Electric Truck Energy Cost Calculator
Estimate electricity cost per trip, per mile, and across a monthly electric truck schedule. The calculation accounts for vehicle energy use, charging losses, local electricity price, route distance, and operating days.
Calculator
Fleet scenario inputsFormula
Monthly battery energy = distance × energy per mile × days. Grid energy = battery energy ÷ charging efficiency. Monthly cost = grid energy × electricity price.
What the result means
The main result is estimated monthly electricity expense. It excludes demand charges, charger fees, maintenance, financing, and driver labor.
For time-of-use tariffs, calculate separate scenarios or use a weighted average energy rate.
Example calculation
At 1.75 kWh/mi, 100 miles per day, 22 days, 92% efficiency, and $0.16/kWh, monthly cost is $669.57.
Tips for better results
- Use an all-in rate from recent bills.
- Track energy consumption by route and season.
- Include charging losses rather than billing only battery energy.
- Model demand charges separately when they apply.
Frequently asked questions
Why is grid energy higher than battery energy?
Some electricity is lost during conversion, battery conditioning, and charging, so the meter records more energy than reaches the battery.
Should demand charges be included in the electricity rate?
Not automatically. Allocate demand charges separately or incorporate an appropriate effective rate for your site.
Can I use a time-of-use electricity price?
Yes. Use a weighted average or calculate separate peak and off-peak scenarios.
Does cost per mile include maintenance?
No. It covers electricity only.
How can I improve the monthly estimate?
Use measured route distance, charger-meter energy, and actual tariff data over several representative weeks.
