 Relevance and the materiality test determine if a cost is a
Product Cost…
Relevance
A cost should be allocated as a
Product Cost if it will influence the
decision-making about stock
• Will allocating the cost better
help management identify its
actual cost of sales?
• Will allocating the cost help
management make a better
decision on how much to sell it
for?
Materiality
A relevant cost should only be
allocated as a Product Cost if it is
large enough (material) to influence
decision-making
• Include material costs that will
influence decision-making
• Exclude immaterial costs that
will not influence decision-
making
