What is committed capital?
Committed capital is the sum of all the binding pledges investors make to a fund at closing. When an LP signs a subscription agreement, it commits a fixed amount — say $50 million — that the GP can draw against over the fund's investment period. The aggregate of every LP's commitment, plus the GP's own, is the fund's committed capital, and it is what people mean by "fund size."
Crucially, a commitment is a promise, not a payment. The money is not transferred at closing; it is contributed in pieces as the GP issues capital calls to fund investments and expenses. An LP's commitment therefore splits at any moment into the portion already drawn (contributed capital) and the portion still owed (uncalled commitment, or dry powder).
This distinction is the foundation of the entire private-fund model. It lets a GP secure a large pool of capital it can deploy opportunistically, while letting LPs keep their money productive until it is genuinely needed.
Why committed capital is the master number
Committed capital anchors most of a fund's mechanics, which is why it appears everywhere in fund documents.
- Fee base. Management fees are conventionally charged as a percentage of committed capital during the investment period — so an LP pays fees on its full commitment even before all of it is drawn.
- Pro-rata allocation. Each LP's share of every capital call, distribution, and gain is set by its commitment relative to total commitments.
- Investment capacity. The size of deals a fund can pursue and the diversification it can achieve are bounded by total commitments.
- Performance framing. Metrics like the ratio of called-to-committed capital signal how far along a fund is in deploying its pool.
Because fees often run on committed rather than invested capital, an LP effectively pays for capital it has not yet put to work. This is one reason the fee base eventually steps down — typically shifting to invested capital — once a fund exits its investment period.
Committed vs. called vs. invested capital
These three terms are easy to confuse but describe different things. Committed capital is what an LP has promised. Called (or contributed) capital is what the GP has actually drawn down so far. Invested capital is the portion of called capital that has gone into actual portfolio investments, as opposed to fees and expenses.
The gaps between them matter. Committed minus called is the fund's dry powder. Called minus invested reflects the drag of fees and costs. Tracking all three over time is how an LP understands not just how big its commitment is, but how much of it is at work, how much is still owed, and how efficiently the fund is converting promises into investments.
