audi A6 e-tron quattro

In Montana, home electricity runs 13.77¢/kWh — put a 2027 Audi A6 e-tron quattro's EPA-rated 32 kWh/100mi against that and 100 miles costs $4.4, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 72.5% 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.

Ask a licensed Montana electrician to quote the install before this math becomes a real decision.

Where these figures come from
