Revenue per employee: formula, a worked example by practice, and how to compare it

Revenue per employee is annual revenue divided by the average number of full-time equivalent (FTE) employees during the year. A professional services firm with $74.5 million of revenue and 364 average FTEs brings in about $204,670 per employee. Use the average, not the year-end headcount, and compare only with your own history and with peers in the same industry.

The formula

Revenue per employee = Revenue / Average FTE employees

Average FTE = (FTE at start + FTE at end) / 2, or the average of the monthly FTE counts

FTE = Total hours worked / Standard full-time hours

Three choices decide whether the figure means anything:

• Average, not year-end. Revenue is earned across the year, so the denominator should cover the year too. In a year of hiring, year-end headcount understates the ratio.
• FTE, not heads. Two people on half-time contracts are one FTE. Counting heads makes a part-time-heavy team look unproductive.
• Who counts. Employees on the payroll, converted to FTE. Contractors who do the client work should be shown alongside, in their own line, because a team that subcontracts will otherwise look more productive than it is.

Worked example: a professional services firm by practice

One year, five practices. In Excel, with revenue in USD millions in B2:B6, FTE at start in C2:C6 and at end in D2:D6, average FTE in E2 is =AVERAGE(C2:D2) and revenue per average FTE in F2 is:

=B2*1000000/AVERAGE(C2:D2)

Advisory, step by step: (72 + 80) / 2 = 76 average FTEs, and 18,600,000 / 76 = $244,737. The firm figure is 74,500,000 / 364 = $204,670.

On year-end headcount instead, the firm shows 74,500,000 / 378 = $197,090, about 3.7% lower, because the firm grew during the year. Technology consulting shows the effect most: it hired 10 people, and its figure on year-end headcount is 15,300,000 / 54 = $283,333 rather than $312,245. Outsourced accounting shrank, so for it the year-end figure is higher ($112,500).

Why the firm total is not the average of the practices

The simple average of the five practice figures is $211,726, about $7,000 too high. It gives outsourced accounting's 65 people and technology consulting's 49 the same weight as audit's 114. The firm figure weights every practice by its FTEs, which is the same as dividing total revenue by total FTEs:

=SUM(B2:B6)*1000000/SUM(E2:E6)       correct: 204,670
=AVERAGE(F2:F6)                      wrong:   211,726

The same trap, the difference between a count-weighted and a value-weighted average, is worked through in count-weighted and value-weighted.

The check that proves it

Three ties before the figure goes in a report:

1. Revenue sums. 18.6 + 12.4 + 21.0 + 15.3 + 7.2 = 74.5 must equal revenue in the ledger for the year.
2. FTEs sum. 76 + 60 + 114 + 49 + 65 = 364 must equal the firm's average FTE from the payroll or HR system.
3. Weighted average rebuilds the firm figure. Each practice's figure times its FTEs returns its revenue (244,737 × 76 = 18.6 million), so the FTE-weighted average of the practice figures is 74,500,000 / 364 = $204,670 again.

Revenue per employee by industry

The ratio follows the business model more than the effort of the people. Energy producers, commodity traders and technology platforms put large revenue through small, capital-heavy or software-heavy workforces. Retailers, hospitality and professional services sell the time of many people, so their ratios run far lower. A distributor that books the full price of the goods it resells runs higher than a consulting firm of the same size, without being more productive.

So build the peer set inside your own industry. For public companies, two lines of a Form 10-K give the inputs: revenue in the income statement, and the employee count, which Regulation S-K Item 101(c) requires as part of "a description of the registrant's human capital resources, including the number of persons employed by the registrant." Each company chooses its own definition and date, so record both.

Companies with the highest revenue per employee

Rankings published elsewhere mix definitions, years and revenue measures. Four companies from different industries, computed from their latest 10-K filings, show the spread:

Revenue is Exxon Mobil's sales and other operating revenue (excluding equity-affiliate and other income), Apple's total net sales, Costco's total revenue including membership fees, and Accenture's revenues. Exxon Mobil's regular employees include part-time staff covered by its benefit plans. Each figure divides by the year-end count, because that is what the filings report; with averages the order would not change.

Exxon Mobil and Apple sit at the top because oil and gas and devices move enormous revenue per person. Accenture, a professional services firm, sits near the range of the worked example above: firms that sell people's time all do.

What it hides

• Outsourcing. A practice that subcontracts the work keeps the revenue and drops the people, so its ratio rises with no change in productivity.
• Contractors. Leaving out contractors who deliver client work inflates the ratio in exactly the units that use them most.
• Pass-through revenue. Expenses rebilled to clients, or goods resold at full price, add revenue without adding work.
• Margin. A high ratio on thin margin can earn less than a low ratio on a fat one. Pair it with profit per employee (operating profit / average FTE), and in professional services with utilization against realization per consultant.

Where it goes wrong

• Year-end headcount in a year of growth. It understates the ratio, by 3.7% for the firm above.
• Heads instead of FTEs. A part-time-heavy practice looks unproductive.
• Contractors excluded. The ratio is inflated for units that outsource.
• Comparing across industries. A distributor with pass-through revenue and a consulting firm are not comparable.
• Averaging the practice ratios. The firm figure is total revenue over total FTE.

Revenue per practice and per person

The firm figure hides practices and people. Covirage's tools compute revenue, utilization and realization per practice from your time and billing exports and check they sum to the firm total; the external AI model explains the differences and never does the arithmetic. See Covirage for professional services, and practice KPIs for tax and accounting firms for the measures behind the tax and audit rows. For the measures it sits beside, see financial KPIs, KPI examples and the Rule of 40.
