Included and excluded costs

What this model includes

  • Parts, labor, and diagnostic service call fees in the repair quote.
  • State sales tax, delivery, installation, and haul-away fees for new units.
  • Manufacturer and utility Energy Star rebates.
  • Annual electricity savings based on yellow EnergyGuide labels and utility rates.
  • Remaining service life equity for the replacement appliance at the end of the repair horizon.

What is excluded or variable

  • Secondary breakdown risk: older repaired machines may suffer additional component failures before the horizon ends.
  • Water and sewer rate savings (relevant for high-efficiency washing machines and dishwashers).
  • Inflation in future electricity rates or replacement appliance prices.
  • Financing charges or credit card interest if the purchase is financed over time.
