Consulting firm EBITDA hit 9.8% in 2024, the lowest point in five years and nearly half what it was in 2022. If you run a consulting firm and your margins have felt tighter than they should, the data confirms it isn't just you.

The 2025 SPI Professional Services Maturity Benchmark, covering 403 firms across IT consulting, management consulting, engineering, and professional services, is the most comprehensive picture of where the industry stands. The findings are stark. But buried in the same report is an equally important story: what the high performers did differently.

TL;DR: Key Takeaways

• Consulting firm EBITDA fell to 9.8% in 2024, down from 15.4% in 2023, a 5-year low (SPI Research 2025)

• Billable utilization dropped to 68.9%, below the 75% optimal threshold, for the third straight year

• Top-tier firms (Level 5) outperform low-maturity peers by +265% on EBITDA and +36.4% on billable utilization

• Nearly 80% of high-performing firms use Professional Services Automation (PSA), linked to 28% higher EBITDA

• The margin gap is operational, not strategic: the firms winning manage bench time and resource visibility differently

The Headline Number: Consulting Firm Profitability at a 5-Year Low

According to the 2025 SPI Professional Services Maturity Benchmark (published February 2025, 403 firms surveyed), consulting firm profitability declined sharply across every key metric in 2024:

• EBITDA: 9.8%, down from 15.4% in 2023 and 16.1% in 2022

• Billable utilization: 68.9%, below the 75% optimal threshold for the third consecutive year

• Revenue growth: 4.6% YoY, less than half the 10-year industry average

These aren't small fluctuations. A firm generating €5M in revenue at 15.4% EBITDA books €770K in profit. At 9.8%, that same firm books €490K, a €280K swing on no change in revenue. For mid-sized consulting firms, that's the difference between investing in growth and cutting headcount.

The pressure came from multiple directions simultaneously: economic uncertainty slowing client spend, increased competition (including from ex-consultants going independent), and rising delivery expectations without proportional fee increases. But the underlying operational driver, the one firms can actually control, is utilization.

Three Years of Declining Utilization, and Why It Compounds

Billable utilization is the single most important operational metric for consulting firm profitability. When a consultant is unbilled, that cost doesn't disappear. It stays on your payroll while generating zero revenue. At a daily rate of €900 and 20 bench days per consultant per year, a 50-person firm loses approximately €900,000 annually in unrealized revenue.

The 2025 SPI data shows utilization has declined for three straight years, now sitting at 68.9%. The industry optimal range is 70–80%, what SPI Research calls the "Goldilocks Zone" for sustainable profitability. Firms operating below 70% face a compounding problem: lower utilization shrinks EBITDA, which reduces investment capacity, which slows the operational improvements that would fix utilization in the first place.

This is why the gap between high-maturity and low-maturity firms keeps widening, not narrowing.

What the Top Performers Did Differently

The SPI 2025 Benchmark segments firms by maturity level (Level 1–5). The performance gap between the top and bottom is not incremental. It's transformational. Level 5 firms outperform Level 2 peers by:

• +433% in revenue growth

• +265% in EBITDA

• +36.4 percentage points in billable utilization

These aren't firms with fundamentally different service lines or client bases. They're operating in the same market with the same macroeconomic headwinds. The difference is operational. Three patterns stand out consistently.

1. Professional Services Automation (PSA) Is Standard, Not Optional

Nearly 80% of high-performing consulting firms use a PSA solution, and most integrate it with their core financials. According to the SPI 2025 data, firms running PSA tools show:

• 10% higher billable utilization

• 24% higher project margin

• 28% higher EBITDA

The logic is straightforward. When resource availability, skills, and project demand live in a single system rather than across spreadsheets and email threads, matching decisions get faster and more accurate. A consultant doesn't sit on the bench for two weeks because a manager didn't know they were available. The system surfaces them automatically.

2. Real-Time Resource Visibility Replaces Reactive Staffing

Low-maturity firms typically run resource planning on a weekly cycle: a manager emails the team, collects availability responses, and builds a picture of who can go where. By the time that picture is complete, two things have happened: a client request has already been answered (or not), and bench time has already accumulated.

High-maturity firms operate differently. They have live visibility into who is available, what skills they hold, and when projects are expected to end. This shifts resource management from reactive (filling gaps after they open) to proactive (anticipating gaps before they cost money). The SPI data links this directly to margin: firms with integrated real-time data consistently show higher utilization and lower bench costs.

3. Speed-to-Match Drives Both Revenue and Win Rate

When a client opportunity lands – whether an RFP, a direct request, or an account expansion – the speed at which a consulting firm can respond with the right consultant profile correlates directly with win rate. Firms that respond within hours consistently outperform those that take days.

This isn't a sales problem. It's an operational one. If your consultant database is a folder of outdated CVs and your availability tracking lives in someone's head, every response to a client opportunity takes hours of admin before it can even start. Top-performing firms have solved this by treating their consultant pool as a live asset: always current, always searchable, always ready to be surfaced.

