Summary
Princeton University's endowment generated an 11% return on investments for the fiscal year ended June 30, 2025, bringing total assets to $36.4 billion. This represents the endowment's strongest performance in four years and reflects broader market strength during the period. The absolute gain added $2.3 billion in value compared to the prior year's $34.1 billion, demonstrating robust capital appreciation in a rebounding investment environment.
The 11% return aligns closely with peer institutional performance. Yale's endowment posted identical 11% gains while reaching $44.1 billion in assets, indicating comparable market conditions benefited large university investment portfolios across the sector. Both institutions benefited from favorable equity and alternative investment performance during fiscal 2025.
From a longer-term perspective, Princeton's endowment has sustained solid average returns. The 20-year average annual return ranges from 9.5% to 11.0%, depending on the measurement period used, reflecting disciplined asset allocation and investment management practices. The 10-year average return of 12.2% indicates that recent performance, while strong, remains slightly below the trailing-decade average—a typical pattern as markets normalize following exceptional periods.
The endowment's substantial asset base continues to serve as a critical financial pillar for Princeton University, funding operational expenses, faculty compensation, student aid, and capital projects. The 11% fiscal 2025 return positions the institution to maintain spending commitments and weather future market volatility, though the endowment operates within the context of ongoing policy and regulatory considerations affecting large university investment funds.
