Retainer: $10K to $25K a month, or $50K to $100K upfront. Retainers run in this range across the engagement letters Cooley reviewed (October 2026), paid regardless of outcome. Most agreements credit the retainer against the success fee; how and when it is credited is negotiated (Cooley, October 2026; Mayer Brown, April 2025).
Success fee on committed capital: About 1% to 2.5%. Most often 1.5% to 2%. Calculated on new LP commitments introduced by the agent (Cooley, October 2026). On a $200MM raise where the agent introduces $150MM in new capital, a 2% fee is $3MM. At 2.5%, $3.75MM. First-time and smaller funds pay a premium: 2.5% to 3%, sometimes more on hard raises.
Payment: 1 to 4 years of installments. The success fee is charged once per commitment, unlike the ongoing fees some hedge funds pay (Morgan Lewis). It is almost never paid at closing: agreements spread it over 4 to 16 quarters, with interest on the unpaid balance at 2.5% to 5% in the agreements Cooley reviewed. Newer agent letters also reach into the next fund: one from 2025 charges 0.50% on investors the agent introduced who re-up into the successor fund (Cooley, October 2026).
Tail provision: Most often 12 months. Sometimes 18. Twelve months is the most common tail in fund agreements, with 18 appearing (Cooley, October 2026); across engagement letters for private placements generally, tails run 12 to 24 months (Mayer Brown, April 2025). If any LP the agent introduced during the engagement commits capital during the tail window, even after the agent is no longer working for you, you owe the full success fee on that commitment. An investor the agent met who commits 14 months after you terminate falls inside an 18-month tail but outside a 12-month one.
Total cost on a $200MM raise: $3MM success fee; a $180K retainer ($15K a month for a year) is credited against it = $3MM, paid in installments with interest. That comes directly from management fees the GP would otherwise retain. On a 2% management fee generating $4MM a year, $3MM is about nine months of management fees, and $3.75MM at 2.5% about 11 months. Cooley's own example: on a $400MM fund at 2%, the fee is $8MM, roughly one year of management fees (Cooley, October 2026). For Fund I managers, that burden is even more punishing relative to the smaller fee base.
