Here's how to calculate the correct value of the closing stock using the weighted-average method:
Step 1: Calculate the total units available for sale.
Totalunitsavailable=Openingstockunits+Purchasedunits−Returnedunits
Totalunitsavailable=4500+(7500+1500+820)−520
Totalunitsavailable=4500+9820−520
Totalunitsavailable=13800units
Step 2: Calculate the total cost of units available for sale.
Totalcostavailable=Openingstockvalue+Totalpurchasevalue−Valueofreturnedunits
Totalcostavailable=(4500×R50)+(7500×R55+1500×R58+820×R60)−(520×R50)
Totalcostavailable=R225000+(R412500+R87000+R49200)−R26000
Totalcostavailable=R225000+R548700−R26000
Totalcostavailable=R747700
Step 3: Calculate the weighted-average cost per unit.
Weighted−averagecostperunit=TotalunitsavailableTotalcostavailable
Weighted−averagecostperunit=13800unitsR747700
Weighted−averagecostperunit≈R54.18116perunit
Step 4: Calculate the value of the closing stock.
Valueofclosingstock=Closingstockunits×Weighted−averagecostperunit
Valueofclosingstock=4400units×R54.18116perunit
Valueofclosingstock=R238400
