I have spent the last three years rebuilding the operating-KPI file at private marketing agencies and consulting firms in the 20-to-300 FTE band, and every engagement eventually lands on the same question: what is "normal"? In 2026 the answer is no longer just the agency-ops industry surveys. The listed agency holdcos and consulting majors disclose enough quarterly detail in their 10-Qs to build a defensible public-cohort benchmark — operating margin, revenue per employee, organic growth, the seasonal pattern across the year. Omnicom and Interpublic closed their merger Q4 2025; Accenture is at 13.8% op margin with 800,000 staff; Huron and FTI run 8–12%; Stagwell is the only growth story at +8% organic. Here is the working read on what those numbers mean for private firms thinking about utilization, rev-per-FTE, and operating margin.
01 Why the listed cohort matters for private benchmarking
Most agency and consulting benchmarks I see in the wild come from membership surveys — Parakeeto, Productive.io, the SoDA report, the SCPI consulting benchmark. They are useful for utilization-band ranges and for fee structure norms, but they are anonymised, self-reported, and skew toward the firms willing to fill out the survey. The listed-peer cohort is different. Every number is audited, filed under penalty of perjury, reconciled to GAAP, and disclosed on a regular quarterly cadence. The numbers reflect the firms private agencies and consulting shops will eventually compete against for talent, for clients, and — for the ones planning an exit — for buyer attention.
The cohort breaks into three sub-groups. The advertising holding companies — Omnicom (OMC, post-Interpublic merger), Stagwell (STGW), with WPP and Publicis as European 20-F filers — collectively employ around 200,000 people and represent the upper end of the agency operating model. The global consulting major — Accenture (ACN) at ~800,000 employees — is the structural ceiling of how big a services firm can scale with the offshore-delivery model. The mid-cap US consulting names — Huron Consulting (HURN), FTI Consulting (FCN) — at $1.7–3.8B revenue are the cleanest comps for the larger end of private mid-market consulting firms. Each group sets a different benchmark for what private firms should target.
The listed numbers are the only audited benchmark in the space. Use them as the floor for what a healthy private firm should be doing — not the ceiling.
The headline operating reality for Q1 2026: Accenture leads the cohort at 13.8% operating margin in its Q2 fiscal-2026 quarter (period ended February 2026), with the combined Omnicom-Interpublic entity at 10.4% in its first post-merger quarter. Huron and FTI Consulting sit at 8.1% and 8.5% respectively on Q1 2026 GAAP — Q1 is structurally the weakest quarter for the cohort, with both names running 10–12% on a trailing-twelve-month basis. Stagwell reports 1.4% GAAP operating margin in Q1 2026, distorted heavily by amortization of acquired-intangibles from the Doner, MMI, and Locaria acquisitions of recent years; on an adjusted-EBITDA basis Stagwell guides 16–17%, but the GAAP figure is the apples-to-apples read against private owner-operator firms.
02 Revenue per employee — the most useful single benchmark
Revenue per employee is the cleanest single metric I use when comparing a private agency or consulting firm to the listed cohort, and the only metric that can be calculated without disclosure of utilization, realization, or rate-card data. Take the trailing-twelve-months revenue, divide by the headcount disclosed in the most recent 10-K or proxy statement, and you have a number that tells you whether the firm is generating the kind of billable productivity that puts it in the same operating envelope as the public market.
The bottom of the cohort is Accenture at $91K — and that number is the single most misleading data point in the listed cohort if you do not understand the operating model. ACN has roughly 800,000 employees globally, with the majority of delivery staff in India, the Philippines, and other offshore locations. The blended cost-of-services rate per employee is a fraction of US onshore. For a private US-onshore consulting firm or marketing agency, the relevant benchmarks are Huron at $277K (healthcare-and-education advisory, almost entirely US-staffed) and FTI Consulting at $478K (forensic, litigation, restructuring — premium billable rate work). The practical band for a healthy US-onshore mid-market consulting firm is **$300–450K of revenue per FTE**. Below $250K signals utilization or realization problems; above $500K is unusual without a very specific premium-niche positioning.
The combined Omnicom-Interpublic entity sits at roughly $181K per employee on the Q1 2026 annualized run-rate, down from the standalone OMC of ~$198K because the merger blended in IPG's lower rev/employee. The marketing services range is structurally lower than consulting because the agency operating model includes media-management and creative-production staff who have lower individual billable productivity than partner-track consultants. The right private-agency target is **$150–250K per FTE** for a healthy US-onshore mid-market shop running 60–65% billable utilization at the agency-wide level.
