Fund Structure
Investment Period
Last updated
Quick Answer
The defined window, typically 3-5 years from final close, during which a fund actively makes new investments from committed capital.
What it is
The Investment Period (also called the commitment period or deployment period) is the contractually defined timeframe during which the GP is authorized to make new investments from the fund's committed capital. Typically lasting 3-5 years from the final close, this period is when the GP sources deals, conducts due diligence, and deploys capital into new portfolio companies. After the investment period expires, the GP can generally only make follow-on investments in existing portfolio companies (from reserves) and cannot make new platform investments. The investment period is also significant for fee calculations—management fees are typically charged on committed capital during the investment period and then step down to a lower rate based on invested capital or NAV during the harvest period. The investment period can be shortened by a key person event or terminated early by an LP vote in certain circumstances.
In Practice
A fund with a 5-year investment period holds its final close in June 2024, meaning the investment period runs through June 2029. During this time, the GP deploys 65-75% of committed capital into 25-30 new portfolio companies. The remaining 25-35% is held in reserve for follow-on investments in existing winners. After June 2029, the GP cannot make new investments but can continue supporting existing portfolio companies from reserves.

Why It Matters
The investment period determines the pace at which a GP must deploy capital and the window during which founders can receive new investments from that fund. Understanding a fund's position within its investment period helps founders gauge whether a VC has capacity to invest and whether they are under pressure to deploy.
VC Beast Take
Investment periods are under pressure as deployment timelines accelerate. Many 2021-vintage funds deployed 70%+ of capital in just 18 months, leaving partners scrambling for follow-on reserves. Expect future funds to negotiate shorter investment periods (24-36 months) but with more flexible recycling provisions to adapt to market volatility.
