Business Broker Fees: What Brokers Charge and What You Get

Business broker fees on a typical Main Street sale run 8% to 12% of the final sale price, paid as a success fee only when the deal actually closes. On a $349,250 median-priced small business - the current figure from BizBuySell's Q2 2026 Insight Report - that commission works out to roughly $28,000 to $42,000. The International Business Brokers Association (IBBA) puts the full Main Street range at 8% to 15%, with the highest end reserved for the smallest, most labor-intensive listings. Above about $1 million in deal value, most brokers and M&A advisors switch to a tiered scale, commonly a version of the Lehman formula, so the percentage shrinks as the price climbs. In exchange, a broker prices the business, markets it confidentially, screens and negotiates with buyers, and manages the deal through closing.

What business broker fees actually cover

A broker's commission is not a fee for putting a listing online. It's payment for a bundle of work that, done badly, is exactly what sinks a sale. That work breaks down into five pieces:

• Valuation and pricing. Setting a number grounded in comparable sales and real cash flow, not what the owner feels the business should be worth.
• Confidential marketing. Running a blind listing, screening inquiries, and keeping the sale quiet from employees, customers and competitors until the seller is ready to disclose.
• Buyer qualification. Filtering out tire-kickers and confirming a buyer actually has the cash or financing to close before burning the seller's time on them.
• Negotiation. Acting as a buffer between seller and buyer so hard conversations about price and terms don't damage the relationship needed to get to closing.
• Deal management through closing. Coordinating the buyer's lender, attorneys and accountants, and keeping the transaction on schedule when any one of those parties stalls.

Skipping a broker to keep the commission means taking all five jobs on yourself - see our guide on how to sell a business without a broker for the honest trade-offs of going it alone.

How business broker commissions are structured

Most Main Street brokers work on a straight percentage of the total sale price, charged only on success - if the business doesn't sell, the seller typically owes nothing beyond any retainer already paid. For businesses valued under roughly $1 million, that percentage commonly lands at 8% to 12%, occasionally reaching into the low teens on the smallest, hardest-to-sell listings where the broker's time investment barely changes with deal size. A $400,000 deal and a $150,000 deal both require the same core steps - valuation, marketing, buyer screening, closing paperwork - so brokers price smaller listings at the top of the range to make the engagement worthwhile.

As deal value climbs past $1 million, flat percentages stop making sense for either side: a flat 10% fee on a $5 million sale would be $500,000, disproportionate to the incremental work involved. That's where tiered formulas take over.

The Lehman formula: how fees scale on bigger deals

The Lehman formula is the industry's standard shorthand for a declining, tiered commission on larger transactions. The classic version charges:

• 10% on the first $1 million of the sale price
• 8% on the second $1 million
• 6% on the third $1 million
• 4% on the fourth $1 million
• 2% on everything above $4 million

On a $3 million sale, that math works out to $100,000 on the first million, $80,000 on the second, and $60,000 on the third - a total of $240,000, or 8% blended across the whole deal. Many firms now run a "modified Lehman" with slightly higher tiers to reflect rising deal complexity, so it's worth asking any broker for their exact scale in writing before signing an engagement letter rather than assuming the textbook version applies.

Minimum fees on small listings

Below a certain deal size, percentage-based pricing breaks down entirely - 10% of a $150,000 business is only $15,000, which rarely covers a broker's time across months of marketing and negotiation. To cover that gap, most Main Street brokers set a minimum fee, commonly in the $15,000 to $25,000 range, that applies regardless of how the percentage math works out. A seller with a small business should ask upfront whether a minimum applies and at what sale price it would kick in, since it changes the effective commission rate on the lower end of a deal.

Retainer and upfront fees

Most reputable Main Street brokers work entirely on commission, with nothing due until closing. Some, particularly on larger or more complex deals, charge a modest upfront retainer or engagement fee, sometimes structured as monthly payments during the marketing period rather than a single lump sum, which is then credited against the final commission at closing. A retainer is a legitimate way for a broker to cover the real cost of preparing marketing materials and running a valuation before there's any guarantee of a sale - but a large upfront fee with a vague success component is a red flag worth walking away from. Separately, expect to pay your own transaction attorney and accountant regardless of whether a broker is involved; those are not broker fees, but they are real costs of closing any sale correctly.

