Average Business Broker Commission and Fees in 2026 (And How to Pay Less)

The average business broker commission, 8 to 12 percent of the sale price, is the largest single cost most sellers face, and it’s the cost most sellers never question. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing.

Average commission by deal size

The pattern: smaller deals pay a higher percentage (the work doesn’t shrink proportionally with deal size), and the minimum fee can be the real number on the smallest deals.

What a ‘Lehman scale’ means

The classic Lehman formula: 5% on the first $1M, 4% on the second $1M, 3% on the third $1M, 2% on the fourth $1M, 1% on everything above $4M. In practice, lower-middle-market business brokers and M&A advisors use modified-Lehman scales that start higher, commonly something like 10% on the first $1M, 8% on the second, 6% on the third, 4% on the fourth, and 2-3% above, sometimes with the percentages or the tiers adjusted. The point of a tiered scale is that the percentage decreases as deal size grows, which roughly reflects that a $10M deal isn’t 10x the work of a $1M deal. Always confirm the exact tiers and percentages in writing, ‘a Lehman scale’ isn’t precise enough.

The fine print that affects the real cost

• Minimum fee. Commonly $15,000-$50,000 regardless of sale price. On a small deal, the minimum often is the commission, a $200K sale with a $25K minimum is effectively a 12.5% commission. Confirm the minimum.
• Retainer (engagement fee). Lower-middle-market M&A advisors often charge a monthly retainer ($2,500-$10,000) during the engagement, usually credited against the eventual success fee. If the deal closes, you net it out; if it doesn’t, you’ve paid the retainers for nothing. Confirm whether the retainer is creditable and refundable.
• Tail provision. After the engagement ends, the broker is typically still owed a fee for some period (commonly 12-24 months) if you close with a buyer the broker introduced (or sometimes even contacted) during the engagement. Read this carefully: which buyers count, and for how long? An overly broad tail can mean owing a commission on a deal you sourced yourself.
• Definition of ‘sale price’ / ‘transaction value.’ Does the commission apply to the headline price, or to total consideration including assumed debt, earnouts, rollover equity, seller notes, and consulting payments? A broad definition increases the fee. Clarify.
• Exclusivity and term. Most engagements are exclusive (you can’t use another broker) for 12 months, sometimes auto-renewing. Confirm the term and renewal mechanics.
• Expenses. Are out-of-pocket expenses (marketing, data room, travel) billed separately on top of the commission? Often yes; confirm.

M&A advisor, buy-side, and referral fees

Not every intermediary in a business sale is a main street broker, and the fee structures differ.

M&A advisor fees. Above roughly $1M of sale price, sellers usually hire an M&A advisor instead of a listing broker. The fee is a success fee on a tiered scale plus, often, a monthly retainer. Axial’s survey of M&A advisors and brokers found that 65% set their monthly retainer at $5,000 to $10,000. Ask whether the retainer is credited against the success fee and what happens to it if no deal closes. For a side-by-side of broker and advisor pricing, see our guide on how much a business broker charges.

Buy-side business broker fees. A buy-side broker or advisor works for the buyer: finding targets, approaching owners, and running the deal. The buyer pays, usually through a retainer, a success fee tied to the purchase price, or a flat finder’s fee. A seller still needs to know who pays whom, because a buyer’s advisor fee comes out of the buyer’s total budget for the deal.

Business broker referral fees. A referral fee is a share of the broker’s commission paid to whoever sent the seller to the broker, such as another broker, an accountant, or a banker. It is set in a written referral agreement between the broker and the referrer. It should come out of the broker’s commission, not add to your cost. Ask any broker you interview to disclose referral arrangements in writing before you sign.

How to pay less

• No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. For businesses with $1M+ EBITDA, the realistic buyer pool, strategic acquirers, PE-backed platforms, family offices, routinely pays sell-side advisor fees as a normal transaction cost. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. This is the structural way to take the cost to zero, not a discount. See our broker alternative guide.
• Negotiate the structure, not just the percentage. Smaller-business brokers tend to have set commission rates and minimums; lower-middle-market advisors are more flexible on structure, push for a lower (or no) retainer, a shorter tail, a tighter definition of covered buyers, a lower minimum, or a lower percentage on the upper tiers.
• Narrow the tail. Negotiate which buyers count (only those the broker actually introduced, documented in writing) and a shorter tail period (12 months rather than 24).
• Tighten the ‘transaction value’ definition. Limit the commission to cash consideration, or exclude assumed debt, contingent earnouts, and consulting payments.
• Consider direct-to-known-buyer if you have one. If there’s already a logical buyer (a competitor, supplier, partner, key employee), you can negotiate directly with just a transactional attorney, no broker commission at all, though you give up the competitive-process leverage a broker (or advisor) provides.
• Don’t choose on commission alone. The advisor who pays for themselves in leverage (a higher price, better terms, a faster close) often costs less in absolute dollars than the cheaper one who doesn’t.