Stagwell is the interesting outlier at $217K — the highest in the agency cohort, reflecting both the more aggressive Q1 2026 organic growth (+8% reported) and Stagwell's strategy of running leaner agency-of-record teams with more freelance/contract delivery than the traditional holdco model. The takeaway: revenue per employee is the metric that responds most quickly to operating-discipline changes. Private firms can move this number up by 10–15% inside 12 months by tightening the production-headcount-to-billable-headcount ratio and shifting a portion of overflow capacity to qualified freelance rather than FTE.
03 Operating margin — what is achievable at scale
The operating-margin question is the one most private agency and consulting principals ask first when looking at a peer benchmark, and it is also the one most likely to be misread. The listed cohort sits at GAAP operating margins between 1% (Stagwell, distorted by amortization) and 15% (Accenture in its seasonally-strongest quarter). The right way to read those numbers depends entirely on what the private firm is solving for — sale-process EBITDA, cash margin for owner distribution, or operating-discipline benchmark for the management team.
The Accenture ceiling — 13–15%
Accenture's 13.8% Q2 FY26 operating margin (Q1 FY26 ran at 15.3% — Q1 is structurally strongest in ACN's fiscal year because year-end client spend pulls forward) represents the structural ceiling of what a global staffing-heavy services business can achieve at scale. The 13–15% range is supported by global delivery cost arbitrage, technology-driven productivity, and rate discipline at the partner level. For private firms, 13% should be considered the operating-margin ceiling on a fully-loaded basis (after owner replacement compensation at market rates) — exceeding it on a sustained basis is rare without either niche premium pricing or significant offshore-staffing leverage.
The mid-cap consulting band — 8–12%
Huron and FTI Consulting run between 8% and 12% across the quarterly cycle — Q1 is the weakest quarter for both (8.1% and 8.5% respectively in Q1 2026), Q3 the strongest (11.3% HURN, 12.3% FCN). Trailing-twelve-month operating margin sits at ~10% for both names. This is the practical benchmark band for $20–100M private consulting firms with onshore US delivery, mid-tier billable rates ($300–500/hr blended), and 70–75% billable utilization for delivery staff. Sustained 10% GAAP operating margin (or 12–14% on an EBITDA basis adding back amortization and owner-replacement adjustments) is the right target for a healthy private mid-market consulting firm.
The agency holdco band — 10–13%
The Omnicom + Interpublic combined entity at 10.4% Q1 2026 sits at the lower end of historical ad-holdco operating-margin disclosures; the standalone OMC pre-merger ran 12–13% across 2024–2025. The compression from the merger reflects merger-integration costs and the dilution of OMC's structurally-higher margin into IPG's structurally-lower margin (IPG ran 10–11% in healthy quarters before the deal closed). For private creative and marketing agencies, the practical operating-margin benchmark is **10–15% on a fully-loaded basis** at the $5–50M revenue band, with the upper end achievable for tightly-positioned specialist shops and the lower end the floor for a healthy generalist creative or media agency.
Stagwell's 1% GAAP margin does not mean Stagwell is unprofitable — it means the public-market roll-up model creates GAAP distortion that private owner-operators do not face. Read the adjusted EBITDA carefully but do not benchmark to it.
Stagwell is the cautionary read. The 1.4% Q1 2026 GAAP operating margin reflects $44.3M of D&A in the quarter — primarily amortization of acquired intangibles from a long history of agency acquisitions (the company has roll-up at the centre of its strategy). Stripping out the D&A and adding back stock-based compensation, the adjusted EBITDA margin runs at 16–17% per company guidance. The lesson for private firms: the only operating-margin benchmark that translates cleanly from listed to private is GAAP operating margin for firms without acquired-intangibles amortization in the mix. Most owner-operator private firms do not have material amortization, so the GAAP comparison to OMC, HURN, FCN, and ACN is the apples-to-apples read.
04 Quarterly seasonality — the pattern most private firms ignore
The single most actionable insight from the listed cohort is the quarterly seasonal pattern of operating margin. Across every name in the cohort, Q1 is the weakest quarter and Q3 is the strongest, with Q2 and Q4 in between. The pattern is consistent enough across six quarters of data that any private firm running level monthly operating reviews without adjusting for seasonality is mis-reading their own performance.
