Plating, Anodizing & Surface Treatment calculator

Plating Cost per Part Calculator

Find the invoiced plating cost carried by each accepted part. Enter plated area, the surface quote, lot setup and measured inspection counts.

What this calculator does

  • Price accepted plated parts from the surface quote, processed count, inspection count and one lot setup charge.

Formula used

  • Surface charge = area per part × surface price × processed parts
  • Lot cost = surface charge + lot setup
  • Accepted part cost = lot cost ÷ accepted parts
  • Acceptance (%) = 100 × accepted parts ÷ processed parts
  • Cost limit headroom = entered limit − accepted part cost

Inputs explained

  • Plated Area per Part: Unmasked surface area of one processed part from your drawing.
  • Surface Plating Price: Vendor price for the specified deposit and thickness.
  • Processed Parts: Count every part charged for plating.
  • Accepted Parts: Inspection count accepted from this plated lot.
  • Lot Setup Charge: One strike and rack setup charge on the invoice.
  • Accepted Part Cost Limit: Your approved purchasing limit per accepted plated part.

How to use the result

  • Best suited to accepted lot invoice allocation, quoted plated part purchasing.
  • Rework, freight and surcharges must already be included in the invoice amounts.

Current U.S. benchmarks

  • The producer price index for industrial chemicals stands at 336.006 (BLS, Aug 2026), up 13.3% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • The U.S. has 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).

Common questions

  • Should rejected parts reduce the plating invoice? No, this model charges every processed part. Change the surface quote only if your supplier contract actually credits rejected parts.
  • Is setup charged on every part? No, the lot setup charge is added once. The accepted part cost allocates it across the accepted count.
  • Does this predict the acceptance rate? No, acceptance comes from your inspection counts. The calculator reports their ratio without forecasting plating quality.
  • Which area belongs in the quote? Use the surface actually specified for plating on one part. Exclude masked regions when the supplier prices them separately.
