Estimate only. Home charging cost = vehicle kWh/100mi × residential electricity rate. Gas comparison uses a 28-mpg ICE baseline. Real cost varies by time-of-use rates, charger efficiency (~10% loss), driving conditions, and weather. Public DC fast charging is typically 2-4× home cost. Federal EV tax credit eligibility is not modeled — verify with the IRS Clean Vehicle Credit page and your dealer.