Look at the listed numbers across the six quarters from Q4 2024 to Q1 2026. Accenture's Q1 (their Q2 fiscal): 13.8% Q2 FY26, 12.5% Q2 FY25. Accenture's Q3 (their Q4 fiscal): 14.5% Q3 2025. Huron: 8.1% in both Q1 2026 and Q1 2025; 11.3% in Q3 2025. FTI Consulting: 8.5% Q1 2026, 8.8% Q1 2025; 12.3% Q3 2025. Omnicom standalone (Q1 25): 12.3%; Q3 25: 13.1%. The pattern is not subtle — across the cohort, Q1 operating margin runs **3–4 percentage points below** the Q3 peak.
The seasonal driver is straightforward: client budgets reset in Q1, project starts cluster in Q1 with full-quarter staff cost but partial-quarter revenue recognition (especially in consulting where retainers ramp in over 4-8 weeks), and Q1 also carries the full weight of annual compensation increases and benefit-cost resets that flow through cost-of-services. By Q3, the same client engagements are running at full revenue recognition with the staffing cost already absorbed, and operating leverage shows up cleanly in the margin. For private firms, the implication is that a 4-percentage-point operating margin swing between Q1 and Q3 is normal — not a signal of operating distress in Q1 or operating excellence in Q3.
The practical implication for private firms running an exit-prep calendar: timing the start of a sale process matters. A buyer reviewing trailing-three-month financials in Q2 will see the Q1 weakest-quarter operating margin. A buyer reviewing trailing-three-month financials in Q4 will see the Q3 strongest-quarter operating margin. The difference of 3–4 percentage points of operating margin on a $20M revenue firm is $600K–$800K of EBITDA, and at a 7x multiple that is $4M–$6M of headline valuation difference attributable to nothing but process timing. Open the marketing for a process in early-Q4 so the trailing financials buyers diligence cover the Q3 peak; close in Q1 or early-Q2 so the working-capital normalisation cycle runs over the seller's books rather than the buyer's.
05 The wage environment underneath the margin
No agency or consulting margin benchmark holds up without naming the wage environment that determines what cost-of-services looks like at the firm level. The BLS production-worker hourly earnings series for advertising-and-PR (CES6055000003) and management-and-technical-consulting (CES6054160003) provide the cleanest read on what the listed cohort and private firms are paying their billable staff in 2026.
Advertising and PR hourly earnings: $52.47 in March 2026, up from $44.59 in March 2022 — a cumulative **+17.7% increase** over four years. The year-over-year trajectory ran hottest in 2024–2025 at +4.6% and +7.2% respectively before moderating to +3.9% in Q1 2026. Management and technical consulting: $51.58 in March 2026, up from $45.60 in March 2022 — cumulative **+13.1%**. Consulting wages front-loaded in 2023 at +6.4% YoY then moderated to +1.9% by Q1 2026. The two industries have followed different wage curves over the four-year period but ended in roughly the same hourly-earnings band.
The implication for private firms is the line-item math on operating margin. A $30M agency with 150 production-staff FTEs earning a blended $50/hr has roughly $15.6M of fully-loaded labor cost per year — 52% of revenue. A 17.7% cumulative wage increase over four years adds roughly **$2.75M to that labor line** without any change in headcount or productivity. Recapturing that compression requires either a comparable rate-card increase, a 4–5 percentage point gain in billable utilization, or some combination of the two. Private firms that have held rate cards flat since 2022 and have not gained utilization are running 8–9 percentage points lower operating margin than they would be at unchanged wage costs — which is roughly the difference between the Accenture 13% ceiling and the mid-cap consulting 4–5% floor for an under-priced firm.
Productivity is the offsetting force. The FRED nonfarm productivity series (OPHNFB) showed +2.92% YoY in Q1 2026, materially above the long-run 1.5% trend and consistent with the broader narrative of AI-driven productivity gains landing in services-sector workflows during 2025–2026. The listed cohort's revenue-per-employee numbers have held flat to up YoY, suggesting the productivity gains are being captured rather than competed away. Private firms should target +3–5% revenue per employee growth in 2026 as the baseline expectation if AI integration is real. Anything below +3% suggests the productivity gain is leaking out through lower realisation rates rather than being captured in the operating line.
