Why both numbers matter—and why watching only one will mislead you.
Gross margin and net margin measure profitability at two different points on the P&L. In GovCon professional services, the distinction is more consequential than in most industries because of the indirect rate structure sitting between the two.
Gross margin is what you keep after paying the direct costs of performing the work—primarily direct labor and subcontractor costs. It's the profit on the contract itself, before the company's operating infrastructure takes its share.
Net margin is what the business keeps after everything—fringe, overhead, G&A, interest, and taxes.
| Gross Margin | Net Margin | |
|---|---|---|
| Revenue | ✓ | ✓ |
| Direct labor | Deducted | Deducted |
| Subcontractor costs | Deducted | Deducted |
| Other direct costs (ODCs) | Deducted | Deducted |
| Fringe | — | Deducted |
| Overhead | — | Deducted |
| G&A | — | Deducted |
| Interest & taxes | — | Deducted |
| What it tells you | How the contract was bid and is being run | What the business is bringing home |
In a typical commercial business, gross margin and net margin move in the same direction. Costs go up, both margins go down. In GovCon, they can move in opposite directions—and that's where people get confused.
A PM can run a contract perfectly, hit every staffing target, keep direct costs in line, and still see the contract's net margin deteriorate—because the company lost a major contract elsewhere, and the indirect rate pools redistributed over a smaller direct labor base. Fringe, overhead, and G&A all went up as a percentage, and the PM had nothing to do with it.
The reverse happens too. A contract with mediocre gross margins can look fine on a net basis when indirect rates are low—masking the fact that the contract was bid too thin and will become a problem the moment rates move.
PMs and Division Leads control direct costs—who's staffed, at what rates, how efficiently the work is performed. They don't control fringe, overhead, or G&A. Gross margin is the metric that reflects their decisions and their performance. If a PM's gross margins are strong but net is weak, the problem isn't on the contract—it's in the company's indirect structure, and that's the CFO's domain.
The gap between gross margin and net margin is your indirect rate structure in action. If that gap is widening, your rates are climbing—either because indirect spending is up or because the direct labor base is shrinking. If the gap is narrowing, your rates are getting more efficient. Watching only net margin hides whether the improvement came from better contract execution or from lower indirect rates.
When you price a contract, gross margin tells you whether the bid is competitive and executable. Net margin tells you whether the contract contributes to the company's bottom line at your current wrap rate. A contract can have a strong gross margin and still lose money on a net basis if your wrap rate is too high—which means the problem isn't the bid, it's the rate structure.
In practice, GovCon executives tend to fall into one of two camps.
Camp 1: "Net margin is all that matters." These are typically companies with heavy cost-plus portfolios. On a cost-plus contract, gross margin is structurally defined by the fee—you're not negotiating the spread, you're managing your indirect rates to maximize the fee pool. Net margin becomes the primary focus because that's where the levers are.
Camp 2: "Gross margin is all that matters." These are typically companies with heavy FFP or T&M portfolios. On firm-fixed-price work, every dollar of gross profit is a dollar you fought for in the bid and preserved through execution. Indirect costs matter, but they're a P&L function managed centrally—the contract-level fight is about gross profit.
Both camps are right about their own contract types, and both are wrong if they ignore the other metric. A company with 90% cost-plus work that ignores gross margin will struggle when it tries to win FFP work. A company with 90% FFP work that ignores net margin may not realize its indirect rates are eating the profits its PMs are generating.
There's a deeper problem with the net-margin-only mindset that goes beyond missing a metric. In a cost-plus environment, the indirect rate structure can create incentives that are actively harmful to the business.
If your actual indirect rates are running higher than your provisional rates, you may be tempted to hire more direct labor to grow the base those rates are applied to—bringing the rates down by spreading the same indirect costs over more labor dollars. Revenue goes up, rates come down, and the math looks better. But you've added headcount to fix an accounting problem, not because the work demanded it.
The reverse is equally dangerous. If your actual rates are running below your provisionals, you're collecting more in indirect reimbursement than you're spending—which means at year-end, you'll owe money back to the government. The temptation is to increase indirect spending to get actuals in line with provisionals so you don't have to write that check.
Both behaviors are rational within the cost-plus framework. And both are extremely dangerous habits to carry into an FFP or T&M environment, where there's no government reimbursement mechanism to absorb the extra spend. A company that grew up managing to its rates rather than managing to its margins will struggle the moment its contract mix shifts—and in today's GovCon market, every company's mix is shifting.
Gross margin is also the metric that reveals the true economics of subcontracting. Two contracts can have identical net margins, but if one is 80% subcontracted and the other is 80% direct labor, the gross profit dollars are dramatically different.
A $10M contract at 8% net margin generates $800K either way. But if $8M of that is subcontracted at a 7% markup, your gross profit on the sub work is roughly $523K—and $523K of that $800K net came from pass-through work that doesn't build your team, develop your capabilities, or invest in your infrastructure. The other $2M of direct labor at 45% gross margin generated $900K in gross profit—that's the work that builds the business.
Net margin treats both dollars the same. Gross margin shows you where the value is actually being created.
The Operator's View
I'm grateful for having started my career in GovCon through investment banking and private equity before pivoting to operations. One of the most valuable things it taught me was watching how CXOs think about budgeting and projections—and the blind spots that come with it.
Everyone I worked with fell into one of two camps: you either focused on contract net margin and never looked at gross margin, or you understood gross margins and dismissed net margins as irrelevant. You could predict which camp someone was in by looking at their contract mix. Heavy cost-plus? Net margin camp. Heavy FFP? Gross margin camp.
Both extremes are dangerous if you want to be a well-rounded operator.
When we work with PMs and Division Leads, we want them focused on managing their gross profit numbers—because that's what they control. They don't set the fringe rate. They don't decide how much the company spends on G&A. Those are indirect cost pool decisions that happen above their pay grade. But we also want them to be cognizant of the net margin, because it helps them understand how we bid and operate the contract within the constraints of our current wrap rate.
Net margin dictates what the business is bringing home. Gross margin indicates whether the contract was bid correctly and is being run correctly. If your indirect rates have ballooned due to heavy spending or a material contract loss, it's entirely possible that a PM or Division Lead had absolutely nothing to do with it. Why hold them accountable when their margins are good but the net is bad? That's the CXO's domain to figure out.
The answer isn't to pick a metric. It's to know which one to look at depending on what question you're trying to answer—and to recognize that the gap between them is telling you something important about your cost structure every single month.
