MPGe Calculator – Find Your Car’s Efficiency

Calculate your vehicle’s fuel efficiency with our MPG calculator tool.

How to Use the MPGe Calculator

To use this calculator, please follow these steps:

  1. Enter the total miles driven in the “Miles Driven” input field.
  2. Enter the number of gallons of fuel used in the “Gallons of Fuel Used” input field.
  3. Enter the number of kilowatt-hours of electricity used in the “Kilowatt-Hours of Electricity Used” input field.
  4. Click the “Calculate” button to get the result in miles per gallon equivalent (MPGe).

How It Works

The MPGe (Miles Per Gallon Equivalent) is a metric used to compare the energy consumption of electric or hybrid vehicles with traditional gasoline vehicles. The calculator uses the following steps to compute MPGe:

  • It takes the input miles driven, gallons of fuel used, and kilowatt-hours of electricity used.
  • It converts the kilowatt-hours of electricity into an equivalent gallon of gasoline using the conversion factor of 33.7 kWh per gallon.
  • It sums the actual gallons of fuel used and the equivalent gallons from electricity.
  • It divides the total miles driven by the total gallons equivalent to compute the MPGe.


The calculator has the following limitations:

  • It does not account for different driving conditions (e.g., city vs. highway driving).
  • It assumes all electricity used translates directly to miles driven without loss.
  • Results are based on user-entered data and may vary based on the accuracy of the inputs.

Use Cases for This Calculator

Calculate MPGe for a Hybrid Vehicle

Enter the total distance covered by your hybrid vehicle and the total energy consumption in kilowatt-hours. The MPGe calculator will provide you with the Miles Per Gallon Equivalent (MPGe) for your hybrid vehicle, allowing you to understand the energy efficiency in comparison to traditional gasoline-powered vehicles.

Determine MPGe for an Electric Vehicle

Input the total distance traveled by your electric vehicle and the total energy consumption in kilowatt-hours (kWh). The MPGe calculator will calculate the Miles Per Gallon Equivalent (MPGe) for your electric vehicle, giving you a clear idea of its energy efficiency compared to traditional gas-powered cars.

Compare Efficiency Between Two Vehicles

Enter the relevant data for two different vehicles, such as distance traveled and energy consumption. The MPGe calculator will provide you with the MPGe for each vehicle, allowing you to easily compare their energy efficiency and make an informed decision based on environmental impact and cost savings.

Plan Long Trips Based on Energy Efficiency

Before setting out on a long journey with your electric or hybrid vehicle, calculate the MPGe to estimate energy consumption. This will help you plan charging stops or evaluate the overall efficiency of your vehicle on the trip, ensuring a smooth and efficient travel experience.

Estimate Cost Savings with MPGe Data

By using the MPGe calculator, you can determine the energy efficiency of your vehicle and estimate the cost savings compared to traditional gasoline vehicles. Understanding the financial benefits of owning an electric or hybrid vehicle can help you make informed decisions about your transportation choices.

Track Energy Efficiency Over Time

Enter data about your vehicle’s energy consumption over multiple trips to track its energy efficiency trends. The MPGe calculator will provide you with insights into how efficient your vehicle is performing, allowing you to make any necessary adjustments to improve its overall performance.

Educate Yourself on Environmental Impact

By calculating the MPGe of your vehicle, you can learn more about its environmental impact in terms of energy consumption. Understanding how your vehicle’s efficiency contributes to or reduces harmful emissions can help you make more eco-conscious choices in your daily driving habits.

Optimize Charging Habits for Maximum Efficiency

Using the MPGe calculator, you can analyze the energy efficiency of your electric vehicle based on different charging habits. This information can guide you in optimizing your charging routine to maximize efficiency, reduce costs, and minimize environmental impact.

Share MPGe Data with Community or Social Networks

After calculating the MPGe of your vehicle, share the data with your community or social networks to raise awareness about energy efficiency. By sharing information about your vehicle’s energy consumption, you can inspire others to make more sustainable transportation choices.

Make Informed Decisions When Purchasing a New Vehicle

Before buying a new vehicle, use the MPGe calculator to compare different models’ energy efficiency and operating costs. Understanding the MPGe of various vehicles can help you make an informed decision based on performance, environmental impact, and long-term savings.
