Find out exactly what your Tesla road trip will cost — in charging dollars, not guesses. Add multiple legs, choose your model, split between Supercharger and home charging, adjust for season and speed, compare against a gas car, rental, or flight, and see your cost per person and CO₂ saved. No other Tesla trip calculator does all of this.
See how your Tesla trip cost stacks up against driving a gas car, renting a car, or flying. Uses total distance from your trip legs above.
Common questions about Tesla road trip costs, Supercharger pricing, efficiency, and how this calculator works.
It depends on your model, charging source, and trip distance. A rough rule of thumb: Tesla Model Y LR uses about 0.285 kWh per mile at highway speeds. At the average Supercharger rate of ~22¢/kWh (2026), that's about 6.3¢ per mile. A 500-mile road trip would cost roughly $31–$40 at Superchargers, or about $20 if you can charge overnight at home. Compare that to a gas car at 28 MPG and $3.65/gallon — which costs about $65 for the same trip. This calculator handles all those numbers for you automatically.
Tesla Supercharger pricing in the US averages 22–25¢ per kWh in 2026, billed per kWh in most states (a few states bill per minute due to state regulations). Tesla+ members can access lower rates. Peak-hour pricing adds 25–50% at busy locations. Some states with very low grid electricity costs (parts of Texas, Midwest) see rates as low as 18¢/kWh. Hawaii and California average closer to 27¢/kWh. This calculator lets you select your expected Supercharger rate and blend it with home charging to get an accurate total cost.
This calculator estimates charging stops based on your model's usable range, starting at 80% charge (Tesla recommends not departing below 80% for highway trips) and charging to 80% at each stop (above 80%, charging slows significantly). As a reference: Model Y LR has ~310 miles of EPA range, but at 70 mph highway speed you get about 270–285 practical miles per charge. For a 600-mile trip that's approximately 2 stops of about 25–30 minutes each. Winter cold or driving at 80+ mph can require an extra stop.
Yes — significantly. Cold weather reduces Tesla's real-world range by 15–30% depending on temperature. At 20°F, a Model Y LR might get only 215 miles per charge instead of 310. This means more charging stops and higher total cost. This calculator includes a season adjustment: selecting "Cold Winter" automatically applies a 25% efficiency penalty, and "Very Cold (<20°F)" applies 30%. If you're planning a winter road trip through the Northeast or Midwest, always add at least one extra charging stop buffer beyond what the calculator estimates.
Speed is the single biggest variable in Tesla efficiency after temperature. Above 65 mph, aerodynamic drag grows exponentially — driving at 80 mph uses about 20–25% more energy per mile than 65 mph. This calculator applies a speed penalty: selecting "75–80 mph" reduces effective efficiency by 10%, and "85+ mph" reduces it by 18%. On a long highway trip, slowing from 80 mph to 70 mph can reduce your charging cost by $15–25 and eliminate one stop entirely.
Almost always yes — often by 40–70% in fuel cost savings. A Tesla Model Y at Supercharger rates costs about 6–7¢/mile vs. a 28 MPG gas car at $3.65/gallon costing about 13¢/mile. Over a 1,000-mile round trip, you'd spend roughly $65–80 (Tesla) vs. $130–150 (gas car). The gap widens if you charge primarily at home (where electricity is cheaper), and narrows if you're exclusively Supercharging. Use the comparison tab to see the exact numbers for your trip. See also our Tesla vs human cost analysis for a broader economic perspective.
The cheapest option, by far, is charging at home the night before and again at your destination (if you're staying somewhere with a plug). Home electricity costs 12–18¢/kWh vs. 22–27¢/kWh at Superchargers — that's 30–50% cheaper per kWh. For multi-day trips, staying at hotels with EV charging (Level 2) or campgrounds with 50-amp hookups can dramatically reduce Supercharger dependence. Many Marriott, Hilton, and Hyatt properties now offer free Level 2 charging. This calculator lets you set the percentage of charging done at home vs. Superchargers so you can model any scenario.
The presets use real-world highway efficiency data from TeslaFi fleet averages and owner community data (not EPA rated range, which is measured differently). At highway speeds with climate control: Model Y LR ~3.5 mi/kWh, Model 3 LR ~4.0 mi/kWh, Model X ~2.9 mi/kWh. You can override these with your own car's actual average from the Tesla app's trip history. Your lifetime efficiency in the app is the most accurate input you can use — enter it in the "Custom Efficiency" field.
Simply select the number of passengers in the calculator above — the cost per person is displayed automatically. A Tesla road trip for 4 people costs roughly the same in electricity as a 1-person trip, so the per-person cost drops dramatically with more passengers. At 4 passengers, a $60 charging trip costs only $15 per person — often cheaper per capita than a $120 gas bill split 4 ways for the same trip.
The calculator estimates CO₂ savings using the US average grid emissions factor of 0.386 kg CO₂ per kWh and compares it to a gas car's tailpipe emissions (2.31 kg CO₂ per liter of gasoline, or ~10.7 kg per gallon). On a 500-mile road trip, a Model Y LR produces roughly 56 lbs of CO₂-equivalent (from electricity generation) vs. about 163 lbs for a 28 MPG gas car — a saving of over 100 lbs per trip. In states with cleaner grids (CA, WA, NY), Tesla's CO₂ footprint is significantly lower.
Yes — that's one of the main things that sets this calculator apart. Click "Add Another Leg" to add up to 5 trip segments, each with its own distance. This lets you plan trips like NY → Philadelphia → Washington DC → Charlotte without having to manually add up the legs. Each leg shows its estimated charging cost individually, and the results panel shows the full trip total.
