How to use this calculator
- Enter a realistic baseline range.
- Estimate separate temperature, payload, and auxiliary penalties.
- Enter planned route miles.
- Review adjusted range and route buffer.

Electric Truck Range Loss Calculator
Estimate how cold or hot weather, payload, auxiliary loads, and operating conditions may reduce the usable range of an electric truck. Compare adjusted range with a planned route and identify the remaining distance buffer.
Calculator
Fleet scenario inputsFormula
Adjusted range = baseline range × (1 − combined loss). Combined loss = 1 − (1 − temperature loss) × (1 − payload loss) × (1 − auxiliary loss).
What the result means
The adjusted range is a scenario estimate. Multiplying retained factors prevents separate percentage losses from being simply added beyond a sensible scale.
Road grade, speed, wind, tire pressure, traffic, and battery age can also change real-world range.
Example calculation
For 300 miles of baseline range with 15% temperature, 8% payload, and 6% auxiliary losses, adjusted range is 221 miles.
Tips for better results
- Use telematics data from comparable routes.
- Keep a dispatch reserve rather than planning to zero charge.
- Separate seasonal scenarios.
- Reduce avoidable auxiliary loads while preserving safety and comfort.
Frequently asked questions
Why are the range-loss percentages multiplied instead of added?
Each penalty applies to the range remaining after the previous factor, which avoids overstating the combined loss.
Should I enter EPA range or observed fleet range?
Observed range from similar routes is usually more useful; rated range can be used as a starting point.
Does payload always reduce range by the same percentage?
No. The effect varies with vehicle mass, speed, grade, and stop frequency, so use measured fleet data when available.
What does a negative route buffer mean?
It means the planned route is longer than the estimated adjusted range for the entered scenario.
Does the estimate include battery degradation?
Only if your baseline range already reflects it; otherwise include degradation as part of a conservative baseline or another loss input.
