I think 10% is fair. I know that is not what a lot of sellers want to hear when they are about to part with a significant chunk of their sale proceeds, but after doing this for as long as I have, I can tell you that a good broker earns every dollar of that commission and then some. The problem is not the percentage. The problem is that too many sellers sign listing agreements without understanding what the fee covers, how it is structured, and what they should be negotiating before the ink dries.
Business broker fees are the commissions and related charges a broker earns for facilitating the sale of a business. For small businesses valued under $1 million, commissions typically run 8% to 12% of the final sale price, with 10% functioning as the industry standard. For larger businesses in the $1 million to $5 million range, tiered formulas like the Double Lehman bring the blended rate down to 6% to 9%. For deals above $5 million, rates drop further to 4% to 8%, and for transactions above $25 million handled by M&A advisory firms, success fees typically land between 1% and 4%. The seller pays the full commission at closing in nearly every transaction. That is how this industry works, and anyone who tells you otherwise either does not know or is not being straight with you.
The Short Version
The standard business broker commission for Main Street businesses (under $1M sale price) is 10% of the final sale price, with the typical range running 8% to 12%.
For larger deals ($1M to $5M), most brokers use the Double Lehman formula (10-8-6-4-2 by million-dollar tier), producing blended rates of 6% to 9%.
The seller pays the entire commission at closing in nearly all transactions; if the deal does not close, no success fee is owed.
Commission covers valuation, CIM preparation, marketing, buyer screening, negotiation management, due diligence support, and confidentiality protection throughout the process.
Commissions are negotiable, especially for larger, well-documented businesses, but cutting the rate too aggressively can reduce the broker's motivation and the quality of service you receive.
Standard Commission Rates by Deal Size
The single biggest factor that determines what a broker charges is the size of the deal. Rates are inversely proportional to sale price: smaller deals carry higher percentages, larger deals carry lower ones. The math behind this is simple. A broker performing the work to sell a $500,000 business does roughly the same amount of work as a broker selling a $5 million business. The gross dollar commission on the larger deal is already higher at a lower percentage, so the rate steps down.
Sale Price | Typical Commission | Minimum Fee | Market Tier |
Under $1M | 8% to 12% (10% standard) | $10K to $25K | Main Street |
$1M to $5M | 6% to 10% or Double Lehman | $10K to $25K | Upper Main / Lower Mid |
$5M to $10M | 4% to 8% | $35K to $50K | Lower Middle Market |
$10M to $50M | 1% to 5% (blended) | $50K to $250K | Middle Market |
$50M+ | 1% to 4% (negotiated) | $250K+ | Upper Middle Market |
I want to emphasize the minimum fee column. If your business sells for $150,000 and the broker has a $15,000 minimum, that is effectively a 10% commission. But if your business sells for $80,000, that same minimum means you are paying nearly 19%. Minimum fees exist because the work involved in selling a small business is not proportionally less than selling a larger one. That is a reality of broker economics, and it is worth understanding before you sign. We cover this and related cost considerations in our guide to choosing a business broker.
The Double Lehman Formula Explained
The Double Lehman (also called the Modern Lehman) is the most common tiered commission structure for businesses selling in the $1 million to $5 million range. It was developed because the original Lehman formula from 1960 produced fees that were too low for modern deal work. The Double Lehman doubles each tier from the original scale.
Here is the structure:
10% on the first $1 million of the sale price
8% on the second $1 million (from $1M to $2M)
6% on the third $1 million (from $2M to $3M)
4% on the fourth $1 million (from $3M to $4M)
2% on every dollar above $4 million
A worked example makes this concrete. If your business sells for $3 million under the Double Lehman, the commission is: $100,000 (10% of the first million) plus $80,000 (8% of the second million) plus $60,000 (6% of the third million). Total: $240,000, which is a blended rate of 8%. For a $5 million sale, the total is $300,000, a blended rate of 6%.
The Double Lehman is one of the most misunderstood aspects of broker pricing. Sellers hear "10% commission" and assume that means 10% of the entire sale price, even on a $4 million deal. It does not. The tiered structure brings the effective rate down as the deal size goes up. Understanding this is part of understanding how much your business could sell for and what you will actually net at closing.
What Is the Lehman Formula in Business Sales?
The Lehman formula is a tiered, sliding-scale commission structure originally created by Lehman Brothers in 1960 for M&A advisory work. The original scale was 5-4-3-2-1: 5% on the first million, stepping down to 1% above $4 million. Because inflation made those rates too low, the industry developed the Double Lehman (10-8-6-4-2), which is the version most business brokers use today for deals in the $1M to $5M range.
