Idaho home charging cost for the 2027 Mercedes-Benz EQS 550 4matic (SUV)
In Idaho, home electricity runs 12.8¢/kWh — put a 2027 Mercedes-Benz EQS 550 4matic (SUV)'s EPA-rated 42 kWh/100mi against that and 100 miles costs $5.38, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 66.4% less than gas per mile, here specifically.
Annual cost, at 15 thousands miles a year
At fueleconomy.gov's default of 15,000 annual miles, the 2027 Mercedes-Benz EQS 550 4matic (SUV) costs roughly $806 a year to charge at home in Idaho, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,597 a year.
Cost of a full charge
Covering the 2027 Mercedes-Benz EQS 550 4matic (SUV)'s EPA-rated 317-mile range takes about 133.1 kWh, which costs about $17.04 at Idaho's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.
How this compares nationally
This combination ranks 6,378 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Mercedes-Benz EQS 550 4matic (SUV) alone ranks 303 of 400 models for efficiency; Idaho alone ranks 3 of 51 states for electricity price.
Before you install a home charger in Idaho
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.

Where these figures come from
Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. Idaho is one of the cheapest states for home electricity — the guide to why the cost varies so much by state covers what drives that.
