Committed capital in private equity is the total dollar amount you contractually pledge to a fund at the outset, which the fund’s general partner then draws down in portions over roughly a ten-year life as deals appear. You don’t wire the full amount on day one. You promise it, and you stay on the hook for it until the fund winds down.
That promise is the whole structure. Everything else that makes private equity feel different from buying a stock or a mutual fund flows from it: the way fees are charged, the way performance is measured, the way you can and can’t get out, and the penalties if you fail to pay when the manager asks.
The Three Numbers You Track
Once you sign, three figures move together over the fund’s life.
Your commitment is the total you pledged. Your paid-in capital is the portion the fund has already called and you’ve wired in. Your unfunded commitment is the balance you still owe. Pledge $1 million, watch the fund call $400,000, and you have $400,000 paid in and $600,000 unfunded.
That remaining $600,000 does not sit in the fund. It sits with you, in your account, but it is legally spoken for. You need it accessible on short notice for the entire investment period, because a capital call can arrive at any time.
Aggregate every investor’s commitment and you get the fund’s total firepower. A fund that closes at $2 billion in commitments can plan acquisitions up to that ceiling even though only a fraction of those dollars are in the fund’s bank account at any given moment.
Who Is Allowed to Commit
Private equity funds are not open to the general public. Federal securities law lets these funds skip registering as investment companies only if their investors clear specific wealth thresholds. The most common exemption, under Section 3(c)(7) of the Investment Company Act, requires every investor to be a “qualified purchaser,” which generally means at least $5 million in investments as an individual or $25 million for most entities.1U.S. Securities and Exchange Commission (SEC.gov).

Some smaller funds use a lower bar: accredited investor status, which requires net worth above $1 million (excluding your primary residence) or income above $200,000 individually, $300,000 with a spouse.3U.S. Securities and Exchange Commission (SEC.gov). Accredited Investors In practice, the money in major buyout and growth equity funds comes overwhelmingly from institutions: pension funds, endowments, sovereign wealth funds, insurers, family offices. Individuals typically participate through fund-of-funds or feeder vehicles that pool smaller commitments.
What the Limited Partnership Agreement Locks You Into
Every commitment is governed by the Limited Partnership Agreement (LPA), the contract between the general partner (GP) and the limited partners (LPs). The LPA states your commitment amount, the fee structure, how capital gets called, and what happens if you fail to pay.
The commitment is binding. You cannot withdraw because the market turned or your cash position got tight. That rigidity is intentional: the GP has to know how much capital is actually available before negotiating billion-dollar acquisitions. If LPs could walk away mid-deal, the strategy would collapse.
The commitment is also blind. You pledge before the GP has identified specific companies to buy. You’re backing the GP’s track record, judgment, and stated strategy rather than voting on individual transactions. The LPA can include concentration limits or sector exclusions, but it will not give you deal-by-deal approval.
The Investment Period
The LPA defines an investment period, commonly the first three to five years, during which the GP actively deploys capital into new deals. Once that window closes, the GP generally cannot call capital for new acquisitions. Follow-on investments in existing portfolio companies and fund expenses are still fair game. The remaining years shift to managing and exiting the portfolio.
Fund Term
Most funds run about ten years. Your obligation to fund capital calls does not end when the investment period closes; it persists until the fund winds down. If the GP hasn’t fully exited by year ten, the LPA typically allows one or two one-year extensions, sometimes subject to LP approval.
You Pay Fees on the Full Commitment, Not Just What’s Called
The distinction between commitment and paid-in capital hits your wallet directly through the management fee. During the investment period, the GP typically charges 1.5% to 2.0% of total committed capital annually. You pay that fee on the whole pledge, not just the portion actually drawn.
If only 30% of your commitment has been called, you are still paying fees on 100% of it. The rationale is that the GP’s team is sourcing deals and running due diligence throughout the investment period regardless of how much has been deployed.
After the investment period ends, most LPAs switch the fee base from committed capital to remaining invested capital, meaning the cost basis of investments still in the portfolio. Many funds also step the fee rate down at the same point. Smaller base times smaller rate means fees drop meaningfully in the back half of the fund’s life.
How Capital Calls Actually Work
When the GP is ready to spend money, whether for an acquisition, a follow-on, or fund expenses, they issue a formal capital call notice. It states the dollar amount due from you (proportional to your commitment), the purpose, and the deadline.
Notice periods run around ten business days, though the specific window depends on the LPA. That is a tight turnaround. LPs who have committed across multiple funds and get hit with several calls in the same quarter can scramble, which is why sophisticated investors model expected calls carefully before signing anything new.
Subscription Lines of Credit
Many GPs use a subscription line of credit, a bank facility secured by the LPs’ unfunded commitments, to bridge the gap between identifying a deal and collecting LP cash. The GP closes the acquisition with the credit line, then issues the capital call, and the LP wires repay the bank, traditionally within about 90 days.4ILPA. Subscription Lines of Credit and Alignment of Interests
The operational benefit is real. The controversy is that extended use of these lines pushes back when LP capital is actually called, which shortens the measured holding period and can inflate the fund’s reported internal rate of return. The underlying investment performance is unchanged; the clock just starts later. Worth knowing when comparing IRR figures across funds.
