EV vs Gas Fuel Cost Calculator

Compare annual driving energy cost using your mileage, local electricity price and gasoline price. The result isolates the energy needed to move the vehicle so you can see how strongly local tariffs, fuel prices and annual mileage affect the operating-cost gap. Use your real home-charging rate where possible, especially if you have time-of-use pricing.

What it does not include

Purchase price, insurance, depreciation, public fast-charging premiums, maintenance and taxes are outside this simple energy comparison. EV charging losses and real-world fuel economy can also move the result, so treat the output as a transparent energy-cost comparison rather than a full vehicle total-cost-of-ownership model.
