1. What is an Electric Car Cost per Mile Calculator?

Definition: This calculator estimates the running cost per mile for electric vehicles in the UK based on energy consumption and electricity rates.

Purpose: Helps EV owners and potential buyers understand and compare running costs with traditional vehicles.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Cost\_per\_mile} \) — Running cost per mile (£/mile)
• \( E\_per\_mile \) — Energy consumption (kWh/mile)
• \( Rate \) — Electricity cost (£/kWh)

Explanation: The energy consumption is multiplied by the electricity rate to determine the cost to drive one mile.

3. Importance of Cost per Mile Calculation

Details: Understanding per-mile costs helps with budgeting, comparing EVs to petrol/diesel cars, and evaluating charging options.

4. Using the Calculator

Tips: Enter your vehicle's energy consumption (typically 0.25-0.40 kWh/mile) and your electricity rate (default £0.30/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my car's energy consumption?
A: Check your vehicle's specifications or divide your battery capacity by the manufacturer's range estimate.

Q2: What's the average electricity rate in the UK?
A: Rates vary (typically £0.20-£0.40/kWh), with off-peak tariffs often cheaper. Check your energy provider for exact rates.

Q3: Does this include all running costs?
A: No, this only calculates energy costs. It doesn't include maintenance, insurance, or depreciation.

Q4: How does this compare to petrol cars?
A: EVs typically cost 3-5p/mile, while petrol cars average 10-15p/mile (at £1.50/litre and 40mpg).

Q5: Can I use this for public charging?
A: Yes, but use the specific charger's rate which may be higher than home electricity rates.
