Capital Calls in VC: Notice Periods, Defaults, Credit Lines

A capital call is a venture fund's formal request for limited partners to wire part of the money they committed. LPs do not pay their full commitment up front: the general partner draws it down in slices over several years to fund investments, follow-ons, fees, and expenses. ILPA recommends giving LPs at least 10 business days to pay each call.

Definition: A capital call (also called a drawdown) is a formal notice from a fund's general partner requiring limited partners to contribute a portion of their committed capital by a stated due date, under the terms of the limited partnership agreement.

A $50M fund rarely has $50M sitting in a bank account. It has $50M of promises.

This guide covers how those promises turn into cash, from the investor's side: commitments, notices, timing, defaults, and subscription credit lines. If you are new to how funds are built, start with the venture capital fund structure guide or limited partner vs general partner.

What a commitment is, and why funds do not collect it up front

A VC fund raises commitments, not cash. The limited partnership agreement (LPA) binds each LP to contribute up to a fixed amount when called.

The GP draws most of that money during the investment period, a median of five years in Carta's Fund Economics Report 2025, and then calls smaller amounts for follow-on investments, fees, and expenses. The venture capital fund lifecycle guide shows where calls fall across a fund's 10-plus years.

Two reasons drive this design. IRR is measured from the date cash leaves the LP's account, so idle cash would drag down returns. And LPs want their money working elsewhere until it is needed.

The scale is large. The SEC's private fund statistics for the fourth quarter of 2025 counted 4,392 venture capital funds with about $705 billion in gross assets, compiled from advisers' Form PF and Form ADV filings, so funds whose advisers file neither are not counted.

How the capital call process works, step by step

The GP identifies a need. A new investment is approved, a follow-on is due, or the management fee and expenses are payable.
The GP checks the LPA. It sets the investment period, concentration limits, what may be called afterward (usually follow-ons, fees, and expenses), and the minimum notice period.
The notice goes out. Each LP receives a written capital call notice. ILPA's Principles 3.0 set a floor of at least 10 business days for LPs to respond, and Carta's capital call guide puts typical transfers at 10 to 14 days. ILPA's 2020 guidance also asks GPs to give as much notice as possible and to share estimates of upcoming calls.
LPs wire funds. Most calls are pro rata: every LP contributes the same percentage of its commitment. An LP with a $1M commitment on a 10 percent call wires $100,000.
The fund administrator reconciles. Contributions are recorded, each LP's remaining unfunded commitment is updated, and capital account statements reflect the new balance.
The GP deploys and follows up. Carta's Fund Economics Report 2025 found that across recent venture vintages at least 75 percent of capital calls are fulfilled at or before the deadline. So GPs can reasonably expect some money to arrive late, and plan closings around it.

What a capital call notice contains

ILPA's Principles 3.0 point GPs to its standardized reporting format for notices. A clear notice typically includes:

The total amount called from the fund and this LP's share.
The purpose, broken into investments (naming the company where permitted), management fees, partnership expenses, and other uses.
The due date and wire instructions.
The LP's commitment, cumulative contributions to date, and remaining unfunded commitment, before and after this call.
Any distributions netted against the call, if the LPA allows netting or recycling.

Watch the unfunded commitment line. It is what you still owe, however the fund is performing.

Capital call schedules: how fast does a fund draw capital?

Carta found that after nearly four years the median 2022 vintage venture fund had deployed 67 percent of its capital, while most other recent vintages had deployed around 80 percent, reflecting a slower deal market for that cohort. Carta also notes that venture capital calls tend to be more frequent but smaller than private equity calls.

An illustrative seed fund schedule (real ones vary): 10 to 25 percent in year one, calls of 5 to 15 percent every quarter or two in years two and three, smaller follow-on calls in years four and five, then occasional calls for fees and expenses.

Management fees are the exception to the rhythm. They are usually called on a fixed schedule regardless of deal activity. Carta reports a median management fee of 2 percent during the investment period, so on a $50M fund charging on commitments that is $1M a year whether or not any deals close. That fixed fee is the heart of our take on carry versus fees: a manager can do fine on the 2 percent even if the 20 percent doesn't arrive. The venture capital management fees guide covers how the fee steps down later.

What happens when an LP misses a capital call

A missed call can force the GP to miss a closing or borrow to cover the gap, so LPAs give the GP escalating remedies. Cooley's primer on capital calls and LP defaults notes that the manager often sends a default notice with a short cure period, usually measured in days rather than months, before more severe remedies apply. After that, the menu usually includes:

Default interest. Cooley notes the rate is often well above the ordinary equalization rate charged at later closings, and the defaulting LP may also have to reimburse enforcement costs.
Forced sale or transfer. The GP can sell the defaulting LP's interest; Cooley calls offering it to the nondefaulting LPs a common approach. Mayer Brown gives a 50 percent discount as an example of the reduced price.
Forfeiture. The GP may cut the defaulter's capital account, by 50 to 100 percent in Mayer Brown's example, or let fees run it down to zero while the LP loses votes and profit allocations.
Withheld distributions. Amounts owed can be set off against future distributions.
Legal action. The GP can sue to enforce the contribution, which Cooley notes still matters when the fund needs the cash rather than a reallocation of economic rights.

