Start with location and mileage
A ZIP code ties the estimate to local electricity rate data when a matching rate is available. Monthly miles usually matter more than full-battery cost because most drivers do not charge from 0% to 100% in normal use.
Estimate the monthly cost to charge an electric car in a specific ZIP code. Enter a vehicle, expected miles, and the share of charging you do at home versus public stations, then compare the result with a gasoline baseline.
Charging cost depends on energy use, not just battery size. The calculator starts with the selected model's efficiency, converts monthly miles into kWh, applies the ZIP-linked home electricity rate when available, and prices public charging separately. Gas savings use the same MPG and fuel-price assumptions each time, so changes in the result come from your inputs.

Home charging and public charging can carry very different prices. Choose the split closest to your normal charging pattern so apartment, workplace, road-trip, or garage charging miles are not treated as the same cost.
Monthly cost shows the expected bill amount. EV cost per mile makes it easier to compare vehicles, gasoline prices, and driving patterns before you rely on the annual savings number.
Treat the output as a planning estimate. It does not know your exact utility tariff, time-of-use window, public network membership price, idle fees, weather, or local taxes. For the source list and calculation framework, see Data Sources & Methodology.
