EV vs Gas Car Cost Calculator

Compare real-world total ownership cost between electric and gasoline vehicles — with every assumption exposed

Free EV vs gas planning calculator for adjustable total ownership cost. Enter vehicle prices, fuel and charging rates, state fee, insurance, tire, maintenance, financing, depreciation, and federal incentive inputs. Preset rows are local defaults and need current vehicle, DMV, utility, insurance, and tax verification before purchase decisions.

Pro Tip: Use actual quotes where you have them: purchase price, insurance, home utility tariff, public charging rate, state registration fee, and any tax incentive. The sensitivity matrix helps show when fuel or electricity price changes would alter the cost winner.

How It Works

  1. Select Your Vehicles

    Choose local preset EV and gas vehicles or enter custom specifications. Replace preset price, MPG, kWh per mile, and resale assumptions with current vehicle listings, quotes, and official fuel-economy rows where available.

  2. Set Your Driving Profile

    Pick a preset scenario or customize annual miles, ownership period, highway percentage, winter efficiency penalty, and charging mix. Home, work, and public charging shares are normalized to 100%.

  3. Adjust Costs and Fees

    Set gas price, electricity rates for home/work/public charging, insurance, maintenance, tire costs, sales tax, financing terms, and state fee. State fee rows are planning defaults and should be verified against current DMV or statutory sources.

  4. Review Results

    The dashboard shows total cost of ownership, cost per mile, break-even year, cost breakdown, and yearly operating table. Flip points estimate gas-price or electricity-rate thresholds from the current inputs.

  5. Explore Sensitivity Analysis

    The gas price vs electricity rate matrix shows which vehicle wins across a range of energy costs. Green cells mean EV is cheaper, amber means gas is cheaper. This lets you plan for price volatility.

  6. Check Your Driver Fit Score

    The fit score is a planning heuristic based on charging access, mileage, climate, and driving patterns. Treat it as a prompt for follow-up checks, not a purchase recommendation.

Frequently Asked Questions

Many states charge EVs or plug-in hybrids a separate registration or road-use fee. This app uses a static planning table so the cost is visible, but you should verify the current amount against your state DMV, statute, or an updated tracker before making a purchase decision.
Cold weather can reduce EV efficiency and increase kWh consumed per mile. The calculator applies your winter penalty as an average annual adjustment, so replace the default with local or vehicle-specific data when you have it.
Insurance varies by driver, vehicle, carrier, garaging address, deductible, and claim history. The calculator lets you set separate insurance costs for both vehicles, but it does not predict a premium. Use actual quotes for decision work.
Vehicle weight, torque, tire type, alignment, roads, and driving style all affect tire wear. This calculator models tire life and tire cost separately so you can test the scenario with local tire quotes and expected replacement intervals.
IRS guidance says new, used, and commercial clean vehicle credits are not available for vehicles acquired after September 30, 2025. The calculator defaults federal incentive to $0. Enter an incentive only after current tax review.
Preset vehicle prices are local planning snapshots, not live market data. Verify current listings, dealer quotes, taxes, fees, and trade value, then enter your actual purchase price for decision work.
Flip points estimate the gas price or electricity rate where the current input set changes winners. They are planning thresholds, not forecasts.
Not directly in the default inputs. Add the actual installed charger cost to EV purchase price, financing, or a custom adjustment if it matters for your comparison.
Disclaimer: This calculator is preliminary planning support only, not purchase, tax, insurance, utility, fleet, or legal advice. Presets are local defaults with source gaps. Verify current vehicle data, DMV fees, utility tariffs, insurance quotes, financing terms, tax rules, and incentives before making financial decisions.
