Electric Car Gas Savings Calculator

Electric Car Savings Formula:

\[ Savings = \left( \frac{Gas\ Cost}{MPG} \times Miles \right) - \left( \frac{Electricity\ Cost}{kWh} \times \frac{kWh}{100\ miles} \times \frac{Miles}{100} \right) \]

Gas Cost:

currency/gallon

MPG:

miles per gallon

1. What is the Electric Car Gas Savings Calculator?

The Electric Car Gas Savings Calculator estimates annual fuel cost savings when switching from a gasoline-powered vehicle to an electric vehicle. It compares the operating costs of both vehicle types based on current fuel and electricity prices.

2. How Does the Calculator Work?

The calculator uses the savings formula:

\[ Savings = \left( \frac{Gas\ Cost}{MPG} \times Miles \right) - \left( \frac{Electricity\ Cost}{kWh} \times \frac{kWh}{100\ miles} \times \frac{Miles}{100} \right) \]

Where:

\( Gas\ Cost \) — Cost of gasoline per gallon
\( MPG \) — Fuel efficiency of gasoline vehicle (miles per gallon)
\( Miles \) — Annual driving distance
\( Electricity\ Cost \) — Cost of electricity per kWh
\( kWh/100\ miles \) — Energy consumption of electric vehicle

Explanation: The formula calculates the annual fuel cost for both vehicles and subtracts the electric vehicle cost from the gasoline vehicle cost to determine savings.

3. Importance of Fuel Cost Comparison

Details: Understanding potential fuel savings helps consumers make informed decisions about vehicle purchases, evaluate the financial benefits of electric vehicles, and plan long-term transportation costs.

4. Using the Calculator

Tips: Enter current local gas prices, your vehicle's MPG, annual mileage, electricity rates, and the electric vehicle's energy consumption. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What currency should I use?
A: Use your local currency consistently for both gas cost and electricity cost inputs.

Q2: Where can I find my electric vehicle's energy consumption?
A: Check the vehicle's specifications, EPA ratings, or manufacturer documentation for kWh/100 miles data.

Q3: Does this include maintenance savings?
A: No, this calculator only compares fuel costs. Electric vehicles typically have lower maintenance costs as well.

Q4: How accurate is this calculation?
A: It provides a good estimate based on your inputs. Actual savings may vary based on driving habits, temperature, and route conditions.

Q5: Should I consider electricity rate variations?
A: For more accurate results, consider time-of-use rates if your utility offers them, as charging during off-peak hours can significantly reduce costs.
