Leasing Commission Structures in Commercial Real Estate: Broker Compensation, Co-Brokerage Splits, and Pro Forma Modeling

Key Takeaways

What Leasing Commissions Are and Who Pays

A leasing commission is the fee paid to a real estate broker for negotiating and closing a commercial lease. It is common for the landlord to pay the commission, as Realized 1031's leasing commission glossary notes. The listing broker (who represents the landlord) and the tenant representation broker (who represents the tenant) are commonly both compensated from the landlord's funds. The tenant typically does not pay the commission directly, although the cost is embedded in the landlord's economics and, over time, is reflected in asking rents across the market.

The same glossary explains that leasing commissions are typically calculated as a percentage of the total base rent a tenant will pay over the lease term or as a dollar per square foot per year figure, and may be due to a tenant rep, a landlord rep, or both.

The commission is typically earned or becomes payable on lease execution or a later milestone fixed in the listing agreement (see Payment Timing and Clawback Provisions below). It compensates the broker for sourcing the tenant, negotiating the terms, and managing the transaction through to signature. In a co-brokered deal where both a listing broker and a tenant rep broker are involved, the listing agreement between the landlord and the listing brokerage specifies the total commission, and in a common structure the listing brokerage agrees to share a portion of that commission with the cooperating tenant rep brokerage.

This structure differs from residential real estate, where compensation practices changed under the 2024 NAR settlement. In commercial leasing, rates and terms are negotiated in each listing agreement and move with market conditions, vacancy levels, and competition among landlords for tenants.

From the landlord's perspective, leasing commissions are a cost of doing business. Every lease expiration creates a potential commission event: either a renewal commission (if the tenant stays) or a new lease commission (if a replacement tenant must be found). The new lease commission is typically higher, which is one of the economic reasons landlords prefer renewals over tenant turnover. The commission cost, combined with tenant improvement allowances, downtime during vacancy, and free rent concessions, forms the total cost of leasing that institutional investors model when underwriting rollover risk.

As the Wikipedia overview of leasing commissions notes, the fee is typically calculated as a percentage of the total rent over the lease term or as a flat fee per square foot of leased space, with commission rates typically ranging from 3% to 6% of total lease value.

Commission Rate Ranges by Property Type and Market Tier

Leasing commission rates are not uniform. They vary across three dimensions: property type, market tier, and lease term. The ranges in this section and the rate tables are illustrative Apers assumptions, not survey data. The one published reference range cited here is 3% to 6% of total lease value (Wikipedia, linked above), and actual rates are negotiated in each listing agreement.

Office

Office leasing commissions are the highest among the major property types, reflecting the longer lease terms, larger transaction sizes, and more complex negotiations involved. In gateway markets (New York, San Francisco, Los Angeles, Chicago, Boston, Washington D.C.), the illustrative range is 4% to 6% of aggregate base rent over the lease term. In secondary markets (Denver, Nashville, Charlotte, Austin, Raleigh), the illustrative range compresses to 3% to 5%. In tertiary markets, it compresses further to 2.5% to 4%.

Higher percentage rates tend to apply to shorter leases or smaller transactions, where the absolute dollar commission would otherwise be insufficient to compensate the broker for time expended. Larger tenants with longer terms can command lower percentage rates because the aggregate rent base is large enough to generate a substantial commission at a lower rate. A 100,000 SF tenant signing a 10-year lease at $60/SF generates $60 million in aggregate rent. Even at 3%, the commission is $1.8 million.

Industrial

In the illustrative ranges, industrial commissions run lower than office, at 2% to 4% of aggregate rent for new leases. Lower per-square-foot rents and more standardized lease terms are common reasons. A 200,000 SF warehouse at $8/SF NNN on a 5-year term generates $8 million in aggregate rent. At 3%, the commission is $240,000. The dollar amounts are meaningful but the percentage rates are compressed relative to office.

