In practice
Dry powder is usually measured at the fund level from commitments less drawn capital, and then summed across funds. Some counts also net out amounts reserved for fees, follow-on investments or expenses, so totals differ by source. It is often confused with cash held by a fund, which is only the part already called from investors.
An example
Round numbers, not a real fundSay a fund has $2 billion committed and has invested $1.2 billion of it so far. The other $800 million is still uninvested: that is the fund’s dry powder.
Why it matters
A large pile of it means competition for deals, and pressure on managers to spend before their investment periods end.
A definition, not advice; where usage varies the entry says so. Something wrong? Tell the desk.
