Formula Used
| Metric | Formula |
|---|---|
| Direct Labor Cost | Labor Hours × Labor Rate |
| Material Wastage Cost | Direct Material Cost × Wastage % |
| Adjusted Material Cost | Direct Material Cost + Material Wastage Cost |
| Prime Cost | Adjusted Material Cost + Direct Labor Cost |
| Variable Overhead | Overhead Base × Rate, or Overhead Base × Rate % for cost-based methods |
| Total Factory Overhead | Variable Overhead + Fixed Overhead |
| Manufacturing Cost | Materials + Labor + Overhead + Setup + Subcontract + Freight + Other Direct Costs |
| Selling and Admin Allocation | Manufacturing Cost × Selling and Admin % |
| Contingency Reserve | Manufacturing Cost × Contingency % |
| Total Job Cost | Manufacturing Cost + Selling and Admin Allocation + Contingency Reserve |
| Cost Per Unit | Total Job Cost ÷ Units Completed |
| Recommended Bid | Total Job Cost × (1 + Markup %) |
| Quoted Profit | Quoted Price − Total Job Cost |
| Quoted Margin % | (Quoted Profit ÷ Quoted Price) × 100 |
| Invoice Total | Recommended Bid + Tax Amount |
Cost-based overhead methods treat the rate as a percentage. Hour, machine, and unit methods treat the rate as currency per selected base.

Example Data Table
| Job | Units | Materials | Labor Hours | Labor Rate | Basis | Rate | Total Cost |
|---|---|---|---|---|---|---|---|
| Office Renovation | 12 | 18,000.00 | 240 | 28.00 | Labor Hours | 18.00 | 38,129.58 |
| Custom Cabinets | 25 | 9,500.00 | 120 | 24.00 | Prime Cost % | 22.00 | 18,460.94 |

These figures are illustrative. Your actual results change with overhead policy, wastage, markup, and support cost allocations.
Frequently Asked Questions
1. What is job costing in accounting?
Job costing tracks all costs assigned to a specific project, order, or customer engagement. It helps you measure actual spending, compare estimates, and decide whether pricing and margins remain acceptable.
2. Which overhead basis should I choose?
Choose the basis that best reflects resource consumption. Labor hours work for labor-heavy jobs. Machine hours suit equipment-driven work. Cost-based percentages fit environments where support costs scale with labor, materials, or prime cost.
3. Why include wastage in material costing?
Wastage captures scrap, spoilage, damage, and unavoidable loss. Including it prevents underpricing and produces a more realistic material burden for estimating, control, and profitability reviews.
4. Is markup the same as margin?
No. Markup is added on top of cost. Margin measures profit as a share of selling price. A 20% markup does not equal a 20% margin, so reviewing both is useful.
5. Should selling and administrative costs be allocated?
Many firms allocate them when they want a fuller view of job profitability. For internal production control, some teams analyze manufacturing cost separately and then layer nonmanufacturing allocations afterward.
6. What does the quoted profit result show?
It shows the profit or loss based on your entered quoted price. A negative figure suggests the quote may not recover full assigned cost under the assumptions used.
7. Can this calculator support bid preparation?
Yes. It estimates total cost, cost per unit, markup-based bid value, and invoice total with tax. That makes it useful for preparing quotes and checking whether a proposed selling price is reasonable.
8. Why export the results to CSV or PDF?
CSV works well for analysis, spreadsheet imports, and audit trails. PDF is better for sharing a clean result snapshot with managers, clients, or project files.
