Gross profit margin
Comparing gross profit margin over time
If gross profit has not increased in line with sales revenue, you need to
establish why not. Is the discrepancy due to:
•
increased ‘purchase’ costs: if so, are the costs under the entity’s
control (i.e. does the entity manufacture the goods sold)?
•
inventory write-offs (likely where the entity operates
in a volatile
marketplace, such as fashion retail)? or
•
other costs being allocated to cost of sales – for example, research
and development (R&D) expenditure?
