Tesla Trip Cost Calculator
Planning a road trip in your Tesla? Wondering how much your next drive will cost in electricity? Our Tesla Trip Cost Calculator makes it easy to estimate your total trip cost, energy required (kWh), and cost per mile in just a few seconds.
Electric vehicles are known for lower operating costs compared to gasoline cars, but understanding exactly how much you’ll spend on a trip depends on three key factors:
- Trip distance
- Vehicle efficiency (kWh per 100 miles)
- Electricity rate per kWh
This calculator simplifies the math so you can plan smarter and travel confidently.
Why Calculate Tesla Trip Cost?
Driving a Tesla is efficient, but costs can vary depending on:
- Local electricity prices
- Driving style
- Weather conditions
- Terrain
- Vehicle model
Whether you're commuting daily or planning a long road trip, knowing your estimated cost helps you:
✅ Budget accurately
✅ Compare EV vs gas expenses
✅ Plan charging stops
✅ Understand cost per mile
✅ Optimize driving efficiency
How the Tesla Trip Cost Calculator Works
The calculator uses a simple and accurate formula:
Step 1: Calculate Energy Required
Energy Required (kWh) =
(Distance ÷ 100) × Efficiency
Efficiency is measured in kWh per 100 miles.
Step 2: Calculate Trip Cost
Trip Cost =
Energy Required × Electricity Rate
Step 3: Calculate Cost Per Mile
Cost per Mile =
Trip Cost ÷ Distance
The result gives you three clear outputs:
- Total energy required (kWh)
- Total trip cost ($)
- Cost per mile ($)
How to Use the Tesla Trip Cost Calculator
Using the tool is very simple:
1. Enter Trip Distance (Miles)
Input the total number of miles you plan to travel.
Example: 150 miles
2. Enter Vehicle Efficiency (kWh/100mi)
This represents how much energy your Tesla consumes per 100 miles.
Typical values:
- 23–28 kWh/100mi for efficient driving
- 30+ kWh/100mi for highway or aggressive driving
Default value in the calculator is 25 kWh/100mi.
3. Enter Electricity Rate (Per kWh)
Enter your electricity cost per kilowatt-hour.
Examples:
- $0.10 (low residential rate)
- $0.13 (U.S. average residential rate)
- $0.25+ (public fast charging)
4. Click “Calculate”
The calculator will instantly display:
- Energy Required (kWh)
- Trip Cost ($)
- Cost Per Mile ($)

Example Calculation
Let’s say:
- Distance: 200 miles
- Efficiency: 25 kWh/100mi
- Electricity Rate: $0.13 per kWh
Step 1: Energy Required
(200 ÷ 100) × 25 = 50 kWh
Step 2: Trip Cost
50 × 0.13 = $6.50
Step 3: Cost Per Mile
6.50 ÷ 200 = $0.0325 per mile
That means you’re driving for just over 3 cents per mile — significantly cheaper than most gasoline vehicles.
Comparing Tesla Cost vs Gasoline Cars
Let’s compare:
Gas car example:
- 30 MPG
- Gas price: $3.50/gallon
Cost per mile = 3.50 ÷ 30 = $0.116 per mile
Tesla example:
- 25 kWh/100mi
- $0.13 per kWh
Cost per mile ≈ $0.0325 per mile
That’s nearly 70% cheaper per mile in this scenario.
What Affects Tesla Efficiency?
Your actual efficiency may vary depending on:
- Driving speed
- Weather (cold reduces range)
- Use of heating or air conditioning
- Elevation changes
- Tire pressure
- Vehicle load
If you want more accurate estimates, adjust the efficiency number based on your real-world data from your Tesla dashboard.
Residential Charging vs Supercharging
Electricity cost varies depending on where you charge:
Home Charging
- Usually cheaper
- Lower electricity rates
- Ideal for daily commuting
Public Fast Charging
- More expensive
- Convenient for road trips
- Rates vary by location
For accurate results, enter the correct electricity rate for your charging source.
Why Cost Per Mile Matters
Cost per mile helps you:
- Compare EV models
- Track savings over time
- Calculate monthly commuting cost
- Evaluate trip budgets
For example:
If your commute is 40 miles daily and cost per mile is $0.03:
40 × 0.03 = $1.20 per day
About $36 per month (30 days)
Who Should Use This Calculator?
This Tesla Trip Cost Calculator is ideal for:
- Tesla owners
- EV buyers comparing costs
- Road trip planners
- Budget-conscious drivers
