Chemical Drag Out Loss Calculator

Convert measured bath carryout to analyte mass, then subtract measured recovery. Compare solution volume with an allowance and price the unrecovered analyte on a matching basis.

What this calculator does

  • Estimate unrecovered analyte mass and replacement expense from measured bath drag out.

Formula used

  • Gross analyte (kg) = drag out (US gal) × 3.785411784 × concentration (g/L) ÷ 1,000
  • Unrecovered analyte = gross analyte − recovered analyte
  • Replacement cost = unrecovered analyte × analyte price
  • Recovered share = recovered analyte ÷ gross analyte × 100

Inputs explained

  • Measured Drag Out Volume: Bath solution carried out during the measured period.
  • Allowed Drag Out Volume: Entered bath carryout allowance for the same period.
  • Bath Analyte Concentration: Measured concentration of one named analyte in the bath.
  • Recovered Analyte Mass: Measured mass of that analyte recovered from carryout.
  • Analyte Replacement Price: Replacement price on the same analyte mass basis.

How to use the result

  • Best suited to measured drag out loss checks, analyte recovery comparisons.
  • Does not model precipitation, reaction or subsequent bath dilution. Recovery percentage is undefined when no analyte is carried out.

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

  • Which concentration should I use? Use measured bath concentration for one named analyte at withdrawal. Concentration and replacement price must describe the same mass basis.
  • How do I enter recovered material? Enter measured recovered analyte mass. A diluted recovery solution’s volume alone does not establish that mass.
  • Does this estimate discharge compliance? No. It accounts for measured carryout and recovery. Waste characterization and applicable discharge requirements need separate checks.
  • Which gallon does this use? Use US liquid gallons. One US gallon is exactly 231 cubic inches, giving 3.785411784 liters with the exact inch definition.
