Job Costing Template
Download a job costing template to compare estimated, committed, and actual construction costs by job, trade, cost code, and work package.
Track Project Costs Against the Original Budget
Job costing helps subcontractors understand how much a project is expected to cost, how much has been committed, what has already been spent, and whether the remaining budget is sufficient to complete the work. A structured job costing process makes it easier to identify cost overruns before they affect project margin.
This Job Costing Template is designed for subcontractors, specialty contractors, project managers, estimators, operations teams, and construction business owners. It provides a practical way to track labour, materials, equipment, subcontractors, purchase orders, expenses, change orders, billing, and forecast costs by project and cost code.
What Is Construction Job Costing?
Construction job costing is the process of assigning estimated, committed, and actual costs to a specific project. Costs are normally organised by cost code, trade, work package, project phase, location, or activity so the project team can compare performance against the approved budget.
A complete job cost report may include the original estimate, approved budget changes, purchase commitments, labour costs, material invoices, equipment costs, subcontractor charges, expenses, billed revenue, forecast costs, and projected profit.
When to Use This Template
- Setting the approved project budget after contract award
- Tracking committed and actual project costs
- Comparing estimated labour hours with hours used
- Monitoring material, equipment, and subcontractor spending
- Reviewing approved and pending change orders
- Forecasting the cost to complete each work package
- Preparing project cost reports for management review
- Analysing final project profitability after completion
Who Should Use This Template?
This template is suitable for subcontractors, specialty contractors, project managers, estimators, quantity surveyors, contract administrators, operations managers, finance teams, and business owners responsible for project financial control.
It can be adapted for electrical, plumbing, HVAC, roofing, concrete, steelwork, framing, drywall, painting, flooring, glazing, fire protection, demolition, excavation, landscaping, waterproofing, masonry, and other construction trades.
What a Job Costing Template Should Include
| Section | Purpose |
|---|---|
| Project Information | Records the project, client, contract value, project manager, start date, and current status. |
| Original Budget | Records the approved estimated cost for labour, materials, equipment, subcontractors, and other categories. |
| Budget Changes | Captures approved additions, omissions, transfers, and internal budget revisions. |
| Committed Costs | Tracks purchase orders, subcontracts, hire agreements, and other approved commitments. |
| Actual Costs | Records labour, supplier invoices, equipment, expenses, subcontractor charges, and other incurred costs. |
| Forecast to Complete | Estimates the remaining cost required to finish each cost code or work package. |
| Projected Final Cost | Combines actual costs with the forecast to complete. |
| Cost Variance | Compares the current budget with the projected final cost. |
| Revenue and Billing | Tracks original contract value, approved changes, invoiced revenue, and remaining billable value. |
| Margin Forecast | Calculates expected gross profit and gross margin based on current project performance. |
| Cost-Code Summary | Summarises financial performance by trade, activity, phase, location, or work package. |
| Notes and Forecast Commentary | Records causes of variance, risks, assumptions, corrective actions, and management decisions. |
How to Use the Template
- Enter the project details, original contract value, and approved budget.
- Set up cost codes that match the estimate and operational workflow.
- Allocate the original budget across labour, materials, equipment, subcontractors, and other direct costs.
- Enter approved budget changes and contract changes separately from the original values.
- Record committed costs from purchase orders, subcontracts, and equipment hire.
- Update actual costs from timesheets, supplier invoices, expenses, and project records.
- Estimate the remaining cost to complete each cost code.
- Review projected final cost, cost variance, billed revenue, and projected margin.
- Add notes explaining significant variances and required corrective actions.
- Update the workbook at a consistent weekly or monthly reporting interval.
An electrical subcontractor tracks a commercial fit-out using cost codes for containment, cable, distribution boards, lighting, labour, testing, and commissioning. The containment package is under budget, but labour hours for cable installation are higher than planned because of restricted access and sequencing delays. The project manager updates the forecast to complete, records the reason for the variance, and reviews whether approved change-order work can recover part of the additional cost.
Best Practices for Construction Job Costing
- Use the same cost codes from estimate through project completion.
- Separate original budget, approved changes, commitments, actual costs, and forecasts.
- Update labour hours and cost frequently.
- Record purchase commitments before supplier invoices arrive.
- Review pending change orders separately from approved revenue.
- Forecast the remaining cost instead of relying only on costs already incurred.
- Investigate large cost or labour variances promptly.
- Reconcile workbook totals with financial records at each reporting period.
- Document the reason for budget transfers and revisions.
- Preserve the original estimate and approved project baseline.
Common Job Costing Mistakes
- Using different cost codes in estimating and project delivery
- Tracking actual costs without recording commitments
- Including pending change orders as approved revenue
- Failing to update cost-to-complete forecasts
- Recording supplier invoices against the wrong project or cost code
- Ignoring labour productivity until the project is nearly complete
- Combining budget revisions with original budget values
- Using gross margin and markup interchangeably
- Relying on invoiced revenue instead of earned or approved contract value
- Waiting until project closeout to review profitability
Frequently Asked Questions
What is the difference between a budget, commitment, and actual cost?
The budget is the planned amount available for the work. A commitment is an approved obligation, such as a purchase order or subcontract, that may not yet have been invoiced. An actual cost is a cost already incurred or recorded.
What is cost to complete?
Cost to complete is the estimated remaining cost required to finish a cost code, work package, or project. It should reflect current progress, productivity, open purchase commitments, programme conditions, and known risks.
How is projected final cost calculated?
Projected final cost is normally calculated by adding actual cost to the forecast cost to complete. Some businesses also compare this result with open commitments to ensure the forecast is not understated.
How often should job costs be updated?
Update them often enough to support timely decisions. Weekly updates are useful for labour-intensive work, while a formal monthly review can support financial reporting and project forecasting.
Should pending change orders be included in projected revenue?
Pending changes should be tracked separately from approved contract value. They may be shown as potential revenue, but they should not be treated as approved until the customer or contractor has formally authorised them.
Can this template compare estimated and actual labour hours?
Yes. Labour hours can be tracked by cost code, crew, activity, phase, or work package so the project team can compare estimated productivity with actual performance.
Use Current Cost Data to Protect Project Margin
A reliable job costing process gives subcontractors visibility into where project funds are being spent, which work packages are performing well, and where corrective action may be needed. Tracking budget, commitments, actual costs, forecasts, and revenue in one structure supports better project decisions.
An XLSX workbook provides a practical starting point for project cost control. As operations grow, SimplySub can help subcontractors organise estimates, jobs, purchase orders, expenses, change orders, invoices, labour records, documents, and job-cost information.
