How Do Business Brokers Make Money? Commissions Explained
Nearly every business broker is paid the same way: a success fee, charged as a percentage of the sale price, collected only when your business actually sells. The percentage, the scale it slides on, and whether anything is charged upfront vary widely. Here is exactly how the money works, with real numbers.

The Five Ways Brokers Get Paid
Success fees (commissions): a percentage of the final sale price, paid out of closing proceeds. This is the core of nearly every broker's income and the model this guide focuses on.
Retainers and engagement fees: upfront or monthly payments some firms charge before the business sells. Common at mid-market M&A firms, less common on main street.
Minimum fees: a floor on the commission, typically $10,000 to $25,000, so very small deals still cover the months of work a sale requires.
Co-brokerage splits: when two brokerages cooperate on a deal (one represents the seller, one brings the buyer), they split a single commission rather than charging twice.
Ancillary fees: a minority of firms charge separately for valuations, marketing packages, or the confidential information memorandum. Always ask what is included in the success fee and what is billed separately.

The Success-Fee Model: Why Brokers Only Get Paid When You Do
A success fee in a business sale works like this: you sign a listing agreement that sets a commission percentage. The broker then spends months valuing, packaging, marketing, and negotiating. If and only if the business closes, the fee is deducted from the sale proceeds at the closing table. No closing, no fee.
Why the Model Aligns Incentives
- The broker is paid from the same event you are. Both of you collect at closing, from the same wire. A broker on a pure success fee has one path to revenue: getting your deal done at a price a real buyer will actually pay.
- Higher price means higher fee. Because the fee is a percentage, every additional dollar of sale price puts more money in the broker's pocket too. The broker has a direct financial reason to negotiate hard on your behalf.
- The broker carries the risk of a failed process. Preparing and marketing a business takes hundreds of hours. On a success-fee-only engagement, that time is the broker's investment, not your bill.
- It forces honest intake conversations. A broker paid only at closing has little reason to take on a listing priced above what the market will pay, because an unsellable listing earns nothing. That reality check at the first meeting protects you from a year on the market with no offers.
The Model's Honest Trade-Offs
- Brokers must be selective. Because they eat the cost of failed processes, success-fee brokers turn down businesses they do not believe will sell. If several brokers decline your listing, treat it as market feedback worth hearing.
- Commission percentages look large as a single number. A $120,000 fee on a $1,000,000 sale is real money. The right way to evaluate it is against the outcome: the net proceeds you keep, the confidentiality preserved, and the months of full-time work you did not do yourself.
- A percentage fee rewards closing, and most agreements also define the fee off total deal value including seller notes and earnouts. Read the definition of "transaction value" in any agreement before signing.
Typical Commission Structures, With Real Numbers
Business broker commission structures fall into three families. Which one you see depends mostly on the size of your business.
1. Flat Percentage: The Main Street Standard
For businesses selling under roughly $2,000,000, most brokers quote a flat 10% to 12% of the sale price. Some markets and franchised brokerage networks run closer to 8%, others to 12%, but 10% is the number you will hear most often in the United States.
Worked example: $800,000 sale at 10%
Sale price $800,000, commission 10%, broker fee $80,000, paid from proceeds at closing. You never write a check: the closing attorney or escrow agent disburses the fee from the buyer's funds, and you receive the balance.
On very small deals the flat percentage collides with the minimum fee. If a broker's minimum is $15,000 and your business sells for $90,000, the fee is $15,000 (about 17%), not $9,000. The work to sell a $90,000 business is not much less than the work to sell a $900,000 one, which is why minimums exist and why some brokers simply decline listings below a size threshold.
2. The Lehman Scale: Where Sliding Fees Began
The Lehman formula dates to investment banking in the 1960s. It slides the percentage down as the price goes up: 5% of the first $1,000,000, 4% of the second $1,000,000, 3% of the third, 2% of the fourth, and 1% of everything above $4,000,000.
Worked example: $5,000,000 sale on the original Lehman scale
- 5% of the first $1,000,000 = $50,000
- 4% of the second $1,000,000 = $40,000
- 3% of the third $1,000,000 = $30,000
- 2% of the fourth $1,000,000 = $20,000
- 1% of the final $1,000,000 = $10,000
- Total fee: $150,000, an effective rate of 3%
The original Lehman percentages were set when $1,000,000 was a very large transaction. They were never adjusted for sixty years of inflation, so almost no firm still quotes them straight. Instead, the structure survived and the numbers doubled.
3. Double Lehman: The Modern Mid-Market Default
Double Lehman (sometimes called Modern Lehman) simply doubles each tier: 10% of the first $1,000,000, 8% of the second, 6% of the third, 4% of the fourth, and 2% above $4,000,000. It is the most common quoted scale for lower mid-market deals between roughly $2,000,000 and $25,000,000.
Worked example: $5,000,000 sale on Double Lehman
- 10% of the first $1,000,000 = $100,000
- 8% of the second $1,000,000 = $80,000
- 6% of the third $1,000,000 = $60,000
- 4% of the fourth $1,000,000 = $40,000
- 2% of the final $1,000,000 = $20,000
- Total fee: $300,000, an effective rate of 6%
Notice what the sliding scale accomplishes: the marginal rate on the last dollar is low, but the early tiers keep the fee meaningful on smaller deals. A $2,000,000 sale on Double Lehman costs $180,000 (9% effective), while a $10,000,000 sale costs $400,000 (4% effective). The bigger the deal, the lower the blended percentage, which mirrors the economics: the work does not scale linearly with price.

