Guide
The cleanest way to compare a gasoline vehicle to an electric vehicle is to convert both into energy cost per mile. Gasoline vehicles consume gallons over distance, while EVs consume kilowatt-hours over distance. Once both are translated into annual operating cost using mileage, a direct comparison becomes possible.
The gasoline operating cost is:
$$\text{Gas Cost} = \frac{\text{Annual Miles}}{\text{MPG}} \times \text{Gas Price per Gallon}$$
The EV charging cost is:
$$\text{EV Cost} = \text{Annual Miles} \times \text{kWh per Mile} \times \text{Electricity Rate}$$
Annual savings are then:
$$\text{Savings} = \text{Gas Cost} - \text{EV Cost}$$
This comparison isolates fuel or energy expense only. It does not automatically include insurance, financing, depreciation, or maintenance differences unless they are modeled separately.
The more you drive, the more important per-mile energy economics become. A driver covering 20,000 miles per year experiences much larger fuel savings from efficiency improvements than a driver covering 6,000 miles. This is why high-mileage commuters often feel EV operating savings more strongly than low-mileage drivers.
Home charging rates, public fast-charging premiums, seasonal range changes, and battery efficiency all affect real-world EV cost. Likewise, gas price volatility affects combustion-vehicle budgeting. This calculator is strongest as a scenario planner: it helps users test assumptions rather than promising one fixed result.
