Compare total ownership costs of gas vs electric vehicles including fuel, maintenance, and insurance.
A gasoline vehicle and an EV can trade places in the cost ranking once fuel, maintenance, and insurance are considered together. This tool places those ownership categories into one side-by-side comparison so a user can judge their combined financial effect instead of comparing pump and charging prices alone. Use equivalent driving and ownership assumptions for both vehicles. The common mistake is treating lower electricity expense as proof that the EV is cheaper overall; insurance or other included costs can narrow, erase, or reverse that advantage.
The tool builds one ownership-cost total for the gas vehicle and another for the EV from the cost categories shown in the comparison. Fuel or charging, maintenance, and insurance stay attached to the correct vehicle. Reading the two totals together shows whether an operating-cost advantage survives after the other included categories are counted.
Cost amounts expressed per month, per year, or for an entire ownership period need a common time basis before they can be combined meaningfully. Both vehicles should also represent the same travel demand and ownership duration. Otherwise, the apparent difference may come from comparing unlike scenarios rather than from a genuine gas-versus-electric cost difference.
No. The result compares the values and scope represented in the tool. It cannot guarantee future energy prices, repairs, premiums, or resale proceeds. Check whether both vehicles cover the same period and mileage, then review any major costs outside the displayed categories before treating the difference as a purchase decision.
Use the price that best represents where the EV will actually charge. If charging will be divided between home and paid public stations, neither rate alone is fully representative. A mileage-weighted or energy-weighted average is more informative when the tool accepts one electricity figure. Do not substitute a gasoline price for an electricity rate.
