2026 Ford Mustang Mach-E RWD: home charging cost in Illinois
In Illinois, home electricity runs 19.22¢/kWh — put a 2026 Ford Mustang Mach-E RWD's EPA-rated 31.4 kWh/100mi against that and 100 miles costs $6.04, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 62.3% less than gas per mile, here specifically.
Annual cost, at 15 thousands miles a year

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