2026 Tesla Model Y Standard RWD (18in Wheels): home charging cost in Colorado

At Colorado's residential electricity rate of 16.65¢/kWh, a 2026 Tesla Model Y Standard RWD (18in Wheels) (rated 24.3 kWh per 100 miles by the EPA) costs $4.05 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 costs a fraction of what gas would here: 74.7% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Tesla Model Y Standard RWD (18in Wheels) charged at home in Colorado costs about $608/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,795 a year.

Cost of a full charge

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