Electric Car Range & Full Charge Cost
Find out how far your electric car can go on a full charge and how much it costs to fully charge the battery. Estimate your driving range based on battery size and real-world conditions. See how electricity prices affect your total charging cost.
Full charge means charging the battery from 0% to 100%.
This calculator shows how far your electric car can go on a full battery and how much that full charge costs.
Real-world EV range depends on battery size, driving efficiency, and conditions like weather, terrain, and speed. Cold temperatures and highway speeds both lower range, while gentle city driving usually increases it.
What your result means
A 75 kWh pack in a Tesla Model 3 Long Range under "normal weather, mixed driving" conditions gives about 300 miles — roughly 4 miles per kWh, at $0.04 per mile with $0.15/kWh electricity.
What you actually get between a 10% floor and an 80% daily charge limit — plan trips on this number, not the full-charge figure.
At the US average of 37 miles a day. Most drivers plug in far less often than they expect.
A 30 mpg gas car at $3.10/gal costs $10.33 for the same 100 miles.
How to get more range out of this battery
- Drop 5–10 mph on the highwayabout 27 mi
Aerodynamic drag rises with the square of speed, so highway pace is the single biggest controllable factor. In this model the highway case is 273 miles against 300 in mixed driving.
- Precondition the cabin while still plugged inup to 60 mi in winter
Heating a cold cabin from the pack is what makes the sub-20°F case land at 240 miles. Warming the car on shore power moves that energy off the battery, and a heat pump recovers much of the rest.
- Plan on 10→80%, not 0→100%210 mi usable
Charging to 100% is slow and hard on most chemistries, and arriving at 0% is not an option. Treating 210 miles as your working range makes trip planning honest — and a comfortable there-and-back radius is about 120 miles.
- Check tyre pressure and remove roof accessories3–8%
Underinflated tyres and a roof box or bike rack each measurably raise consumption. Both act on the kWh-per-mile figure this calculator uses, so the range gain applies in every condition.
- Enter your own kWh/mile once you have dataAccuracy
This page models the Tesla Model 3 Long Range at 0.25 kWh per mile. Your car's lifetime efficiency readout is the better number — adjust the battery field proportionally if your real consumption differs.
Worked examples
Example A — winter commute in a Nissan Leaf
- Model
- Nissan Leaf (0.30 kWh/mi)
- Battery
- 40 kWh
- Conditions
- Cold below 20°F (1.25x)
- Electricity
- $0.15/kWh
40 ÷ (0.30 × 1.25) = 107 miles → 10→80% usable = 75 miles → full charge cost = 40 × 0.15 = $6.00 → 6.00 ÷ 107 = $0.056 per mile
A 40 kWh car still covers a 30-mile round-trip commute every day of winter with margin. The cold penalty matters for weekend trips, not for commuting.
Example B — Model S road trip at highway speed
- Model
- Tesla Model S (0.28 kWh/mi)
- Battery
- 100 kWh
- Conditions
- Highway (1.1x)
- Electricity
- $0.35/kWh (Supercharger)
100 ÷ (0.28 × 1.1) = 325 miles → 10→80% usable = 227 miles → full charge cost = 100 × 0.35 = $35.00 → 35.00 ÷ 325 = $0.108 per mile
Plan Supercharger stops every 200–230 miles, not every 325. At Supercharger pricing the per-mile cost is close to a 30 mpg gas car — the saving comes back as soon as you are home.
Real-world range vs EPA range
The EPA rating is a benchmark, not a guarantee. Owners typically see 85–95% of the rated range in mild weather and 65–80% in winter or at high speeds. Driving style matters as much as the badge on the car.
Highway vs city range
Unlike gas cars, EVs are more efficient in town. Highway speeds above 65 mph create exponentially more aerodynamic drag, eating into range. Slowing from 80 mph to 65 mph can add 30–50 miles of effective range to a long trip.
Weather impact on battery range
Cold temperatures reduce range two ways: chemistry slows in the battery, and cabin heating draws energy. A heat pump (now standard on most new EVs) softens the blow significantly compared to older resistive heaters.
Towing and passenger weight
Towing can cut EV range by 40–60% — a Cybertruck or F-150 Lightning pulling a camper at 65 mph might see only 100–150 miles per charge. Heavy passenger and cargo loads have a smaller effect: ~5–10% reduction.
Driving habits that change everything
Smooth acceleration, anticipating stops to use regen, drafting trucks at safe distances on highways, and turning off climate control when comfortable can each add 5–15 miles of usable range.
Quick facts
Range scenarios for a 75 kWh EV
| Scenario | Conditions | Estimated range |
|---|---|---|
| Ideal | 60 mph, 70°F, no heat/AC | ~290 mi |
| Daily mixed | City + highway, mild weather | ~250 mi |
| Highway 75 mph | AC on | ~210 mi |
| Cold winter day | 20°F, heat on | ~190 mi |
| Towing trailer | 65 mph, 3,000 lb | ~120 mi |
EV trip planning tips
- Charge to 100% only when you actually need the range — daily 80% is healthier.
- Use A Better Routeplanner to factor weather and elevation into stops.
- Pre-condition the cabin while plugged in to keep range out on the road.
- Slow down 5 mph on highways for noticeably better arrival range.
Most EV drivers use less than 20% of their battery on a typical day — meaning 'range anxiety' is usually about the rare trip, not daily driving.
