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

Quick Answer

The average business broker commission in 2026 is 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 at 12 to 15 percent. Lower-middle-market deals (roughly $1M to $25M) more often use a Lehman or modified-Lehman tiered scale that decreases as the deal grows, for example 10 percent on the first $1M, 8 percent on the second, 6 percent on the third, and so on, often combined with a monthly retainer of $2,500 to $10,000 that is credited against the success fee. Most brokers also set a minimum fee, commonly $15,000 to $50,000, regardless of sale price, and a tail provision that keeps the broker owed a fee (typically for 12 to 24 months after the engagement ends) if the seller closes with a buyer the broker introduced. The biggest way to pay less: the buyer-paid sell-side advisor model, where the buyer pays the advisory fee at closing instead of the seller, so the seller pays nothing, this works for businesses with $1M+ EBITDA where the realistic buyer pool (strategic acquirers, PE-backed platforms, family offices) routinely pays advisor fees.

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. This page lays out what’s typical (by deal size, by fee structure), what the contract fine print actually means (minimums, retainers, tails), and the one move that can take the seller’s advisory cost to zero: the buyer-paid sell-side model.

What this guide covers

Under ~$1M: typically 8-12% of sale price (smallest deals sometimes 12-15%), paid by the seller at closing
~$1M-$25M: often a Lehman or modified-Lehman tiered scale (decreasing as the deal grows) plus a $2,500-$10,000 monthly retainer credited against the success fee
Minimum fee: commonly $15,000-$50,000 regardless of sale price
Tail provision: the broker is owed a fee for ~12-24 months after the engagement ends if you close with an introduced buyer
The buyer-paid alternative: the buyer pays the advisory fee at closing, so the seller pays nothing, works for $1M+ EBITDA businesses
Negotiable: the structure (more than the percentage), retainer, tail length, what counts as a covered buyer, minimum

Average commission by deal size

Sale price	Typical commission structure	Effective rate
Under $250K	Flat percentage, often with a minimum that dominates	12-15%+ (the minimum fee, often $15K-$25K, is the binding number)
$250K-$1M	Flat percentage, 8-12%	~8-12%
$1M-$5M	Flat 8-10%, or a Lehman/modified-Lehman scale, sometimes plus a retainer	~6-10% blended
$5M-$25M	Modified-Lehman scale plus a monthly retainer credited against success fee	~3-7% blended
$25M+	Lower-percentage scale, larger retainer; investment-bank territory	~1-4% blended

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.

How to pay less

The biggest move: the buyer-paid sell-side model. 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. A sell-side advisor whose fee is structured to be paid by the buyer at closing means the seller pays nothing in advisory fees. 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.

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?

The biggest move is the buyer-paid sell-side model, for businesses with $1M+ EBITDA, the buyer pays the advisory fee at closing instead of the seller, so the seller pays nothing in advisory fees. 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. There’s a structural alternative, the buyer-paid sell-side advisor model, where the buyer pays the advisory fee at closing instead. The buyer-paid model is most common in the lower middle market with strategic acquirers and PE-backed platform buyers, who routinely pay sell-side advisor fees as a normal transaction cost; it’s less common in very small businesses sold to individual SBA-financed buyers, who can’t absorb advisor fees.

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). The biggest ‘negotiation,’ though, is choosing the buyer-paid model where it applies, that takes the seller’s advisory cost to zero rather than just reducing it.

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., ~$160K-$180K under a 10%/8%/6% scale on the first three $1M tranches, ignoring the partial third tranche). Add any out-of-pocket expenses billed separately, and net out any retainers already paid (if creditable). With the buyer-paid sell-side model, the seller’s advisory cost on the same $2M deal is $0, the buyer pays the advisory fee at closing. Confirm the exact structure in writing before signing.
