# Revenue per professional: the headline benchmark everyone quotes
Deloitte reports roughly $67 billion in global annual revenue. A boutique strategy shop with 40 consultants might report $30 million. Comparing those two numbers tells you nothing. Comparing revenue per professional tells you almost everything about how each firm actually makes money.
This single ratio, calculated a few different ways, is the first thing bankers, recruiters, and partners themselves check when sizing up a professional services firm. This lesson shows you how to calculate it properly, normalize it across firms of different sizes, and avoid the comparison traps that trip up even experienced analysts.
Professional services firms (law firms, accountancies, consultancies, investment banks' advisory arms) sell hours and expertise, not products. Revenue scales with people, not factories or inventory. So the natural denominator isn't revenue alone, it's revenue divided by the people generating it.
This gives you two core metrics:
RPP tells you how much value each owner extracts. RPE tells you how efficiently the whole firm converts labor into revenue.
$$\text{Revenue per Partner} = \frac{\text{Total Firm Revenue}}{\text{Number of Equity Partners}}$$
$$\text{Revenue per Employee} = \frac{\text{Total Firm Revenue}}{\text{Total Headcount}}$$
Worked example. Take a mid-size US law firm reporting $500 million in annual revenue, with 100 equity partners and 1,000 total staff (partners, associates, and support staff combined).
Now compare a boutique advisory firm: $40 million revenue, 8 partners, 80 total staff.
Identical ratios despite a 12x size gap. That's the point of normalizing: it lets you compare a giant and a boutique on the same footing, and here it reveals both firms monetize talent with equal intensity, even though one is far larger.
Here's where sector knowledge matters, because raw ratios vary hugely by business model.
Big Four accountancies (Deloitte, PwC, EY, KPMG) mix low-margin audit work with higher-margin advisory and tax. As of recent public reporting (fiscal year 2024, figures are estimates compiled from firms' own annual releases), global revenue per partner across the Big Four is commonly cited in the $1.5 million to $2.5 million range, varying by firm and region, with UK and US partners often at the higher end. Revenue per employee across the whole Big Four workforce (which includes large audit teams and junior staff) tends to sit around $300,000 to $400,000, an estimate, because audit is labor-intensive and lower-margin than advisory.
Elite strategy consultancies (McKinsey, BCG, Bain, collectively "MBB") run leaner, higher-margin models. Widely cited industry estimates put partner-equivalent (senior partner/director) revenue contribution well above $3 million to $5 million, and revenue per consultant in the $500,000 to $900,000 range, though these firms are private and do not publish audited figures, so treat any specific number as a directional estimate, not fact.
European boutiques (small M&A advisory shops, specialist tax boutiques) often report RPP figures comparable to or exceeding Big Four averages, precisely because they carry no large audit-junior base dragging the denominator up. A 10-partner London boutique doing $60 million in advisory fees would show RPP of $6 million, which looks "better" than a Big Four number but reflects a completely different business mix, not necessarily better management.
The takeaway on comparability: RPP and RPE are only meaningful when you know the service mix (audit vs. advisory vs. legal vs. strategy), because margins and staffing ratios differ structurally across those lines, not just by firm quality.
A number that helps you interpret RPP is the leverage ratio: the number of non-partner staff per partner.
$$\text{Leverage Ratio} = \frac{\text{Total Staff} - \text{Partners}}{\text{Partners}}$$
Using the law firm example: (1,000, 100) / 100 = 9:1.
High leverage (many juniors per partner) usually means a firm builds RPP by scaling junior labor under each partner, common in Big Four audit practices, where leverage often runs 15:1 or higher. Low leverage (closer to 3:1 or 4:1) is typical of elite boutiques and MBB partners, where fewer, more senior staff work directly with clients at premium rates.
Two firms can post identical RPP with very different leverage, and that difference tells you whether growth in revenue per partner is coming from more staff hours billed out, or from higher rates charged by senior people. For a primer on how professional service firm economics generally work, see the Harvard Business Review's overview of the "professional service firm" model.
Before you compare RPP or RPE across firms, check three things:
1. Non-equity partners: some firms count "salaried partners" (employees with a partner title but no equity stake) in the denominator, artificially lowering RPP. Always ask whether the number is equity partners only.
2. Revenue recognition: consulting firms sometimes include reimbursed expenses (travel, subcontractor costs) in gross revenue, inflating the numerator. Net fee revenue is the cleaner comparison.
3. Part-time and contract staff: RPE calculated on headcount versus full-time equivalents (FTEs, a standardization measure converting part-time roles into their full-time hour equivalent) can differ by 10 to 20 percent for firms with large flexible or contractor pools.
Vérification des acquis
1. Why is comparing total revenue between a global firm and a boutique firm misleading?
2. What does revenue per partner (RPP) primarily measure that revenue per employee (RPE) does not?
3. A firm narrows its RPE calculation to only client-facing staff instead of total headcount. What is the main effect of this choice?

If you're pulling numbers from annual transparency reports (which UK and EU audit firms are required to publish under EU Audit Regulation and equivalent UK rules), the calculation is simple arithmetic once you have clean inputs:
revenue = 45_000_000 # total firm revenue, GBP
equity_partners = 12
total_headcount = 310
rpp = revenue / equity_partners
rpe = revenue / total_headcount
print(f"Revenue per partner: £{rpp:,.0f}")
print(f"Revenue per employee: £{rpe:,.0f}")This outputs Revenue per partner: £3,750,000 and Revenue per employee: £145,161. The hard part isn't the math, it's sourcing consistent, comparable inputs across firms that define "partner" and "revenue" differently.