Retail

Retail commissions vary based on the type of retail space. In the illustrative ranges, inline shop space carries a 4% to 6% commission in gateway markets (3% to 5% in secondary and tertiary markets), comparable to office, while anchor space runs lower at 2% to 4% in gateway markets (as low as 1.5% in tertiary markets) because the anchor tenant drives the deal and the landlord is often negotiating directly. Large-format retail is also one of the places where a flat dollar-per-square-foot structure is used instead of a percentage-of-rent formula.

Multifamily

Multifamily is the outlier. Individual apartment leases do not typically involve leasing commissions in the way that commercial leases do. However, master leases, corporate housing contracts, and build-to-rent portfolios may involve broker commissions structured similarly to commercial deals, either as a percentage of aggregate rent or a flat fee per unit, as negotiated.

These illustrative rates are for new leases. Renewal commissions are discussed in the section below. All percentages apply to aggregate base rent over the full lease term.

Three Calculation Methods

Leasing commissions can be calculated using three distinct methods. The choice of method depends on property type, market convention, and the terms of the listing agreement between the landlord and the brokerage. What follows is a practitioner's guide to all three methods with worked numbers.

Method 1: Percentage of Aggregate Rent

Per Wikipedia and Realized 1031, commissions are typically calculated as a percentage of aggregate rent. The commission is calculated as a fixed percentage of the total base rent over the full lease term. "Aggregate rent" means the sum of all base rent payments from lease commencement through lease expiration, excluding operating expense reimbursements, percentage rent, and other variable charges. The base itself is a negotiated term: some agreements calculate on gross rent, while others define a net figure, for example total rent due "less any Rent abated by Landlord" (see this net aggregate rent definition), and a commercial leasing attorney notes that free rent and similar items may be excluded when calculating commissions. The examples in this article calculate on gross rent with no abatement carve-out unless stated otherwise.

For a lease with rent escalations, the aggregate rent accounts for the escalation schedule. This is important because a 10-year lease at $50/SF with 3% annual bumps generates more aggregate rent than a flat $50/SF lease.

Some listing agreements use a declining commission rate that steps down over the lease term. Wikipedia describes a typical declining schedule as 6% on years one through five and 3% on years six through ten, reflecting the time value of money and the fact that the broker's work is concentrated at lease execution. The schedule below is a hypothetical (6% for the first year, 5% for years 2 through 5, and 4% for years 6 and beyond) applied to the same 10,000 SF office lease above.

The hypothetical schedule produces a higher total commission ($184,795 vs $153,249) because its blended rate is 4.82% of aggregate rent ($184,795 / $3,831,231), above the 4% flat comparator. A schedule whose blended rate falls below 4% would produce a lower total. Wikipedia's 6%/3% schedule, for example, would give $194,574 (5.08% blended) on this lease, so a step-down alone does not lower the commission. Whether the listing agreement uses a flat or declining rate is a negotiation point between the landlord and the listing brokerage.

Method 2: Dollars Per Square Foot Per Year

The PSF/year method sets the commission as a fixed dollar amount per square foot of leased space per year of the lease term. Wikipedia notes this structure is common for industrial and large-format retail leasing, in markets where lease rates are low per square foot but space sizes are large.

The PSF/year method is easy to calculate and compare across deals. It is indifferent to the actual rent, which can be an advantage or a disadvantage. In a market where rents vary from $6/SF to $12/SF NNN, the PSF commission normalizes the broker's compensation regardless of the rent achieved. Because the fee does not change with the rent achieved, the broker's compensation is not tied to pushing rent up or down.

A useful check is to translate a PSF/year rate into a percentage of rent so it can be compared with the percentage method. At the $6/SF to $12/SF NNN rents above, the 2% to 4% industrial range in this article equals $0.12 to $0.48 per SF per year (2% of $6 is $0.12; 4% of $12 is $0.48). A PSF/year rate well above that band implies a commission far above the percentage ranges in this article.

Method 3: Flat Fee

Flat-fee commissions are negotiated as a fixed dollar amount regardless of lease terms. This method can appear in several scenarios: very small spaces where percentage-based commissions would produce trivially small amounts, short-term leases where the aggregate rent does not support a percentage calculation, and sublease transactions where the sublessor wants cost certainty.

The structure is simple and predictable but does not scale with deal size, which is why it is less suited to institutional transactions.

