EV Charging Cost Formula:
| From: | To: |
The Electric Car Cost Per Mile calculation helps EV owners understand their driving expenses by calculating the cost of electricity required to travel one mile. This provides a clear comparison to traditional gasoline vehicle operating costs.
The calculator uses the EV charging cost formula:
Where:
Explanation: The formula multiplies the vehicle's energy efficiency by the local electricity rate to determine the cost for each mile driven.
Details: Understanding per-mile costs helps EV owners budget effectively, compare operating costs with gasoline vehicles, and make informed decisions about charging strategies and vehicle usage.
Tips: Enter kWh per Mile (typically 0.25-0.40 kWh/mile for most EVs) and your local electricity rate in $/kWh. Both values must be positive numbers.
Q1: What is a typical kWh per Mile for electric vehicles?
A: Most EVs consume between 0.25-0.40 kWh per mile, with smaller vehicles typically being more efficient and larger SUVs consuming more energy.
Q2: How does EV cost per mile compare to gasoline vehicles?
A: EVs typically cost 3-5 cents per mile, while gasoline vehicles often cost 10-15 cents per mile, making EVs significantly cheaper to operate.
Q3: Does this include charging efficiency losses?
A: This calculation uses wall-to-wheel energy consumption. For precise results, consider charging efficiency (typically 85-90%) in your kWh per Mile input.
Q4: How can I find my exact kWh per Mile?
A: Check your vehicle's trip computer, divide total kWh used by miles driven, or consult your EV's specifications for efficiency ratings.
Q5: Should I use home or public charging rates?
A: For daily cost calculations, use your home electricity rate. For trip planning, consider both home and public charging rates as they can vary significantly.
