Kentucky home charging cost for the 2026 Lexus RZ 450e AWD (20 inch wheels - 235/50R20)

In Kentucky, home electricity runs 14.37¢/kWh — put a 2026 Lexus RZ 450e AWD (20 inch wheels - 235/50R20)'s EPA-rated 31.2 kWh/100mi against that and 100 miles costs $4.48, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 72% less than gas per mile, here specifically.

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