The Cost of Consequence in the calculator depends on the specific use case. If you primarily deal with finished goods, you may exclude this parameter.

However, if your business relies heavily on the timely availability of raw materials or subassemblies, including the Cost of Consequence could offer a more accurate representation of the financial impact of stockouts.

For example, if you are in the manufacturing industry, or with the production side of the supply chain where raw materials and subassemblies are critical, the Cost of Consequence is highly relevant.


Stockout Cost =(NDOS×AUSPD×PPU)+CC

NDOS = Number of days out of stock

AUSPD = Average units sold per day
