Ask ten brokers what a typical commercial lease commission is and you will get ten ranges, because the honest answer is that it depends. The rate moves with the asset class, the size of the deal, the length of the lease, and which side of the table you are on. This guide explains how commission rates are calculated, what shapes a typical number, and the levers that push it higher or lower. For actual benchmark figures broken out by market, see the dedicated data guide on average commercial leasing commission by US market.
Commercial leasing commissions are not quoted as a single flat fee the way a residential commission often is. There are a few common ways the number is structured, and which one applies changes how you calculate your fee.
Because the structures differ, two deals with the same headline commission can produce very different dollars. Always work from the actual structure in the commission agreement. The mechanics of running the calculation, with a tool to do it for you, are in the guide on how to calculate a commercial leasing commission.
Rates vary widely enough that any single number would be misleading, which is exactly why the by-market data lives in its own guide. What is consistent is the shape: commission rates cluster within a band that shifts by asset class and market, with longer leases often carrying sliding scales and larger deals sometimes negotiated to lower percentages. Rather than anchor on one figure, it is more useful to understand the levers that determine where your specific deal lands.
Different asset classes carry different rate norms. Office, industrial, retail, and medical office each have their own conventions, driven by how those deals are structured and how competitive the leasing is. The asset class you work shapes the baseline you start from.
Larger deals frequently carry a lower percentage, because the absolute dollars are still substantial and landlords negotiate the rate down on big transactions. A smaller deal may hold a higher percentage to keep the fee worthwhile. So percentage and deal size often move in opposite directions.
Longer terms produce larger total lease values, which means a larger commission even at the same rate, and they are also where sliding scales appear, stepping the percentage down in later years. Term length affects both the base the rate applies to and the rate structure itself.
Landlord-side and tenant-side commissions can differ, and on a co-brokered deal the total commission is divided between the two sides. Which side you are on, and how the co-broke is structured, affects your share. The split between firms is covered in the guide on co-broker commission splits.
Read those together and you can estimate where a given deal should land before you ever run the exact math. For the precise calculation, use the calculator guide, and for real benchmark rates by city and asset class, use the by-market data guide.
There is no single average, because rates vary by asset class, market, deal size, and term. Benchmark figures broken out by market are in the dedicated data guide on average commercial leasing commission by US market.
Most commonly as a percentage of the total lease value over the term, or on a per-square-foot basis, sometimes on a sliding scale for longer leases. The exact method is set in the commission agreement.
Because the absolute dollars are already large, landlords often negotiate the rate down on big transactions, while smaller deals may hold a higher percentage to keep the fee meaningful.
