2026 Tesla Model 3 Standard RWD: home charging cost in Wisconsin

In Wisconsin, home electricity runs 18.99¢/kWh — put a 2026 Tesla Model 3 Standard RWD's EPA-rated 24.3 kWh/100mi against that and 100 miles costs $4.62, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 71.2% less than gas per mile, here specifically.

Before you install a home charger in Wisconsin

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