Broker Retainers and Upfront Fees: Why Some Firms Charge Them
A broker retainer is money paid before the business sells. It shows up in three forms, and each has a legitimate rationale you should understand even if you ultimately choose a firm that does not charge one.
Engagement Fees
A single upfront payment, often $2,500 to $25,000 depending on deal size, charged when you sign the listing agreement. Firms position it as covering valuation work and preparation of the marketing package.
Monthly Retainers
Common at mid-market M&A firms: $5,000 to $15,000 per month for the life of the engagement. Over a 9-month process that is $45,000 to $135,000 before any success fee.
Marketing and Valuation Fees
Separate charges for the formal valuation report, the confidential information memorandum, or listing-site placement. More common among franchised main street brokerages.
The Case Firms Make for Retainers
Firms that charge retainers argue they filter for committed sellers, fund genuinely expensive preparation work, and let the firm run fewer engagements with more attention on each. Those are real considerations, especially at the larger end of the market where a single process can consume a senior banker for a year. The retainer question is less about right and wrong and more about who carries the risk of a deal that never closes: with a retainer you share that risk, and on a pure success fee the broker carries it alone.
What to Verify Before Paying Anything Upfront
- Is the retainer credited against the success fee at closing? A credited retainer is a deposit; an uncredited one is an added cost.
- What specific deliverables does the upfront payment buy, and by what date?
- What happens to money already paid if you cancel the engagement, or the firm does?
- What percentage of the firm's listings from the past two years actually closed? An upfront-fee model can survive on signings alone; a success-fee model cannot.
One Modern Example: How BridgeBook Prices
To make this concrete, here is how BridgeBook, the founder-led brokerage behind this guide, structures its own fees. We publish them because fee opacity is the single biggest complaint sellers raise about this industry.
No Retainer, Ever
BridgeBook charges nothing upfront: no engagement fee, no monthly retainer, no separate valuation or marketing bill. The fee is earned at closing or not at all.
10% Sliding to 3%
The success fee is 10% on the first $1,000,000 of the sale price and slides down by tier to 3% on value above $7,000,000, so the blended rate falls as your deal gets larger.
Up to $3,500 Off the Fee
Booking and attending a free 45-minute exit consultation locks in a $2,500 credit toward the success fee, and requesting the free valuation report adds another $1,000. The $3,500 total is applied only when BridgeBook sells your business.
One Person Owns Your Deal
BridgeBook is founder-led by Legend Atty. The person who values your business and quotes the fee is the person accountable for closing the deal, not a franchise office three layers away.

