Delaware home charging cost for the 2026 Tesla Model Y Standard RWD (18in Wheels)
At Delaware's residential electricity rate of 17.74¢/kWh, a 2026 Tesla Model Y Standard RWD (18in Wheels) (rated 24.3 kWh per 100 miles by the EPA) costs $4.32 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.

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