Business Broker Fees: How Much Do Business Brokers Charge to Sell a Business?

Most US business brokers charge a success fee of 8% to 12% of the sale price on Main Street deals under $1 million, with 10% the single most common rate. Fees fall as deal size rises: roughly 6% to 10% between $1M and $5M, and a blended 3% to 8% above $5M, usually structured as a Double Lehman formula. Nearly every broker also sets a minimum fee, commonly $15,000 to $50,000, and many now charge a retainer or monthly engagement fee that is credited against the success fee at closing.

Broker commission is the largest single cost of selling a business, and it is almost always negotiated rather than posted. There is no regulated rate. What follows is what the market actually charges in 2026, how the formulas work, and the clauses in the listing agreement that cost sellers real money after the fact.

How much do business brokers charge?

The rate depends almost entirely on deal size, because the work of selling a $400,000 business is not much smaller than the work of selling a $4,000,000 one. Smaller deals carry higher percentages to make the engagement viable.

To put that in context, the median US small business sale price in recent BizBuySell Insight Report data has run around $349,000. At the standard 10%, that is roughly $35,000 in commission on a typical Main Street transaction. On a $500,000 sale you should expect $40,000 to $60,000 depending on the rate and whether a minimum applies.

These bands come from broker fee disclosures, the IBBA and M&A Source Market Pulse survey, and the Pepperdine Private Capital Markets Report, all of which track what advisors actually charge rather than what they advertise. Individual firms vary, and a broker in a hot metro with a strong track record will hold their rate more firmly than one who needs the listing.

Who pays the business broker, the buyer or the seller?

The seller pays the business broker in the overwhelming majority of transactions. The commission comes out of the sale proceeds at closing, so the seller never writes a separate check. Buyer-paid fees exist but are unusual, and mostly appear in larger transactions where a buy-side advisor is engaged separately by the acquirer.

When both sides have their own representation, the two brokers typically split a co-brokerage fee out of the seller-paid commission rather than charging twice. What you should never assume is that a broker who introduced themselves as helpful is working for you. In most listings the broker has a contract with the seller and a duty to the seller. A buyer relying on the listing broker for advice is relying on the other side of the table.

How the Lehman formula and the Double Lehman formula work

Once deals pass roughly $1M, a flat percentage starts to overcharge, so advisors use a sliding scale. The original Lehman formula, developed for investment banking, steps the rate down by each million of transaction value. Because small business deal sizes are far below what that scale was designed for, the Double Lehman has become the working standard in the lower middle market.

Work an example. On a $3,000,000 sale under Double Lehman: 10% of the first million is $100,000, 8% of the second is $80,000, and 6% of the third is $60,000. Total commission $240,000, a blended rate of 8%. Under Standard Lehman the same deal costs $120,000, or 4% blended. The difference between the two formulas on a single mid-size transaction is $120,000, which is why you should confirm in writing which one your agreement uses.

Watch for the Modified Lehman too, which changes the step size (for example 10% on the first $2M, then 6%, then 4%) and can look cheaper on the headline rate while costing more on your specific deal size. Always ask the broker to compute the fee on your actual expected sale price rather than comparing percentages in the abstract.

What is a business broker minimum fee?

A minimum fee is the floor the broker collects regardless of sale price, commonly $15,000 to $50,000 in 2026. It exists because the fixed work of a sale (packaging financials, marketing, screening buyers, managing diligence to closing) does not shrink proportionally with price.

The minimum only bites on small transactions, and there it bites hard. A $120,000 business sold under a 10% commission with a $25,000 minimum is paying an effective rate of nearly 21%. If your business is likely to sell in the low six figures, the minimum fee is the most important number in the agreement, not the percentage. Ask for it explicitly. It is often buried in a schedule rather than stated in the fee paragraph.

Do business brokers charge a retainer?

Increasingly, yes. Traditional Main Street brokers often worked on pure success fees, but the market has shifted. Upfront retainers commonly run $5,000 to $25,000, with established firms at the higher end. In the lower middle market, advisors have moved toward monthly engagement fees of roughly $2,500 to $10,000, and recent IBBA and M&A Source Market Pulse data shows that shift away from one-time retainers toward monthly or milestone-based billing.

