EV vs Gas: Cost Per Mile Comparison

Electric vehicles (EVs) and gasoline cars are locked in a cost-per-mile showdown

ThisCalc's EV vs Gas Cost Per Mile calculator provides a framework to quantify these expenses By inputting fuel prices, maintenance costs, and driving patterns, users can determine which power source offers true economic value The tool accounts for variables like energy efficiency, charging frequency, and fuel economy ratings, creating a holistic view of transportation costs This analysis is critical for consumers weighing long-term savings against upfront costs in the evolving automotive landscape.

Breaking Down the Cost Per Mile Formula

The core calculation compares energy costs to traditional fuel expenses. For EVs, multiply kilowatt-hours (kWh) per mile by electricity rates. Gasoline vehicles use gallons per mile multiplied by fuel prices. This /calculators/ev-vs-gas-cost-per-mile tool standardizes these metrics, allowing direct comparisons across vehicle types and regions.

Energy efficiency varies widely: EVs typically achieve 3-4 miles per kWh, while gasoline engines average 20-30 mpg. These differences compound over time, making the calculator essential for accurate long-term cost projections. The tool also factors in charging infrastructure costs, which can add 10-20% to EV operating expenses in some regions.

Electricity Rate Variability

Electricity costs depend on location, time of use, and grid infrastructure. Residential rates average $0.13/kWh, but commercial rates can exceed $0.25/kWh. The calculator includes regional rate inputs to reflect these variations accurately.

Key Variables in the Cost Analysis

Three primary factors shape the calculation: energy efficiency metrics, fuel pricing data, and vehicle-specific costs. EVs benefit from lower maintenance expenses but face higher upfront costs. Gasoline vehicles have more predictable fuel costs but require regular maintenance. The tool allows users to input these variables to create a personalized cost model.

For example, a 2022 Tesla Model 3 with 3.5 miles/kWh and $0.15/kWh electricity costs $0.05/mile. A 25 mpg gasoline car at $3.50/gallon would cost $0.14/mile. These figures shift based on driving habits, fuel prices, and charging infrastructure access.

Calculating Your Personalized Cost Per Mile

{
  "ev": {
    "kWh_per_mile": 3.2,
    "electricity_rate": 0.14,

  "gas": {
    "mpg": 28,
    "fuel_price": 3.65,
    "maintenance_cost": 0.05
  }
}

The calculator uses this structure to compute total costs. EVs show lower per-mile costs in regions with cheap electricity, while gasoline vehicles may be more economical in areas with high grid rates. The tool also includes a sensitivity analysis to show how changes in variables impact overall costs.

Real-World Cost Per Mile Examples

In California, EVs typically cost 60-70% less per mile than gasoline vehicles. A 2023 Chevrolet Bolt EV with 3.8 miles/kWh and $0.12/kWh electricity costs $0.05/mile. Gasoline vehicles in the same region average $0.18/mile. These figures include maintenance costs but exclude charging infrastructure expenses.

In contrast, Texas EV owners pay $0.06/mile with $0.10/kWh electricity, while gasoline vehicles cost $0.15/mile. The calculator helps users identify regional cost advantages and plan for charging infrastructure investments where necessary.

Long-Term Cost Implications

Over 150,000 miles, EVs save $10,000-$15,000 in fuel costs compared to gasoline vehicles. This assumes average electricity rates and fuel prices. The calculator includes a lifetime cost analysis tool to project savings over vehicle lifespans. Maintenance cost differences also compound over time, with EVs showing 40-50% lower annual maintenance expenses.

However, upfront costs for EVs remain higher, with a 15-20% price premium over comparable gasoline vehicles. The calculator helps users balance these initial costs against long-term savings, considering factors like tax credits and charging infrastructure ROI.
