Cost of raw materials consumed in the current period = raw materials purchased in the current period-raw materials in balance at the end of the period

Cost price = purchase price/(finished product rate * feeding standard (quantity))

Gross profit rate = (sales price-raw material cost)/ P > or

sales price = raw material cost+gross profit

gross profit margin = addition rate/.
