Management fee calculation that replays every investor's fee from its clause, before anyone is billed
Every fee recalculated from its clause before billing, every gap explained and signed.
See one case, screen by screen ↓Management fee calculation is working out what each investor in a fund owes the manager each period from the fund's terms: the fee base, the rate after side letters, breakpoints and MFN elections, the days, offsets of portfolio company fees and any late-closer catch-up. Management Fee Calculation gives fund finance six agents that read those terms, recompute every investor's fee independently, compare it with the fund administrator's file step by step and explain each gap, so a person approves every correction before billing.

Management fee calculation looks simple — base times rate times days, less offsets — until you read the terms. The base is commitments during the Commitment Period and net invested capital after it. The rate moves with side-letter breakpoints, affiliate aggregation and MFN elections. Offsets of transaction, monitoring and directors' fees change with each amendment, late closers owe a catch-up from the initial closing, and those terms sit across LPAs, amendments and dozens of side letters, some in German, French or Japanese. The fund administrator calculates and sends a fee file 10 to 15 days after quarter end; fund finance checks totals and a sample in a spreadsheet.
A sample does not catch a term that changes a whole fund. One missed step-down bills every investor in the fund on commitments they no longer pay on. An offset left at the old percentage after an amendment, a breakpoint without aggregation or an MFN election never carried into the fee does the same. In about 130 examinations of advisory fees, SEC staff found fee-calculation deficiencies in most, and in an August 2025 settlement a private equity adviser's double-counted fee offsets ended in a $175,000 penalty plus disgorgement.
Estimated split for one quarter of 40 funds and vehicles, checked by hand and with the solution; the administrator's reply time is part of both.
Six agents read the terms, watch the events, recompute every fee and explain each gap; an analyst prepares, the controller approves.
Quillfield Capital's private markets arm bills Q3 2026 management fees across 40 funds and vehicles and 2,318 investor positions. In Quillfield Growth Partners II, L.P. — 41 fee-paying investors, $1.18 billion of commitments — the Commitment Period ended on June 30. Here is what happens next, screen by screen, in the working solution.
Maya's home screen shows 2,318 positions recalculated from 412 clauses, 142 gaps against the administrator in 6 funds — $1.45M over, $0.55M under — 4 items waiting for her and notices going out Oct 30. First in Needs you: Growth Partners II, step-down not applied, 41 investors, $1,270,020.42 overbilled, corrections prepared by Daniel Okoro at 8:40 a.m. Beside it, what the agents did, every line cited.
Compare agent, Oct 14: “Quillfield Growth Partners II: administrator charged 41 investors on commitments after the Commitment Period. Overbilled $1,270,020.42.”
At 11:59 p.m. on June 30 the Events agent marked the end of the Commitment Period and told the administrator on July 1. On Oct 1 the Calc agent recomputed all 41 positions on net invested capital of $874,861,250: $2,636,267 for Q3. The administrator's file of Oct 14 says $3,906,288. The fund page shows how the fee base moved and every investor's difference.
Compare agent: “We agree on days, rates and offsets and part at step 2, the fee base: the administrator still charges on commitments, which §4.2(b) ends after June 30.”
Calder Bay Public Employees' Retirement System has a $100,000,000 commitment and side letter SL-07. The replay agrees on the day count, 92 ÷ 365, then marks step 2 “They part here”: a fee base of $74,140,783.90, its 8.4746% share of net invested capital, against the administrator's $100,000,000. Rate 1.50% and offsets of −$85,169.49 agree. Net fee $195,143.61 against $292,912.70: $97,769.09 overbilled. Maya asks the agents why; the Compare agent answers with three sources.
“Replays from sealed inputs … Same inputs, same answer, every time.”
Every step carries the clause it rests on and the system each figure came from. LPA §4.2(b) opens on page 38 of the Amended and Restated Limited Partnership Agreement, version 3, with the words the agents used highlighted: from the day after the Commitment Period ends, the fee is 1.75% of each Limited Partner's share of Net Invested Capital.
