Boundary. This is a marginal charging-energy estimate. Fixed charges, taxes, riders and account-specific adjustments remain separate unless explicitly modeled.

What is being calculated?

Vehicle efficiency2.64 mi/kWh
Utility reference14.56¢ scheduled effective
Battery referencenot published in verified set

MPGe-backed vehicles use the EPA 33.7 kWh/gallon-equivalent conversion; EPA says the MPGe label value already includes charging losses, so CalcuRiver does not add another default loss. Where a manufacturer source gives usable battery and EPA-estimated range but not MPGe, the reference efficiency is battery ÷ range and a 10% wall-loss assumption is applied by default.

cost = miles × 0.378652 kWh/mile × 1.00 × $0.14562/kWh

Utility reference ≠ complete bill. This estimate applies the encoded marginal energy reference for ComEd. Fixed charges, taxes, account-specific riders, eligibility rules and unmodeled bill components remain separate unless the tariff engine explicitly models them.
