Commercial Lease Commission Calculator
A commercial lease commission is a percentage of the total base rent over the lease term, not a percentage of one year's rent. Multiply rentable square feet by rent per square foot to get annual rent, apply the commission rate for each year, and add the years together. Rates are negotiated and usually run 4% to 6% on a declining schedule such as 6-5-4-3-3%. On a 10,000 SF office lease at $30 per square foot over five years, that is $63,000. Roughly half is typically paid at lease execution and the rest at occupancy.
What are lease commissions?
A lease commission, also called a leasing commission or LC, is the fee paid to the brokers who put a lease together. It is earned when the lease is signed and it is calculated off the rent the tenant has committed to pay, which is why a longer term and a higher rent both produce a larger commission from the same square footage.
On the ownership side the same number shows up as a capital cost. Landlords and lenders underwrite leasing commissions alongside tenant improvement dollars as the TI/LC line, the cash an owner has to spend to fill a space. That is worth knowing when you negotiate, because the landlord is weighing your commission against the free rent and build-out allowance in the same budget.
Two things separate a lease commission from a sales commission. A sale pays one percentage on one purchase price at one closing. A lease pays a schedule of percentages across a stream of future rent, and it usually pays in two installments months apart. That timing is the whole problem for most brokers, and it is covered in when commercial leasing brokers actually get paid.
The commission formula
Every commission calculation, in leasing or anywhere else, is the same one line: the base amount multiplied by the rate expressed as a decimal. What makes commercial leasing different is that the base amount is a multi-year rent stream and the rate usually changes each year.
Annual rent = Rentable SF × Rent per SF
Year commission = Annual rent × (Year rate ÷ 100)
Total commission = Sum of all year commissions
With a single flat rate the whole thing collapses to: Total lease value × (Rate ÷ 100).
Worked example: flat rent, declining schedule
Take a 10,000 SF office lease at $30 per square foot on a five-year term with a 6-5-4-3-3 schedule. Annual rent is $300,000 and total lease value is $1,500,000. Apply the schedule year by year and the commission comes to $63,000, which is a blended rate of 4.2% on the deal.
| Year | Annual rent | Rate | Commission |
|---|---|---|---|
| 1 | $300,000 | 6% | $18,000 |
| 2 | $300,000 | 5% | $15,000 |
| 3 | $300,000 | 4% | $12,000 |
| 4 | $300,000 | 3% | $9,000 |
| 5 | $300,000 | 3% | $9,000 |
| Total | $1,500,000 | 4.2% blended | $63,000 |
A flat 4% on the same deal pays $60,000 and a flat 5% pays $75,000, so the schedule matters as much as the headline rate. Anyone quoting you "6%" on a lease is almost certainly quoting the year-one tier, not the blended rate you will actually be paid.
Worked example: with annual escalations
Most leases escalate. Add 3% annual bumps to the same deal and the rent stream grows to about $1,592,700 over five years, which lifts the same 6-5-4-3-3 schedule to roughly $66,100. That is about $3,100 more than the flat-rent version, from a clause that is easy to skip when you are estimating in your head. Enter the escalation in the calculator above and it compounds the rent for you.
Worked example: a ten-year lease
Longer terms are where the useful shortcut lives. On a ten-year deal with a typical declining schedule of 6-5-4-3-3-3-2.5-2.5-2-2, the percentages sum to 33%. On the same $300,000 annual rent that is a $99,000 commission, a 3.3% blended rate on $3,000,000 of lease value. A full commission on a ten-year lease usually lands somewhere near one third of the first year's rent, which is a fast sanity check before you run the real numbers.
Quick commission math: common percentages
If you just need the arithmetic, move the decimal point two places left and multiply. Six percent of $300,000 is $18,000. The table covers the calculations brokers look up most often, with the context each one usually comes from in a leasing deal.
| Calculation | Math | Result | Where it shows up |
|---|---|---|---|
| 6% of $300,000 | 300,000 × 0.06 | $18,000 | Year-one commission on a 10,000 SF lease at $30/SF |
| 5% of $200,000 | 200,000 × 0.05 | $10,000 | Year-two tier on a $200,000 annual rent |
| 4% of $1,000,000 | 1,000,000 × 0.04 | $40,000 | Flat rate on a $1M total lease value |
| 3% of $500,000 | 500,000 × 0.03 | $15,000 | Back-year tier on a large annual rent |
| 2% of $300,000 | 300,000 × 0.02 | $6,000 | Renewal or late-year tier |
| 5% of $10,000 | 10,000 × 0.05 | $500 | Small suite, storage or short-term deal |
| 10% of $50,000 | 50,000 × 0.10 | $5,000 | Short-term or small-dollar deal quoted on one year |
| 15% of $50,000 | 50,000 × 0.15 | $7,500 | Residential rental convention, not commercial |
The trap: "6% commission on $300,000" is only $18,000 if $300,000 is the amount the 6% actually applies to. In commercial leasing the percentage applies to a year of rent inside a schedule, or to the total lease value, depending on how the agreement is written. Confirm the base before you agree to a rate, because the same percentage can mean a five-fold difference in dollars.
