EV vs Gas Vehicle Fuel Cost Comparison Calculator

Compare the annual and lifetime fuel costs between an electric vehicle (EV) and a gasoline-powered vehicle based on your driving habits, local electricity rates, and gas prices.

### Driving Habits

Annual Miles Driven

Ownership Period (Years)

### Electric Vehicle (EV)

EV Energy Consumption (kWh per 100 miles)

Typical EVs: 25–35 kWh/100 mi. Check your vehicle's EPA rating.

Electricity Rate ($ per kWh)

U.S. average ~$0.16/kWh (EIA, 2024). Check your utility bill.

Charging Efficiency (%)

Level 2 chargers are ~85–95% efficient; DC fast chargers ~80–90%.

### Gas Vehicle

Gas Vehicle Fuel Economy (MPG)

Check your vehicle's EPA MPG rating at fueleconomy.gov.

Gas Price ($ per gallon)

U.S. average ~$3.30–$3.60/gallon (EIA, 2024).

// Cost per mile (EV) const evCostPerMile = kwhPerMileWall * electricityRate;

// Lifetime EV fuel cost ($) const evLifetimeCost = evAnnualCost * ownershipYears;

// --- Gas Vehicle Cost Calculation --- // Gallons used per mile = 1 / mpg const gallonsPerMile = 1 / mpg;

// Annual gas cost ($) const gasAnnualCost = milesPerYear * gallonsPerMile * gasPrice;

// Cost per mile (gas) const gasCostPerMile = gallonsPerMile * gasPrice;

// Lifetime gas cost ($) const gasLifetimeCost = gasAnnualCost * ownershipYears;

// --- Savings --- const annualSavings = gasAnnualCost - evAnnualCost; const lifetimeSavings = gasLifetimeCost - evLifetimeCost; const savingsPct = ((annualSavings / gasAnnualCost) * 100);

#### Formulas Used

EV Cost per Mile (wall-to-wheel):

EV Cost/Mile = (kWh per 100 mi ÷ 100) ÷ (Charging Efficiency ÷ 100) × Electricity Rate ($/kWh)

Charging efficiency accounts for energy lost as heat during AC→DC conversion in the charger and battery.

EV Annual Fuel Cost:

EV Annual Cost = Annual Miles × EV Cost per Mile

Gas Cost per Mile:

Gas Cost/Mile = Gas Price ($/gal) ÷ MPG

Gas Annual Fuel Cost:

Gas Annual Cost = Annual Miles × Gas Cost per Mile

Lifetime Cost:

Lifetime Cost = Annual Cost × Ownership Years

Annual Savings:

Annual Savings = Gas Annual Cost − EV Annual Cost
