What is EV Range?
EV range is how far you can drive on available battery charge under real conditions. Rated EPA range assumes a test cycle; actual range drops with cold weather (20–40%), highway speed (aerodynamic drag), heater or AC use, and payload. Range = (Battery kWh × Usable %) ÷ Consumption (kWh/mile).
Use this page for trip planning and range anxiety checks — model your efficiency, current charge level, outdoor temperature, and climate settings to see adjusted miles remaining. Regenerative braking helps in city driving; highway cruising consumes more per mile than EPA suggests.
To calculate how much a charge costs in dollars and how long it takes at home or a DC fast station, use the EV Charging Cost Calculator. That page focuses on $/kWh economics; this page focuses on miles you can actually drive.
How the EV Range Calculator Works
Formula, assumptions, and calculation steps for this automotive tool.
Formula Used
Range (miles) = Battery Capacity (kWh) / Efficiency (kWh per mile)
Methodology
Divides usable battery capacity by the vehicle's energy efficiency to estimate real-world driving range.
Calculation Steps
- Enter distance, fuel use, price, payment, or vehicle value assumptions.
- Normalize miles/kilometers, gallons/liters, and monthly periods.
- Apply the relevant cost, efficiency, or depreciation formula.
- Show per-trip, monthly, or ownership totals.
Assumptions and Limits
- Fuel prices, insurance, taxes, and resale values change over time.
- Driving style and maintenance history affect real costs.
- Use results for planning and comparison.
Frequently Asked Questions
Cold temperatures affect EV range in two main ways: battery chemistry slows down (reducing available capacity), and heating the cabin consumes significant energy since EVs cannot use engine waste heat like gas cars. At -10°F, some EVs can lose 40–50% of their rated range. Modern EVs with heat pump systems suffer less than those using resistive heating. Pre-conditioning the battery and cabin while plugged in helps significantly.
Yes — this is opposite to gas cars. EVs are most efficient in stop-and-go city driving because regenerative braking recovers energy. At highway speeds (70–80 mph), aerodynamic drag increases exponentially, significantly reducing efficiency. A Tesla Model 3 rated at 358 miles might get 400+ miles in city driving but only 280–300 miles on the highway at 75 mph.
Regenerative braking converts the kinetic energy of slowing down back into electricity, which is stored in the battery. In city driving with frequent stops, regen can recover 15–25% of energy that would otherwise be lost as heat in brake pads. EVs with one-pedal driving (strong regen when lifting off the accelerator) maximize this benefit. Highway driving has fewer opportunities for regen.
Manufacturer EPA range estimates are based on standardized tests. Real-world range typically comes in 10–20% below EPA estimates for mixed driving. At highway speeds in cold weather with the heater on, you might see 30–40% below EPA. This calculator provides a realistic adjusted estimate. For trip planning, always factor in a 20–30% buffer and know the locations of charging stations.
