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. In nearly all institutional transactions, the landlord pays the commission. This is true regardless of which side the broker represents. The listing broker (who represents the landlord) and the tenant representation broker (who represents the tenant) both receive their compensation from the landlord's funds. The tenant 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 commission is earned when the lease is executed. 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 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 commission structures were altered by the 2024 NAR settlement. Commercial leasing commissions have remained stable in structure for decades, though the rates themselves fluctuate with market conditions, vacancy levels, and competition among landlords for credit 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 almost always 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 a percentage of the total rent over the lease term, though the specifics vary by market, asset type, and negotiation.

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.

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.), new lease commissions typically run 4% to 6% of aggregate base rent over the lease term. In secondary markets (Denver, Nashville, Charlotte, Austin, Raleigh), the range compresses to 3% to 5%. In tertiary markets, commissions may be as low as 2.5% to 4%.

The higher end of the range applies to smaller tenants (under 10,000 SF) and shorter terms (3 to 5 years), where the commission as a percentage of rent must be higher to generate a meaningful dollar amount for the broker. Larger tenants (50,000+ SF) with longer terms (10+ years) 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

Industrial commissions run lower than office, typically 2% to 4% of aggregate rent for new leases. The lower rates reflect shorter average negotiation cycles, more standardized lease terms, and lower per-square-foot rents. 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.

In hot industrial markets where vacancy rates have dropped below 3%, commission rates have compressed further as landlords face less competition for tenants. When every warehouse in a submarket is spoken for, the listing broker's job is easier and the landlord's willingness to pay a premium commission declines.

Retail

Retail commissions vary widely based on the type of retail space. Inline shop space in a grocery-anchored center might carry a 4% to 6% commission, comparable to office. Anchor space (big-box, 20,000+ SF) commands lower rates, typically 2% to 4%, because the anchor tenant drives the deal and the landlord is often negotiating directly. Pad sites and outparcels often use flat-fee or PSF structures rather than percentage-of-rent formulas.

Specialty retail (restaurants, entertainment, experiential tenants) can push commissions higher, particularly in urban mixed-use developments where the tenant mix is curated and the landlord values the broker's ability to source a specific type of operator.

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, usually at 2% to 3% of aggregate rent or a flat fee per unit.

These 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. Adventures in CRE's leasing commission glossary provides a concise definition of the core formula. What follows is the institutional practitioner's guide to all three methods with worked numbers.

Method 1: Percentage of Aggregate Rent

This is the dominant method in institutional leasing. 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.

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. A common structure is 6% for the first year, 5% for years 2 through 5, and 4% for years 6 and beyond. This declining structure reflects the idea that early-term rent is more certain (and therefore more valuable to the broker) than later-term rent, which carries higher rollover risk. Using the same 10,000 SF office lease above, a declining rate schedule produces a different total.

The declining rate schedule produces a higher total commission ($184,795 vs $153,249) because the early-year rates are elevated. 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. This method is most common in industrial leasing and in markets where simplicity is preferred over precision.

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. Some landlords prefer this because it removes any incentive for the broker to negotiate lower rents to close a deal faster.

Typical PSF/year rates for industrial leasing range from $0.50 to $1.50 depending on market and deal size. Office deals that use this method (less common) tend to range from $1.50 to $3.00 per SF per year.

Method 3: Flat Fee

Flat-fee commissions are negotiated as a fixed dollar amount regardless of lease terms. This method appears in three scenarios: very small spaces (under 2,000 SF) where percentage-based commissions would produce trivially small amounts, short-term leases (1 to 2 years) where the aggregate rent does not support a percentage calculation, and sublease transactions where the sublessor wants cost certainty.

Flat fees for small commercial spaces typically range from $2,000 to $10,000. For medium-sized sublease transactions, they can run $15,000 to $50,000. The structure is simple and predictable but does not scale with deal size, which is why it is uncommon in institutional transactions.

New Lease vs Renewal Differentials

Renewal commissions are lower than new lease commissions. This is one of the most consistent patterns 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.

The typical renewal commission is 50% to 75% of the new lease commission rate. If the new lease rate is 4% of aggregate rent, the renewal rate is 2% to 3%. 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 $1.2 million of aggregate rent (5 years at $60/SF with escalations), totaling $30,000. If the tenant vacates and a replacement tenant is found, the landlord pays a 5% new lease commission on the same aggregate rent, totaling $60,000. The commission differential alone is $30,000 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. The broker's time investment on a renewal is typically 20% to 40% of a new lease transaction, so a 50% commission rate on the same rent base still produces an attractive hourly return.

Some listing agreements eliminate the renewal commission entirely, particularly for anchor tenants in retail. In these situations, the landlord handles the renewal negotiation internally and does not involve a broker. This is more common when the landlord has an in-house leasing team with the capacity to manage the renewal directly.

Commission Flow: Splits, Overrides, and Brokerage Economics

The flow of leasing commission dollars from the landlord to the individual broker involves multiple intermediaries and multiple splits. 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. The standard split is 50/50, meaning the listing brokerage keeps half and pays half to the tenant rep brokerage. This split is specified in the listing agreement and is communicated to cooperating brokers through the market's commercial listing service or through direct broker-to-broker communication.

