Charger Quote Margin with quoted charger or site-package price of 142,500 $: a worked example

This worked example runs the charger quote margin numbers for a tougher week than the baseline: quoted charger or site-package price of 142,500 $ instead of the typical 285,000 $. Calculate quote margin for EV charging equipment by comparing quoted selling price with required delivered cost.

The inputs for this scenario

  • Quoted charger or site-package price: 142,500 $ (the input this scenario stresses; the baseline uses 285,000)
  • Required delivered charger cost: 231,000 $ (held at the documented default)
  • Reference quote price: 285,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Quote gross margin dollars = quoted charger price - required delivered charger cost.
  • Charger quote gross margin works out to -31.05 % at these inputs, and this is the headline figure for the scenario.
  • Quote gross margin dollars works out to -88,500 $ at these inputs.
  • Quoted charger or site-package price works out to 142,500 $ at these inputs.
  • Required delivered charger cost works out to 231,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where quoted charger or site-package price sits at 285,000 $ and the headline result is 18.95 %, this scenario comes in 264% below the baseline at -31.05 %.
  • Use it when bidding a charger or full site package — single DC fast charger up to a multi-port depot — before the quote is submitted. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
