How this is calculated
Losses by department (currency)
Sum mutually exclusive loss causes for each department.
Total shrink (currency)
Add all department loss entries.
Waste share of shrink (%)
Divide recorded waste by total loss.

Assumptions and limits
All losses are valued on the same cost basis and assigned to one cause only; excludes offsetting recoveries.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Losses by department (currency); Total shrink (currency); Waste share of shrink (%). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: All losses are valued on the same cost basis and assigned to one cause only; excludes offsetting recoveries.
