Yearly home-charging cost
Based on the Ford Mustang Mach-E’s efficiency (3.3 mi/kWh) at Washington's average residential rate. For comparison, a 30-mpg gas car at $3.50/gallon runs about 12¢/mile.
Home vs. public fast charging
Costs below are for a 10%–80% charge — the usable fast-charge window, about 62 kWh of the Ford Mustang Mach-E’s 88 kWh battery. That’s the range most owners actually use, since charging past 80% slows down sharply.

Charging the Ford Mustang Mach-E on public DC fast chargers costs roughly 5.0× more than at home — about $24.64 extra per 10→80% charge. Most owners charge at home and only use fast charging on road trips, so your real average lands much closer to the home number.
Level 1 vs. Level 2: can your outlet keep up?
The cost per kWh is the same either way. What changes is how fast the Ford Mustang Mach-E recovers range while parked at home.
Level 1 · standard outlet
~4 mi/hour
120V · no installation needed
~10 hours to recover 40 miles of driving. A 10-hour overnight plug-in adds about 40 miles.
Level 2 · 240V circuit
~32 mi/hour
240V · uses the Ford Mustang Mach-E’s 9.6 kW onboard charger
~1 hour to recover 40 miles. A 10-hour overnight plug-in adds up to 317 miles.
If your daily driving stays under ~40 miles, a regular outlet may be all the Ford Mustang Mach-E needs. Drive more than that, and Level 2 — or a workplace charger — becomes the difference between an EV that fits your life and one that doesn’t.
Does a Level 2 install pay for itself?
A home Level 2 setup — 240V circuit plus charger — typically runs $800–$1,800 installed. If the alternative is relying on public fast chargers, home charging the Ford Mustang Mach-E in Washington saves about $121.21/month at 12,000 miles a year.
At a mid-range install cost of $1,300, that’s a payback of roughly 11 months — and every month after that is pure savings.
Winter in Washington
Washington averages about 3 months a year cold enough to cut EV efficiency — typically 15–25% in deep winter. Here’s what that does to the Ford Mustang Mach-E’s numbers at a 20% efficiency loss:
Cost per mile
~3.8¢vs. 3.0¢ in mild weather
Full-charge range
~232 mivs. ~290 mi
The cost bump is minor — a few dollars a month. The range cut matters more: if your daily driving is close to the Ford Mustang Mach-E’s limits, winter is when a marginal charging setup stops working.
Will a Ford Mustang Mach-E actually work for your home in Washington?
Cost is one piece. The bigger question is whether your outlet and daily driving keep you covered without relying on public chargers. Answer 5 quick questions for a clear, personalized answer.
