Add the desk they occupy and the real figure is higher again.
Expressed per completed deal and as a share of the average fee, it becomes the number that tells you whether the team size and the fee level are compatible.
The calculation
Fully loaded cost = salary plus employer on-costs, plus any commission paid, plus the desk they occupy. Divide by the deals they complete for a cost per transaction, and compare that against the average fee to see what proportion of each fee goes on the person who earned it.
Worked example
A 32,000 salary with 20% on-costs is 38,400, plus a 9,575 desk is 47,975 a year. Across 24 deals that is 1,999 per deal, or 44.4% of a 4,500 average fee. They generate 108,000 of fee income against 47,975 of cost, contributing 60,025 toward the rest of the business.
Where the ratio breaks
If the cost per deal approaches half the fee, the remaining half has to cover marketing, management, premises and profit. That is why average fee and deals per head matter more than headcount — adding people without either improving is how an agency grows into a loss.

What are typical employer on-costs?
Twenty to thirty percent of salary in most countries once employer taxes, pension contributions, holiday and sick cover are included. Using salary alone understates the real cost of a hire by roughly a quarter.
Should commission be in the cost?
Yes if it is paid, though it is variable rather than fixed, which changes the risk profile. A commission-heavy structure lowers the fixed cost per deal and raises it on high performers, which is usually the intention.
What is a healthy cost per deal?
It depends on the fee level and how much else the business has to cover. As a rule, if people cost is approaching half the fee, either the fee is too low or deals per head are too few.
