What will this design change strand in inventory?
Compare usable old-design stock, rework recovery and the cash cost of an immediate cutover.
Example scenario
Editable demonstration inputs, not verified industry benchmarks. Enable JavaScript to calculate your own scenario.
- Old-design inventory units
- 10,000
- Old units consumed before cutover
- 3,000
- Inventory book cost / unit
- $25
- Remaining units recoverable through rework
- 60 %
- Rework cash cost / recoverable unit
- $8
- Salvage value / unrecoverable unit
- $2
- Qualification & change implementation cost
- $35,000
Net incremental transition cash cost
Example result only, not a forecast or promise.
- Old-design units remaining
- 7,000
- Unrecoverable inventory book loss
- $64,400
- Reworkable inventory units
- 4,200
What to do with this result
Agree a physical cutover, traceability and depletion plan; accounting write-down and incremental cash are different impacts.

Calculation method
Stranded book value = remaining units × unrecoverable share × (book cost − salvage). Transition cash = reworkable units × rework cost + implementation − salvage proceeds.
Assumptions and limitations
- Example inputs are editable scenarios, not Aryo results or independently verified industry benchmarks.
- Recovered capacity is not booked revenue or automatic cash savings. Validate the bottleneck, quality and demand before monetizing output.
