Production costs are assigned to the units transferred out of WIP and to the units in ending WIP by multiplying the equivalent units by the per-unit cost. The following steps are involved:

1. Compute the equivalent units of production

2. Determine the cost per equivalent unit

3. Assign costs to ending WIP and cost of goods transferred out

Consider the T account showing the detail costs and units in the Mixing Dept using the FIFO costing method.

his example assumes that materials and conversion costs are added to the process evenly. When materials and conversion costs are added at different times in a process, the equivalent units for materials may be different than the equivalent units for conversion costs. For example, if materials are added at the beginning of a process, the materials may be 100% complete but unfinished for labor and overhead.

Fill in the schedule to show how the calculation changes when materials are added at the beginning of the Mixing Dept in the above example. Round cost per unit to four decimal places.

When FIFO is used, the key to remember is that the cost of beginning inventory is added to the cost of completed units rather than being added to the cost per equivalent unit calculation.

The steps are:

1. Compute the equivalent units of production

2. Determine the cost per equivalent unit

3. Assign costs to ending WIP and cost of goods transferred out

If materials and conversion costs are added at different times, the units are completed at different times in the process and the equivalent units should reflect that. If this is the case, the cost per equivalent unit is determined by separating the costs into material and conversion cost components and dividing the costs by the related equivalent units.

• Current period materials cost / Equivalent units for materials = Material cost per equivalent unit

• Current period conversion cost / Equivalent units for conversion costs = Conversion cost per equivalent unit

Ivy Manufacturing produces ketchup in a production process whereby units are indistinguishable from one another. The company uses process costing to calculate the cost of its products and also employs the FIFO method in its calculations.

The following information is available for August:

	Beginning work in process		Current period
Materials	$	5,690	$	28,942
Conversion costs		21,300		70,440
Total costs	$	26,990	$	99,382

Gallons of ketchup in process on August 1 (30% complete)*	12,200
Gallons of Ketchup completed and transferred out during August	48,000
Gallons of Ketchup in process on August 31 (25% complete)*	14,100
*All materials are added at the beginning of the process.
