Business brokers typically charge a commission of 5% to 12% of the final sale price, with the exact percentage depending largely on the size of the deal. Smaller businesses pay rates at the higher end of that range, while larger transactions command lower percentages. Beyond the success fee, some brokers also charge upfront retainers, valuation fees, or marketing costs that add to the total bill.
How the Commission Percentage Works
The standard business broker commission is a “success fee,” meaning you only pay it when the sale closes. For most small businesses selling for under $1 million, expect the commission to fall between 8% and 12%. As the sale price climbs, the percentage generally drops. A business selling in the $1 million to $5 million range might see rates closer to 5% to 8%.
Many brokers use a tiered structure rather than a single flat percentage. Under this approach, different portions of the sale price are charged at different rates. A common example looks like this:
- First $500,000: 15%
- $500,000 to $1 million: 10%
- $1 million to $5 million: 5.5%
To see how this plays out in practice, consider a business that sells for $700,000. Under a tiered structure like the one above, the broker would charge 15% on the first $500,000 ($75,000) plus a lower rate on the remaining $200,000, bringing the total fee to roughly $91,000. That works out to about 13% of the sale price, which is higher than a flat 10% rate would produce on the same deal. The tiered model rewards brokers for getting deals done at smaller price points, where the work involved can be just as intensive as a larger sale.
Minimum Fees for Small Deals
If your business sells for a relatively low price, a percentage-based fee might not be enough to justify the broker’s time. Most brokers set a minimum success fee, typically between $10,000 and $25,000. So even if 10% of your sale price would only amount to $7,000, the broker’s contract will specify a floor. This is worth asking about upfront, because on a very small transaction, the minimum fee can represent a much larger effective percentage than you’d expect.
The Lehman Scale for Larger Deals
Once a business sale crosses into the multimillion-dollar range, you’re more likely to work with an M&A (mergers and acquisitions) advisor than a traditional business broker. M&A advisors handle deals that typically start at $2 million and go well above that. Their fee structures often follow the Lehman Formula, a tiered commission model that originated in investment banking:
- First $1 million: 10%
- Second $1 million: 8%
- Third $1 million: 6%
- Fourth $1 million: 4%
- Everything above $4 million: 2%
On a $5 million deal, the Lehman scale produces a total fee of $380,000, which works out to 7.6% of the sale price. The declining tiers mean that as the deal grows, the blended rate keeps falling. M&A advisors also tend to set higher minimum fees than business brokers, generally between $35,000 and $50,000, reflecting the complexity of larger transactions.
Upfront Fees and Retainers
Not every dollar you pay a broker comes out of the sale proceeds. Some brokers charge fees before the deal even closes. These can include a business valuation fee to determine your asking price, a marketing or listing fee to cover advertising costs, or a monthly retainer to compensate the broker for ongoing work while searching for buyers. These upfront costs vary widely from broker to broker. Some charge nothing beyond the success fee, while others require several thousand dollars before any work begins.
When evaluating a broker’s fee structure, ask whether upfront payments are credited against the final commission or treated as separate charges. A broker who collects a $5,000 retainer and then charges 10% at closing is more expensive overall than one who charges 10% with no retainer, even though the commission rate looks identical. Get the full picture in writing before signing an engagement letter.
What Affects Your Total Cost
Several factors push broker fees higher or lower beyond just the sale price. Businesses that are harder to sell, whether because of inconsistent financials, niche industries, or owner-dependent operations, may command higher commission rates because the broker expects a longer, more difficult process. A well-documented business with clean books, diversified revenue, and transferable operations is a more attractive listing, and you may have more room to negotiate the rate.
Exclusivity matters too. Most brokers require an exclusive listing agreement for a set period, often six to twelve months. During that window, the broker earns the commission regardless of who finds the buyer, even if you bring them yourself. Non-exclusive arrangements exist but are less common, and brokers may charge higher rates or require larger retainers to offset the risk of doing work without a guaranteed payout.
Geography and local market conditions also play a role. In areas with more brokers competing for listings, you may find more flexibility on fees. In thinner markets, brokers have less incentive to discount. The best leverage you have is a business that’s genuinely ready to sell: organized financials, a realistic asking price, and a clear reason a buyer would want it.
How to Compare Broker Fees
When interviewing brokers, ask each one to walk you through the total fee structure in a concrete scenario. Give them your expected sale price and ask what you’d pay in total, including any upfront charges, the commission calculation, and whether there are additional costs for things like legal document preparation or buyer screening. Comparing brokers on commission rate alone can be misleading if one charges a flat 10% with no extras while another charges 8% plus a $3,000 retainer and a $2,000 marketing fee.
Pay attention to how the commission is calculated, too. Most brokers base their fee on the total sale price, but some calculate it on the “enterprise value,” which can include assumed debt and other adjustments that make the number larger. A 10% fee on enterprise value produces a bigger bill than 10% of the cash you actually receive at closing. Read the engagement agreement carefully and make sure you understand which number the percentage applies to.
