1. What is the Gas vs Electric Cost Calculator?

This calculator compares the fuel cost per mile between gasoline-powered vehicles and electric vehicles (EVs). It helps consumers understand the operating cost differences between these two vehicle types.

2. How Does the Calculator Work?

The calculator uses two simple formulas:

Where:

• Gas price — Current price per gallon of gasoline
• MPG — Vehicle's miles per gallon efficiency
• Electricity rate — Cost per kilowatt-hour of electricity
• kWh/100 miles — EV's energy consumption rate

Explanation: The formulas convert both fuel types to a cost per mile basis for direct comparison.

3. Importance of Cost Comparison

Details: Understanding cost per mile helps in making informed decisions about vehicle purchases and estimating long-term operating costs. While EVs often have lower fuel costs, other factors like purchase price and maintenance should also be considered.

4. Using the Calculator

Tips:

• For gas vehicles: Use your actual observed MPG, not EPA estimates
• For EVs: Check your vehicle's efficiency rating (usually 25-35 kWh/100 miles)
• Use your local electricity rate (check your utility bill)
• Update gas prices frequently as they fluctuate

5. Frequently Asked Questions (FAQ)

Q1: Which is typically cheaper to operate?
A: EVs generally have lower fuel costs per mile, especially in areas with low electricity rates and high gas prices.

Q2: Does this include maintenance costs?
A: No, this only compares fuel costs. EVs typically have lower maintenance costs but higher upfront costs.

Q3: How accurate are these calculations?
A: They provide good estimates, but actual costs may vary based on driving habits, terrain, weather, etc.

Q4: Should I consider time-of-use electricity rates?
A: If your utility has variable rates, charging during off-peak hours can significantly reduce EV operating costs.

Q5: What about hybrid vehicles?
A: For hybrids, use their combined MPG rating in the gas cost calculation.
