Utilization formula
Used length = original length − remaining length
Utilization % = used length ÷ original length × 100
Remaining % = 100 − utilization %
Utilization % = used length ÷ original length × 100
Remaining % = 100 − utilization %
Worked example
From a 1,000 m drum with 275 m remaining, 725 m has been used. Drum utilization is 72.5% and remaining inventory is 27.5%.
Why percentage is useful
A percentage gives a common reference for comparing drums of different original lengths. It can support stock reviews without confusing drum size with actual remaining quantity.