New Lease vs Renewal Differentials

Renewal commissions are lower than new lease commissions. This is a common pattern in commercial real estate brokerage compensation. The reduction reflects the fact that a renewal requires less work: the tenant is already in place, the space does not need to be marketed, tours and proposals are unnecessary, and the negotiation is typically limited to rent and term adjustments on an existing relationship.

Wikipedia reports that renewal commissions commonly range from 1% to 3% of the renewal term's aggregate rent. In the illustrative ranges below, the renewal commission is 50% to about 63% of the new lease commission rate. If the new lease rate is 4% of aggregate rent, a renewal at 50% of that is 2%. Some listing agreements specify the renewal rate as a fixed percentage (e.g., "2% of aggregate renewal rent"). Others define it as a fraction of the new lease rate (e.g., "50% of the otherwise applicable commission"). The distinction matters when the new lease rate itself is on a declining schedule.

The renewal discount creates a powerful incentive in the landlord's rollover calculus. Consider a 20,000 SF office tenant whose lease expires in 18 months. If the tenant renews, the landlord pays a 2.5% renewal commission on $6.5 million of aggregate rent (20,000 SF x $65/SF x 5 years, before escalations), totaling $162,500. If the tenant vacates and a replacement tenant is found, the landlord pays a 5% new lease commission on the same aggregate rent, totaling $325,000. The commission differential alone is $162,500 before accounting for the far larger costs of tenant improvements, downtime, and free rent that accompany a new lease.

This differential is why institutional asset managers track renewal probability by tenant and model the commission spread in their rollover assumptions. The commission is often the smallest component of total leasing cost, but it is the most predictable and the easiest to budget for.

Why Renewals Pay Less

The lower renewal rate is economically rational from both the landlord's and the broker's perspective. For the landlord, a renewal involves less marketing cost, less uncertainty, and less physical buildout. The landlord is paying for a negotiation, not a search. For the broker, a renewal still represents meaningful compensation for advisory work, particularly when the tenant is considering relocation and the broker must present a competitive retention package. Even at a reduced rate, the renewal commission on the same rent base remains meaningful compensation for that advisory work.

Renewals also change who is paid. Wikipedia notes that in some transactions, particularly renewals and expansions by existing tenants, no tenant representative broker is involved and the listing broker retains the full commission. Lease and brokerage agreements frequently specify whether and at what rate a commission is payable when a renewal option is exercised.

Commission Flow: Co-Brokerage Splits, House Splits, and Overrides

The flow of leasing commission dollars from the landlord to the individual broker can involve multiple intermediaries and multiple splits. Figure 1 shows one common structure: the landlord pays the listing brokerage, which shares the fee with the tenant rep brokerage. Understanding this flow is important for analysts modeling landlord costs and for anyone evaluating brokerage economics from the broker's perspective.

The Co-Brokerage Split

The co-brokerage split (also called the cooperating commission or co-broke) is the portion of the total commission that the listing brokerage agrees to share with the tenant representation brokerage. Per Wikipedia, a standard split is 50/50, meaning the listing brokerage keeps half and pays half to the tenant rep brokerage, though splits of 60/40 or other ratios are common depending on the transaction. The split is specified in the listing agreement or a cooperating broker agreement. CREKB, discussing commission sharing between agents in general, says the split is commonly 50/50 but not always.

The 50/50 split is not universal. A listing agreement can set any ratio, including a split that favors the listing brokerage or an enhanced co-broke that favors the tenant rep brokerage as an incentive to show the space. When no tenant rep broker is involved, such as in some renewals and expansions, the listing broker retains the full commission.

House Splits and Brokerage Economics

The house split (also called the company dollar) is the portion of the broker's commission that the brokerage firm retains before paying the individual broker. This is distinct from a landlord-rep override, described below. The house split compensates the brokerage for providing the platform: office space, technology systems, research databases, marketing materials, insurance, licensing, and administrative support.

