JOB PROFIT

JOB COSTING VS REAL JOB PROFIT.

QUICK ANSWER

Job costing tracks what you spent. Real job profit is what you earned once overhead allocation, WIP accuracy, and billing timing are applied. Most subcontractors think they have both. They usually only have the first one, and the distance between the two is where the profit disappears.

There are two profit numbers on every job, and job costing only produces the input to one of them. Gross profit comes out of the cost report. Net profit takes one more step, because overhead has to be charged against the job before you know whether the work paid for the business behind it. Most subcontractors stop at gross, call the job good, and then wonder why the bank balance doesn't agree with the P&L. The report was never wrong. It was answering a different question than the one being asked.

THE DEFINITION

WHAT IT MEANS.

Real job profit is what you earned on a job after overhead allocation, WIP accuracy, and billing timing are applied to what job costing says you spent.

The published figures come from two places. CFMA's 2024 Construction Financial Benchmarker reports 21.8 percent gross profit margin, 11.8 percent SG&A and 6.3 percent net income before taxes across all respondents, with the best-in-class top quartile at 11.9 percent before taxes, and Jones Maresca and Company's 2025 Performance Benchmarks put specialty contractor gross margin at 15 to 25 percent with total indirect cost at 8 to 15 percent. Every one of those describes the market rather than a number we hold jobs to. The number to hold a job to is the one for your trade at your revenue, which is on /construction-subcontractor-financial-benchmarks-by-trade, with SPM's own floor of 10 percent net profit before taxes underneath it. A job that clears the gross figure and misses the net one is telling you the overhead rate is the problem rather than the field. That is a pricing conversation.

WHAT WE SEE IN THIS BUSINESS

WHERE THE PROFIT DISAPPEARS.

01

Overhead isn't in the job cost

Job costing tracks direct costs. Your office, your staff, your software, your insurance, and your owner salary get allocated at the company level and not at the job level. If you read a job costing report without applying your overhead rate, you're looking at gross margin and calling it net profit. The difference is your overhead rate multiplied by the job's revenue, and on most jobs that's a double digit number.

02

Billing timing creates false margin

A job that's 40 percent billed and 30 percent complete shows revenue without the costs to match it. The job costing report reads strong because revenue is ahead of cost. That margin isn't earned yet. When the costs catch up in the next billing cycle the number reverts, so reading job costing at a billing ahead point overstates the margin until the job normalizes.

03

Unbilled change orders add cost without revenue

A $40K change order gets approved and the crew starts. The cost codes to the job immediately and the billing event hasn't happened. Job costing shows the cost with no revenue against it. Every week that change order stays unbilled, the job's apparent margin drops. The billing hasn't caught up to the cost.

04

The wrong overhead rate in the estimate

You estimated this job at 11 percent overhead. Your true overhead rate is 16 percent, because you added two PMs and a project coordinator since the estimate was built. The job costing report knows what you spent on direct costs and it doesn't know your overhead rate moved. The distance between the estimated overhead rate and the true one is pure profit erosion on every job priced with the old number.

THE MATH

WHAT IT LOOKS LIKE IN DOLLARS.

A $1M job, both ways

Contract revenue of $1,000,000 less direct job costs of $780,000 gives gross profit of $220,000, or 22 percent. Now allocate overhead of $110,000. Net job profit is $110,000, or 11 percent. The job costing report stops at the first number, and the second one is the one that funds the business.

What it looked like on a real set of books

A $4.9M concrete sub was netting $161K on $4.9M of revenue, which is 3.3 percent. The job costing existed and nobody was applying an overhead rate to it. Once job costing was tied to real job profit with the overhead rate applied and the WIP cleaned up, net profit went to $1.1M.

HOW SPM FIXES IT

THE FOUR THINGS THAT HAVE TO WORK.

Job costing with all seven cost categories coded accurately

Material, labor, equipment, subcontractors, and the rest each get their own code, and every dollar goes to the code it belongs to. When the categories get blended, the report still balances and it stops being usable for pricing the next job. Clean coding is the input that everything downstream depends on.

An overhead rate verified against your true costs

The rate gets built from what you're spending now and not from last year's tax return, and it gets applied to every job so gross profit turns into net profit on the same report. For scale, Jones Maresca and Company's 2025 Performance Benchmarks put total indirect cost at 8 to 15 percent of revenue across construction and CFMA reports SG&A at 11.8 percent across all respondents, and neither of those is a target we set for you. /construction-overhead-rates-by-trade holds the rate for your trade and band. When the verified rate comes back at 16 percent, every estimate built at 11 percent was underpriced by 5 points.

Billing that matches completed work so the WIP is clean

Billing ahead of the work creates margin that's not earned, and billing behind the work leaves margin you already made out of view. Either way the job report misleads you until the two line up. We reconcile the billing against percent complete every month, so the margin you read is the margin you have.

A cost to complete that reflects what's left

The schedule tells you what should be left. The crew tells you what's really left. A cost to complete built from the second one is what makes the job profit number reliable, and it's the piece most subcontractors skip because nobody owns it.

COMMON QUESTIONS

FREQUENTLY ASKED.

Job costing tracks what you spent on a specific project by cost category. Real job profit is what you earned on that project after overhead allocation, billing timing, and WIP accuracy are applied. Job costing is an input and job profit is the output. You can have good job costing and still not know your real job profit if the overhead rate is wrong or the billing timing isn't captured correctly.

Job costing shows direct costs: material, labor, equipment, and subcontractors. It doesn't include overhead allocation, which can change job profit by 10 to 15 percentage points. It also doesn't account for billing timing, so a job can read strong on direct cost margin while it has a large underbilling that hasn't been collected.

Gross profit is revenue minus direct job costs, meaning the seven cost categories. Net profit is gross profit minus overhead. A job can read 22 percent gross profit and 8 percent net profit if overhead is 14 percent. The gross profit number comes out of job costing, and the net profit number requires knowing your overhead rate.

Real job profit requires four things working correctly: job costing with all seven cost categories coded accurately, an overhead rate verified against your true costs, billing that matches completed work so the WIP is clean, and a cost to complete that reflects what's left rather than what the schedule says. When all four are working, the job profit number is reliable.

Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Strategic is where every job shows its margin while it is still open: a bookkeeper we choose does the books and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. Platinum is where you approve and the money side gets handled: a controller we choose handles your bills and receivables the way an in-house controller would, and you approve every payment. No payroll. No scope gaps.
