Formula Yield Loss Calculator

Quantify weighed material lost during a completed batch. Enter documented losses, the complete ingredient charge, and your maximum target loss percentage.

What this calculator does

  • Measure documented material loss as a share of the weighed batch charge and compare it with your loss target.

Formula used

  • Loss = documented lost mass ÷ total charged mass × 100
  • Loss target headroom = maximum target loss − actual loss
  • Mass not recorded as lost = total charged mass − documented lost mass
  • Loss above target = max(0, lost mass − charged mass × target loss ÷ 100)

Inputs explained

  • Documented Lost Mass: Weighed material permanently lost within the batch accounting boundary.
  • Total Charged Mass: Sum of all ingredient additions from the batch record.
  • Maximum Target Loss: Approved maximum loss percentage for this product and process.

How to use the result

  • Best suited to filter and tank residue review, formula loss closeout.
  • Unmeasured emissions or residue make the reported loss incomplete. Mass not recorded as lost is not automatically saleable product.

Current U.S. benchmarks

  • Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
  • 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 reusable tank heel count as lost? Not if it is recovered within the stated accounting boundary. Track its transfer so the same material is not counted again in another batch.
  • Can I use gallons for both mass entries? No. This calculator fixes the basis in pounds. Weigh the quantities or convert each volume using the corresponding material density.
  • Is mass not lost the same as released yield? No. Held, sampled, or unreleased material may still be present. Use the batch yield calculator for released product recovery.
  • What sets an acceptable loss target? Your approved product and equipment standard sets the target. The calculator does not apply a universal coating loss allowance.
