CleanEnergyMath.com was built to answer one specific question simply: how much would you actually save switching from a gas car to an EV, given your own commute and your own local energy prices — not a national average that may not reflect your situation.
The calculator uses your zip code to estimate your local electricity rate and nearby gas prices, then compares monthly and annual costs for both a gas vehicle and an EV charged at home, based on the driving distance and vehicle efficiency you enter.
