2026 Mercedes-Benz EQS 450 Plus: home charging cost in Wisconsin

In Wisconsin, home electricity runs 18.99¢/kWh — put a 2026 Mercedes-Benz EQS 450 Plus's EPA-rated 34 kWh/100mi against that and 100 miles costs $6.46, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 59.7% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Mercedes-Benz EQS 450 Plus charged at home in Wisconsin costs about $969/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,434 a year.

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.
