M&A Advisor Fee Cap vs Minimum Fee

A fee cap and a minimum fee work in opposite directions. A fee cap limits what the seller pays as transaction value rises. A minimum fee creates a floor below which the advisor’s fee will not fall. Sellers should understand both before signing an engagement letter.

Lyndon Advisory charges 2% of enterprise value, capped at US$300,000, with no retainer, monthly fee, or expense recharge. For the broader owner path, read Lyndon’s selling a business guide before comparing fee mechanics in isolation.

Fee Cap vs Minimum Fee

Term	What it does	Who it protects most
Fee cap	Sets maximum advisory fee	Seller
Minimum fee	Sets minimum advisory fee	Advisor
Retainer	Pays advisor before closing	Advisor cash flow
Expense recharge	Passes process costs to seller	Advisor margin
Closing-only trigger	Fee due only at completion	Seller alignment

Axial’s 2025-2026 M&A Fee Guide discusses minimum fees, retainers, success-fee formulas, and expense policies across lower-middle-market mandates. The same headline percentage can produce very different outcomes depending on caps and minimums.

Why the Difference Matters

Enterprise value	2% uncapped	2% capped at US$300,000	Effective capped rate
US$10M	US$200,000	US$200,000	2.00%
US$15M	US$300,000	US$300,000	2.00%
US$25M	Higher than cap	US$300,000	1.20%
US$50M	Higher than cap	US$300,000	0.60%
US$100M	Higher than cap	US$300,000	0.30%

The cap becomes more valuable as transaction size increases. A minimum fee has the opposite effect: it matters most when the transaction size is smaller and the formula would otherwise produce a lower dollar amount.

CFI’s Lehman Formula overview explains how tiered success fees can be calculated. Whether the formula is flat, tiered, capped, or subject to a minimum, the seller should translate it into expected dollars.

“A fee cap makes the economics legible for the seller. A minimum fee may be commercially reasonable in some mandates, but it should never be hidden inside a percentage discussion.”

— Daniel Bae, Founder & CEO, Lyndon Advisory

Seller Checklist

Before signing, ask:

• Is there a stated maximum fee?
• Is there a minimum fee?
• Is the fee calculated on enterprise value or equity value?
• Is any retainer credited against the success fee?
• Are expenses recharged?
• Is the success fee payable only at closing?
• Does the tail clause apply only to named, substantively contacted buyers?
