About this tool
The per-mile math: a 30 MPG gas car at $3.45/gal costs ~11.5¢/mile; a 3.5 mi/kWh EV at $0.15/kWh home charging costs ~4.3¢/mile — 60%+ cheaper, and more if you have time-of-use night rates. Fast chargers (30–50¢/kWh) narrow the gap. This calculator runs your actual rates and shows annual savings at your mileage, plus the maintenance context (EVs skip oil changes but tires/insurance can run higher).
FAQ
Is EV charging always cheaper?
Home charging almost always; DC fast-charging road trips can cost near gas prices. Public-network pricing varies wildly.
What about battery replacement cost?
Modern EV batteries typically outlast 8yr/100k+ warranties; budget-mentally amortize a $5–15k replacement over 10+ years for worst-case honesty.
