- Annual mileage
- Modeled at 12,000 mi/yr unless a scenario specifies otherwise.
- Cost per mile
- $/gal ÷ MPG, or $/kWh ÷ (MPGe ÷ 33.7) for EVs.
- EV vs gas
- Compared at average US gas and residential electricity prices — fast-charging can be 2–3× higher.
- Maintenance
- Fuel cost only — EVs typically save another $400–$1,000/yr in service and brake wear.
