What this tool does
A stopped line costs twice: the margin on the units not made, and the wages, rent and energy that continue regardless. Putting both into one hourly figure is usually what justifies a spare part on the shelf.
Formula
cost = hours stops × (lost margin per hour + fixed cost per hour)
