    Dealer Fee — What This Means

    Watch

    Your contract price includes a dealer fee to cover sales, financing, and overhead. Cash-equivalent $28,500 → Contract price $34,100 → implied dealer fee $7,700.

    Ask your installer whether this fee can be reduced or eliminated with a cash purchase.

    Nominal vs. NPV

    Why we discount future savings

    A dollar saved in the future is worth less today. We discount future cash flows at 6% to reflect the time value of money and investment risk.

    Nominal savings vs. NPV savings

    Nominal savings are total dollars saved. NPV savings are those dollars in today’s terms, so they are useful for comparing options fairly.
