Calculate total job cost by summing direct materials, direct labor, and applied overhead for a specific manufacturing job or work order.
Job costing, or job order costing, tracks costs for individual jobs, batches, or work orders. Unlike process costing which averages costs over large volumes of identical products, job costing assigns specific materials, labor hours, and overhead to each unique job. This makes it the go-to costing method for custom manufacturers, job shops, print shops, construction projects, and any operation where each order differs from the next.
The job cost sheet is the central document, accumulating direct materials issued to the job, direct labor hours charged at their respective rates, and manufacturing overhead applied using a predetermined overhead rate. The sum of these three cost pools equals the total job cost, which can then be divided by units produced for a per-unit cost.
This calculator helps estimators, project managers, and cost accountants quickly compute the total cost and per-unit cost for any manufacturing job. Enter the materials, labor, and overhead details, and get an instant job cost summary.
Job costing ensures every custom order is priced to cover its actual costs and generate margin. Without accurate job costs, you risk underbidding profitable work or overbidding and losing contracts. This calculator gives you a fast, reliable way to estimate or verify job costs before quoting or after completion. Having accurate figures readily available streamlines reporting, audit preparation, and strategic planning discussions with management and key stakeholders across the business.
Job Cost = Direct Materials + Direct Labor + Applied Overhead Direct Labor Cost = Labor Hours × Labor Rate Applied Overhead = Labor Hours × Overhead Rate (or Machine Hours × OH Rate) Cost per Unit = Total Job Cost ÷ Units Produced
Result: $23,700 total / $47.40 per unit
Direct materials = $8,500. Direct labor = 120 hours × $35 = $4,200. Applied overhead = 120 hours × $25 = $3,000. Total job cost = $8,500 + $4,200 + $3,000 = $15,700. Wait — let me recalculate: $8,500 + $4,200 + $3,000 = $15,700. Cost per unit = $15,700 ÷ 500 = $31.40.
Every job in a job costing system has a cost sheet — physical or digital — that serves as the repository for all costs charged to that job. It typically includes the job number, customer name, description, start and end dates, and three cost sections: direct materials (with requisition references), direct labor (with time ticket details), and applied overhead.
Because actual overhead is not known until period-end, manufacturers use a predetermined rate calculated at the start of the year. The formula is: Estimated Total Overhead ÷ Estimated Total Activity Base (labor hours, machine hours, etc.). This rate is applied to each job as work progresses, providing timely cost information for pricing and control.
Modern ERP systems automate job costing by linking material issues, time entries, and overhead rates to work orders in real time. This eliminates manual tracking errors and provides instant job cost visibility. Managers can monitor jobs in progress, compare actual to estimated costs, and take corrective action before a job becomes unprofitable.
Job costing is a cost accounting method that traces costs to individual jobs or work orders. Each job has its own cost sheet that accumulates direct materials, direct labor, and applied overhead. It is used when products are custom or produced in distinct batches.
Use job costing when each order is unique or distinct — custom manufacturing, printing, construction. Use process costing when producing large volumes of identical products — chemicals, food processing, oil refining. Some operations use hybrid systems combining elements of both.
Overhead is applied using a predetermined rate, typically calculated as total estimated overhead divided by total estimated labor hours or machine hours. Each job then receives overhead based on how many hours it consumes. This distributes indirect costs fairly across jobs.
The difference between quoted price and actual job cost is a cost overrun. Tracking overruns by cause — material waste, extra labor, scope changes — helps improve future estimates. Some contracts include change-order provisions that allow requoting when scope changes.
Yes. Professional services firms, agencies, and repair shops commonly use job costing. Instead of materials, they may track costs like subcontractor fees, travel, and software licenses. Labor is typically the largest component for service jobs.
Jobs in progress at period-end remain in Work-in-Process (WIP) inventory. Costs accumulated so far stay on the job cost sheet. Only when the job is completed does the cost transfer to Finished Goods or Cost of Goods Sold.