Recallable Distributions
A wrinkle that surprises many first-time LPs: the GP can sometimes call back money already distributed to you. Recallable distributions typically cover post-distribution liabilities like litigation losses, indemnification claims, or escrow clawbacks, and can also fund late-life follow-ons.
LPAs usually put guardrails on this. A common sunset cuts off recall rights two years after the distribution or after the fund terminates, whichever comes first. LPs also negotiate caps, often around 25% to 30% of distributions received. A returned distribution is treated as a contingent liability on a past payout, not a fresh capital contribution, so it doesn’t restore unfunded commitment headroom.
What Happens if You Can’t Pay a Capital Call
Failing to fund a call is one of the most damaging mistakes an LP can make. The penalties are punitive by design, because the other investors and the fund’s strategy depend on every LP paying on time.
Most LPAs give a short cure period plus penalty interest on the late payment. If default persists past that window, the consequences escalate quickly:5Private Equity Wire. The Consequences of LP Defaults Due to Capital Calls
- Forced sale of your interest to other LPs or third parties, typically at the lesser of fair value or prior book value, minus transaction costs. Not a fair-market auction.
- Forfeiture of a significant portion, or all, of your existing interest, redistributed to the remaining partners. Some LPAs also cancel your remaining commitment and eject you from the fund entirely.
- Reallocation, where another LP or third party funds the call in your place and receives a preferred interest in that investment while you remain liable for future calls.
- Legal action, including suits for specific performance, depending on the fund’s jurisdiction.
Beyond the contractual damage, the reputational cost is severe. Fund managers talk to each other. An LP who defaults once will struggle to get into high-demand funds afterward. Defaults are rare precisely because the consequences are this harsh.
Selling Your Interest Before the Fund Winds Down
If you need out early, the secondary market is the main option. You sell your LP interest, existing investment and remaining unfunded obligation together, to another investor.
It is not like selling stock. The LPA almost always gives the GP the right to approve or block any transfer, and existing LPs may hold a right of first refusal that lets them match any outside offer. Pricing is negotiated as a discount or premium to the most recent net asset value. Strong funds in a healthy market may trade near or above NAV; in stressed conditions, discounts of 10% to 20% or more are common.
Most sellers work with a broker to structure the deal, run a data room for buyer due diligence, and navigate transfer restrictions. Listing to closing can take several months. If you are already facing a call you cannot fund, secondary sale timing will not save you.
How Performance Is Measured Against Your Commitment
Three metrics dominate LP reporting, and all of them are anchored on paid-in capital rather than committed capital.
TVPI (Total Value to Paid-In)
Total current value (estimated worth of remaining investments plus all cash already distributed) divided by total paid-in capital. TVPI of 1.5x means $1.50 of value for every dollar called. It blends realized cash with unrealized paper gains, so it gives the fullest picture but relies on the GP’s own valuations for the unrealized part.
DPI (Distributed to Paid-In)
Cumulative cash distributions divided by total paid-in capital. DPI counts only cash that has actually landed in your account. Below 1.0x means the fund hasn’t returned your principal yet. This is the cleanest read on whether the fund is actually producing returns versus sitting on paper gains. It matters most during the harvest years.
IRR (Internal Rate of Return)
A time-weighted return that captures when cash moves. A fund returning 2x in five years has a far higher IRR than one returning 2x in ten. This is where subscription credit lines create the controversy noted earlier: by delaying capital calls, the GP shortens the measured holding period and lifts IRR without changing the underlying investment result. Sophisticated LPs increasingly ask for IRR calculated both with and without credit line effects.
The J-Curve
Plot fund returns over time and you typically see a J shape. Early years show negative returns: management fees are accruing, capital is being deployed, and portfolio companies haven’t had time to appreciate. NAV dips below capital called. Then, as investments mature and exits generate cash, the curve turns up and ideally climbs well past break-even. This is normal and expected. It’s also why comparing a two-year-old fund to a seven-year-old fund tells you almost nothing.
Why Big Investors Overcommit on Purpose
Institutional LPs rarely commit exactly the cash they have available. Because calls arrive unpredictably and funds rarely draw 100% simultaneously, most sophisticated investors deliberately overcommit, pledging more total capital across multiple funds than they could fund if every fund called at once. The logic: if you earmark $100 million for private equity and commit exactly $100 million, a large share of that cash sits uninvested for years and drags down portfolio returns.
Typical overcommitment ratios for fund-of-funds managers run around 115% to 120% of available capital, with aggressive strategies reaching 140%. The math holds because calls from different funds are staggered and distributions from maturing funds recycle into newer commitments. It breaks down in a broad market dislocation, when multiple funds accelerate calls at the same time and distributions dry up. That scenario is rare, but it is exactly the one that converts an overcommitment strategy into a liquidity crisis and a potential default.