Who Pays the Business Broker Commission?
The seller pays. In nearly every business sale transaction in the United States, the full commission comes out of the seller's proceeds at closing. This is confirmed across virtually every industry source and is the standard arrangement at every deal size.
The commission is calculated against the total transaction value, which includes cash, securities, and other consideration paid at closing. Where it gets complicated is deferred consideration: earnouts, promissory notes, and holdbacks. Some brokers calculate their commission on the full committed deal value, including the maximum potential earnout and full promissory note amount. Others agree to collect only on cash received at closing, with additional commission payable as deferred payments come in.
This is a critical detail to nail down before you sign. If your deal includes a $200,000 earnout tied to performance targets the buyer may never hit, you do not want to pay a commission on money you may never receive. Ask the question directly: is the commission based on cash at closing or on the maximum deal value? It is one of the key questions to ask any broker before signing.
If the deal falls through before closing, no success fee is owed. That is the fundamental structure of success-fee economics: the broker's payday is entirely contingent on a closed transaction. This is also why only 20% to 30% of businesses listed for sale actually sell, according to Morgan and Westfield and other industry estimates. Brokers absorb that risk every time they take a listing.
What the Broker's Commission Actually Covers
The commission is not just for finding a buyer. It covers the full scope of work from engagement to closing. Here is what is typically included:
Valuation. The broker prepares a broker's opinion of value based on your financials, industry benchmarks, and comparable transactions. This is not a certified appraisal (which is a separate service), but it is the market-derived estimate that sets your asking price.
Marketing materials. The broker creates the Confidential Information Memorandum (CIM), the detailed document that presents your business to qualified buyers. A strong CIM covers financials, operations, market position, growth opportunities, and deal terms.
Listing and buyer outreach. Beyond posting on platforms like BizBuySell, a good broker taps proprietary buyer databases, runs direct outreach to strategic buyers, contacts private equity firms with relevant criteria, and works industry contacts to generate qualified interest.
Buyer screening. The broker filters inquiries to eliminate browsers, verifies financial capacity (proof of funds, SBA pre-qualification), and presents only credible buyers to you. This protects your time and your confidentiality.
Negotiation management. The broker handles the back-and-forth on price, terms, earnouts, transition periods, and working capital adjustments. They serve as a buffer during what can be an emotionally charged process.
Due diligence and closing coordination. The broker organizes the data room, coordinates with your accountant and attorney, fields buyer questions, resolves deal obstacles, and keeps all parties moving toward closing.
Confidentiality protection. Throughout the process, the broker ensures identifying details are only shared with NDA-signed, qualified buyers, protecting you from employee anxiety, customer flight, and competitor awareness.
What is typically not included: legal fees ($3,000 to $10,000+), accounting fees, certified valuations, and specialty marketing like international buyer outreach. These are separate costs. Our documents needed to sell a business guide covers the full set of paperwork and professional services involved.
Upfront Retainers: When They Make Sense and When They Do Not
For Main Street businesses under $1 million, most brokers do not charge an upfront retainer. The commission is the whole fee, and it is paid only at closing. That is the standard, and it is the arrangement most small business sellers should expect.
For lower middle-market deals ($1M to $5M), retainers become more common. They typically range from $5,000 to $25,000 and are meant to cover the upfront cost of valuation, CIM preparation, and initial marketing. For deals above $5M handled by M&A advisory firms, retainers are nearly universal, running from $15,000 to $50,000 or more.
The critical question: does the retainer credit against the success fee at closing, or is it an additional charge on top? Some brokers treat the retainer as a deposit that reduces the final commission. Others keep it as a separate fee. This is one of the most important contract terms to clarify before signing, because on a $2 million deal with a $180,000 commission, a $15,000 retainer that does not credit against the success fee adds nearly 8% to your total brokerage cost.
Should I Be Worried About Upfront Fees?
Not automatically. Small retainers ($1,000 to $2,500) for valuation and marketing setup are common and can be reasonable. Large upfront retainers for Main Street deals, however, should raise questions. A broker who demands $10,000 up front on a $500,000 listing is shifting risk from themselves to you. At the lower middle-market level, retainers that credit against the success fee are the industry norm and generally acceptable. We walk through fee structure evaluation as part of our seller advising process.
Tail Clauses: The Contract Term Most Sellers Overlook
A tail clause (also called a broker protection clause) gives the broker the right to collect their commission if the business sells after the listing agreement expires, as long as the buyer was introduced by the broker during the listing period. Typical tail durations in business brokerage run 6 to 24 months, with 12 months being the most common.
