Understanding Fuel vs Electricity Cost Parity

This calculator helps you compare the operating costs between traditional fuel vehicles and electric vehicles. Understanding these costs is essential for making informed decisions about vehicle purchases and estimating long-term savings.

Why This Matters

Electric vehicles typically have lower operating costs per mile/kilometer due to higher energy efficiency and cheaper electricity compared to gasoline/diesel. However, the actual savings depend on local fuel and electricity prices, vehicle efficiency, and driving patterns.

Step-by-Step Guide

Select your preferred unit system (Metric/Imperial)
Enter your fuel vehicle's efficiency and local fuel price
Enter your electric vehicle's efficiency and electricity rate
Specify the distance you want to compare (annual mileage or specific trip)
Review the cost comparison and break-even analysis

Real-World Examples

Example 1: Daily Commuter

40-mile daily commute, 30 MPG gasoline car vs 4 mi/kWh EV. Gas at $3.50/gal, electricity at $0.15/kWh. Annual savings: ~$900 with EV.

Example 2: Long-Distance Driver

20,000 miles annually, 25 MPG SUV vs 0.35 kWh/mi EV. Diesel at $4.00/gal, electricity at $0.12/kWh. Annual savings: ~$1,600 with EV.

Reference Data

Vehicle Type	Typical Fuel Economy	Typical EV Efficiency
Compact Car	30-40 MPG	4-5 mi/kWh
SUV	20-30 MPG	2.5-3.5 mi/kWh
Pickup Truck	15-25 MPG	2-3 mi/kWh

Frequently Asked Questions

How accurate are these calculations?

The calculations provide theoretical estimates based on the inputs provided. Real-world results may vary due to driving style, weather conditions, vehicle maintenance, and actual energy prices.

Does this include maintenance costs?

No, this calculator only compares fuel/electricity operating costs. EVs typically have lower maintenance costs (no oil changes, fewer moving parts), but those are not included here.

What about public charging costs?

This calculator assumes home charging rates. Public DC fast charging can be 2-3x more expensive than home charging, which would reduce EV savings for frequent public charging users.

How do I find my vehicle's efficiency?

For fuel vehicles: check your owner's manual or EPA ratings. For EVs: consult the manufacturer's specifications or your vehicle's energy consumption display. Real-world efficiency may differ from official ratings.

Formulas & Assumptions

Fuel Cost Calculation: (Distance ÷ Fuel Economy) × Fuel Price

EV Cost Calculation: (Distance × Energy Consumption) × Electricity Price

Unit Conversions: 1 US gallon = 3.78541 liters, 1 mile = 1.60934 kilometers

MPG to L/100km: 235.2145 ÷ MPG

L/100km to MPG: 235.2145 ÷ L/100km

Rounding: All calculations rounded to 4 decimal places, displayed to 2 decimal places