“The passage is stored with its page, the document version and a fingerprint, so the same words open in the evidence pack.”
Maya approves the 41 corrections with reason code AP-01, “Recalculation agrees with the governing clause”, and an optional note for the record. The screen says who prepared it and who approves it, and that the evidence is sealed with her decision. She could instead return the work with a reason, reject it so the administrator's figure stands, or change any figure an agent used.
“You are Maya Chen; Daniel Okoro prepared it.” Maker and checker stay different people.
The Compare agent compared 2,272 positions in 38 funds: 2,130 agree, 142 differ. Beside the step-down: a late-closer catch-up missing for Marlow Insurance Group ($546,575.35 underbilled), an MFN election not applied, an offset left at 80% when the Second Amendment says 100%, a breakpoint without affiliate aggregation and a write-down not taken out of the base. 460 rounding differences under $25 are cleared on the record under rule TOL-01.
“None is a calculation slip on the administrator's side; all six are terms their tables did not have.”
Versorgungswerk Nordmark wrote on Sep 2 to elect the 1.25% rate in side letter SL-QIP1-11, effective January 1, 2026. The Terms agent shows the German original — the governing text — beside the English, reads three fee terms at 95–97% confidence and Owen Pryce confirms them. The administrator still charges 1.40%: €22,684.93 too much for Q3, with a credit note of €44,630.14 for Q1–Q2.
Terms agent: “The original governs.”
Brightwell Dental Partners was written down $18.0M on Aug 14, and the Growth Partners I LPA reduces the base only for a write-down that is “permanent”. The Calc agent computed both readings: $41,424.72 overbilled across 34 investors if it is permanent. Its confidence is below 90%, so Maya records interpretation INT-006 once, for all 4 funds with the same wording, and Lena Whitcombe, Chief Compliance Officer, is informed.
Calc agent: “I computed it both ways … a person decides.”
The Notice agent drafts all 2,318 notices from approved figures: 2,130 ready, 142 held until approved, one credit note. Versorgungswerk Nordmark's notice is in German, with one line on why the rate is 1.25%. The 41 Growth Partners II notices say: “From July 1, 2026 your management fee is charged on your share of net invested capital, as Section 4.2(b) provides.” Only investor relations sends, and only approved notices.
The Marlow Insurance Group catch-up bills an investor more, so after Maya it goes to Robert Lindqvist for the second approval. The Q3 sign-off is due by Oct 28 and opens only when all 6 funds with gaps are decided. Robert then confirms that every fee was recalculated from its governing terms and every difference decided by someone other than its preparer.
“… and no notice is released before this sign-off.”
The same Q3 fee run, seen by five of the people who carry it — what the quarter looked like, and what it looks like now.
Six agents read the terms, watch the events, recompute every fee and explain each gap; an analyst prepares, the controller approves.
Reads every LPA, amendment, side letter, MFN notice and election in its original language and keeps one fee term table per fund and investor — base, rate, step-down trigger, offsets, breakpoints, aggregation, catch-up and day count — each term cited to its clause and page.
Watches for what changes a fee before the quarter closes: the end of a Commitment Period, a successor fund's first fee, write-downs, dispositions, transfers, late closers and MFN elections. It drafts the notice to the administrator 30 days ahead and re-runs the fees on the day.
Recomputes every investor's fee independently, step by step from the governing clause: period and day count, base, rate, side-letter adjustments, gross fee, offsets, catch-ups and earlier-quarter credits, with every input's source recorded.
Reconciles every position with the administrator's fee calculation file, finds the first step where the two calculations part and explains the cause with its clause.
Drafts fee notices, credit notes, administrator queries and investor replies in plain words and in the investor's language, from approved figures only.
Seals every input, agent statement and decision with its source and a hash, and builds the examiner and auditor pack: replays, clauses, decisions and agent statements with their model and prompt versions.
