How to calculate work in process days

This calculator finds work-in-process days by dividing total WIP amount by units, expressing WIP as a time-based inventory measure.

How the calculation works

WIP days = Total amount ÷ Number of units.

Example

6,000 units of WIP value divided by 200 units/day of throughput: 6,000÷200 = 30 days.
