1. What is EV vs Petrol Cost Comparison?

This calculator compares the operating costs of electric vehicles (EVs) and petrol-powered vehicles on a per-kilometer basis. It helps consumers understand the cost differences between these two vehicle types.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• Electricity rate — Cost per kilowatt-hour of electricity
• kWh/100 km — EV energy consumption
• Petrol price — Cost per liter of petrol
• km/L — Petrol vehicle fuel efficiency

Explanation: The formulas convert both energy consumption metrics to a common per-kilometer cost for easy comparison.

3. Importance of Cost Comparison

Details: Understanding per-kilometer costs helps in making informed decisions about vehicle purchases and estimating long-term operating expenses.

4. Using the Calculator

Tips: Enter electricity rate in $/kWh, EV efficiency in kWh/100 km, petrol price in $/L, and petrol car efficiency in km/L. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Which is typically cheaper to operate?
A: EVs generally have lower per-km costs, but this depends on local electricity and petrol prices.

Q2: Does this include maintenance costs?
A: No, this only compares energy/fuel costs. EVs typically have lower maintenance costs.

Q3: How accurate are these calculations?
A: They provide estimates. Actual costs may vary based on driving conditions, vehicle load, etc.

Q4: Should I consider other factors?
A: Yes, also consider vehicle purchase price, range, charging infrastructure, and environmental impact.

Q5: How do I find my EV's kWh/100 km?
A: Check your vehicle's specifications or energy consumption display during driving.