Which rent the percentage applies to
The base is negotiated and it is the single most common source of disputes on a commission statement. Most agreements calculate on net or base rent only and exclude the pass-throughs, so operating expense escalations, CAM, real estate taxes, insurance, percentage rent in retail, parking income and any amortized tenant improvement dollars are stripped out before the rate is applied. In a full-service gross lease the base may instead be the gross rent, which is a materially larger number on the same deal. Read the definition clause rather than assuming.
Face rent versus effective rent is the other lever. Face rent is the headline number in the lease. Effective rent nets out free rent and concessions. On a five-year, 10,000 SF deal at $30 per square foot with six months free, face value is $1,500,000 and effective value is $1,350,000. At a flat 4% that is $60,000 versus $54,000, a $6,000 swing on one clause. Use the effective rent option in the calculator when your commission agreement is written that way.
How to use this calculator
Enter the leased area in rentable square feet, the base rent per square foot, and the lease term in years. Set your commission rate, either as a single flat percentage or as a declining schedule using the year-by-year fields. Add an annual escalation if the lease has one. If your deal is priced on effective rent rather than face rent, use the effective rent option so free-rent periods and concessions are reflected before the commission is calculated.
The result is the total gross commission on the transaction, before it is split with any co-broker or with your brokerage. To see what you actually keep after those deductions, use the net payout calculator. For the full derivation of the math, see the guide on how to calculate a commercial leasing commission.
Typical commission rates by asset class
There is no legally fixed commission rate anywhere in the United States. Rates are negotiated deal by deal and they move with asset class, market, deal size and how much work the assignment takes. Large blocks of space and long terms tend to price lower per dollar of rent, because the absolute commission is already substantial. The ranges below are what brokers commonly see, not a schedule you are entitled to.
| Asset class | Common structure | Typical blended rate |
|---|---|---|
| Office | Declining schedule, often 6-5-4-3-3 or similar | 3% to 4.5% |
| Industrial and warehouse | Declining schedule, or flat 4% to 5% on shorter terms | 3% to 5% |
| Retail | Often flat 4% to 6% on total base rent, percentage rent excluded | 4% to 6% |
| Medical office | Priced like office, sometimes higher on small suites | 3% to 5% |
| Flex and R&D | Priced like industrial | 3% to 5% |
| Ground lease | Low percentage on a very long rent stream, often capped | 1% to 3% |
| Renewal or extension | Commonly half the new-deal rate, sometimes a flat 2% to 3% | 1.5% to 3% |
What drives the rate within those ranges, and how to argue for the top of the band, is covered in the guide on typical commercial lease commission rates.
Commission value by US market
The same square footage is worth very different commissions depending on the market, because the commission tracks the rent. A 10,000 SF lease in Manhattan, where office asking rents run far above the national average, produces a much larger commission than the identical footprint in a secondary metro. The heatmap above estimates total commission value across major US markets so you can see where the dollars concentrate.
Market estimates are anchored to published average asking rents from sources such as CBRE, JLL, and Cushman & Wakefield. Asking rents are illustrative, not signed or effective rents, so treat the map as a directional comparison rather than a quote on a specific deal.
The NYC standard
New York is the market brokers ask about most, and it has the strongest convention, though still no fixed rate. Manhattan office leases are typically commissioned on aggregate rent over the term using a declining schedule that starts near 5% to 6% in year one and steps down toward 2% to 2.5% in the later years. On a ten-year deal the schedule commonly totals somewhere close to a third of the first year's annual rent, which is why New York brokers often quote a "full commission" as a multiple of year-one rent rather than as a percentage.
The landlord pays, and the commission is usually split between the landlord's agent and the tenant's representative. Because Manhattan asking rents are among the highest in the country, the same 10,000 SF requirement generates a commission several times larger than in most secondary markets, and the payment schedule stretches accordingly.
One warning on the number 15%. In New York residential rentals a broker fee of 12% to 15% of annual rent is a normal convention. That has nothing to do with commercial leasing, where a 15% rate on total lease value would be far outside any market. If you see a double-digit percentage quoted on a commercial deal, check whether it is being applied to one year of rent or to the whole term.
