South Carolina home charging cost for the 2026 Mercedes-Benz EQS 450 4matic

At South Carolina's residential electricity rate of 16.04¢/kWh, a 2026 Mercedes-Benz EQS 450 4matic (rated 37 kWh per 100 miles by the EPA) costs $5.93 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home is much cheaper than gas here: 63% 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 2026 Mercedes-Benz EQS 450 4matic costs roughly $890 a year to charge at home in South Carolina, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,513 a year.

Cost of a full charge

Covering the 2026 Mercedes-Benz EQS 450 4matic's EPA-rated 367-mile range takes about 135.8 kWh, which costs about $21.78 at South Carolina's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

This combination ranks 9,090 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Mercedes-Benz EQS 450 4matic alone ranks 196 of 400 models for efficiency; South Carolina alone ranks 27 of 51 states for electricity price.

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 South Carolina electrician to quote the install before this math becomes a real decision.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. At 16.04¢/kWh, South Carolina sits in the middle of the national range — the guide to why charging cost varies by state shows where.
