Enter your Tesla model, current battery level, target battery level, and electricity rate ($/kWh) to calculate exactly how much it will cost to charge your Tesla. You'll get the total charging cost, energy needed (kWh), and estimated cost per mile — plus a visual breakdown of your charging session.

The cost depends on your Tesla model's battery size and your local electricity rate. For example, charging a Model 3 Long Range (82 kWh) from 20% to 90% at the US average rate of $0.16/kWh costs roughly $9–$11. Home charging is typically the cheapest option, often 50–70% less than using a Supercharger.
Tesla Supercharger rates typically range from $0.25 to $0.50 per kWh depending on location and time of day. Charging a Model 3 Long Range from 20% to 90% at a Supercharger would cost approximately $14–$29. Some older Tesla vehicles and certain subscription plans may offer free or discounted Supercharging.
The formula is: Cost = Battery Capacity (kWh) × Charge % Added × Electricity Rate ÷ Charging Efficiency. For example, an 82 kWh battery charged from 20% to 90% (70% added) at $0.16/kWh with 90% efficiency = 82 × 0.70 × $0.16 ÷ 0.90 ≈ $10.22.
Charging efficiency refers to the percentage of electricity drawn from the grid that actually reaches your battery — the rest is lost as heat. AC home chargers are typically 85–92% efficient, while DC fast chargers like Superchargers can be 92–95% efficient. This means you always draw slightly more kWh from the grid than what ends up stored in the battery.
No, most Superchargers are not free. Tesla ended its free unlimited Supercharging promotion for new vehicle purchases in 2017. Some used vehicles purchased through Tesla or certain promotional deals may still have free Supercharging attached to the vehicle. Tesla's current pay-per-use Supercharger rates vary by region and station.
Approximate full-charge costs at $0.16/kWh: Model 3 RWD (57.5 kWh) ≈ $10.22, Model 3/Y Long Range (82 kWh) ≈ $14.58, Model S/X 100D (100 kWh) ≈ $17.78, Cybertruck (123 kWh) ≈ $21.87. These figures assume 90% charging efficiency and charging from 0% to 100%.
Estimate the total miles for your trip and divide by your Tesla's efficiency (miles per kWh) to get the energy needed. Then multiply by the electricity rate at the stations you'll use. For Superchargers, factor in the per-kWh rate at each stop. Our calculator helps you estimate individual charging session costs that you can add up for the full trip.
Yes, many utilities offer Time-of-Use (TOU) rates where overnight electricity (typically 9 PM–6 AM) can be 30–50% cheaper than peak rates. You can enter your off-peak rate into our calculator to see how much you'd save. Tesla vehicles support scheduled charging, so you can set them to charge automatically during cheaper overnight hours.
