What Is a Good Utilization Rate for Consultants? The Real Benchmark
What is a good utilization rate for consultants? Every agency owner has asked it, staring at a utilization report that keeps sliding left. The question is simple, and almost nobody answers it with data.
The problem is that the number you're chasing keeps moving. The latest industry benchmark data shows billable utilization fell to its lowest level in nearly two decades, while the firms that run the numbers honestly still hold a very specific band. The gap between those two — between average and good — is where margin quietly disappears.
This post gives you the real benchmark, the target by role, and what a single point of utilization is actually worth in dollars. It builds on what we covered in billable vs non-billable hours — that post explains the difference, this one puts a number on the healthy mix — and on the founder workweek data showing how those hours actually split.
The Real Benchmark: 66.4% and Falling
The most current industry-wide reading comes from SPI Research's 19th annual Professional Services Maturity Benchmark, built on 2025 survey data from 509 firms representing more than 245,000 employees and $63 billion in services revenue. The headline number: billable utilization fell to 66.4% — the lowest reading in the study's 19-year history, down from roughly 75% a decade ago.
An earlier edition of the same study, cited by Saibon Group's 2025-2026 benchmark breakdown, put the 2024 figure at 68.9% across 403 firms — also the lowest since 2019. The two numbers come from different survey waves, but they agree on direction: utilization has been sliding for years, and the average firm now leaves roughly a third of its paid capacity unbilled.
Statista's sector-level data confirms the spread: benchmark utilization varies by industry segment, with architecture and engineering firms reporting the highest employee billable utilization among professional services organizations worldwide.
Here is the number to internalize: the industry average utilization rate is around 66-69% — and it has been falling for five straight years. "Good" is not the average.
What "Good" Looks Like by Role
Every serious source lands in the same band for healthy firms, even when they phrase it differently. CommandOS's consulting benchmarks put healthy billable utilization at 70-75%, with top-quartile firms sustaining 75% or more without burning people out. Harvest's utilization guidance calls 70-80% a realistic target for service businesses. Everhour's consulting calculator puts delivery consultants at 70-80%, with a higher blended rate for agencies.
One number for the whole firm is the classic mistake — the target should flex by role. A junior consultant has no sales or management load and can sit at 80-85%. A senior consultant delivering complex work holds 70-80%. A partner carrying business development and firm-building responsibilities might realistically land at 40-50%. The blended firm-wide average is always lower than the delivery-only number, because partners, managers, and sales support pull it down. Saibon's data makes the revenue consequence concrete: firms at the industry-average 68.9% utilization generated about $199,000 in revenue per consultant in 2024, while firms holding the 75% threshold generated well above that — roughly $216,000 at the same billing rates and cost base.
| Role | Typical target | Why |
|---|---|---|
| Junior consultant | 80-85% | No sales or management load |
| Senior / delivery consultant | 70-80% | Complex delivery, some oversight |
| Manager / principal | 60-75% | Review, staffing, client management |
| Partner | 40-50% | Sales, proposals, firm building |
| Blended firm-wide | 70-75% | Healthy floor for the whole P&L |
Sustaining above 85% at an individual level is a warning sign, not a badge of honor — it usually means no time for training, business development, or recovery, and it predicts burnout and turnover. Non-billable time is not the enemy. The enemy is non-billable time you did not budget for and only discover at the monthly report.
What One Point of Utilization Is Worth
The reason utilization math matters is that a single percentage point is real money. Beancount's utilization economics breakdown makes the arithmetic concrete: one consultant at 70% utilization bills 28 hours a week — about $268,800 a year at typical rates, against a loaded cost that doesn't move when utilization dips.
Move that consultant from 68% to 70.5% — roughly 2.5 points — and annual revenue rises about $9,600 per person, or $96,000 across a ten-person firm. The salary cost does not change at all, so most of that falls straight to margin. Conversely, a consultant sitting fully on the bench for a month at an $85-per-hour loaded cost burns roughly $13,600 in carrying cost while exposing about $32,000 in unbilled revenue capacity.
Harvest's calculator drives the same point home at firm level: a 20-point utilization gap across five people means about $21,650 less revenue a month — $259,800 a year — with payroll unchanged. For a three-person studio dropping from 75% to 65%, that's the equivalent of losing nearly a full salary in billable capacity with zero reduction in payroll. Every point you recover before the bench grows is margin you never have to sell a new client to get.
Why Utilization Keeps Falling — and the Mistakes That Rig the Number
The decline isn't mysterious. Saibon's analysis ties it to slower revenue growth, economic uncertainty delaying client timelines, and an operational matching problem: the gap between a consultant becoming available and that consultant being proposed to a client. Firms that close that gap faster hold utilization; firms that discover availability at the monthly report lose it.
Just as important is measuring honestly. The most common errors that rig the number, flagged in Beancount's five-mistakes list: playing denominator games with available hours, confusing invoiced hours with delivery hours, forcing eight billable-looking hours a day, setting one target for every role, and treating utilization as if it were profitability. A number that looks healthy because it was measured loosely is worse than an honest low one — it hides the margin problem until the year-end financials reveal it.
What Good Looks Like
Firms that keep utilization in the healthy band do three things differently. First, they set targets by role and communicate them — a partner at 40-50% is not a failure, and a junior at 80% is not a miracle. Second, they track the leading indicators, not just the monthly headline: who goes available next week, how long proposals take, how much quiet time each person actually has. Third, they keep the billable engine visible so the data is never a surprise discovered at month end.
Visibility is the hard part in practice, because the work happens across Slack, email, and chat threads — not in a timesheet that anyone fills in on time. The matching problem Saibon identifies — a consultant going available only to be discovered three weeks later — is fundamentally a visibility problem, and it is the biggest single lever most firms never pull. That's where Project Intelligence in Asa.Team fits: it surfaces project updates from Slack, Teams, Telegram, and WhatsApp automatically, so a consultancy lead sees which projects are moving, which are stalled, and where capacity actually sits — without chasing status updates across five apps. The timesheet stays honest because the work behind it is visible.
Frequently Asked Questions
What is a good utilization rate for consultants?
A healthy firm-wide utilization rate is 70-75%, with top-quartile firms sustaining 75% or more. Individual targets vary by role: 80-85% for juniors, 70-80% for delivery consultants, 40-50% for partners carrying sales responsibility.
What is the average utilization rate for consultants?
The industry average sits around 66-69% in the latest SPI Research Professional Services Maturity Benchmark — the lowest level in the study's 19-year history. The average has been falling for five straight years, which is why "average" is not a good target.
Is 100% utilization realistic or even good?
No. Sustaining above 85% for a delivery consultant usually means no time for training, business development, or recovery — it predicts burnout and turnover. Healthy utilization always leaves room for sales, proposals, and firm-building work.
How do you calculate consultant utilization rate?
Divide billable hours by available hours. For example, with 1,760 available hours a year (220 working days × 8 hours), a consultant billing 1,320 client hours has a 75% utilization rate. The denominator matters — net available hours after PTO and holidays is the honest basis.
The Bottom Line
The short answer: a good utilization rate for consultants is 70-75% firm-wide, set by role, measured honestly — while the industry average sits near 66% and falling. The difference between the two is not a dashboard aesthetic; it is the difference between a firm that leaves a third of its capacity unbilled and one that converts that capacity into margin.
If you don't know your utilization rate this week, the first step is not a new target — it's visibility. Start by tracking the projects and the time behind them in one place, and let the number tell you where the bench really is. The firms that recovered from the 2024-2025 low did exactly that: they made the billable engine visible before they tried to fix it.
