Process Costing - Lost Units
LOSS UNITS refers to missing units at the end of the processing. Loss units are classified
into evaporation loss and spoilage loss. Evaporation loss refers to the normal decrease in
units or volume which is necessary or inherent in processing. Spoilage loss refers to
unwanted destruction or breakage of units during processing. Loss can discrete or
continuous. Discrete production loss is a reduction in units that occurs at a specific point
in a production process. If not specifically identifiable, discrete loss is assumed to have
occurred at the end of process. Continuous loss is any reduction in units that occurs
uniformly throughout a production process.
EUP COMPUTATION
1. Evaporation Loss is ignored and is not assigned EUP as if not placed into process and
is not valued.
2. Spoilage Loss (normal or abnormal) is assigned an equivalent unit of production and is
separately valued.
2. Subsequent
Department
a. Start/during the Unit Cost from Preceding Department multiplied by the
production Actual Normal Lost Units.
b. End of production (Unit Cost from the Preceding Department plus Unit cost
this Department) multiplied by the Equivalent Units of
Production of Normal Lost
C. Absorbing Units
