1. What is the EV vs Gas Cost Calculator?

This calculator compares the per-mile operating costs of electric vehicles versus gasoline-powered vehicles. It helps consumers understand the fuel cost savings potential of switching to an electric vehicle.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• Electricity Rate — Cost per kilowatt-hour ($/kWh)
• Energy Consumption — EV efficiency (kWh/mile)
• Gas Price — Cost per gallon of gasoline ($/gal)
• MPG — Vehicle miles per gallon (miles/gal)

Explanation: The calculator shows the direct fuel/energy costs for each vehicle type, helping compare operating expenses.

3. Importance of Cost Comparison

Details: Understanding per-mile costs helps evaluate the financial benefits of EV ownership, especially when electricity prices and gas prices fluctuate.

4. Using the Calculator

Tips: Enter your local electricity rate, your EV's energy consumption (typically 0.25-0.35 kWh/mile), current gas prices, and your gas vehicle's MPG. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical energy consumption for EVs?
A: Most EVs consume 0.25-0.35 kWh per mile, with efficient models as low as 0.20 kWh/mile and larger vehicles up to 0.40 kWh/mile.

Q2: Should I use home charging or public charging rates?
A: For most accurate personal comparison, use your home electricity rate. Public charging may be more expensive.

Q3: Does this include maintenance cost differences?
A: No, this only compares fuel/energy costs. EVs typically have lower maintenance costs which aren't reflected here.

Q4: How do I find my electricity rate?
A: Check your electric bill for the cost per kWh - this is often between $0.10-$0.30 depending on location.

Q5: Why compare cost per mile?
A: Cost per mile normalizes the comparison regardless of how much you drive, making it easier to understand potential savings.