The "Ghost Bench" Problem: Where Margin Disappears

One of the least-discussed drivers of low consulting firm profitability is what we call the ghost bench: consultants who are available and ready to be placed, but effectively invisible to buyers because no one has surfaced them.

Ghost bench costs accumulate in three ways:

1. Delayed matching: a consultant sits unplaced for 1–2 weeks because the firm's manual process hasn't caught up with their availability

2. Missed inbound demand: a buyer asks for a profile and the firm doesn't know they have the right person

3. Reactive external hiring: the firm brings in a contractor or freelancer for a role that a benched consultant could have filled

Each of these is an operational failure, not a market failure. And in aggregate, they explain a significant portion of the utilization gap between top and bottom performers.

According to SPI Research, firms that invest in automation and integrated resource management eliminate most ghost bench scenarios, because availability is visible, skills are searchable, and matching is automatic rather than manual.

How to Close the Profitability Gap in 2025

The 2025 benchmark makes the intervention clear. Firms that recover their margins aren't doing so through pricing power or new service lines alone. They're closing the operational gap that lets bench time accumulate and matching slow down.

The practical steps:

1. Get a single source of truth for your consultant data. Fragmented CVs across email, SharePoint, and individual folders guarantee that some consultants will always be invisible when demand arises. Consolidating profiles, with live availability, skills, and history, is the foundation everything else depends on.

2. Automate the match, not just the database. A consultant directory is necessary but not sufficient. The operational win comes when the system actively surfaces consultants when they hit the bench, matching them to live demand automatically, without requiring a manager to run a manual search.

3. Measure speed-to-match as a KPI. Most consulting firms don't track how long it takes from a client request to a submitted consultant profile. The firms that do, and optimize against it, consistently show higher win rates and better utilization than those who treat it as an unmeasured process.

4. Act on bench risk before it becomes bench time. High-maturity firms know, 4–8 weeks out, which consultants are finishing projects and when. That lead time makes the difference between a proactive placement and reactive scrambling.

The consulting firms that came through 2024 with margins intact didn't find a magic strategy. They closed the operational gap, and the profitability followed.

FAQ

What is the average consulting firm profitability (EBITDA) in 2025?

According to the 2025 SPI Professional Services Maturity Benchmark (403 firms, published February 2025), the average consulting firm EBITDA fell to 9.8% in 2024, the lowest figure in five years and a significant decline from 15.4% in 2023. The optimal EBITDA benchmark for a healthy consulting firm is typically 15–20%, making 2024 a challenging year for the industry.

What is the average consultant utilization rate in 2025?

The 2025 SPI Benchmark reports billable utilization at 68.9% across professional services firms, below the 75% optimal threshold and continuing a three-year downward trend. Most consulting firms target a utilization rate between 70–80% for sustainable profitability. Falling below 70% creates compounding margin pressure because bench costs are fixed while billable output shrinks.

Why are consulting firm margins declining?

Consulting firm margins declined in 2024 due to a combination of economic uncertainty slowing client spend, increased competitive pressure, and operational inefficiencies, particularly in resource management. The primary controllable driver is billable utilization: firms that manage bench time poorly see bench costs erode EBITDA even when revenue holds steady. The SPI 2025 data shows a direct correlation between resource management maturity and profitability.

What do high-performing consulting firms do differently?

According to the SPI 2025 Professional Services Maturity Benchmark, top-tier consulting firms (Level 5) outperform low-maturity peers by +265% on EBITDA and +36.4 percentage points on billable utilization. Nearly 80% of high-performing firms use Professional Services Automation (PSA) integrated with their financials – linked to 28% higher EBITDA, 24% higher project margin, and 10% higher utilization. They also operate with real-time resource visibility rather than weekly manual planning cycles.

How does PSA software affect consulting firm profitability?

Consulting firms using Professional Services Automation (PSA) software show measurably better financial outcomes than those relying on spreadsheets and manual processes. The SPI 2025 Benchmark found that PSA-adopting firms achieve 10% higher billable utilization, 24% higher project margin, and 28% higher EBITDA compared to non-adopters. The mechanism is operational: PSA tools give firms real-time visibility into resource availability, enabling faster and more accurate matching decisions.

What is the "ghost bench" in consulting?

The ghost bench refers to consultants who are available and ready to be placed but are effectively invisible to buyers because no live system tracks their availability. Ghost bench scenarios arise from delayed matching, fragmented CV databases, and reactive staffing processes. Unlike visible bench time, ghost bench costs are harder to measure – but they contribute significantly to below-average utilization rates and are a direct driver of margin erosion for firms without automated resource management.

Saibon automates consultant matching and bench intelligence for consulting firms, so available consultants get surfaced to buyers automatically, not after two weeks of email chains. See how it works.
