Yearly home-charging cost
Based on the Toyota bZ’s efficiency (3.4 mi/kWh) at California'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 52 kWh of the Toyota bZ’s 74.7 kWh battery. That’s the range most owners actually use, since charging past 80% slows down sharply.

Charging the Toyota bZ on public DC fast chargers costs roughly 1.8× more than at home — about $11.45 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 Toyota bZ 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 41 miles.
Level 2 · 240V circuit
~33 mi/hour
240V · uses the Toyota bZ’s 9.6 kW onboard charger
~1 hour to recover 40 miles. A 10-hour overnight plug-in adds up to 326 miles.
If your daily driving stays under ~41 miles, a regular outlet may be all the Toyota bZ 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 Toyota bZ in California saves about $64.41/month at 12,000 miles a year.
At a mid-range install cost of $1,300, that’s a payback of roughly 1.7 years — and every month after that is pure savings.
Will a Toyota bZ actually work for your home in California?
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.