House splits vary by brokerage and by broker production. CREKB says that in small brokerages agents may start out at a 50/50 split and keep a larger percentage as they bring in more commission, with a 60/40 split described as typical, and that a split can follow a sliding scale that resets yearly. For larger brokerages organized in teams, it describes the agent keeping a smaller share (40% to 50% in its example, with a team manager receiving 20% to 30%). The 60/40 split used in this article is an illustrative assumption for a mid-career broker, and the 50/50 to 70/30 range used in Key Takeaways is likewise illustrative.

The Landlord-Rep Override

The fixed-total, split-the-fee model above is only one structure. In another, described in this Feldman Equities glossary, an outside tenant broker earns the full commission, and when the landlord has also hired its own broker, that broker is paid an override on top. In the glossary's example, the tenant broker gets 4% of aggregate rent, the landlord's broker gets a 50% override (another 2%), and the landlord's total cost is 6%. If the procuring broker is the same as the landlord's broker, the landlord pays only the 4%. In an override structure the landlord's total cost is not fixed, so the commission line in a pro forma should follow the listing agreement rather than assume a single pool that is divided between the two firms.

The Full Dollar Flow

Returning to the $153,249 gross commission on the 10,000 SF office lease at $50/SF NNN with 3% annual escalations over 7 years at a 4% flat rate (see the worked example below), and assuming the fixed-total structure in Figure 1 (all amounts rounded to the nearest dollar):

1. Landlord pays $153,249 to the listing brokerage per the listing agreement.
2. Listing brokerage retains $76,625 (50% co-broke split) and pays $76,625 to the tenant rep brokerage.
3. Listing brokerage retains $30,650 as its house share (40% of its $76,625 share) and pays $45,975 to the listing broker.
4. Tenant rep brokerage retains $30,650 as its house share (40% of its $76,625 share) and pays $45,975 to the tenant rep broker.

Total brokerage house revenue from the transaction: $61,300 ($30,650 per firm). Total individual broker compensation: $91,950 ($45,975 each). The landlord's $153,249 commission breaks down to 40% brokerage house revenue and 60% broker compensation (components sum to $153,250 because of rounding). In practice, the percentages vary by deal, by broker production, and by firm.

Payment Timing and Clawback Provisions

Leasing commissions may be paid in a single lump sum at lease execution or in installments timed to milestones in the lease lifecycle. The timing of actual cash outflows drives the cash flow model and the leasing cost budget in a property-level pro forma.

Common Payment Schedules

Published sources describe a range of structures. Realized 1031 says the full commission is typically payable at the start of a new lease, and a commercial leasing attorney writes that the commission is usually paid in one lump sum at the time of lease signing. Feldman Equities says it typically pays within 30 days of lease execution while noting that many other landlords pay 50 percent at signing and 50 percent after the tenant moves in. Wikipedia lists payment at lease execution, at rent commencement, or in installments split between the two. This article uses a two-installment structure as its example: half at lease execution (the date both parties sign the lease) and half at tenant occupancy or rent commencement, with the trigger for the second installment defined in the listing agreement. Some agreements tie it to the tenant opening for business, which can lag lease execution depending on the buildout required.

This split protects the landlord against paying the full commission on a lease that never results in actual occupancy. If the tenant signs the lease but never takes occupancy (due to business failure, construction delays, or simple default), the landlord has paid only half the commission. The second half is contingent on the tenant actually showing up.

Other structures exist. Some listing agreements pay 100% at lease execution. Others pay in tranches over the first several months of the lease, which spreads the landlord's cash outflow over a longer period.

Clawback Provisions

A clawback provision requires the broker to return all or part of the commission if the tenant defaults or vacates within a specified period after lease commencement. The clawback protects the landlord against paying a full commission on a lease that produces only a few months of rent before the tenant goes dark.

Clawback terms are negotiated, and this article does not rely on a market survey for them. As an illustrative declining scale (an assumption, not market data): if the tenant defaults within 6 months of rent commencement, the broker returns 100% of the commission; between 6 and 12 months, 50%; between 12 and 24 months, 25%; and after 24 months, the commission is fully earned and non-refundable.

From the broker's perspective, a clawback provision creates a contingent liability that persists for the clawback period after the deal closes. The exposure affects broker behavior: brokers with clawback liability have a financial incentive to ensure the tenant actually takes occupancy and pays rent, which aligns their interest with the landlord's.