The remedies are harsh on paper. In practice, Cooley's primer adds that most capital calls are routine and most investors fund on time. In our view a manager usually does better working with a struggling LP first, for example by helping arrange a transfer of its interest, before reaching for the remedies.

Capital call lines of credit: how they work

Many funds use a subscription (capital call) line of credit: a short-term bank loan secured by the LPs' unfunded commitments. The GP borrows to close a deal immediately and calls capital to repay the bank later. LPs get fewer, more predictable calls, and the GP closes faster.

The concern is performance measurement. Because IRR is clocked from when LP cash goes in, delaying calls with borrowed money can raise reported IRR without changing the cash multiple. Same money back. Better-looking number. ILPA's guidance addresses this in three layers:

LPA limits (Principles 3.0). Lines should be short duration, for example outstanding no more than 180 days, and capped at a percentage of commitments, for example 20 percent.
Disclosure (2020 guidance). Quarterly reporting of the facility size and balance, each LP's unfunded commitment financed through it, the average days outstanding per drawdown, and net IRR with and without the facility, plus annual detail on rates, fees, and terms.
Standard templates (2025). ILPA's updated Performance Template, released in January 2025 with adoption targeted for Q1 2026, breaks out gross and net IRR and TVPI with and without fund-level subscription facilities.

But subscription lines are just good cash management

That's the fair case for them, and some LPs make it themselves. Fewer, larger, predictable calls are easier to plan around than a dozen small ones. A GP who can close a deal this week instead of in ten business days can win allocations. None of that is about gaming IRR.

But.

The same tool that smooths calls can also flatter returns, and from the outside you can't easily tell which one is happening. Our view: a subscription line is a reasonable tool when it is short, capped and disclosed. One without those limits is a reason to ask harder questions. If you are evaluating a fund, ask whether it uses a line, how long borrowings stay outstanding, and whether returns are reported with and without it.

Worked example: a $200K commitment

As an illustrative example, say you commit $200,000 to a $40M seed fund with a 2 percent fee and a 4-year investment period. Your share of the fee is $4,000 a year.

Month 1: first call at 15 percent. You wire $30,000 for early deals, setup costs, and the first fee installment. Unfunded: $170,000.
Months 6 to 36: six further calls of 10 percent each. You wire $20,000 per call, $120,000 in total. Unfunded: $50,000.
Years 4 to 6: three follow-on calls of 5 percent, $10,000 each. Unfunded: $20,000.
Years 7 to 10: the remaining $20,000 is called as needed for fees, expenses, and late follow-ons, partly netted against distributions.

That is more than 10 transfers, each with a due date. It's why many LPs keep a liquidity buffer sized to the calls they expect.

Drawdowns stop being abstract once you are the one holding the buffer.

When calls turn into returns, the carried interest guide explains how the profits are split.

The bottom line

A commitment to a venture fund is a ten-year string of wire requests with a due date on each one. The LPs who have the easiest time are the ones who planned for the calls before the first notice arrived, and who read the fund's credit-line policy as carefully as its fee terms.

Signing the commitment takes an afternoon.

Honoring it takes a decade.

Key takeaways

A capital call draws down part of an LP's commitment; most of it is called during the investment period, a median of five years per Carta.
ILPA recommends at least 10 business days to pay a call, and Carta says transfers typically happen within 10 to 14 days.
Carta found at least 75 percent of capital calls are met at or before the deadline, so GPs plan for some late money.
Default remedies include cure notices, default interest well above normal rates, forced sales, and forfeiture, though most LPs fund their calls on time.
ILPA wants subscription lines limited (for example 180 days, 20 percent of commitments) and returns reported with and without them.

Frequently asked questions

What is a capital call in venture capital?

A capital call is a formal notice from a venture fund's general partner asking limited partners to contribute part of the money they committed to the fund. The notice states the amount, the purpose, and the due date. LPs fund a VC fund through a series of these calls over several years rather than paying their full commitment up front.

How much notice do LPs get for a capital call?

The limited partnership agreement sets the minimum. ILPA's Principles 3.0 recommend at least 10 business days, and Carta says investors typically transfer funds within 10 to 14 days. ILPA's 2020 guidance also asks GPs to give as much notice as possible and to share estimates of upcoming calls.

What happens if an LP cannot meet a capital call?

The GP usually sends a default notice with a short cure period, typically measured in days. If the LP still does not pay, the LPA may allow default interest, a forced sale of the LP's interest at a discount, forfeiture of part or all of its capital account, withheld distributions, or a lawsuit. Most GPs try to work things out first.

How often does a VC fund call capital?

It varies by fund. A seed fund may call capital several times a year during the investment period, then less often for follow-ons, fees, and expenses. Carta found the median 2022 vintage fund had deployed 67 percent of its capital after nearly four years, while most other recent vintages were near 80 percent.

What is a capital call line of credit?

It is a short-term bank loan secured by the LPs' unfunded commitments. The GP borrows to close deals quickly and repays the bank from a later capital call. ILPA recommends limits such as 180 days outstanding and 20 percent of commitments, plus reporting of net IRR with and without the facility.
