Weighing, Dosing & Loss-in-Weight Feeding calculator

Batch Ingredient Mass Reconciliation Calculator

Reconcile ingredient entering and leaving a defined dosing-system boundary. Enter opening inventory, additions, verified delivery, closing inventory and recorded waste.

What this calculator does

  • Reconcile ingredient entering and leaving a defined dosing-system boundary.

Formula used

  • Available ingredient = Opening inventory + Added mass
  • Accounted ingredient = Dispensed mass + Closing inventory + Recorded waste
  • Unexplained difference = Available ingredient − Accounted ingredient

Inputs explained

  • Opening Material in System: Ingredient inventory inside the defined boundary before the batch.
  • Ingredient Added During Batch: Verified material additions across the same boundary.
  • Verified Dispensed Ingredient: Ingredient transferred out as measured batch delivery.
  • Closing Material in System: Measured residual ingredient at the end of the batch.
  • Recorded Waste and Samples: Documented material removed without entering batch delivery.

How to use the result

  • Best suited to batch material closure, hopper inventory investigations.
  • The difference does not identify theft, leakage, contamination or scale bias.

Common questions

  • Should retained material in a screw be included? Yes. Include retained ingredient inside the chosen system boundary in closing inventory.
  • Why allow a negative difference? It exposes inconsistent measurements or boundaries instead of silently clamping the balance to zero.
  • Can packaging tare be included? No. All entries must be ingredient net mass on a consistent basis.
  • Does recorded waste count as missing material? No. It is already explained by a documented withdrawal and belongs in the accounted total.