Who pays the commission, and when
In most commercial leasing deals the landlord pays the commission, even when you represented the tenant. The commission agreement names the payor and sets the schedule. The catch is timing: a leasing commission usually does not pay all at once. It commonly splits in half, with the first part triggered at lease execution and the second part triggered later, most often when the tenant takes occupancy after a build-out.
That second trigger is where brokers get stuck, because occupancy waits on tenant improvement work you do not control. The mechanics of that split are covered in the guide on the 50/50 trap, and the way TI work delays the back half is in the guide on TI allowance and commission timing.
Splits, renewals and clawbacks
The number this calculator produces is the gross commission on the transaction, and very little of it reaches your bank account intact. It is first split between the listing side and the procuring side, commonly close to half and half in leasing. Your brokerage then takes its share of your side, anywhere from a small desk fee arrangement to a 50/50 split depending on your agreement and seniority. A $63,000 gross commission can easily be $15,000 to $20,000 in your pocket. Run your actual splits through the net payout calculator before you spend it.
Renewals, expansions and options need to be handled in the original agreement or they quietly disappear. Expansions into additional space usually pay at the full new-deal rate on the added square footage. Renewals and extensions typically pay at a reduced rate, often half. Options that the tenant exercises without broker involvement are frequently excluded entirely unless you wrote yourself in, so the clause to negotiate is the one covering future terms, not the headline rate.
Finally, check for a clawback. Many commission agreements let the landlord recover or offset a paid commission if the tenant defaults or the lease is terminated within a defined early window. It is a real exposure on a deal with a thin covenant, and it is worth reading before you count the money as yours.
Turning an earned commission into cash now
Once you know what a commission is worth, the next question is whether you want to wait months for the back half. A commission advance lets you convert an earned but unpaid commission into cash now, rather than waiting on an occupancy date set by a contractor's schedule. Cash For Commish purchases future commission payments at a flat 3⅓% discount for each month outstanding, with no underwriting or origination fees, no personal guarantee, and funding the next business day. It is not a loan; you are selling an asset, not taking on debt.
To weigh an advance against borrowing, use the advance vs loan calculator, or read the pillar guide on commission advances for commercial leasing brokers.
Frequently asked questions
Calculating the commission
How do you calculate commission on a lease?
Multiply rentable square footage by rent per square foot to get annual rent, apply the commission rate for each year of the term, and add the years together. A 10,000 SF lease at $30 per square foot on a five-year term with a 6-5-4-3-3 schedule pays $63,000. With a single flat rate you can shortcut it to total lease value multiplied by the rate.
What is the formula for calculating commission?
Commission equals the base amount multiplied by the rate divided by 100. In leasing the base amount is the rent stream, so the full formula is: rentable SF times rent per SF gives annual rent, annual rent times each year's rate gives that year's commission, and the years added together give the total.
How does a declining commission schedule work?
The rate steps down over the term because the early years are worth more to the landlord. A 6-5-4-3-3 schedule applies 6% to year one rent, 5% to year two, and so on, then totals the result. The calculator handles this automatically when you enter year-by-year rates.
Is commission calculated on total lease value or first year rent?
On total lease value in almost all US commercial leasing, applied year by year through a declining schedule. Some markets quote the result as a multiple of first-year rent as shorthand, but the calculation itself runs across the whole term. Always confirm which base your agreement uses, because the difference is several times the dollars.
Is the commission based on gross rent or base rent?
Usually base or net rent only. CAM, operating expense escalations, real estate taxes, insurance, parking income, percentage rent and amortized TI are normally excluded. In a full-service gross lease the agreement may use gross rent instead, which produces a noticeably larger commission on the same deal, so the definition clause is worth reading closely.
How do you calculate commission on a lease with free rent?
It depends on whether the agreement uses face rent or effective rent. Face rent ignores the concession. Effective rent subtracts it first. On a five-year, 10,000 SF deal at $30 per square foot with six months free, the base drops from $1,500,000 to $1,350,000, which at a flat 4% is the difference between $60,000 and $54,000.
How do lease escalations affect the commission?
They increase it, because the commission tracks the actual rent in each year. Adding 3% annual bumps to a $300,000 starting rent over five years lifts the rent stream to about $1,592,700 and raises a 6-5-4-3-3 commission from $63,000 to roughly $66,100.
What is a commission on a 10-year lease worth?
A typical ten-year declining schedule such as 6-5-4-3-3-3-2.5-2.5-2-2 sums to 33% of one year's rent. On a $300,000 annual rent that is $99,000, a blended 3.3% on $3,000,000 of lease value. As a rough check, a full ten-year commission usually lands near one third of the first year's rent.
Quick percentage math
What is 6% commission on $300,000?