06 What private firms should benchmark to — by FTE band
The listed cohort gives a defensible upper and lower bound for what a healthy private firm should be doing. Translating those bounds into target ranges by FTE band and firm type is where most of the operating-KPI rebuild work lands. Here is the working framework I use for $5–50M private firms in 2026.
Creative / marketing agencies, 20–80 FTE
Revenue per FTE target: **$150–220K**. Operating margin target (fully-loaded, post-owner-comp): **10–14%**. Billable utilization target at the production-staff level: 75–80%; agency-wide annual net utilization 55–62%. The Omnicom standalone (pre-IPG merger) operating profile is the closest public reference — $200K rev/FTE, 12–13% op margin, run lean by historic holdco standards. Stagwell is closer in headcount density to the upper end of this band but skews higher rev/FTE because of the leaner agency-of-record model.
Creative / marketing agencies, 80–300 FTE
Revenue per FTE target: **$170–250K**. Operating margin target: **11–15%**. Utilization targets unchanged. At this scale, agency-wide ops infrastructure (PSA, finance, dedicated HR/talent) starts to absorb a 1-2 percentage point fixed cost that lower-scale shops do not carry — but the larger book of business and the diversification across client cohorts supports better realization and lower CAC. The combined Omnicom-Interpublic at $181K/FTE and 10% margin is the floor reference; STGW at $217K is the upper-quartile reference.
Consulting firms, 20–80 FTE
Revenue per FTE target: **$280–400K** for US-onshore boutique consulting (strategy, ops, financial, technology). Operating margin target: **10–14%** GAAP. Billable utilization at the consultant level: 70–75% target; firm-wide annual net 55–62%. Huron Consulting at $277K/FTE and 10% TTM op margin is the closest mid-cap public reference. The FTI Consulting profile at $478K/FTE is reachable for niche advisory practices (forensic, restructuring, litigation support) but unusual for general management consulting.
Consulting firms, 80–300 FTE
Revenue per FTE target: **$300–450K**. Operating margin target: **11–14%** GAAP. At this scale, the firm typically has a partner-track / non-partner-track distinction in compensation, and rev/FTE rises because the partner-track ratio of billable revenue to fully-loaded comp is structurally higher than for delivery-staff-only firms. HURN at $277K and FCN at $478K bracket the achievable range; the right target inside that band depends on practice mix (forensic and restructuring premium, general management ops lower) and on geographic delivery mix (US onshore vs. mixed onshore-near-shore).
The cross-cutting variables that move a firm inside these bands: realization (the percent of standard billable rate actually collected on the engagement); concentration (the largest-client revenue share — single-client over 20% is a discount factor in any sale process); recurring revenue mix (retainers vs. project-only); and growth trajectory (Stagwell's +8% organic in Q1 2026 vs. the rest of the agency cohort flat-to-down is the kind of difference that supports a 1.5x rev multiple instead of 1.0x in a sale process). Our companion post on utilization and realization as the two operating metrics that explain agency margin is the read on the first two of those variables; the operating-KPI rebuild work behind it takes 8–12 weeks to land cleanly and sets the baseline data the firm benchmarks against.
- 01 For private firms running an operating review in 2026: Compare yourself to the right sub-segment of the listed cohort. A 30-FTE strategy boutique should benchmark to HURN (not ACN). A 100-FTE creative agency should benchmark to the post-merger Omnicom-Interpublic combined profile (not Stagwell's adjusted EBITDA). Use GAAP operating margin, not adjusted EBITDA, for the cleanest apples-to-apples read.
- 02 For private firms planning an exit in 2026 or 2027: Time the process around the Q1-low / Q3-high seasonality. Open marketing in early-Q4 so trailing-three-month financials cover the seasonal peak; close in Q1 or Q2 so the working-capital normalisation cycle runs on the seller's books. The 3–4 percentage point operating margin swing between Q1 and Q3 is worth real money on a $4–10M EBITDA business.
- 03 For private firms looking at AI-driven productivity gains: Target +3–5% rev/FTE growth in 2026. The listed cohort numbers show rev/FTE flat-to-up YoY across HURN, FCN, OMC standalone, and ACN — the productivity tailwind is being captured, not competed away. Set the target, instrument the measurement, and revisit at Q3 2026 to see whether the AI build-out is landing in the right line of the P&L.
