Calculation basis
Vehicle energy per mile is derived from the documented reference configuration. For MPGe-backed rows, EPA label consumption already includes charging losses, so the default extra adjustment is 0%. For battery/range-derived rows, CalcuRiver defaults to a 10% wall-loss adjustment. This is inspectable and adjustable on every state page.
monthly cost = monthly miles × 0.3240 vehicle kWh/mile × (1 + charging loss) × electricity $/kWh
