Most online EV vs gas calculators are incomplete, biased, or both. They either push EVs as always cheaper by ignoring state registration fees, insurance premiums, and winter efficiency loss — or they push gas vehicles by ignoring the maintenance and fuel savings that add up over years of ownership. This guide covers the real-world cost factors that actually determine which vehicle is cheaper for your situation.