Deferred Commission Structures

In distressed or high-vacancy markets, some landlords negotiate deferred commission structures where part or all of the commission is paid out of future rent receipts rather than at execution or occupancy. This approach conserves the landlord's upfront capital but increases the broker's risk. The broker is effectively financing the landlord's leasing cost.

Deferred commissions can be less attractive to brokerages that need near-term cash flow to fund operations. When they do appear, they may include a present-value adjustment or an interest component to compensate the broker for the time value of money. A $100,000 commission paid in 12 monthly installments of $8,333 starting at lease execution has a lower present value than $100,000 paid in full at execution, and the listing agreement should account for this.

How LC Is Modeled Below the Line

Leasing commissions are not operating expenses. They are capital costs that appear below the line in a property-level pro forma or DCF model. The classification affects how LC impacts NOI, cash flow, and valuation.

Above the Line vs Below the Line

In a standard property-level pro forma, the line that separates operating economics from capital economics is Net Operating Income (NOI). Everything above the line contributes to or detracts from NOI: rental revenue, vacancy loss, operating expenses, and management fees. Everything below the line sits between NOI and the equity cash flow: reserves, capital expenditures, tenant improvement allowances, leasing commissions, and debt service. (Treatment of reserves varies; they are commonly shown below NOI.)

Leasing commissions sit below the line because they are transaction costs associated with specific leasing events, not recurring operating expenses. A property with no lease expirations in a given year incurs zero leasing commissions. A property with five expirations might incur $500,000. The variability is driven by the lease rollover schedule, not by the ongoing operation of the building.

Amortized vs Expensed

Under GAAP (ASC 842), a commission paid by the landlord because the lease was signed is an initial direct cost. For an operating lease, the lessor defers initial direct costs at commencement and recognizes them over the lease term, on the same basis as lease income. They are not expensed in full in the period incurred. Assuming straight-line recognition, a $150,000 commission on a 10-year lease is recognized at $15,000 per year on the landlord's income statement, which smooths the P&L impact over the life of the lease.

In a cash flow model (DCF or waterfall), however, the full commission is modeled as a cash outflow in the period it is paid, regardless of the accounting amortization. The cash flow model cares about when the cash actually leaves the account. If the commission is paid 50% at execution and 50% at occupancy, the model shows two cash outflows in the periods those payments occur.

This difference between GAAP treatment and cash flow treatment is a common source of confusion for junior analysts. The income statement shows a smooth $15,000 annual amortization charge. The cash flow statement shows a lumpy $75,000 outflow in the execution quarter and another $75,000 in the occupancy quarter. Both are correct representations of the same economic event, viewed through different lenses.

Modeling LC in a DCF

In a hold-period DCF, leasing commissions are modeled as below-the-line cash outflows triggered by specific lease events. The model must capture three inputs for each lease: the commission rate, the aggregate rent base, and the payment timing. For a portfolio-level model with dozens or hundreds of leases, the commission assumptions are typically set as market-rate defaults that apply to all leases unless overridden at the individual lease level.

One common modeling approach for rollover scenarios is to assume a new lease commission at the market rate if the tenant vacates (weighted by the probability of non-renewal) and a renewal commission at a stated fraction of it if the tenant stays (weighted by the probability of renewal). The examples here use 50%, and the illustrative renewal table above runs from 50% to about 63%. The blended commission cost in any given period is a probability-weighted average of the two scenarios.

Total Leasing Cost at Rollover

Leasing commissions do not exist in isolation. When a lease expires, the landlord faces a bundle of costs that together constitute the total cost of leasing (sometimes called total leasing capital or rollover cost). The four components of total leasing cost are: tenant improvement allowance (TI), leasing commission (LC), downtime (vacancy loss during the gap between tenants), and free rent (abated rent offered as a concession to the new tenant).

