Methodology
How the estimate is calculated
EV cost uses electricity consumption, the entered electricity rate, and charging loss. Gas cost uses the entered MPG and gasoline price.
The comparison intentionally covers energy only. It does not assume maintenance, insurance, depreciation, financing, or incentive savings.
Important assumptions
- Efficiency values should represent comparable driving conditions.
- The five-year figure holds annual miles and energy prices constant.
Common questions
What to know about this estimate
Does this include EV maintenance savings?
No. Maintenance, insurance, registration, depreciation, and financing vary too much to hide inside an energy-cost comparison.
What electricity rate should I enter?
Use the rate applied to EV charging, including applicable per-kWh delivery charges. Do not include unrelated fixed monthly utility charges.
