Home vs. public fast charging
Costs below are for a 10%–80% charge — the usable fast-charge window, about 55 kWh of the Tesla Model Y’s 79 kWh battery. That’s the range most owners actually use, since charging past 80% slows down sharply.

Charging the Tesla Model Y on public DC fast chargers costs roughly 3.1× more than at home — about $18.80 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 Tesla Model Y recovers range while parked at home.
Level 1 · standard outlet
~5 mi/hour
120V · no installation needed
~9 hours to recover 40 miles of driving. A 10-hour overnight plug-in adds about 46 miles.
Level 2 · 240V circuit
~36 mi/hour
240V · uses the Tesla Model Y’s 9.6 kW onboard charger
~1 hour to recover 40 miles. A 10-hour overnight plug-in adds up to 365 miles.
If your daily driving stays under ~46 miles, a regular outlet may be all the Tesla Model Y 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 Tesla Model Y in Santa Fe saves about $89.47/month at 12,000 miles a year.
At a mid-range install cost of $1,300, that’s a payback of roughly 15 months — and every month after that is pure savings.
