Beginning work in process of 5,900 units was 20% complete, 37,400 units were started and completed, and 7,300 ending units are 30% complete. What are equivalent units of production for conversion costs?

1. Equivalent units for conversion convert partial units into whole units using the percentage of conversion done in the month. 2. The opening group was already 20% complete, so the remaining 80% happens in May: 5,900 units times 80% is 4,720 equivalent units. 3. Units started and completed in May take 100% of their conversion in May: 37,400 units times 100% is 37,400 equivalent units. 4. Ending units are 30% complete, so only that share happened in May: 7,300 units times 30% is 2,190 equivalent units. 5. The total is 4,720 plus 37,400 plus 2,190, which is 44,310 equivalent units. 6. 44,700 units is the materials figure, where the opening group counts zero and the closing group counts in full. 7. 45,590 units would come from taking the opening group at its full 5,900 units, which double charges April conversion to May. 8. 43,300 units counts completed whole units and ignores the partly converted closing group. _Source: Jonick, Principles of Managerial Accounting (UNG Press, CC BY-SA 4.0), section 3.3 Process Costing Calculations for a Department in a Manufacturing Company_
