The US Department of Energy calculator shows savings in an easy-to-grasp comparison display and is frequently updated by DOE.
Compare the financial costs of buying an EV versus buying a hybrid or standard gas powered car. It also shows the environmental benefits (measured in CO2 emissions and the equivalent number of trees!) of switching to an EV.
