Same annual mileage, two cars — see which one costs less to fuel each year.
Gas cars pay per gallon at a pump price that fluctuates often; EVs pay per kWh at electricity rates that vary by time of day and location — this calculator puts both on the same annual-mileage basis so they're directly comparable.
Local electricity rates, gas prices, and each vehicle's real-world efficiency all shift the outcome — what favors an EV in one region or season may look different elsewhere, so it's worth rerunning with your actual local prices.
