Use this calculator to turn operating assumptions into a clear estimate for fleet electrification energy cost. Enter the values that describe your vehicles, charging equipment, battery use, or route. The result panel shows the main planning figure plus supporting energy, capacity, time, distance, or cost metrics. The formula and example make each assumption visible, so you can compare scenarios without treating the output as a guaranteed field result.
The total combines metered charging energy with annualized fixed or demand charges entered by the user.
Exclude vehicle purchase, maintenance, charger capital, taxes, and time-of-use differences unless they are already reflected in the entered charges.
A 50-vehicle fleet driving 120 miles for 260 days at 2.8 mi/kWh uses 557,142.86 kWh. At $0.16/kWh plus $12,000 in annual charges, annual energy cost is $101,142.86.
The result changes most directly with the energy, distance, time, or capacity input that appears as a multiplier in the displayed formula.
Yes. Recent measured values generally make the result more useful, provided all values use the displayed units and cover comparable periods.
Enter zero where the field permits it. The calculator keeps valid zero-demand results separate from invalid zero denominators such as battery capacity or efficiency.
No. It includes only the losses represented by the input fields and formula. Review the note below the formula before using the estimate for planning.
Yes. Calculate the first scenario, record the results, then change the relevant inputs and calculate again. Keep units and time periods consistent.
| Input type | Use |
|---|---|
| Capacity or demand | Defines the size of the operating scenario. |
| Efficiency or recovery | Converts gross energy into useful energy. |
| Time, distance, or rate | Scales the result to the selected activity period. |
