Exercise 17

Compute Equivalent Units: Weighted-Average Method

Missouri Corporation shows the following information concerning the work in process at its plant:

• Beginning inventory was partially complete (materials are 100 percent complete; conversion costs are 60 percent complete).

• Started this month, 180,000 units.

• Transferred out, 150,000 units.

• Ending inventory, 100,000 units (materials are 100 percent complete; conversion costs are 15 percent complete).

Required

a.Compute the equivalent units for materials using the weighted-average method.

---

b.Compute the equivalent units for conversion costs using the weighted-average method.

Step 1 of 3

All units cannot be wholly completed at the end of a specific period. Some units may be partially complete. Expenses (Material cost and conversion costs) might have been incurred on such units to the extent of their completion. Hence, in order to determine the actual production in a process, the concept of equivalent units is used. The partially completed units are multiplied with their percentage of completion and the resultant figure is considered as whole units produced.

Particulars	Number of units
Balance at the start of the period (a) = (c) + (d) – (b)	70,000
Add: Units input (b)	180,000
Less: Units transferred out (c)	150,000
Balance at the end of period (d)	100,000
