How to Calculate Work in Process Inventory
To accurately determine work in process (WIP) inventory, specific data points are essential. This calculation gives businesses insight into partially finished goods, crucial for effective inventory management.
Essential Data for Calculation
You need three critical values to compute ending WIP inventory: Beginning WIP Inventory, Manufacturing Costs, and Cost of Goods Manufactured (COGM). Each of these components plays a pivotal role in the formulation:
Work in Process Inventory Formula
To compute the ending WIP inventory, use the formula encapsulated within the tag for precision: Beginning WIP Inventory + Manufacturing Costs - COGM = Ending WIP Inventory. This equation involves addition and subtraction following this sequence, ensuring careful replacement of each variable with its corresponding actual value.
By gathering the necessary data and applying it to this straightforward formula, businesses can efficiently calculate their WIP inventory, aiding in more nuanced financial analysis and operational planning.
How to Calculate Work in Process Inventory
Understanding Work in Process Inventory
Work in Process (WIP) inventory represents materials and products partially through the manufacturing process but not yet completed. Calculating WIP accurately is crucial for understanding production efficiency and overall financial health of a manufacturing operation.
Step-by-Step Calculation of WIP Inventory
To calculate ending WIP inventory, you will start with the formula: Beginning WIP Inventory + Manufacturing Costs – COGM = Ending WIP Inventory. Each component of the formula is critical for accurate calculation.
Determining the Components
First, determine the Beginning WIP Inventory, which is the amount of WIP at the start of the accounting period, carried over from the previous period. Next, assess the Manufacturing Costs, which include all expenses related to producing finished products within the accounting period. Finally, calculate the Cost of Goods Manufactured (COGM), the total cost of finished goods produced.
Applying the Formula
With these values, use the WIP formula to find the Ending WIP Inventory, providing insight into the value of inventory still being processed at the end of the period. For instance, if your beginning WIP is $10,000 and manufacturing costs are $150,000, with COGM total at $250,000, your ending WIP would calculate as $10,000 + $150,000 - $250,000 = $-90,000. Correct negative values typically indicate an error in one of the figures or calculations.
Practical Example
Consider a scenario where a shoe brand starts with a WIP inventory of $100,000, incurs manufacturing costs of $150,000, and the cost of goods manufactured totals $150,000. The formula would yield an ending WIP of $100,000 + $150,000 - $150,000 = $100,000.
Correctly calculating work in process inventory allows businesses to manage their resources efficiently, maintaining balance between production inputs and outputs.

Calculating Work in Process Inventory: Practical Examples
Example 1: Simple Calculation with Given Values
When calculating work in process (WIP) inventory where you have directly given initial and final WIP values along with costs, use this formula: WIP = (Initial WIP + Manufacturing Costs - Cost of Goods Manufactured) - Final WIP. For example, if the initial WIP is $20,000, manufacturing costs are $50,000, cost of goods manufactured is $40,000, and the final WIP is $10,000, it calculates as $20,000 + $50,000 - $40,000 - $10,000 = $20,000.
Example 2: Calculating with Changes in WIP Units
When unit information is available, calculate using this approach: convert units to costs per unit before using the standard formula. Assume initial WIP units are 5,000 units at $6 each, 25,000 units added at $7 each, and 20,000 units completed. Final WIP is 5,000 + 25,000 - 20,000 = 10,000 units. If the cost didn’t change, final WIP value is 10,000 units x $7/unit = $70,000.
Example 3: Yearly WIP from Periodic Financials
For a yearly review, compute WIP from quarterly or monthly financial reports. Calculate each period’s WIP and use an average or end-of-period value for annual representation. For instance, compile four quarterly WIPs calculated as in Example 1, then average or summarize these for the yearly report.
Example 4: Adjustments for Efficiency Changes
Adjustments may be needed if there’s a significant change in manufacturing efficiency or costs. Recalculate unit costs if efficiency impacts are quantified. For example, if efficiency improvements decrease costs by 10%, recompute unit costs and reapply the new value in the WIP formula from Example 2.

In the WIP inventory formula, 'Beginning WIP Inventory' refers to the WIP inventory at the start of the accounting period. 'Manufacturing Costs' include the expenses for raw materials, labor, and overhead costs incurred during the accounting period. 'COGM' stands for Cost of Goods Manufactured, which is the total cost to produce the finished products. 'Ending WIP Inventory' is the value of partly finished goods at the end of the accounting period.
Why is it important to calculate the ending work in process inventory?
Calculating the ending WIP inventory is critical for inventory accounting, as it affects the balance sheet and helps in tracking the progress of manufacturing costs against the revenue generated from finished goods.
How do manufacturing costs affect work in process inventory?
Manufacturing costs, which include raw materials, labor, and overhead expenses, directly contribute to the value of WIP inventory by adding to the initial beginning WIP Inventory value before accounting for the cost of goods manufactured (COGM).
What is the difference between work in process inventory and finished goods inventory?
Work in process (WIP) inventory consists of unfinished products that are still in the production process, whereas finished goods inventory comprises items that have been fully manufactured and are ready to be sold.
