What charging a Tesla actually costs
The math is simple: energy added × price per kWh, plus about 10% losses when AC charging at home. Energy added is battery size × the percentage gap you're filling.
Example — Model Y Long Range (75 kWh), 20% → 80% at home, $0.15/kWh:
- Energy into the pack: 75 × 0.60 = 45 kWh
- Energy from the wall: 45 × 1.1 ≈ 49.5 kWh
- Cost: 49.5 × $0.15 ≈ $7.43 — for about 200 miles of range
That's under 4¢ per mile. A 30 MPG gas car at $3.50/gallon costs ~12¢ per mile — three times as much. Supercharging at $0.25–$0.50/kWh lands between the two, which is why home charging is where EV savings really come from. If you're on a flat rate, check whether your utility offers a cheaper overnight EV tariff — our plan comparison tool shows what the switch would save.
Tesla charging cost FAQ
How much does it cost to charge a Tesla at home?
Battery × rate + ~10% losses. A 75 kWh pack from near-empty at $0.15/kWh is about $12.40; per-mile it works out around 4–5¢.
How much does Supercharging cost?
Typically $0.25–$0.50 per kWh depending on site and time — a 20–80% session on a 75 kWh pack runs $11–$22.
Is charging a Tesla cheaper than gas?
At home, usually about a third of the per-mile fuel cost of a 30 MPG car. Frequent Supercharging narrows the gap.
Why does my meter show more kWh than the battery gained?
AC charging loses ~10% to the onboard charger and cabling — 60 kWh into the pack draws about 66 kWh from the wall. The calculator includes this for home charging.
