The EV Charging Cost Calculator helps you estimate the cost to charge your electric vehicle. Simply fill in the fields above and click Calculate to get an instant result.
This calculator is part of Calculate Wiki’s Everyday Calculators collection.
What You’ll Need
- Battery Capacity (kWh)
- Current Charge (%)
- Target Charge (%)
- Electricity Rate ($/kWh)
- Charger Efficiency (%)
Formula Used
Energy Added = Battery Capacity × (Target % − Current %) ÷ 100
Energy from Grid = Energy Added ÷ Charger Efficiency
Cost = Energy from Grid × Electricity Rate
Example Calculation
Using example inputs — Battery Capacity = 75 kWh; Current Charge = 20 %; Target Charge = 100 %; Electricity Rate = 0.15 $/kWh; Charger Efficiency = 90 % — the EV Charging Cost Calculator returns:
| Value | Result |
|---|---|
| Energy added to battery | 60 kWh |
| Energy drawn from grid | 66.7 kWh |
| Estimated cost | $10.00 |
$10.00 to charge. 66.7 kWh drawn from the grid.
Helpful Information
Results from the EV Charging Cost Calculator are estimates based on standard formulas used in the everyday calculators field. For projects with significant cost, health, or safety implications, consider verifying results with a qualified professional.