Flat-fee and hourly brokers: the exceptions worth knowing

A smaller share of the market works outside the straight-commission model. Flat-fee listing services will put a business in front of buyers for a fixed price, sometimes a few thousand dollars, but they typically stop there - no valuation work, no buyer screening, no negotiation support, and no help getting to closing. Some advisors on larger or more complex transactions bill hourly or charge a fixed advisory fee instead of a percentage, which can make sense on a deal where the work is unusually heavy relative to the sale price, such as one requiring extensive licensing transfers or a messy ownership structure. For a typical trades business sale, though, a success-based commission remains the norm because it aligns the broker's incentive with the seller's: the broker only gets paid if the deal actually closes, and closes at a real price.

Worked example: what a broker costs on a real deal

Take BizBuySell's Q2 2026 median: a $349,250 sale price with a 2.7x average SDE multiple. At a 10% commission, the broker's fee is $34,925. At 8%, it's $27,940; at 12%, $41,910. Now scale up to a $2.5 million trades business sold under a standard Lehman formula: $100,000 on the first million, $80,000 on the second, plus $90,000 (6% of the remaining $1.5 million calculated on the third-tier rate for that portion) - landing the total commission somewhere around $270,000, an effective blended rate under 11%. The blended rate keeps falling as deal size grows, which is exactly the point of a tiered structure: it prices the broker's marginal work accurately instead of charging a flat percentage that would be excessive on a large deal or unprofitable on a small one.

Run the same math on a $700,000 deal - solidly inside Main Street territory - at a flat 10% and the fee is $70,000. If a minimum-fee clause of $25,000 applies instead of the percentage, that only matters below roughly a $250,000 sale price; above that, the percentage math wins out and the minimum never comes into play. Knowing which side of that line a business sits on before signing an engagement letter avoids a surprise on the closing statement.

What you get for the fee - and what you don't

The clearest way to judge whether a commission is worth paying is to compare it against the alternative, not against zero. A broker's fee typically buys:

• Access to a buyer network the broker has built over years, not a single classified listing.
• A negotiation buffer that keeps price disagreements from becoming personal between seller and buyer.
• Confidentiality management - NDAs before financials go out, and a blind listing that doesn't tip off employees or competitors.
• Deal triage - the experience to spot when a buyer's financing is shaky or an offer is going nowhere, before it eats a month of the seller's time.

What it doesn't buy is a guaranteed sale, a guaranteed price, or immunity from a deal falling apart in diligence. Deals still stall or die over unrealistic pricing expectations, financing that falls through, or a buyer who loses confidence once they're deep in the numbers - a good broker improves the odds and manages the process, but does not remove the risk.

Is a business broker worth the commission?

For most owners selling a business in the $500,000-to-$5 million range, the answer is usually yes, especially if the owner doesn't already have a buyer lined up, doesn't have several hours a week to spare for months of marketing and screening, or is selling a business that depends heavily on relationships a broker's network can reach faster than a solo listing. The commission is easiest to justify when a broker's negotiating skill and buyer pool can move the final price up by more than the fee itself - which experienced brokers frequently do, even after accounting for their cut.

The commission is harder to justify on smaller deals under roughly $500,000, where the seller already has a known buyer such as an employee or competitor, or where the business is simple enough - one location, clean books, no complicated licensing - that a motivated owner with some negotiation experience can run the process alone. That's the exact calculation we walk through in how to sell a business without a broker, including the five jobs a seller takes on personally by skipping the fee.

The commission is the cost you can see on the closing statement. A deal that falls apart, drags on for a year, or closes at a lower price than a skilled negotiator would have gotten is the cost you don't see until it's too late to fix.

The bottom line

Business broker fees run 8% to 12% on most Main Street deals under $1 million, drift toward 15% on the very smallest listings, and taper down through a Lehman-style tiered formula as deal size grows past $1 million. A minimum fee, typically $15,000 to $25,000, protects brokers from taking on small deals at a loss. What that money buys is a priced, marketed, negotiated and closed transaction - not a guarantee, but a meaningfully better shot at one. Whether the fee is worth it comes down to deal size, how much of your own time you can spend on the sale, and whether you already have a buyer.
