Job Order Costing Examples

This table uses the current randomized scenario. It defines each formula, shows the calculation, and states the answer.

This dashboard contains one randomized job order costing scenario. The values here feed the job cost sheet, predetermined overhead calculations, manufacturing cost flows, cost of goods manufactured report, cost of goods sold calculations, and service firm examples throughout the page.

Use the button to generate a new job order costing scenario with new material costs, labor costs, overhead estimates, allocation bases, inventory balances, and production activity.

Generate New Scenario

Concept Summary: Job order costing accumulates costs by distinct job, contract, customer, or project. Process costing accumulates costs by department or process when similar units move through repeated production steps.

Example A: Classify the costing system

Objective: Determine whether the live scenario uses job order costing or process costing.

Example B: Match production characteristics to costing method

Objective: Connect the production pattern to the accounting method.

Summary

Use job order costing when each job can be separately identified and traced. Use process costing when units are similar and move through repeated production processes.

Concept Summary: Source documents provide the evidence for costs added to a job cost sheet. Material requisitions trace direct materials. Labor time tickets trace direct labor. Applied overhead is assigned through the predetermined overhead rate.

Example A: Build the job cost sheet

Objective: Accumulate direct materials, direct labor, and applied manufacturing overhead for the selected job.

Example B: Solve for prime cost and conversion cost

Objective: Use the same job cost sheet to determine two common cost summaries.

Prime cost = Direct materials + Direct labor

Conversion cost = Direct labor + Applied manufacturing overhead

Summary

The job cost sheet becomes the central record for the job. It shows the manufacturing cost assigned to the job before completion, sale, and profit analysis.

Concept Summary: Manufacturing overhead is applied to jobs during the period using an estimated rate. The rate is set before actual total overhead is fully known, allowing jobs to receive timely overhead assignments.

Example A: Solve for the predetermined overhead rate

Objective: Determine the overhead assigned per allocation-base unit.

Predetermined overhead rate
= Estimated manufacturing overhead ÷ Estimated allocation base

Example B: Solve for applied manufacturing overhead

Objective: Determine how much overhead is assigned to the job.

Applied manufacturing overhead
= Predetermined overhead rate × Actual allocation base used by the job

Example C: Solve for the actual allocation base used

Objective: Rearrange the applied overhead formula to determine the activity used by the job.

Applied MOH = POHR × Actual allocation base

Actual allocation base
= Applied MOH ÷ POHR

Concept Summary: Manufacturing costs flow through inventory accounts. Raw materials become direct materials used. Direct materials, direct labor, and applied overhead enter Work in Process. Completed jobs move to Finished Goods. Sold jobs move to Cost of Goods Sold.

Example A: Trace costs from inputs to Work in Process

Objective: Identify how current manufacturing costs enter Work in Process.

Example B: Trace completed and sold jobs

Objective: Explain how completed jobs move from Work in Process to Finished Goods and then to Cost of Goods Sold.

Concept Summary: Applied manufacturing overhead is assigned to jobs using the predetermined rate. Actual manufacturing overhead is the indirect manufacturing cost actually incurred. The difference is closed through Cost of Goods Sold in this simplified treatment.

Example A: Determine the overhead variance

Objective: Compare applied overhead with actual overhead.

Overhead variance
= Applied manufacturing overhead − Actual manufacturing overhead

Example B: Close the variance to Cost of Goods Sold

Objective: Determine the COGS adjustment related to the overhead variance.

Concept Summary: Cost of goods manufactured measures the cost of jobs completed during the period. Cost of goods sold measures the cost of completed jobs sold during the period, adjusted for the overhead variance when the variance is closed to COGS.

Example A: Determine direct materials used

Objective: Use the raw materials inventory relationship to determine direct materials used in production.

Direct materials used
= Beginning raw materials + Raw materials purchased − Indirect materials − Ending raw materials

Example B: Determine cost of goods manufactured

Objective: Convert current manufacturing costs and WIP balances into completed-job cost.

Total current manufacturing costs
= Direct materials used + Direct labor + Applied manufacturing overhead

Cost of goods manufactured
= Total current manufacturing costs + Beginning WIP − Ending WIP

Example C: Determine adjusted cost of goods sold and gross profit

Objective: Use finished goods inventory and overhead variance adjustment to determine final COGS and gross profit.

Unadjusted COGS
= Beginning finished goods + COGM − Ending finished goods

Adjusted COGS
= Unadjusted COGS + MOH adjustment to COGS

Gross profit
= Sales revenue − Adjusted COGS

Concept Summary: Service firms use job order costing when work is organized by client matter, engagement, repair, implementation, or project. Direct labor is often the largest direct cost, and overhead is usually assigned through labor hours or labor dollars.

Example A: Build a service job cost

Objective: Apply job order costing to a service engagement using direct labor and applied overhead.

Example B: Match service source documents to job costs

Objective: Identify the evidence used to trace service costs to a client job.

Concept Summary: Journal entries record the same cost flow shown in the job order costing system. Costs move from Raw Materials, Factory Payroll, and Manufacturing Overhead into Work in Process, then Finished Goods, then Cost of Goods Sold.

Example A: Record materials, labor, and overhead into Work in Process

Objective: Show the journal-entry logic that assigns manufacturing costs to the job.

Example B: Record completion, sale, and overhead adjustment

Objective: Show the journal-entry logic that moves completed job cost to Finished Goods, then to Cost of Goods Sold, then adjusts COGS for overhead variance.

Summary

The journal entries mirror the cost flow. Work in Process accumulates manufacturing cost. Finished Goods receives completed jobs. Cost of Goods Sold receives sold jobs and the overhead variance adjustment.
