AR Coating Cost at 72% batch share with ar coating: a worked example

This worked example runs the ar coating cost numbers for a tougher week than the baseline: 72% batch share with ar coating instead of the typical 100%. Estimate anti-reflective coating cost for lenses or pairs using coated quantity, cost per lens, scope share, and fixed setup or certification cost.

The inputs for this scenario

  • Lenses receiving AR coating: 520 lenses (held at the documented default)
  • AR coating cost per lens: 6.75 $ / lens (held at the documented default)
  • Batch share with AR coating: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed AR setup and qualification cost: 480 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable AR coating cost = AR-coated lenses × AR coating cost per lens × batch share with AR coating.
  • Total AR coating cost works out to 3,007 $ at these inputs, and this is the headline figure for the scenario.
  • Average AR coating cost per lens works out to 5.78 $ / lens at these inputs.
  • Variable AR coating cost works out to 2,527 $ at these inputs.
  • Fixed AR setup and qualification cost works out to 480 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where batch share with ar coating sits at 100% and the headline result is 3,990 $, this scenario comes in 24.63% below the baseline at 3,007 $.
  • Use it to set AR upcharges, find the break-even batch size where setup is acceptably diluted, and compare in-house coating cost to outsourcing. 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.

Results at a glance

  • Total AR coating cost: 3,007 $ (headline result)
  • Average AR coating cost per lens: 5.78 $ / lens
  • Variable AR coating cost: 2,527 $
  • Fixed AR setup and qualification cost: 480 $
