Stockout cost calculator
A stockout often costs more than the missing item.
This deliberately simple model adds three costs you control: lost margin, emergency expense and blocked work time. It does not pretend to price customer frustration or reputation damage.
Formula
The calculation used
Cost = missed units × margin per unit + emergency cost + downtime hours × hourly downtime cost.
Limit
A calculation is still a model
The result depends entirely on your inputs. It makes a decision explicit; it does not predict a late supplier, a surprise promotion or a week that suddenly decides to be special.