The relative magnitude of these components varies by scenario. In a renewal, TI is typically lower (the space needs only cosmetic refreshment), LC is discounted (50% of new in this example), downtime is zero (the tenant stays in place), and free rent is minimal or absent. In a new lease, all four components are at full market levels. The spread between the renewal scenario and the new lease scenario is the economic penalty for tenant turnover.

On these illustrative assumptions, the total cost of replacing a 20,000 SF office tenant is about $2.5 million, compared to $462,500 for a renewal. The incremental cost of turnover is over $2 million, or roughly $100/SF. Leasing commissions account for $162,500 of that incremental cost, about 8% of the total. TI allowances ($900,000) and downtime ($650,000) are the dominant cost drivers.

The table calculates the commission on gross rent with no abatement carve-out. If the commission base were instead net of the 3 months of abated rent, the new lease base would be $6,500,000 - $325,000 = $6,175,000, the new lease commission would be 5.0% x $6,175,000 = $308,750, and the incremental commission cost would be $146,250 (about 7.2% of the $2,021,250 incremental total).

This context is why leasing commissions, while important, are often the smallest variable in the landlord's rollover calculus. The commission is predictable and relatively modest compared to the TI buildout and the lost rent during vacancy. Institutional investors focus most of their rollover analysis on TI budgets and downtime assumptions, with commissions treated as a known cost that follows directly from the rate schedule in the listing agreement.

For a deeper analysis of how TI allowances interact with leasing cost budgets, see Tenant Improvement Allowances and Market Standards.

Worked Example: Office Lease Commission Waterfall

This section walks through a complete commission calculation from lease terms to individual broker compensation. The example uses an illustrative Class A office lease in a secondary market.

Deal Parameters

• Property: 250,000 SF Class A office building, secondary market (illustrative).
• Tenant: Technology company, 10,000 SF, 7-year term.
• Base rent: $50.00/SF NNN, 3% annual escalations (illustrative assumption).
• Commission rate: 4% of aggregate base rent (flat rate per listing agreement).
• Co-brokerage split: 50/50 between listing brokerage and tenant rep brokerage.
• Broker/house split: 60/40 at both brokerages (illustrative assumption for a mid-career broker).
• Payment timing: 50% at lease execution, 50% at rent commencement (3 months post-execution).

Step 1: Calculate Aggregate Rent

Step 2: Calculate Gross Commission

Gross commission = 4% x $3,831,231 = $153,249 (exactly $153,249.24).

Step 3: Co-Brokerage Split

Listing brokerage retains: 50% x $153,249 = $76,624.62, rounded to $76,625.
Tenant rep brokerage receives: 50% x $153,249 = $76,624.62, rounded to $76,625.

Step 4: House Split and Broker Net

At each brokerage (60/40 split):
Individual broker receives: 60% x $76,625 = $45,975.
House share retained: 40% x $76,625 = $30,650.

Step 5: Payment Timing

Landlord cash outflow at lease execution: 50% x $153,249 = $76,625 (rounded).
Landlord cash outflow at rent commencement (3 months later): 50% x $153,249 = $76,625 (rounded).

What the Waterfall Reveals

First, the landlord's cost on a per-SF basis ($15.32/SF total, or $2.19/SF/year) is modest relative to the rent ($50/SF in Year 1) and far smaller than the $60/SF new-lease TI allowance assumed in the Total Leasing Cost table above. Leasing commissions are a real cost but they are rarely the dominant leasing expense.

Second, the individual broker nets less than one-third of what the landlord pays. Of every dollar the landlord spends on commissions, roughly 30 cents reaches each individual broker (assuming a 50/50 co-broke and 60/40 house split). The remaining 40 cents goes to the two brokerages' house share. This is the structural reality of the brokerage business and the reason that volume matters to individual brokers: each deal produces a modest payout, so consistent deal flow is essential.

Third, the payment timing matters for the landlord's cash flow model. In this example the $153,249 is not a single cash event. It is two payments of about $76,625, separated by the construction period. If the buildout takes 6 months instead of the 3 months assumed above, for example, the landlord's cash flow model should show the first payment in the execution month and the second payment 6 months later. Modeling the full commission as a single outflow in the execution month overstates the near-term cash drag and understates the outflow in the occupancy quarter.
