c. P 17,500
Solution: AC inventory: [20 + (150,000 ÷ 10,000)] x (11,000 – 10,500) Incidentally, VC inventory: 20 (500)
Note: Once normal capacity is given, the unit FFOH is based on normal production. A capacity or volume variance
explains any difference between the normal production used and actual production attained.
b. P 20,000 favorable
Solution: Volume (Capacity) Variance: (Actual Production – Normal Production) unit FFOH
= (11,000 – 10,000) (200,000 ÷ 10,000) Favorable: Actual Production > Normal Production
Note: Volume or capacity variable only exists under AC. No volume variance exists under variable costing (VC).
Note 1: If Production > Sales, then Ending Inventory > Beginning Inventory, and also, AC profit > VC profit.
Note 2: Inventory cost under AC > Inventory cost under VC, regardless of production and sales.

How much lower would Margarita’s profit be if it used variable costing (VC) instead of absorption costing (AC)?
a. P 36,000
b. P 54,000
c. P 68,000
d. P 94,000
Solution: ∆ income = ∆ Inventory x unit FFOH = (100,000 – 80,000) x (180,000 ÷ 100,000)
b. P 1,000
Solution: Traditional costing (based on DL hours): 50,000 [200 ÷ (200 + 200)] ÷ 25 units
a. P 500
Solution: ABC: 50,000 [5 ÷ (5 + 15)] ÷ 25 units
NOTE: In a highly competitive industry where pricing is largely based on prevailing market price, target cost is
computed as follows: Target cost = market price – desired profit
