Rental broker commissions are typically calculated in one of two ways: as a percentage of the first year’s rent, usually between 10% and 15%, or as a flat amount equal to one month’s rent. Understanding how rental broker commissions are calculated matters because the same apartment can produce very different fees depending on which method the listing agreement uses, how long the lease runs, and, in a growing number of cities, who actually hired the broker.
Percentage of the Annual Rent
The most common calculation multiplies the monthly rent by twelve and then applies an agreed percentage. Residential brokerage agreements generally set that rate between 10% and 15% of first-year rent. A unit listed at $3,500 per month produces $42,000 in annual rent. At 15%, the broker earns $6,300. At 10%, the fee drops to $4,200.
Where the rate lands inside that range depends on leverage and difficulty. A landlord who routes dozens of units through one brokerage can often negotiate closer to 10%. A property that is hard to rent because of location, condition, or price tends to draw a higher rate, since the broker expects more showings and more marketing before a qualified tenant signs. Exclusive listings, where one broker works the property without competition, also tend to carry higher percentages.
One point worth knowing before you sign: commissions are almost always calculated on gross rent as written into the lease, not on the net effective rent after concessions. Offer a tenant one free month on a twelve-month lease and the broker’s commission is still based on twelve full months. Gross-rent calculation is the industry default even when the listing agreement doesn’t spell it out.
One Month’s Rent as the Fee
In many East Coast markets and other competitive urban rental markets, brokers charge one month’s rent as the commission. That works out to roughly 8.33% of annual rent, slightly below the percentage-based range, and the appeal is simplicity. The fee equals the number already on the lease.
For a lease at $2,800 per month, the commission is $2,800. Listing agreements state the fee as “one month’s rent” rather than a percentage, which avoids rounding disputes and keeps the closing ledger clean. Payment is usually due when the lease is signed. Some brokers require payment before lease execution, but collecting immediately after both parties sign is more common. Either way, the fee is a one-time cost tied to the initial lease, not a recurring charge on renewals unless the brokerage agreement says otherwise.
Multi-Year Leases and Graduated Rates
When a lease runs longer than twelve months, brokers usually adjust their compensation with graduated rates that decline each year. The reasoning is that the broker did most of the work to find and vet the tenant, and the later years reflect stability that the landlord benefits from without additional broker effort.
A common structure on a two-year residential lease:
- Year one: 10% of annual rent
- Year two: 5% of annual rent
On $30,000 in annual rent, that produces a $3,000 commission for year one and $1,500 for year two, totaling $4,500. Three-year and longer leases follow the same declining pattern, sometimes dropping to 2.5% or lower by the third year. These rates need to be in the brokerage agreement before marketing begins. Without explicit language covering each year, disputes over the total commission on longer leases are almost inevitable.
Flat Fee Arrangements
Some brokers charge a predetermined dollar amount that doesn’t move with the rent. A broker might quote $1,500 for finding a tenant and handling paperwork, and that number holds whether the unit rents for $1,200 or $1,800 per month.
Flat fees show up in two main scenarios. The first is limited-service listings, where the broker handles specific tasks such as posting the property on rental platforms and screening applicants but doesn’t manage the full leasing process. The second is lower-priced rentals where a percentage would not generate enough revenue to justify the broker’s time. On a $900 unit, a 10% annual commission produces only $1,080; a flat fee of $1,500 or $2,000 makes the transaction worthwhile for both sides. The flat fee is documented in a service agreement signed before marketing begins, which leaves less room to renegotiate but also fewer surprises.
Who Pays the Broker
Whether the landlord or tenant pays is one of the most market-dependent questions in residential real estate. There is no federal rule assigning the cost to either side. Local custom and market conditions have historically decided it.
In many Northeast cities, tenants have traditionally paid the broker fee on top of the security deposit and first month’s rent, sometimes producing five figures in upfront cash just to move in. In other regions, landlords pay the commission as a cost of doing business and price it into rent.
That landscape is changing. New York City’s Fairness in Apartment Rental Expenses (FARE) Act, which took effect in June 2025, requires that the party who hires the broker pays the fee. Because landlords and property managers hire listing brokers in most transactions, tenants in NYC generally no longer owe a broker fee unless they independently hire their own broker. Massachusetts enacted a similar rule effective August 2025, preventing brokers from collecting fees from tenants unless the tenant hired the broker directly.
Even where these laws don’t apply, the brokerage agreement should state who is responsible for the commission, and disclosure of the paying party to everyone in the transaction before signing is a near-universal requirement across states.
What Happens if the Tenant Breaks the Lease
A broker’s commission is generally considered earned at lease execution. That means the broker keeps the fee even if the tenant moves out early. The listing agreement controls. Most broker-drafted agreements state that the commission is “deemed earned upon lease execution,” leaving no obligation to return any portion if things fall apart later.
Some agreements use different trigger language, tying payment to tenant occupancy rather than lease signing. Under those terms, a tenant who signs but never moves in could create a situation where the commission was never technically payable. The distinction is worth reading for before signing.
Clawback provisions, where the broker returns part of the commission if the tenant leaves early, are uncommon but not unheard of. When they appear, they typically prorate: on a broken twelve-month lease after three months, the broker returns roughly three-quarters of the fee. These provisions almost always sunset partway through the lease term, often at the six-month mark, after which the broker owes nothing back. Clawbacks rarely carry into renewals.
A separate issue sometimes appears in the lease itself: a clause requiring the departing tenant to reimburse the landlord for the broker fee on an early break. That is a landlord-tenant matter, not a broker-tenant one, and enforceability varies by jurisdiction.
Tax Treatment for Landlords
Landlords who pay a broker commission to find a tenant can generally deduct that cost as a rental expense. The IRS lists commissions among the ordinary expenses of managing rental property and allows landlords to deduct rental expenses in the year they are paid.1Internal Revenue Service. Publication 527 (2025), Residential Rental Property For a standard one-year lease with a lump-sum commission at signing, the full amount is deductible in that tax year.
Multi-year leases work differently. A large upfront commission covering a lease that spans several years may need to be spread over the life of the lease rather than claimed all at once. The general principle is that costs tied to acquiring a lease are amortized over the lease term.2Office of the Law Revision Counsel. 26 US Code 178 – Amortization of Cost of Acquiring a Lease On a two-year lease with a $4,500 commission, that means deducting $2,250 per year rather than $4,500 in year one. A tax professional can confirm the correct treatment, especially where renewal options affect the amortization period.
Tenants who pay broker fees cannot deduct them on personal returns. The IRS does not treat a tenant’s cost of securing a place to live as a deductible expense, even when the fee is substantial.
