Finish Coating Cost at 58% finish scope included: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop finish scope included to 58%, then walk the calculation through step by step. Estimate coating, paint, stain, powder coat, anodized hardware finish, or special color cost for doors, frames, and hardware components.

The inputs for this scenario

  • Doors, frames, or hardware parts finished: 100 finished units (held at the documented default)
  • Finish cost per unit: 45 $ / finished unit (held at the documented default)
  • Finish scope included: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed color match, setup, or rack cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Included variable finish cost = doors, frames, or hardware parts finished × finish cost per unit × finish scope included.
  • Total finish coating cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Finish cost per finished unit works out to 28.6 $ / piece at these inputs.
  • Included variable finish cost works out to 2,610 $ at these inputs.
  • Fixed color match, setup, or rack cost works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where finish scope included sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to finish scope included, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes one uniform per-unit finish cost; a batch mixing simple primer parts with multi-coat specialty finishes needs separate runs or a weighted average to be accurate.

Results at a glance

  • Total finish coating cost: 2,860 $ (headline result)
  • Finish cost per finished unit: 28.6 $ / piece
  • Included variable finish cost: 2,610 $
  • Fixed color match, setup, or rack cost: 250 $
