Calculate Gas Savings For Electric Car

Savings Formula:

\[ Savings = Gas\ Cost - Electric\ Cost \] \[ Gas\ Cost = \frac{Miles}{MPG} \times Price\ Per\ Gallon \] \[ Electric\ Cost = \frac{Miles}{MPGe} \times Price\ Per\ kWh \times Battery\ Efficiency \]

1. What is Gas Savings Calculation?

The gas savings calculation compares the cost of driving a gasoline-powered vehicle versus an electric vehicle over a specified distance. It helps consumers understand the potential financial benefits of switching to an electric vehicle.

2. How Does the Calculator Work?

The calculator uses the following formulas:

\[ Savings = Gas\ Cost - Electric\ Cost \] \[ Gas\ Cost = \frac{Miles}{MPG} \times Price\ Per\ Gallon \] \[ Electric\ Cost = \frac{Miles}{MPGe} \times Price\ Per\ kWh \times Battery\ Efficiency \]

Where:

$ Miles $ — Distance driven in miles
$ MPG $ — Gas vehicle miles per gallon
$ MPGe $ — Electric vehicle miles per gallon equivalent
$ Price\ Per\ Gallon $ — Cost of gasoline per gallon
$ Price\ Per\ kWh $ — Cost of electricity per kilowatt-hour
$ Battery\ Efficiency $ — Charging efficiency factor (typically 0.85-0.90)

Explanation: The calculation accounts for both vehicles' energy efficiency and local energy prices to determine the cost difference.

3. Importance of Comparing Fuel Costs

Details: Understanding fuel cost differences helps consumers make informed decisions about vehicle purchases, budget for transportation expenses, and evaluate the financial impact of switching to electric vehicles.

4. Using the Calculator

Tips: Enter the distance you plan to drive, your gas vehicle's MPG, the electric vehicle's MPGe rating, local gas and electricity prices, and the battery efficiency (typically 0.85 for most EVs). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is MPGe?
A: MPGe (Miles Per Gallon Equivalent) is a metric that allows consumers to compare the energy consumption of electric vehicles with traditional gasoline vehicles.

Q2: What is a typical battery efficiency value?
A: Most electric vehicles have a charging efficiency between 85-90%, meaning 85-90% of the electricity from the grid actually charges the battery.

Q3: Does this account for all ownership costs?
A: No, this calculator only compares fuel costs. Total cost of ownership should include maintenance, insurance, depreciation, and potential tax incentives.

Q4: How accurate is this calculation?
A: The calculation provides a good estimate but actual results may vary based on driving conditions, vehicle maintenance, and fluctuations in energy prices.

Q5: Should I use local or average energy prices?
A: For the most accurate results, use your local electricity rate and current gas prices in your area.
