You read that a firm closed a new $400 million fund and picture the money sitting in an account, ready to wire. Committed capital reaches the fund in stages, and about a third of what venture funds have raised is still undeployed. Investors in the fund pledge a total up front and send it in installments through a mechanism called a capital call.

This guide covers what a capital call is, how the process runs from commitment to wire and what the timing means for founders raising now.

What Is a Capital Call

A capital call is a formal request from a fund's general partner (GP) asking limited partners (LPs) to transfer a portion of the capital they already agreed to commit. GPs also call it a drawdown, and it carries legal force once an LP signs on. The limited partnership agreement (LPA) sets the notice period, the calculation method and the consequences of failing to fund. Capital calls involve three core terms:

• Committed capital: The total an LP pledges to contribute over the fund's life. Announced fund size is the sum of these pledges across all its investors.
• Paid-in capital: The running total of contributions an LP has completed. Fund reports refer to the same figure as the cumulative takedown amount.
• Unfunded commitment: Committed capital minus paid-in capital, also called uncalled capital. Dry powder is the related term for committed capital a fund has not yet invested.

Each capital call converts a slice of unfunded commitment into paid-in capital without changing the LP's total commitment. Someone who has wired $40 million of a $100 million commitment still has $60 million left to fund.

How Capital Calls Work in Venture Capital

The process follows a sequence the LPA locks in before the fund makes its first investment. An LP commits at closing, the GP sends a notice when it needs cash, the LP wires within a set window and the fund puts the money to work.

The Capital Commitment

LPs sign a legally binding commitment at the fund's closing, and the fund records the subscription. Cash stays in the investor's own accounts until called. Signing does not itself require a wire unless the fund issues a closing capital call.

That first call often follows shortly after the initial closing and can draw down only part of the fund. GPs can call capital for new investments during the investment period, typically the fund's early years. Later calls are limited to follow-ons, fees and existing obligations.

The Capital Call Notice

When the GP approves a deal or needs to cover fees, the fund issues a formal notice to every LP. It states the amount due, the purpose of the call, the due date and wire instructions, along with the LP's remaining unfunded commitment after the call.

Preparation often falls to the GP working with a third-party fund administrator. Administrators calculate each LP's allocation and track payments as they arrive. Allocation usually follows the pro rata method the LPA specifies. An LP who committed $10 million to a $100 million fund owes $200,000 of a $2 million call.

The Funding Window

Notice periods live in the LPA rather than in market habit. Industry model terms put the floor at 10 business days between a drawdown notice and its due date, and individual funds write their own terms above that floor. LP-side wiring can add more time, especially if investors need to liquidate assets before they can fund.

The Capital Deployment

Fund administrators reconcile each payment against the notice once the wires arrive, then confirm receipt to the LP. Money then goes where the notice said it would: your round, a follow-on check, management fees or fund expenses. Bookkeeping follows the wire: the fund records each contribution, updates every capital account and reduces each LP's unfunded commitment by the amount funded.

When and How Often Funds Call Capital

Capital calls cluster in a fund's early years, when the GP is still making new investments and paying management fees. Five vintages raised between 2021 and 2025 accounted for nearly all the capital called across the venture benchmark for the first half of 2025. After the investment period ends, the pace falls off sharply.

Fund strategy sets the drawdown pace. Seed funds write many small checks and call cash in steady increments. Larger funds write bigger, later stage checks that take longer to close, and their calls arrive less often. Cadence is a relationship decision as well: LPs plan liquidity around those wires, and many GPs flag a deal informally or set a quarterly schedule.

What Happens When an Investor Misses a Capital Call

An LP commitment is a binding contract. Every LPA spells out what happens when the wire doesn't arrive, in escalating order:

• Cure period and penalty interest: The fund issues a default notice and gives the LP a contractual cure window, with interest accruing on the late amount. Funding inside the window, interest included, can restore good standing.
• Capped participation: After the cure period lapses, the GP can reduce or eliminate the LP's remaining commitment and strip its voting and consent rights. Other LPs then absorb the shortfall and see their percentage interests rise.
• Reduced or suspended distributions: Agreements commonly let the fund withhold distributions the defaulting LP would otherwise receive and apply them against the unpaid balance.
• Forfeiture or forced sale: State partnership law lets an agreement dilute the defaulting LP's stake, force a sale of the position or eliminate it outright. Some agreements set that sale price by appraisal or formula at a fraction of the interest's value.

