Yield Loss Calculator Guide
Estimate production losses from giveaway, yield shortfalls, and rejections -- then see the annualized financial impact.
Try Yield Loss CalculatorWhat Is the Yield Loss Calculator?
The Yield Loss Calculator helps you quantify three types of production loss: overfill giveaway (you ship more product than required), process yield shortfall (less output than expected from raw materials), and rejection loss (units scrapped or reworked). It converts each into a dollar value and shows which loss type is the biggest cost driver.
- Giveaway loss: the cost of overfilling containers beyond the target weight or volume
- Process yield loss: the gap between theoretical output and actual output from raw materials
- Rejection loss: the cost of scrapped, reworked, or downgraded units
- Annualized projection: multiply by event frequency to see the yearly financial impact
When to Use It
- After a production run to quantify how much money was lost to overfill, waste, or scrap
- During process improvement projects to set a baseline and measure improvement after changes
- For management presentations to show the business case for tighter fill control or waste reduction
- Quarterly OEE reviews where yield is one of the key performance metrics

Tips for Better Results
- Use actual check-weigh data for the average fill -- don't rely on the filler setpoint, which is often slightly different.
- Run the calculator monthly and plot the trend to catch creeping giveaway before it becomes a major cost.
- Pair this with SPC Quick Check on your fill weights to see whether overfill is caused by process instability or a shifted target.
