About this calculator
This calculator compares the annual fuel cost of driving an electric vehicle versus a gas-powered vehicle and estimates how long it takes for EV fuel savings to offset a higher purchase price.
It focuses on operating costs—electricity versus gasoline—so you can understand when an EV starts saving you money based on your driving habits.
What each input means
- Miles per year is the estimated number of miles you drive annually. Higher mileage increases fuel and electricity usage.
- Gas price per gallon is your local average gasoline price. Higher gas prices increase the savings potential of an EV.
- Electricity rate per kWh is the cost of electricity where you charge your EV, measured in dollars per kilowatt-hour.
- Free charging (%) is the percentage of charging that costs you nothing (e.g., workplace charging, public chargers, or solar).
- Battery capacity (kWh) is the total energy capacity of the EV battery. Used to estimate energy usage per mile.
- Driving range (miles) is how far the EV can drive on a full charge. This helps determine energy consumption.
- EV purchase price is the upfront cost of the electric vehicle, including taxes or dealer fees.
- Gas vehicle MPG is the fuel efficiency of the gas vehicle, measured in miles per gallon.
- Gas vehicle purchase price is the upfront cost of the gas vehicle used for comparison.
How this calculator works
The calculator estimates energy usage per mile for the EV based on battery capacity and range. It multiplies this by annual miles and electricity cost, adjusted for free charging.
Gas vehicle fuel cost is calculated by dividing annual miles by MPG and multiplying by gas price.
Annual savings are the difference between gas fuel costs and EV electricity costs. The break-even point is calculated by dividing the purchase price difference by annual EV savings.
Factors that affect EV Savings
- Annual mileage – Higher mileage increases fuel savings and shortens the break-even period.
- Gas prices – Higher gas prices significantly improve EV cost advantages.
- Electricity costs – Lower electricity rates—or free charging—reduce EV operating costs.
- Vehicle efficiency – More efficient EVs and less efficient gas vehicles increase savings.
- Purchase price difference – A smaller upfront price gap leads to a faster break-even.
Key assumptions & limitations
- Constant prices – Fuel and electricity prices are assumed to remain constant.
- Excludes other costs – Maintenance, insurance, depreciation, and battery replacement costs are not included.
- Estimates only – Results are estimates, not financial advice.
- Fuel + electricity only – Savings are based solely on fuel and electricity costs.
