How It Works
This calculator helps you determine the potential financial savings of owning an electric vehicle (EV) compared to a gasoline-powered car over a specified period. It's crucial for making an informed decision about your next vehicle purchase, considering both short-term and long-term operating costs.
The calculator works by comparing the total cost of ownership for an EV against a gas car. This typically involves subtracting the annual fuel/charging costs, maintenance, and relevant tax incentives/credits for the EV from those of the gas car, then projecting these differences over the chosen number of years.
Remember to consider all variables, including fluctuating electricity and gas prices, and potential future battery replacement costs for EVs. A common mistake is underestimating the impact of charging at home versus public charging, or overlooking available government incentives for EVs.
Example: Comparing a Tesla Model 3 to a Honda Civic over 5 years
- 1 Input the average fuel efficiency of the gas car (e.g., 35 MPG), average gas price ($3.50/gallon), average electricity rate ($0.15/kWh), EV efficiency (e.g., 4 miles/kWh), annual mileage (12,000 miles), and initial price difference ($10,000 more for EV) and any EV tax credit ($7,500).
- 2 The calculator determines annual gas cost ($1,200) vs. annual electricity cost ($450). It then factors in potential lower EV maintenance ($200/year less) and the initial price difference adjusted by the tax credit ($2,500 more for EV upfront).
- 3 After 5 years, the EV could result in a total savings of approximately $3,250, considering the initial higher purchase price offset by the tax credit and ongoing lower operating costs.
- 4 This example shows that while an EV might have a higher upfront cost, significant savings on fuel and maintenance, combined with incentives, can make it more economical in the long run.
