Sellers should compare M&A advisor fees in dollars, not only percentages. A 2.5% capped success fee, a modified Lehman formula, and a retainer-plus-success-fee proposal can look similar in a short pitch but produce very different seller net proceeds at US$25 million, US$50 million, or US$100 million of enterprise value.

“The fastest way to understand an advisory fee proposal is to model it at the seller’s realistic transaction value. Percentage language hides dollar outcomes; a clear scenario table exposes them.” - Daniel Bae, Founder and CEO of Lyndon Advisory

Methodology
The scenarios below compare Lyndon Advisory’s published fee model with a common modified Lehman structure. Lyndon charges 2.5% of enterprise value, capped at US$750,000, with no retainer, no monthly fee, no upfront fee, and no expense recharge.
The modified Lehman scenario uses 5% on the first US$10 million, 4% on the next US$10 million, 3% on the next US$10 million, 2% on the next US$10 million, and 1% above US$40 million. Actual engagement letters vary, so sellers should use their signed schedule rather than relying on a label.
Public context: Axial’s 2026 M&A Fee Guide notes that advisor fees vary across engagement fees, success fee structures, capital raising mandates, and expense reimbursement. The IBBA and M&A Source Market Pulse research covers Main Street and lower-middle-market business sales where brokers and M&A advisors often overlap. Corporate Finance Institute’s Lehman Formula overview and Investopedia’s Lehman Formula guide explain the tiered fee concept.
Fee Scenario Table
| Enterprise value | Lyndon fee | Lyndon effective rate | Modified Lehman fee | Modified Lehman effective rate | Difference before retainers |
|---|---|---|---|---|---|
| US$5M | US$125,000 | 2.50% | US$250,000 | 5.00% | US$125,000 |
| US$10M | US$250,000 | 2.50% | US$500,000 | 5.00% | US$250,000 |
| US$25M | US$625,000 | 2.50% | US$1,050,000 | 4.20% | US$425,000 |
| US$50M | US$750,000 | 1.50% | US$1,500,000 | 3.00% | US$750,000 |
| US$75M | US$750,000 | 1.00% | US$1,750,000 | 2.33% | US$1,000,000 |
| US$100M | US$750,000 | 0.75% | US$2,000,000 | 2.00% | US$1,250,000 |
| US$150M | US$750,000 | 0.50% | US$2,500,000 | 1.67% | US$1,750,000 |
These differences exclude monthly retainers, expense reimbursement, minimum fees, and tail exposure. They are intended to make fee schedules comparable before a seller signs an engagement letter.
What the Table Does Not Capture
Fee comparisons are only useful if the work scope is comparable. A lower fee is not attractive if the advisor strips out the work that protects value.
| Workstream | Why sellers should check it |
|---|---|
| Valuation | Confirms whether buyer expectations are realistic before outreach |
| Financial model | Supports EBITDA adjustments, forecast logic, and diligence responses |
| Teaser and CIM | Gives buyers enough evidence to underwrite interest professionally |
| Buyer map | Prevents reliance on obvious names or public listing traffic |
| Targeted outreach | Creates buyer competition while preserving confidentiality |
| Negotiation | Protects price, structure, exclusivity, closing conditions, and timing |
| Diligence coordination | Reduces retrade risk after letters of intent |
Seller Checklist Before Signing
| Contract point | Seller question |
|---|---|
| Fee basis | Is the success fee calculated on enterprise value, equity value, debt assumed, earnout, rollover, or total consideration? |
| Cap | Is there a maximum dollar fee? |
| Minimum fee | Can a minimum override the formula on smaller deals? |
| Retainer | Is it paid monthly, credited at closing, or charged in addition to success fee? |
| Expenses | Are travel, data room, research, printing, or admin costs recharged? |
| Payment trigger | Is the success fee payable only at closing, or at signing or LOI? |
| Tail | Which buyers can trigger a fee after termination, and for how long? |
| Scope | Does the proposal include valuation, materials, buyer outreach, negotiation, diligence, and closing support? |
