To calculate the value of the remaining inventory using the FIFO (First-In, First-Out), LIFO (Last-In, First-Out), and Weighted Average methods, we need to follow these steps:
Under the FIFO method, the oldest inventory costs are used up first when items are sold. Therefore, we will sell the devices from the earliest batches first.
Inventory before sale:
- Batch 1: 5 devices at $14,000 each
- Batch 2: 10 devices at $15,000 each
- Batch 3: 10 devices at $16,000 each
- Batch 4: 5 devices at $17,000 each
Devices sold: 12
Devices sold from:
- Batch 1: 5 devices at $14,000 each = $70,000
- Batch 2: 7 devices at $15,000 each = $105,000
Remaining inventory:
- Batch 2: 3 devices at $15,000 each = $45,000
- Batch 3: 10 devices at $16,000 each = $160,000
- Batch 4: 5 devices at $17,000 each = $85,000
Total value of remaining inventory (FIFO):
$45,000 + $160,000 + $85,000 = $290,000
Under the LIFO method, the most recent inventory costs are used up first when items are sold. Therefore, we will sell the devices from the latest batches first.
Devices sold: 12
Devices sold from:
- Batch 4: 5 devices at $17,000 each = $85,000
- Batch 3: 7 devices at $16,000 each = $112,000
Remaining inventory:
- Batch 3: 3 devices at $16,000 each = $48,000
- Batch 2: 10 devices at $15,000 each = $150,000
- Batch 1: 5 devices at $14,000 each = $70,000
Total value of remaining inventory (LIFO):
$48,000 + $150,000 + $70,000 = $268,000
Under the Weighted Average method, the average cost of all units is calculated and applied to the units sold and remaining.
Total cost of all devices:
- Batch 1: 5 devices at $14,000 each = $70,000
- Batch 2: 10 devices at $15,000 each = $150,000
- Batch 3: 10 devices at $16,000 each = $160,000
- Batch 4: 5 devices at $17,000 each = $85,000
Total cost = $70,000 + $150,000 + $160,000 + $85,000 = $465,000
Total number of devices = 30
Average cost per device = $465,000 / 30 = $15,500
Value of remaining inventory (Weighted Average):
18 devices remaining × $15,500 = $279,000
- FIFO Remaining Inventory Value: $290,000
- LIFO Remaining Inventory Value: $268,000
- Weighted Average Remaining Inventory Value: $279,000
These calculations provide the value of the remaining inventory under each accounting method, reflecting different approaches to inventory valuation.