What a Broker Actually Does to Earn the Fee
A commission only feels expensive until you itemize the work behind it. A competently run sale process typically takes 6 to 9 months and hundreds of hours. Here is where those hours go:
1. Valuation and Financial Recasting
The broker rebuilds your financials the way a buyer will read them: normalizing owner compensation, adding back personal expenses, and calculating Seller's Discretionary Earnings or adjusted EBITDA. Getting this right sets the price, and getting it wrong sinks deals months later in due diligence.
2. The Confidential Information Memorandum
A professional CIM is a 20-to-50-page document covering operations, financial history, customers, staff, and growth levers. It is the difference between a buyer making a serious offer and a buyer asking you 400 questions one email at a time.
3. Confidential Marketing and Buyer Screening
The broker markets the business blind (no name, no exact location), fields inquiries, requires signed NDAs, and verifies proof of funds before anyone learns whose business is for sale. Screening is most of the volume: for every serious buyer there are typically dozens of tire-kickers, and the broker absorbs all of them so your employees, customers, and competitors never learn you are selling.
4. Negotiation and Deal Structuring
Multiple interested buyers create competitive tension only if someone orchestrates it. The broker runs the offer process, pushes back on low bids, and negotiates structure: price, seller financing, earnouts, working capital, and transition terms. This stage is where a good broker most directly pays for the fee.
5. Due Diligence Quarterbacking
Between the letter of intent and closing, the buyer verifies everything. The broker manages the document flow, keeps the buyer's lender and attorneys on schedule, and solves the weekly problems that would otherwise kill momentum. Most collapsed deals die here, from drift rather than discovery.
6. Closing Coordination
Purchase agreement review alongside your attorney, lease assignments, license transfers, escrow, and funds disbursement. Only when the wire lands does the broker's fee exist.
For Aspiring Brokers: How the Money Flows Inside a Firm
If you are reading this because you want to become a broker rather than hire one, the commission math above is your revenue model. Here is how it typically divides once a deal closes:
Most brokers are 1099 independent contractors on commission splits, not salaried employees. No closings means no income.
A new broker at an established firm typically keeps 50% to 60% of the commissions they generate. The house share pays for the brand, leads, listing platforms, and back office.
Experienced producers negotiate 70% to 90% splits, and top performers often go independent and keep everything while covering their own costs.
Income is lumpy by design. Deals take 6 to 12 months from engagement to closing, so a first-year broker can work hard for nine months before the first commission check arrives. Plan for 12 months of living expenses before you start.
One example of the math: a broker on a 50% split who closes three main street deals in a year at an average $600,000 sale price and 10% commission generates $180,000 in gross fees and keeps $90,000.

Questions to Ask Any Broker About Fees
Ask these before signing a listing agreement. A good broker will answer every one without flinching:
- What is your exact commission structure, in writing, including how it is calculated on seller notes, earnouts, and assumed debt?
- Do you charge any retainer, engagement fee, or marketing fee? If so, is it credited against the success fee at closing?
- Is there a minimum fee, and what is it?
- How long is the exclusivity period in your listing agreement, and what does it take to exit early?
- Is there a tail period after the agreement ends where you still earn the fee if a buyer you introduced closes? How long?
- Do you co-broker with buyer-side brokers, and does that change my total fee?
- Of the businesses you listed in the past 24 months, how many closed?
- Who personally works my deal from valuation through closing?
- How did you arrive at your recommended asking price, and can you show me the comparable data behind it?
One caution on the last question: the highest opinion of value is not the best broker. Some firms quote optimistic prices to win the listing, then walk the price down after months on the market. A broker who shows you comparable sales and quotes a defensible number, even a lower one, is telling you the truth about what will close.
Frequently Asked Questions
How much commission does a business broker charge?
Most business brokers charge a success fee of 10% to 12% of the final sale price on main street deals (businesses selling for under roughly $2,000,000). Larger deals typically use a sliding scale like the Lehman or Double Lehman formula, where the percentage drops as the price rises. Many brokers also set a minimum fee, commonly $10,000 to $25,000, so very small deals still cover the work involved.
What is a success fee in a business sale?
A success fee is a commission paid only when the business actually sells, calculated as a percentage of the final sale price and paid out of closing proceeds. If the deal never closes, the broker earns nothing. This is the dominant compensation model in business brokerage because it puts the broker and the seller on the same side: both get paid at the same moment, from the same event.
Do business brokers charge upfront fees or retainers?
Some do. Retainers typically range from a few thousand dollars for a main street engagement to $5,000 to $15,000 per month at mid-market M&A firms. Firms that charge them usually point to real upfront costs: valuation work, preparing the confidential information memorandum, and marketing. Other firms, including BridgeBook, work on a success-fee-only basis with no retainer. If a broker charges a retainer, always ask whether it is credited against the success fee at closing.
What is the Double Lehman formula?
Double Lehman is a sliding commission scale: 10% of the first $1,000,000 of the sale price, 8% of the second, 6% of the third, 4% of the fourth, and 2% of everything above $4,000,000. On a $5,000,000 sale that works out to $300,000, an effective rate of 6%. It is double the original Lehman formula (5-4-3-2-1), which dates to the 1960s and was never adjusted for inflation, which is why most modern firms quote Double Lehman or their own tiered scale instead.
How do new business brokers get paid?
Most business brokers are independent contractors paid on commission splits, not salary. A new broker at an established firm typically keeps 50% to 60% of the commissions they generate, with the house taking the rest for brand, leads, and infrastructure. Experienced brokers negotiate 70% to 90% splits or go independent. Because deals take 6 to 12 months to close, first-year income is lumpy: many new brokers earn little for months, then receive large commission checks when deals close.