$18,000. Multiply 300,000 by 0.06. In a leasing context this is typically the year-one tier on a 10,000 SF lease at $30 per square foot, not the whole commission. Across a full five-year 6-5-4-3-3 schedule the same deal pays $63,000.
What is 5% commission on $200,000?
$10,000. Multiply 200,000 by 0.05.
What is 5% commission on $10,000?
$500. Multiply 10,000 by 0.05.
What is 3% commission on $500,000?
$15,000. Multiply 500,000 by 0.03.
What counts as a normal rate
What is a typical commission rate on a commercial lease?
Rates are negotiated and vary by market, asset class and deal size, but commercial leasing commissions commonly fall in the 4% to 6% range on a declining schedule, which blends out to roughly 3% to 4.5% across the term. There is no legally fixed rate anywhere in the United States.
What is a reasonable commission percentage?
For a standard commercial lease, a declining schedule in the 4% to 6% band is normal and defensible. Judge it on the blended rate across the term rather than the year-one number, and expect large blocks of space, long terms and renewals to price below that band.
Is 2% a good commission on a commercial lease?
It is at the low end. Two percent is normal as a back-year tier inside a declining schedule, on a renewal, on a very large block of space, or on a ground lease. As a single flat rate on a standard office or industrial deal it is below market and worth pushing back on.
Is 3% commission a lot?
No. Three percent is close to the typical blended rate on a commercial lease once a declining schedule is averaged across the term, and it appears routinely as a later-year tier. It only looks low next to a year-one rate of 6%, which is a different number measured on a different base.
Is 10% commission a lot on a lease?
On total lease value, yes, well above any commercial market. A double-digit percentage almost always means the rate is being applied to one year of rent rather than the full term, or that it is a small short-term deal where a flat fee would otherwise be uneconomic. Check the base before comparing it to anything.
Is 15% commission a lot?
In commercial leasing on total lease value, far above market. In residential rentals, particularly New York City, a fee of 12% to 15% of one year's rent is a standard convention. The two are not comparable because the base is completely different.
What is the standard commission for a commercial lease in NYC?
There is no fixed standard, but Manhattan office leases commonly use a declining schedule on aggregate rent starting near 5% to 6% in year one and stepping down toward 2% to 2.5% in later years. On a ten-year deal that typically totals close to a third of the first year's annual rent. The landlord pays, and the fee is usually split between the landlord's agent and the tenant's representative.
Getting paid
Who pays the leasing commission?
In most commercial leases the landlord pays, even when you represented the tenant. The commission agreement names the payor and sets the payment schedule.
When does the commission actually get paid?
Usually in two parts: roughly half at lease execution and half at occupancy. The occupancy half can lag by months while tenant improvement work is completed. A commission advance can close that gap.
How is the commission split between brokers?
The gross commission is typically divided between the listing side and the procuring side, often close to half and half in leasing, and each broker's share is then split with their brokerage. A $63,000 gross commission frequently nets an individual broker $15,000 to $20,000 depending on the co-broke and the house split.
Do you get paid commission on a lease renewal?
Only if the original agreement says so. Renewals and extensions commonly pay at a reduced rate, often half the new-deal rate or a flat 2% to 3%, and options exercised without broker involvement are frequently excluded altogether. Negotiate the future-term language when the deal is signed, not when the renewal comes up.
Can the landlord take the commission back if the tenant defaults?
Many commission agreements include a clawback or offset provision allowing recovery if the tenant defaults or the lease terminates within a defined early period. It is a real risk on deals with weak credit tenants, so read the recapture clause before treating the money as final.
Can I get paid before the tenant takes occupancy?
Not from the landlord, whose obligation is tied to the occupancy trigger in the commission agreement. A commission advance is the alternative: you sell the earned but unpaid portion and receive cash now. Cash For Commish prices this at a flat 3⅓% for each month outstanding with no fees and no personal guarantee.
Are lease commissions taxable?
Yes. Most brokers are independent contractors, so commission income is ordinary income reported on a 1099 and subject to self-employment tax, with nothing withheld at source. Set aside for it as commissions land and confirm your specific treatment with a CPA.
Related deal costs
How much are legal fees for a commercial lease?
For a straightforward lease, attorney review commonly runs from about $1,500 to $5,000, with hourly rates typically between $250 and $700 depending on the market. Large, heavily negotiated or multi-site deals run well above that. Legal fees are a cost to the landlord or tenant and are not deducted from the broker commission, though some leases require the tenant to reimburse the landlord's costs.
What is the difference between a leasing commission and a sales commission?
A sales commission is one percentage applied to one purchase price and paid at closing. A leasing commission is a schedule of percentages applied to a multi-year rent stream, usually paid in two installments months apart. That is why leasing brokers face a cash flow gap that sales brokers generally do not.