Default remedies can wipe out everything an LP has already paid in, gains included. Serious defaults stay rare in institutional venture funds.

How Capital Call Lines of Credit Work

A capital call line of credit, or subscription facility, is a short-term loan secured by the fund's uncalled LP commitments. Banks extend it so a fund can cover a deal before LP cash arrives. The fund repays the borrowing once the call is funded, usually within a few months. For a founder, the effect is speed: a fund with a facility can wire your round now and handle the LP call afterward.

Credit facilities buy time for funds on deals that can't wait, and they give LPs fewer and larger calls on a more predictable schedule. Interest and legal fees come out of fund returns. Delaying calls shortens the measured period that LP capital is at work. Early internal rate of return (IRR) looks higher on paper even though the investments underneath perform the same. LPAs can cap the facility as a share of uncalled commitments and limit how long a single borrowing stays outstanding.

What Capital Calls Mean for Founders

Fund mechanics decide what an investor's announced fund size tells you and how fast money can move after a term sheet. Both questions come up while you're still choosing between investors.

Fund Size and Cash on Hand

A venture fund's headline size is the total its investors have committed. Its cash on hand may be far lower on any given day. Our current fund is a $750 million vehicle raised for seed and Series A investments. Committed capital like that reaches a fund in stages, one call at a time.

First-time managers feel that gap most sharply. Eunice Ajim planned to write checks in a target range of $100,000 to $150,000. More than half of the expected money did not arrive during her first capital call. She reduced those checks to $25,000 to $50,000.

Closing and Wire Timing

Legal drafting, diligence and fund mechanics all happen between signing a term sheet and funding a bank account. Priced equity rounds typically take six to 12 weeks from term sheet to close, while seed rounds on convertible instruments can close in two to four weeks. A fund with a credit line can wire almost immediately after both sides sign. Calling capital first adds the notice window on top of that.

Any CRV partner can commit the firm within 24 hours without investment committee approval. Wire timing depends on whether the fund holds cash or has to call it. When you compare investors, ask both how fast a partner can decide and how fast the fund can send the money.

Fund Diligence Questions

A few direct questions reveal more about a prospective investor than any pitch. Founders should ask about the fund's vintage and how much of it remains uncalled, since the vintage year tells you whether the fund is still deploying. Reserve policy is the second question. Funds set aside widely varying shares of capital for follow-ons. Useful answers name a percentage and say whether the investor earmarks reserves for your company or pools them across the fund.

Past follow-on behavior is worth checking too. A lead skipping your round leaves new investors wondering what the insider knows. CRV led Mercury's Series A and participated in its Series B, C and D. You learn more from an investor who names companies and rounds than from one who promises to evaluate when the time comes.

What Capital Calls Tell You About Your Investors

Capital calls are the reason committed money reaches funds in stages. Vintage and reserves shape an investor's capacity, and a credit facility can speed up a wire. We returned $275 million from Select Fund II to our limited partners in 2024 and refocused on early stage investing. Reading an investor's fund mechanics the way an LP would tells you which promises across the table are funded.

Frequently Asked Questions About Capital Calls

Is a capital call good or bad?

A capital call is routine fund plumbing in venture capital and a standard way funds convert LP commitments into investable cash. In real estate, the same term can mean that a project needs money beyond the original investment. That usage accounts for its association with warning signs. A venture fund calling capital on schedule is doing exactly what its LPA describes.

What's the difference between a capital call and a distribution?

Capital calls move money from LPs into the fund so the GP can invest it or cover expenses. Distributions run the other way and return money to LPs after the fund sells or recapitalizes its holdings. Payments usually begin later in a fund's life, often after the fund has already called most of its committed capital.

Do startups ever issue capital calls?

Startups that organize as limited liability companies (LLCs) can write capital call provisions into their operating agreements. Those provisions let the company require additional contributions from members. Founders generally incorporate venture-backed startups as C corporations (C-corps) and raise money through equity financing rounds rather than this fund-level mechanism.

Can a limited partner refuse a capital call?

An LP generally must fund a valid capital call that the GP makes under the LPA. If the LP believes the call violates the agreement, it may dispute the call, but failing to fund a valid call triggers the LPA's default remedies. Those remedies can begin with penalty interest and may culminate in forced sale or forfeiture of the LP's entire interest.
