Ask an agency leader how busy the studio is, and the answer is almost always "flat out". Ask the same leader what their billable utilisation rate was last week, and the answer usually takes a lot longer to arrive — if it arrives at all. That gap is not a curiosity. It is where a meaningful share of agency profit quietly disappears every year.

Utilisation, the share of paid time that ends up sold to clients, is the master lever of agency profitability. Pricing matters. Scope discipline matters. But utilisation sets the ceiling on everything else, because capacity the agency has already paid for and fails to sell is gone for good — no rate card wins it back. This guide sets out the current agency utilisation rate benchmarks, the resource planning habits that move the number, and where agency capacity planning typically breaks down.

What is a healthy agency utilisation rate?

SPI Research's 2025 Professional Services Maturity Benchmark, covering 403 firms, found billable utilisation fell to 68.9% in 2024 — the lowest reading in five years, and below the roughly 75% level the industry generally considers healthy.[1] That is the headline billable utilisation benchmark to hold in mind: most firms, right now, are running below where they should be.

Benchmarks vary by discipline. Creative and advertising agencies typically target around 70% utilisation, reflecting the non-billable weight of pitching, admin and internal work; consulting firms tend to run higher, at 74–84%.[2][3] The floor matters as much as the ceiling: practitioner analysis from Mosaic suggests that below roughly 74% utilisation, revenue per employee tends to fall beneath break-even for many firms.[3] An agency drifting along in the high 60s can feel busy and still be underwater on its own payroll.

A word on definitions, because they generate more disagreement than the numbers themselves. Utilisation here means billable hours as a share of available hours. Agencies differ on the denominator — some divide by contracted hours, some deduct leave and training first, some exclude directors entirely. Any of these can work. What matters is picking one definition, applying it consistently across the team, and tracking it weekly; a number defined differently every quarter cannot be managed at all.

The twin failure: busy is not the same as billable

Utilisation fails in two directions, and most agencies manage neither well. Under-utilisation is the quieter failure. Every point below target is salary spent with nothing invoiced against it, and it rarely looks like idleness from the inside — people are occupied with internal projects, proposals, meetings and admin while the billable share of their week quietly sinks.

Over-utilisation is the failure agencies inflict on their best people. Above roughly 85%, resource-management research warns that burnout risk climbs and quality drops, because there is no slack left for thinking, mentoring or the unglamorous internal work that keeps an agency functioning.[2][3] Sustained peaks are typically followed by resignations, and the cost of replacing and retraining the people who leave lands straight back on the P&L.

Here is the trap: the two failures coexist constantly. More than three-quarters of creative agencies report routinely working beyond agreed scope without billing for it, and well over half lose meaningful monthly revenue to unbilled or out-of-scope work.[4][5] That over-serviced effort is real work by real people — it exhausts the team without ever registering as billable time. The result is an agency that is simultaneously overworked and under-utilised: staff at their limit, and a utilisation number sitting below break-even.

Busy is not the same as billable. Plenty of exhausted teams work inside under-utilised agencies.

What ten points of utilisation is actually worth

Resource-management analysts keep making the same point: a modest utilisation gap produces an outsized gap in gross profit, because the payroll underneath is identical either way. For a 20-person agency, the difference between 65% and 75% utilisation can be worth more than the entire year's net profit — the white paper works that example through, line by line.

Why agencies fly blind on resource planning

Two habits do most of the damage: capacity is planned in spreadsheets that are stale by Tuesday and describe hours that never existed, and time is captured late and wrong, so utilisation reporting is fiction reported to one decimal place. Every downstream decision — including hiring — inherits the fiction.

Two disciplines that fix agency capacity planning

The fix comes down to two disciplines run weekly rather than quarterly: plan to real capacity, and capture time at the source. Neither is conceptually hard — what defeats agencies is running them by hand across systems that do not talk — and the white paper turns both into an operating routine, thresholds included.

This guide tells you where the benchmark sits and why busy is not the same as billable. The white paper does the part that changes budgets: the ten-point example worked to the pound, the healthy band by discipline, and the two disciplines — planning to real capacity, capturing time at the source — as a weekly routine your traffic manager could start on Monday.

Find your own ten points

Three questions worth asking at your next leadership meeting: what was our utilisation last week, not last quarter? Who on the team is above 85% right now? What did over-servicing cost us last month? If those questions take days to answer, capacity is being managed on instinct — and the ten points are hiding in the gap between what was planned and what actually happened.

Your people are the product. Utilisation is simply the measure of how much of that product ever reaches a client. Against a 13% net margin, every recovered point of utilisation lands close to straight on the bottom line.
