Chapter 19: Job Order Costing — Detailed Notes

📌 Overview

Job Order Costing is used when products are manufactured based on specific customer orders. Each job is treated as a unique project with separate cost tracking for materials, labor, and overhead.


🏭 Production Activities in Job Order Costing

Direct Materials:

Identifiable with a specific job.

Direct Labor:

Employee effort that directly converts materials to finished products for a specific job.

Factory Overhead:

Indirect manufacturing costs shared across multiple jobs.


🔁 Manufacturing Cost Flows

Subsidiary Records:

Store cost data for each individual job.

Job Cost Sheet:

Main document tracking materials, labor, and overhead for each job.

Linked to accounts in the general ledger.


📦 Materials and Labor Costs

Receiving Report:

Source document confirming receipt of materials.

Materials Ledger Cards:

Updated with each purchase and use of materials (perpetual records).

Materials Requisition:

Prepared by the production manager when materials are needed.

Used to authorize material use for jobs.


💰 Materials Purchases & Use

Example:

Road Warriors purchased $2,750 of materials (direct + indirect) on March 4.

Journal Entry:

Posted to record the cost and application to jobs (based on requisition).


🧑‍🏭 Labor Cost Flows

Labor Time Ticket:

Document tracking the amount of time an employee spends on a job.

Direct Labor Posting:

Labor cost is posted to both job cost sheets and accounts.


🧮 Factory Overhead Accounting

(1) Set a Predetermined Overhead Rate (POHR)

Formula:

\text{POHR} = \frac{\text{Estimated Overhead Costs}}{\text{Estimated Activity Base}}

Example:

Road Warriors estimated:

Direct Labor: $125,000

Overhead: $200,000

POHR = 160% of direct labor cost.

(2) Apply Estimated Overhead to Jobs

Exercise Example:

Estimated overhead = $560,000

Estimated machine hours = 1,400

POHR = $400 per machine hour

Job 65A uses 13 hours → Overhead Applied = $5,200

(3) Record Actual Overhead Costs

Examples:

Indirect materials: $550

Indirect labor: $1,100

Other overhead (e.g., depreciation, rent, utilities): $5,270

Depreciation: $2,400

Rent: $1,620

Utilities: $250

Insurance: $1,000


📈 Accounting for Cost Flows

Period Costs:

Not part of manufacturing costs (e.g., administrative or selling expenses).

Journal Entries:

Entries record:

Material purchases and usage

Labor costs

Applied and actual overhead


📊 Financial Statements

📄 Schedule of Cost of Goods Manufactured (COGM)

Prepared monthly.

Summarizes total manufacturing costs.

Used to compute cost of goods completed and transferred.

📑 Income Statement

Includes:

Revenue

Cost of Goods Sold (COGS)

Gross profit

Period expenses

🧾 Balance Sheet

Reports inventory:

Raw Materials

Work in Process

Finished Goods (if applicable)


🧾 Closing Overhead Accounts

Factory Overhead T-Account

Applied Overhead is credited.

Actual Overhead is debited.

Over/Under Applied Overhead:

Overapplied: Applied > Actual → Credit Balance

Underapplied: Applied < Actual → Debit Balance

🧮 Adjustment Entry

Example:

Applied: $6,720

Actual: $6,920

Underapplied = $200 (debit balance) → Adjustment required


🧑‍💼 Job Order Costing in Service Companies

Applies to:

Advertising

Consulting

Legal services, etc.

Key Differences:

No raw materials or finished goods inventory.

Use Services in Process Inventory and Services Overhead.

Overhead applied using direct labor instead of physical goods.

Example:

Estimated Job Cost: $17,077

Price Quote (with markup):

17,077 \times 1.18 = 20,151

Gross Profit Ratio is calculated similarly to manufacturing.
