Mixing, Blending & Industrial Batch Processing calculator
Yield Loss Calculator
Check how much theoretical batch mass was lost and whether it exceeds your ceiling. Use confirmed loss and a complete mass reconciliation for the same batch.
What this calculator does
- Compare confirmed batch mass loss with your allowable loss ceiling.
Formula used
- Yield loss = lost mass ÷ theoretical mass × 100
- Ceiling margin = loss ceiling − yield loss
- Remaining mass = theoretical mass − lost mass
- Allowable loss = theoretical mass × loss ceiling ÷ 100
- Excess loss = max(0, lost mass − allowable loss)
Inputs explained
- Lost Batch Mass: Confirmed unrecoverable mass from the closed batch reconciliation.
- Theoretical Batch Mass: Expected total mass including every documented recipe addition.
- Yield Loss Ceiling: Maximum loss percentage in your product-specific operating standard.
How to use the result
- Best suited to batch mass closeout, loss investigation prioritization.
- The calculation does not identify evaporation, equipment residue, sampling, or disposal as the cause.
Common questions
- Does theoretical mass mean the original recipe charge? Only if there were no later additions. Include documented adjustments before reconciling the completed batch.
- Is remaining mass automatically good product? No. It includes everything not classified as loss. Product release depends on testing and the disposition of held material.
- Why is a loss above the theoretical mass rejected? A loss cannot exceed the entire accounted batch mass. Reconcile omitted additions, tare weights, units, or overlapping loss records.
- Where does the loss ceiling come from? Enter your own approved product or process limit. The calculator has no universal acceptable loss percentage.
