Cost per Accepted Square Metre in an Industrial Coating Pilot

Calculate coating pilot cost per accepted area, including rework and inspection, rather than dividing product cost by the area initially treated.

A pilot’s useful output is accepted surface area, not simply area coated. Including rejected or unfinished work in the denominator can make a weak process appear economical.

Define acceptance and cost scope

Agree the appearance, performance and documentation requirements before the trial. State whether costs include preparation, labour, coating, consumables, inspection, rework and disposal. Keep one-time development costs visible rather than mixing them silently with routine production estimates.

Use an explicit example

An illustrative pilot costs 1,200 currency units and treats 100 square metres. If 80 square metres are accepted at the reporting date, cost per accepted square metre is 1,200/80 = 15. Dividing by all treated area gives 12, which answers a different question.

Update after rework

If another 200 is spent and accepted area reaches 100 square metres, the cumulative cost becomes 1,400/100 = 14 per accepted square metre. Preserve the original first-pass acceptance result; the improved final ratio should not erase the rework history.

Interpret scale-up carefully

  • Separate learning time from repeatable production time.
  • Check whether pilot geometry represents the full job.
  • Include inspection and access constraints.
  • Use scenarios for uncertain yield and labour.

The pilot provides a structured estimate, not a guaranteed production price. Its value comes from showing which part of the process drives cost and whether a proposed improvement increases accepted output.
