Missouri home charging cost for the 2026 Tesla Model S

In Missouri, home electricity runs 13.45¢/kWh — put a 2026 Tesla Model S's EPA-rated 27.1 kWh/100mi against that and 100 miles costs $3.65, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 77.2% 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 Tesla Model S costs roughly $547 a year to charge at home in Missouri, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,856 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.

Ask a licensed Missouri 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 13.45¢/kWh, Missouri sits in the middle of the national range — the guide to why charging cost varies by state shows where.