A retainer is not automatically a bad sign. It filters out sellers who are not serious, and it funds real work such as recasting financials and building the confidential information memorandum. Two questions decide whether it is fair:

• Is it credited against the success fee at closing? A credited retainer costs you nothing if the deal closes. A non-credited one is pure additional cost.
• What specific deliverables does it buy? A retainer that produces a valuation, a recast profit and loss, and a marketing package you own is defensible. One that buys a listing on a website is not.

What does the broker commission actually pay for?

The commission is not a finder fee. On a well-run engagement it covers valuation and pricing, recasting your financials into the normalized earnings a buyer underwrites, writing the confidential memorandum, confidential marketing to a buyer list, screening and qualifying inquiries, managing the offer process, and shepherding the deal through diligence and financing to a close.

That last part is where brokers earn their keep and where inexperienced sellers underestimate the work. A large share of signed letters of intent never close. Buyers walk during diligence, lenders reprice, and a quality of earnings review knocks holes in the add-backs. Someone has to hold that process together for three to nine months.

What is a tail provision in a broker agreement?

A tail provision keeps the broker entitled to their fee for a set period after the listing agreement ends, typically 12 to 24 months, if you sell to a buyer the broker introduced during the engagement. It is standard and reasonable in principle. It stops a seller from firing the broker and closing quietly with a buyer the broker sourced.

It becomes a problem when it is drafted broadly. Two things to negotiate before signing: insist that the tail applies only to a written list of named buyers the broker actually contacted, delivered to you when the agreement terminates, and cap the tail period at 12 months. An open-ended tail that covers "any buyer" can leave you owing a commission on a sale the broker had nothing to do with two years later.

While you are reading the agreement, check the exclusivity period as well. Six to twelve months is normal. Anything longer locks you to a broker whose performance you cannot yet judge. Brokers routinely send these agreements as PDFs and it is perfectly fine to sign the listing agreement electronically, but read the tail, the exclusivity term, and the minimum fee before you do, because all three are far easier to change before signature than after.

Are business broker fees negotiable?

Yes. Commission is not set by law or by any board. It is a private contract, and the rate reflects how much the broker wants your listing. Your leverage rises with clean books, an attractive industry, a realistic asking price, and a business that is not dependent on you personally.

What tends to work in practice is negotiating structure rather than the headline rate. Brokers resist cutting 10% to 8% because it signals their fee is soft. They are far more willing to lower the minimum fee, credit the retainer fully, shorten the tail, add a success bonus above a target price, or agree a reduced rate on the portion of the price above a threshold. A sliding scale that pays them more for exceeding your number aligns both sides better than a flat discount does.

The strongest negotiating position is knowing what the business is worth before you walk in. A broker opinion of value is free and is also a sales document, and our comparison of a broker valuation against an independent appraisal explains where the two diverge. Running your own numbers first means you can tell the difference between a realistic price and a listing price designed to win your signature.

How broker fees compare to the alternatives

A broker is one of three routes to a sale, and the cost structures are genuinely different.

For an online business, an open marketplace is often the direct substitute for a broker, and the fee math is similar once you include listing packages. Our breakdown of Flippa fees and how its valuation tool works walks through what that route costs end to end. For an offline business where you already have a buyer, going direct is realistic, and the guide to selling a business without a broker covers what you take on when you do.

Is a business broker worth 10%?

It depends on one thing: whether the broker produces a better outcome than you would alone, by more than the fee. That is a real question, not a rhetorical one.

A broker is usually worth it when you have no buyer, you need the sale kept confidential from staff and customers, your financials need recasting before a lender will look at them, or you cannot afford the months of attention the process demands while still running the business. Competitive tension between multiple qualified buyers routinely moves the price more than 10%, and that tension is exactly what a broker is selling.

A broker is usually not worth it when a buyer has already approached you, when the business is small enough that the minimum fee swallows a fifth of the proceeds, or when you are selling to a family member, a partner, or an employee. In those cases you are paying a marketing fee for marketing you do not need, and the money is better spent on a transaction attorney and a clean set of books.

Whichever route you choose, decide on price before you decide on representation. Knowing your likely range tells you what 10% actually costs you in dollars and whether the broker asking price is defensible. You can run your revenue and earnings through our business valuation calculator to get a three-method estimate benchmarked against comparable sales, then use our guide to what multiple businesses sell for to sanity-check the number a broker quotes you. It is an educational estimate rather than a certified appraisal, which is exactly what you need at the stage where you are still choosing how to sell.