Maker, checker, sign-off, send. The agents propose; a named person decides.
Ask about any fund, investor, clause or deadline, or tell the agents what to do. They answer with sources and act only with a person's approval.
Why is Growth Partners II overbilled?
The Commitment Period ended on June 30, 2026, and from July 1 the fee is charged on Net Invested Capital. The administrator kept charging on $1,180,000,000 of commitments instead of $874,861,250: $1,270,020.42 overbilled across 41 investors. Opening the replay for Calder Bay.
Did the Lux parallel fund get it right?
Yes. Quillfield Growth Partners II (Lux) SCSp has the same clause, and its administrator moved to Net Invested Capital on July 1. All 29 positions agree within the $25 tolerance.
Which funds step down in the next 12 months?
Three: Quillfield Asia Growth Fund I on Dec 15, 2026, Quillfield Healthcare Partners I on Mar 31, 2027 and Quillfield Secondaries Opportunities II on Jun 30, 2027. The Events agent tells each administrator 30 days ahead and re-runs the fees on the day.
What must be approved before notices go out on Oct 30?
Three corrections wait for Maya Chen — Growth Partners II, Infrastructure Partners I and the Marlow catch-up, which also needs the CFO — one interpretation for Growth Partners I, and two corrections still to prepare. Then Robert Lindqvist signs the quarter.

Management fee calculation is working out what each investor in a fund owes the manager each period from the fund's terms: the fee base, the rate after side letters, breakpoints and MFN elections, the days, offsets of portfolio company fees and any late-closer catch-up. Management Fee Calculation gives fund finance six agents that read those terms, recompute every investor's fee independently, compare it with the fund administrator's file step by step and explain each gap, so a person approves every correction before billing.
The usual management fee calculation formula is fee base × rate × days in the period, less offsets. Many LPAs charge on commitments during the Commitment Period and step the base down to net invested capital after it. In the working solution's example the step-down applies from the day after the Commitment Period ends: $74,140,783.90 × 1.50% × 92 ÷ 365 gives a gross fee of $280,313.10, and offsets of $85,169.49 leave a net fee of $195,143.61. Each step is shown with the clause it rests on.
A management fee offset reduces the fee by a share of the transaction, monitoring and directors' fees the manager receives from portfolio companies, at the percentage the LPA or a later amendment sets. The Calc agent applies the percentage in force; in Quillfield Private Credit Fund III the administrator offset 80% of a $324,000 transaction fee where the Second Amendment says 100%, and the Compare agent showed the $64,799.96 overbilled across 63 investors, with the amendment cited.
The Compare agent runs the management fee reconciliation position by position: it matches every investor to the administrator's file, finds the first step where the two calculations part and explains the cause with its clause. It clears only rounding differences under $25, logged with both figures. A file with rows that cannot be matched to the investor register is set aside whole, and a query with the clause and the per-investor schedule is drafted for an analyst to send.
Yes. In the working solution the Terms agent has read 412 fee documents in 5 languages, and shows a German or French original beside its English reading; the original governs. Any term read below 90% confidence goes to an analyst with the passage — a low-resolution French scan read at 62% was confirmed from the signed original.
The Reports screen shows gross-to-net management fees by strategy — gross fee, offsets and net fee — in ILPA Reporting Template v2.0 lines, from the solution's own recalculation, with four quarters of differences from the administrator beside them. The fee run also exports an ILPA gross-to-net management fee reconciliation as a spreadsheet.
Yes. The agents recompute, compare and draft; they never approve, send, bill or change a term. An analyst prepares each correction, the fund controller approves it with a reason code, the CFO gives a second approval at $250,000 or more and on undercharges and signs the quarter, and investor relations sends only approved notices.
The Agentic Solution Engine builds and deploys it from your requirements and documents — your LPAs, side letters and past administrator files — and it goes live once every quality gate has passed.
