Arizona home charging cost for the 2026 Tesla Model 3 Performance

In Arizona, home electricity runs 15.45¢/kWh — put a 2026 Tesla Model 3 Performance's EPA-rated 29.6 kWh/100mi against that and 100 miles costs $4.57, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 71.5% less than gas per mile, here specifically.

Cost of a full charge

Covering the 2026 Tesla Model 3 Performance's EPA-rated 309-mile range takes about 91.4 kWh, which costs about $14.12 at Arizona's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Before you install a home charger in Arizona

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

Where these figures come from
