Job costing guide
How to measure job profitability accurately
Job costing compares the revenue earned from one project with the direct costs required to complete it. This provides a clear view of gross profit, margin, markup, and labor productivity.
Accurate job-cost records help contractors and service businesses identify profitable work, detect cost overruns, improve future estimates, and make better pricing decisions.
Use final invoices, time records, purchase receipts, subcontractor bills, equipment charges, and other reliable documentation whenever possible. Estimated costs can help during planning, but completed-job analysis should use actual figures.
Costs to include in job costing
Complete job costing requires more than labor and materials. Review every direct expense connected with delivering the work.
Material cost
Include parts, fixtures, supplies, consumables, delivery charges, waste, and every material purchased specifically for the job.
Equipment cost
Record rentals, equipment usage, fuel, transportation, setup, and other machine-related expenses attributable to the project.
Permits and inspections
Add permit fees, inspection charges, filing costs, licenses, and regulatory expenses required to complete the work.
Subcontractor cost
Include invoices and payments to licensed subcontractors, specialists, consultants, and outside service providers.
Other direct expenses
Capture disposal, parking, tolls, travel, temporary protection, cleanup, delivery, and any other job-specific expense.
Job cost and profit formulas
Labor cost is calculated from hours and loaded hourly cost:
Labor cost = labor hours × labor cost per hour
Total job cost combines labor with all other direct expenses:
Total job cost = labor + materials + equipment + permits + subcontractors + other expenses
Gross profit and gross margin are then calculated from the contract price before sales tax:
Gross profit = contract price − total job cost
Gross margin = gross profit ÷ contract price × 100
Markup compares gross profit with total job cost rather than revenue.

Common job-costing mistakes
Using the billing rate as labor cost
The customer billing rate includes overhead and profit. Job costing should use the actual loaded labor cost incurred by the business.
Ignoring small expenses
Fuel, disposal, delivery, parking, consumables, and similar expenses can materially reduce profit when repeated across many jobs.
Counting sales tax as revenue
Sales tax collected for a government authority is generally not operating revenue and should not increase calculated gross profit.
Reviewing only revenue
A high contract price does not guarantee a profitable job. Total cost, margin, markup, and labor productivity must also be reviewed.
Job Cost Calculator FAQs
What is job costing?
Job costing is the process of assigning revenue, labor, materials, equipment, subcontractors, permits, and other direct expenses to a specific project so the business can measure its actual profitability.
What should be included in total job cost?
Total job cost should include every direct expense required to complete the work, including loaded labor cost, materials, equipment, permits, subcontractors, delivery, disposal, travel, and other job-specific expenses.
What is the difference between margin and markup?
Gross margin measures profit as a percentage of revenue. Markup measures profit as a percentage of cost. The percentages are not interchangeable.
Should overhead be included in job costing?
This calculator focuses on direct job costs. Businesses should also use a consistent method to allocate overhead when evaluating fully burdened profitability and setting prices.
Why is sales tax excluded from gross profit?
Collected sales tax is normally held for remittance to a tax authority rather than retained as business revenue. Actual treatment depends on applicable accounting and tax rules.
How often should completed jobs be reviewed?
Completed jobs should be reviewed consistently, ideally as soon as reliable labor and expense data is available. Frequent review helps identify estimating errors, cost overruns, and pricing weaknesses.