Average Business Broker Commission: Frequently Asked Questions

What is the average business broker commission?

Roughly 8 to 12 percent of the sale price for businesses under about $1 million, paid by the seller at closing, with the smallest deals sometimes 12 to 15 percent (or effectively higher, when a minimum fee of $15K-$50K dominates). Lower-middle-market deals (~$1M-$25M) more often use a Lehman or modified-Lehman tiered scale (decreasing percentage as the deal grows) plus a monthly retainer of $2,500-$10,000 credited against the success fee. There’s also typically a tail provision keeping the broker owed a fee for 12-24 months after the engagement ends if you close with an introduced buyer.

Is a 10% business broker commission normal?

Yes, 10% is squarely in the normal range for a business sale under about $1 million, the typical band is 8-12%, and 10% is right in the middle. For larger lower-middle-market deals, the blended rate usually comes down (via a Lehman/modified-Lehman tiered scale), and a monthly retainer is more common. On very small deals, the effective rate can exceed 10% because the minimum fee (often $15K-$50K) becomes the binding number. Always confirm the exact structure, percentage, minimum, retainer, tail, and ‘transaction value’ definition, in writing.

What is a Lehman fee scale?

A tiered commission structure where the percentage decreases as the deal size grows. The classic Lehman formula is 5% on the first $1M, 4% on the second, 3% on the third, 2% on the fourth, 1% above $4M. In practice, lower-middle-market business brokers and M&A advisors use ‘modified-Lehman’ scales that start higher, commonly around 10% on the first $1M, 8% on the second, 6% on the third, and so on. The rationale: a $10M deal isn’t 10x the work of a $1M deal. Always confirm the exact tiers and percentages, ‘a Lehman scale’ isn’t precise enough.

How can I reduce the business broker commission?

No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. Beyond that: negotiate the structure (lower or no retainer, shorter tail, tighter definition of covered buyers, lower minimum, lower percentage on upper tiers); tighten the ‘transaction value’ definition (limit the commission to cash consideration); or, if you have a known buyer already, negotiate directly with just a transactional attorney and no broker commission at all (though you give up the competitive-process leverage).

Who pays the business broker commission?

In a traditional brokerage transaction, the seller pays, typically 8-15% of the sale price, at closing from proceeds. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing.

What is a tail provision in a broker agreement?

A clause keeping the broker owed a commission for some period after the engagement ends (commonly 12-24 months) if the seller closes with a buyer the broker introduced, or sometimes even contacted, during the engagement. The rationale is that the broker shouldn’t lose a fee just because a buyer they sourced takes a while to close. The risk: an overly broad tail can mean owing a commission on a deal you actually sourced yourself. Read it carefully, negotiate which buyers count (only those the broker actually introduced, documented in writing) and a shorter tail period.

Is the business broker commission negotiable?

Sometimes, more often the structure than the percentage. Smaller-business brokers tend to have set commission rates and minimums; lower-middle-market M&A advisors are more flexible, you can often negotiate a lower or eliminated retainer, a shorter tail, a tighter definition of covered buyers, a lower minimum, a lower percentage on the upper tiers, or a tighter ‘transaction value’ definition (excluding assumed debt, earnouts, consulting payments). No fee to you on buy-side introductions; sell-side mandates are paid on success at closing.

How much will I actually pay a business broker on a $2 million sale?

Roughly $120,000 to $200,000 if it’s a flat 6-10% (the typical blended range at that size), or somewhat less if a modified-Lehman scale is used (e.g., $180K under a 10%/8%/6% scale: 10% of the first $1M plus 8% of the second $1M, per the modified-Lehman formula above). Add any out-of-pocket expenses billed separately, and net out any retainers already paid (if creditable). No fee to you on buy-side introductions; sell-side mandates are paid on success at closing. Confirm the exact structure in writing before signing.

What is a business broker referral fee?

It is a share of the broker’s commission paid to the person who referred the seller, often another broker, an accountant, or a banker. The split is set in a written referral agreement between the broker and the referrer. It should come out of the broker’s commission, so it does not raise your cost. Ask the broker to disclose any referral fee in writing.

How much does a buy-side business broker charge?

The buyer pays a buy-side broker or advisor, not the seller. Common structures are a monthly retainer, a success fee tied to the purchase price that often steps down on a tiered scale like the Lehman formula, or a flat finder’s fee. Terms vary widely, so buyers should confirm the retainer, the success fee, and what counts as a closed deal in writing.

Do M&A advisors charge more than business brokers?

In dollars, usually yes, because they handle larger deals. As a percentage, usually no. Main street brokers on small deals charge a flat percentage of the price, while M&A advisors on larger deals use a tiered success fee that falls as the price rises, often with a monthly retainer. Compare the total dollar cost, not the headline percentage.
