Weighing, Dosing & Loss-in-Weight Feeding calculator

Batch Reconciliation Calculator

Batch reconciliation capacity estimates how much good, in-spec output a dosing or loss-in-weight line can actually produce once availability and yield losses are removed from raw cycle count. It answers whether a feeding line can hit a production target and, when it cannot, whether uptime or yield is the bottleneck. Production planners and process engineers use it to set realistic commitments and to close the loop between material dispensed and material accounted for. Reconciliation is also a compliance staple in regulated batch processes where every gram must be tracked.

What this calculator does

  • Batch reconciliation capacity estimates how much good, in-spec output a dosing or loss-in-weight line can actually produce once availability and yield losses are removed from raw cycle count.
  • Use it when batch reconciliation in weighing, dosing and loss-in-weight feeding is being asked to take on more work and you need to know if there is room.
  • It multiplies units per cycle by available cycles for gross capacity, then applies uptime and yield to give good reconciled output.

Formula used

  • Gross batch reconciliation capacity = units per cycle × available cycles
  • Good capacity = gross capacity × uptime × yield

Inputs explained

  • Units dispensed per feed cycle:
  • Available feed cycles in the period:
  • Feeder uptime / availability:
  • First-pass yield of reconciled batches:

How to use the result

  • Use it when planning a batch campaign or reconciling planned versus actual good output on a dosing line.
  • It assumes uptime and yield are independent multipliers and stable across the period; it will overstate capacity if losses are correlated or if yield varies batch to batch.

Common questions

  • How do you calculate batch reconciliation capacity? Multiply units per cycle by available cycles for gross capacity, then multiply by uptime and yield. With 4 units/cycle, 480 cycles, 90% uptime and 97% yield, good output is 1,676 units from a gross of 1,920.
  • What is batch reconciliation in dosing? It is the accounting check that material dispensed equals material expected in finished good batches, after losses. A reconciliation gap points to leaks, unrecorded scrap, or feeder miscalibration.
  • What causes the gap between gross and good capacity? In the example, 90% uptime removes 192 units and 97% yield removes about 52 more, leaving 1,676 good units. Uptime loss is downtime and changeovers; yield loss is out-of-spec or scrapped batches.
  • What is a good yield for a dosing line? Well-controlled gravimetric dosing lines often run 97-99% first-pass yield. Below 95% usually signals recurring dose errors, material variability, or a control problem worth investigating.
  • Is uptime or yield the bigger lever here? In this case uptime costs 192 units versus 52 from yield, so recovering availability has the larger payoff. Always compare the two loss terms before deciding where to focus improvement effort.
