How to Use This Tesla Charging Cost Calculator?

1. Select Your Tesla Model

Choose your Tesla model from the dropdown list. Each option includes the typical battery capacity in kilowatt-hours (kWh), which determines how much energy your car can store and how much is needed to recharge it.

Model 3 Standard Range: ~50 kWh
Model 3/Y Long Range: ~75 kWh
Model 3/Y Performance: ~82 kWh
Model S/X Long Range: ~100 kWh

If you’re unsure, check your Tesla app or the owner’s manual.

2. Enter Current Battery Level

Input your current charge level in percent. For example, if your car is currently at 20%, enter 20. This helps the calculator estimate how much energy is already stored.

3. Enter Target Battery Level

Specify the charge level you want to reach. Many Tesla owners charge to 80–90% for daily use and reserve 100% charging for long trips. Enter a value higher than the current level.

4. Input Electricity Cost

Enter your cost per kWh — this varies by location and provider. Home electricity rates in the U.S. typically range from $0.10 to $0.30 per kWh, while public charging (e.g., Tesla Supercharger) can cost $0.25–$0.50 per kWh or more.

5. Click “Calculate”

After clicking the button, the calculator displays:

The amount of energy (kWh) needed to reach your target
The estimated cost for that charge session

You can easily try different values to simulate various scenarios.

Frequently Asked Questions (FAQ)

How much does it cost to charge a Tesla at home?

It depends on your electricity rate. For example:

Charging 60 kWh at $0.15/kWh = $9.00
Charging 60 kWh at $0.30/kWh = $18.00
This calculator gives a tailored estimate based on your charge level and energy prices.

Does this tool work for Superchargers?

Yes! Just enter the rate charged by the Supercharger in your area. Many Tesla Superchargers charge between $0.28 and $0.45 per kWh, depending on region and time of day.

What if I don’t charge to 100%?

That’s expected — many Tesla drivers regularly charge to 80–90% to maintain battery health. Just enter your desired charge level, and the tool will calculate based on that range.

Does this include charging losses?

No, this version calculates based on ideal energy transfer. Real-world charging is typically 90–95% efficient, meaning you might use 5–10% more electricity than calculated. You can adjust for this by increasing your cost per kWh slightly if you want a more realistic number.
