Use this batch process yield loss calculator to turn shop-floor records into a decision-ready operating measure. Enter the production window, output, loss, or demand values that match the batch process being reviewed. The calculator returns the main result together with supporting rates or loss components, so you can trace what drives the number. It is designed for quick planning and performance checks without assuming an industry benchmark that may not fit your equipment, product mix, or inspection policy.
Gross loss = total input − good output. Net yield loss = max(0, gross loss − recovered units). First-pass yield = good output ÷ total input.
All time and output values must refer to the same measurement boundary.
Net yield loss isolates input that did not become good output and was not recovered through rework or reprocessing.
The monetary estimate values only net lost units. It does not include disposal, labor, energy, rework, or downtime unless those costs are included in the entered unit value.
From 10,000 input units and 9,400 good units, gross loss is 600. Recovering 150 leaves 450 net lost units; at $3.50 each, estimated net loss value is $1,575.
Use one consistent period for every time and output input, such as a shift, production order, or full day.
The monetary estimate values only net lost units. It does not include disposal, labor, energy, rework, or downtime unless those costs are included in the entered unit value.
Compare them only when the input definitions and ideal standards are equivalent; otherwise calculate each product or product family separately.
Reports may use scheduled time, run time, gross output, or good output differently. Match those definitions before comparing values.
Count output according to the labels in the calculator and keep recovered, rejected, and good units separate where those fields are provided.
| Input | Use |
|---|---|
| Total batch input (units) | Enter the value measured for the same production window. |
| Good output (units) | Enter the value measured for the same production window. |
| Value per lost unit (USD) | Enter the value measured for the same production window. |
| Recovered or reworked units (units) | Enter the value measured for the same production window. |
