How to Calculate Job Profitability
By Trade Software USA Editorial · Published October 26, 2026 · Updated October 26, 2026
Quick answer
Job profitability starts with gross profit: revenue minus all job costs (materials, labor, subcontractors, and other direct costs). Express it as gross margin (profit ÷ revenue) to compare jobs fairly, and track it per job so you learn which kinds of work to pursue and which to stop bidding.
Key takeaways
- Gross profit = revenue − (materials + labor + subcontractors + other direct costs).
- Gross margin = gross profit ÷ revenue — use it to compare jobs of different sizes.
- Track margin per job type to learn which work actually pays.
- Labor is often underestimated — include payroll taxes and non-billable time.
Capture every job cost
Accurate profitability starts with complete costs. Materials and subcontractors are easy to remember; labor is where margin leaks. Include the fully loaded labor cost — wages plus payroll taxes and benefits — not just the hourly wage.
Gross profit vs. gross margin
Gross profit is a dollar figure; gross margin is a percentage. Margin lets you compare a $1,000 job and a $20,000 job on equal footing. A big job with a thin margin can be less valuable than a small job with a strong one.
Use it to make decisions
Track margin by job type, customer, and crew. Over a few months you'll see patterns: certain work consistently underperforms. That's your signal to reprice it or stop bidding it. Our Job Profit Margin Calculator shows gross profit, margin, and markup side by side for any job.
Frequently Asked Questions
Is gross margin the same as net profit?
No. Gross margin covers only direct job costs. Net profit also subtracts overhead (office, insurance, admin). A healthy gross margin must be large enough to cover overhead and still leave net profit.
What gross margin should I target?
There's no universal target — it varies by trade and business model. Rather than chase a benchmark, track your own margins and make sure they cover overhead with profit left over.
