Delaware home charging cost for the 2026 Ford Mustang Mach-E RWD Extended
A 2026 Ford Mustang Mach-E RWD Extended draws 30.7 kWh per 100 miles per the EPA; at Delaware's 17.74¢/kWh residential rate that's $5.44 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a fraction of what gas would here: 66% less than gas per mile, here specifically.
Annual cost, at 15 thousands miles a year
At fueleconomy.gov's default of 15,000 annual miles, the 2026 Ford Mustang Mach-E RWD Extended costs roughly $816 a year to charge at home in Delaware, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,587 a year.
What one full charge costs
Covering the 2026 Ford Mustang Mach-E RWD Extended's EPA-rated 320-mile range takes about 98.1 kWh, which costs about $17.41 at Delaware's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.
How this compares nationally

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.