The purpose is straightforward: a broker introduces a buyer in month 11 of a 12-month listing, the listing expires, and the seller closes with that buyer in month 14. Without a tail clause, the broker just did 11 months of work for free. So the tail is reasonable in principle.
Where it gets problematic is when the tail clause covers any buyer, not just buyers the broker introduced. Some exclusive listing agreements include language that entitles the broker to a commission on any sale during the tail period, regardless of how the buyer found the business. That means if you relist with a new broker after the old agreement expires and a new buyer comes through the new broker, you could owe commissions to both brokers. It has happened. It is not common, but it is devastating when it does.
Before signing any listing agreement, negotiate these specific tail protections: limit the tail to 12 months or less; ensure it applies only to buyers the broker actually introduced and documented; require the broker to deliver a written list of introduced buyers when the agreement expires; and exclude any buyers you were already in discussions with before the engagement.
Are Business Broker Commissions Negotiable?
Yes. There is no regulatory standard, no fixed pricing schedule, and no industry-imposed minimum rate. Every broker sets their own rates, and sellers can negotiate.
That said, negotiating a broker's commission is a balancing act. Your leverage increases with deal size, the quality of your financials, and the number of competing broker proposals you collect. Business Brokers Guide reports that sellers have reduced rates by 1 to 3 percentage points when they have strong leverage and concrete competing quotes from other brokers.
Here is my honest take on this. Cutting a broker's fee from 10% to 7% to save $30,000 on a $1 million deal might feel smart, but if it reduces the broker's motivation or the quality of marketing your business receives, you could easily lose more on the sale price than you saved on the fee. A broker earning a full commission has every incentive to fight for every dollar of value. A broker who took the listing at a discount because they needed the work may not. I would rather pay full rate to someone who is going to run a competitive process and push buyers to their highest offer. That is what we do at East Coast Advisory Team, and it is how we think about the economics of every deal.
What Factors Give Sellers More Negotiating Power on Fees?
Four factors increase your leverage: a larger sale price (the absolute dollar commission is higher even at a lower rate), clean and well-documented financials (brokers prefer easier-to-sell businesses), multiple competing broker proposals (gather at least three), and strong market conditions where buyer demand is high and brokers are competing for listings. If your business has all four, you are in a strong position to negotiate terms.
The Bottom Line on Business Broker Fees
Broker fees are the cost of professional representation in the most significant financial transaction most business owners will ever go through. The fee structure is not complicated once you understand it: a percentage of the sale price, scaled to deal size, paid by the seller at closing. What matters more than the rate itself is what you are getting for it. A good broker earns their commission by running a process that produces qualified buyers, competitive offers, and a successful close. A bad broker earns their commission by getting you to sign a contract. Know the difference before you sign. Learn how to evaluate the full selling process so you know what to expect.

Frequently Asked Questions
How much does a business broker charge to sell a business?
For small businesses valued under $1 million, most brokers charge 8% to 12% of the final sale price, with 10% being the industry standard. For businesses valued between $1 million and $5 million, the Double Lehman formula (10-8-6-4-2 by million-dollar tier) produces blended rates of 6% to 9%. For deals above $5 million, rates typically drop to 4% to 8%, and for transactions above $25 million, success fees run 1% to 4%.
Does the buyer or the seller pay the business broker?
The seller pays the entire commission in nearly all business sale transactions. The fee is deducted from the sale proceeds at closing. If a buyer has their own broker or advisor, the buyer typically pays that advisor separately, or the two brokerages split the commission in a co-brokerage arrangement.
What is the Double Lehman formula?
The Double Lehman is a tiered commission structure that charges 10% on the first $1 million of the sale price, 8% on the second million, 6% on the third, 4% on the fourth, and 2% on every dollar above $4 million. It is the most common fee structure for business sales in the $1 million to $5 million range and produces blended rates of 6% to 9% depending on total sale price.
What is a tail clause in a business broker contract?
A tail clause extends the broker's right to collect a commission for a set period (typically 6 to 24 months) after the listing agreement expires, if the buyer was introduced during the listing term. To protect yourself, ensure the tail applies only to broker-introduced buyers, request a written list of those buyers at expiration, and try to limit the duration to 12 months or less.
Can you negotiate a business broker's commission?
Yes. Business broker commissions are negotiable. Your leverage increases with deal size, financial documentation quality, and competing broker proposals. Sellers have reduced rates by 1 to 3 percentage points with strong leverage. However, cutting too aggressively can reduce broker motivation and the quality of marketing your business receives.
