Consultant utilisation rate: What it measures, what it misses, and how to improve it

Most firms know their utilisation rate but few know whether it's telling them the truth.

A consulting firm's utilisation rate is the number everyone watches – the ratio of billable hours to available hours, expressed as a percentage. Hit 75%, breathe easily. Drop to 65%, start asking questions. The number feels objective, clean, and legible in a way that most people metrics aren't.

The problem is what it doesn't capture. Utilisation tells you how busy your consultants are. It doesn't tell you whether they're on the right projects, whether their skills are being used well, or whether the 78% you're proud of is hiding pockets of significant underperformance by practice area or seniority level. Managing by utilisation rate alone is like navigating by average speed. You know you're moving. You don't know where you're going.

This post covers what consultant utilisation rate actually measures, the hidden costs it tends to miss, and what firms that manage it well do differently.

What consultant utilisation rate measures

Utilisation rate is calculated as billable hours divided by total available hours, multiplied by 100. If a consultant has 160 available hours in a month and works 120 billable hours, their utilisation rate is 75%.

Most firms set a target somewhere between 70% and 85%, depending on their model. Higher targets leave little room for business development, internal work, and professional development – activities that matter for long-term health but don't show up in the billable column. Lower targets start to erode margins at the rate you'd expect.

At the firm level, a useful benchmark: a 1% improvement in utilisation across 100 consultants billing at €120 per hour adds approximately €153,000 in recovered revenue per year. At 400 consultants, a 3% improvement represents over €2.5 million. These are not edge cases – they're the standard returns on running a tighter resourcing operation.

What utilisation rate typically misses

The headline rate is useful. The pattern underneath it is where the real information lives.

It averages over the wrong things. A firm with a 76% utilisation rate might have a senior practice billing at 90% – close to burnout and likely to turn down development opportunities – while a junior cohort sits at 58%. The average obscures both problems.

It doesn't distinguish good allocation from bad. A consultant allocated to a project that doesn't match their skills is technically billable. But if they're being used for tasks below their capability or outside their expertise, you're running two risks simultaneously: you're likely delivering below the quality you'd want, and you're likely losing the consultant to boredom or frustration sooner than you'd planned.

It arrives too late. Utilisation reporting is almost always retrospective. It tells you what happened last month. The more useful question – who is coming off projects in the next four to six weeks, and where are the incoming gaps? – requires a different kind of visibility entirely.

It doesn't connect to skills. The reason a particular consultant sits at 62% might be that their skills profile is genuinely narrow. Or it might be that nobody knows they have a relevant certification because it's on a CV that hasn't been updated in three years. These are very different problems with very different solutions – and a proper skills gap analysis will tell you which one you're dealing with, where a utilisation dashboard won't.

The connection between skills visibility and utilisation

The single most common cause of under-utilisation isn't lack of work – it's slow matching. The work exists in the pipeline; the person who could do it is sitting available; but nobody has connected the two quickly enough, and by the time they do, the project has either started with the wrong person or the available consultant has been allocated to something that's a loose fit.

This is a skills visibility problem. Firms that can answer "do we have anyone with X certification, available in three weeks, not already committed to another bid?" in seconds will consistently outperform firms where that question takes three days and three conversations to resolve. The utilisation gap is, in many cases, a search problem with a data solution.

The firms that get this right have built a live, searchable picture of their workforce – not a spreadsheet updated monthly, and not LinkedIn profiles that reflect job-seeking ambitions rather than actual daily capability. They know what their people can do, at what proficiency, with what certifications, and when they're free. That's the foundation for managing utilisation actively rather than measuring it retrospectively.

Practical approaches to improving consultant utilisation

There is no single intervention that moves utilisation rate. It's a system problem that requires a systems response.

Move from reactive to predictive staffing. Rather than matching people to projects when a gap opens, track project end dates and pipeline probability together. If you know a senior consultant finishes a project in six weeks and a probable engagement requiring their skills closes in four, you can have the conversation now – before the bench begins.

Differentiate bench from investment. Not all non-billable time should be treated as a problem. Consultants working on internal IP, contributing to proposals, or completing certifications are not bench – they're building future capacity. Firms that conflate the two end up applying pressure in the wrong places and losing people who were actually being productive. For a fuller breakdown of how to manage this distinction, see bench management in consulting.

Make skills data a resourcing input, not an HR artefact. Skills profiles that live in the HR system but don't reach the resource manager are not resourcing tools. The point is to get the right capability data into the hands of the people making staffing decisions – fast enough to actually influence those decisions.

Track utilisation by segment, not just overall. Senior consultants have different utilisation dynamics than junior staff. Practice areas have different demand cycles. A single firm-level number hides all of this. Monthly averages hide more. The useful view is current utilisation by team and seniority, with forward-looking availability mapped against the pipeline.

How MuchSkills supports utilisation management

MuchSkills gives consulting firms a live view of consultant availability, allocation, and upcoming capacity – alongside a searchable, validated picture of skills, certifications, and proficiency. When a new brief arrives, AI Super Search lets you search the entire workforce by skill and availability simultaneously. Team Builder shows you who fits the brief, who is free, and where gaps exist before you commit. For firms that also respond to RFPs, CV Inventory generates tailored proposal CVs from the same live skills data.

The result is that the matching problem – the slow, conversational process that sits at the root of most utilisation underperformance – gets resolved in minutes rather than days. Consultants spend less time on the bench waiting for the right allocation. Resource managers spend less time chasing information that should be immediately visible.

For firms managing 100 to 500 consultants, that shift in matching speed translates directly into utilisation rate. Not as a projection – as an operational reality you can see in the numbers month by month.

Frequently asked questions

What is a good consultant utilisation rate? 

Most consulting firms target between 70% and 85% billable utilisation, depending on their model and the expectations around non-billable activities such as business development, internal projects, and professional development. Higher is not always better – consistently high utilisation with no slack for development or pre-sales work tends to create retention problems and delivery risk over time.

How do you calculate consultant utilisation rate? 

Divide the number of billable hours by the total available hours in the period, then multiply by 100. For example, a consultant with 160 available hours who bills 120 hours has a 75% utilisation rate. Some firms calculate this on a target-hours basis rather than available-hours basis – the method you use matters less than applying it consistently.

What causes low utilisation rates in consulting? 

The most common causes are slow project matching when new work arrives, poor visibility into upcoming project end dates, and skills data that isn't accessible or searchable when staffing decisions are being made. Firms that improve their utilisation rate most reliably do so by solving the matching problem – connecting available consultants to incoming work faster, based on accurate skills and availability data.

What's the difference between utilisation rate and bench rate? 

Bench rate is the inverse of utilisation rate – it measures the percentage of available time that is not billable. A 75% utilisation rate implies a 25% bench rate. Some firms track both; others only track utilisation. The more useful distinction is between bench time that is genuinely unproductive (no allocation, no structured activity) and non-billable time that serves a purpose – pre-sales, professional development, internal projects.