The 50/50 split is not universal. Some listing agreements specify 60/40 in favor of the listing brokerage, particularly in markets where the listing broker's marketing costs are high or where the landlord's property is difficult to lease. Conversely, some landlords offer enhanced co-broke splits (55/45 or 60/40 in favor of the tenant rep) to incentivize tenant rep brokers to show their space. In a high-vacancy submarket, an above-market co-broke split is one of the tools a landlord uses to attract broker attention.

Override Commissions and Brokerage House Economics

The override (also called the house split, desk fee, or company dollar) is the portion of the broker's commission that the brokerage firm retains before paying the individual broker. The override compensates the brokerage for providing the platform: office space, technology systems, research databases, marketing materials, insurance, licensing, and administrative support.

Override structures vary by brokerage and by broker seniority. A junior broker at a major national firm (CBRE, JLL, Cushman and Wakefield, Newmark) might be on a 50/50 split with their firm, meaning the firm keeps 50% of the broker's side of every deal. A senior broker or top producer might negotiate a 70/30 or even 80/20 split in their favor. The most productive brokers can negotiate down to a 90/10 split or a flat monthly desk fee with 100% commission retention above the fee.

As Realized 1031's leasing commission glossary explains, the commission formula and payment structure can vary by market. What the glossaries typically omit is the override layer, which is the mechanism by which brokerage firms generate their revenue. Understanding override economics is essential for anyone evaluating the brokerage business model or analyzing why commission rates in a market are sticky even when vacancy declines.

The Full Dollar Flow

Returning to the $140,000 gross commission on a 10,000 SF office lease at $50/SF NNN for 7 years at a 4% flat rate:

1. Landlord pays $140,000 to the listing brokerage per the listing agreement.
2. Listing brokerage retains $70,000 (50% co-broke split) and pays $70,000 to the tenant rep brokerage.
3. Listing brokerage retains $28,000 as house override (40% of its $70,000 share) and pays $42,000 to the listing broker.
4. Tenant rep brokerage retains $28,000 as house override (40% of its $70,000 share) and pays $42,000 to the tenant rep broker.

Total brokerage house revenue from the transaction: $56,000 ($28,000 per firm). Total individual broker compensation: $84,000 ($42,000 each). The landlord's $140,000 commission breaks down to 40% brokerage overhead and 60% broker compensation. In practice, the percentages vary by deal, by broker seniority, and by firm, but the architecture is consistent.

Payment Timing and Clawback Provisions

Leasing commissions are not always paid in a single lump sum at lease execution. The most common payment structure splits the commission into two 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.

Standard Payment Schedule

The institutional standard is a two-installment structure. Half of the commission is paid at lease execution (the date both parties sign the lease), and the other half is paid at tenant occupancy or rent commencement (whichever occurs first). Some listing agreements tie the second installment to the tenant opening for business, which can lag lease execution by 3 to 12 months 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.

Alternative payment structures exist. Some listing agreements pay 100% at lease execution. This is more common with smaller landlords, shorter lease terms, and retail leases where occupancy follows execution quickly. Other agreements pay one-third at execution, one-third at occupancy, and one-third at the first anniversary of the lease, spreading 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.

Typical clawback structures operate on a declining scale. If the tenant defaults within 6 months of rent commencement, the broker returns 100% of the commission. If the tenant defaults between 6 and 12 months, the broker returns 50%. If the tenant defaults between 12 and 24 months, the broker returns 25%. After 24 months, the commission is fully earned and non-refundable.

Clawback provisions are more common in listing agreements for credit-sensitive space: Class B and C office, inline retail with small tenants, and flex/industrial space leased to startups or early-stage companies. Class A office leases with investment-grade tenants rarely include clawback provisions because the default risk is low enough that the landlord does not require the protection.

From the broker's perspective, clawback provisions create a contingent liability that persists for 12 to 24 months after the deal closes. Brokerages typically hold clawback reserves on their balance sheet to cover potential returns. The clawback 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 are uncommon in institutional transactions because brokerages need near-term cash flow to fund operations. When they do appear, they typically 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, management fees, and reserves. Everything below the line sits between NOI and the equity cash flow: debt service, capital expenditures, tenant improvement allowances, and leasing commissions.

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), leasing commissions paid by the landlord are capitalized and amortized over the lease term. They are not expensed in full in the period incurred. A $150,000 commission on a 10-year lease is amortized 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.

The standard modeling approach for rollover scenarios is to assume a new lease commission at 100% of the market rate if the tenant vacates (weighted by the probability of non-renewal) and a renewal commission at 50% of the market rate if the tenant stays (weighted by the probability of renewal). 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), 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.

The total cost of replacing a 20,000 SF office tenant in a gateway market exceeds $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.

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 ContractsCounsel's explainer on standard commercial lease commissions, which includes legal context on how these costs are documented in lease and brokerage agreements.

Worked Example: Office Lease Commission Waterfall

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

Deal Parameters

• Property: 250,000 SF Class A office building, secondary market (Denver metro).
• Tenant: Technology company, 10,000 SF, 7-year term.
• Base rent: $50.00/SF NNN, 3% annual escalations.
• 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 (assumed 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.

Step 3: Co-Brokerage Split

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

Step 4: House Override and Broker Net

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

Step 5: Payment Timing

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

What the Waterfall Reveals

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 a typical TI allowance ($40 to $70/SF for new office buildout). 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 brokerage house overhead. 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. The $153,249 is not a single cash event. It is two payments of $76,625, separated by the construction period. If the buildout takes 6 months, 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.
