Endowment size and reporting scope
The latest balance is labelled endowment funds, excluding pledges and is dated June 30, 2026. The return series identifies the portfolio as MIT investment portfolio / Pool A. The historical survey below retains the respondent scope reported to NACUBO. A pooled investment vehicle can include working capital, reserves or assets for associated organizations alongside endowed gifts. Each participating fund owns its own economic interest in that vehicle. The pool's market value, the institution's endowment balance and the investment manager's corporate assets describe different quantities. Official report

The survey series begins at USD 13,181.5 million in FY2016 and ends at USD 27,366.2 million in FY2025. Its USD 14,184.7 million change is measured after gifts, spending and other balance movements. NACUBO historical values FY2025 respondent table
Investment returns
| Portfolio | Period end | Horizon | Reported return |
|---|---|---|---|
| MIT investment portfolio / Pool A | June 30, 2026 | 1 year | 10.3% |
| MIT investment portfolio / Pool A | June 30, 2026 | 10 years, annualized | 11.7% |
The 1-year result is 10.3%, while the 10-year result is 11.7% annually. The trailing periods share the same end date and overlap; their percentages are not added together. A long-term annualized return describes compound growth over the full period. The year-end asset balance also reflects money entering or leaving the portfolio. Return series
Spending policy and payout
MIT says endowment support pays about half of undergraduate tuition. That share describes a specific educational cost, rather than the share of all Institute operating expenses. State law and donor terms govern the preservation and use of endowed gifts. MIT's operating budget draws on this support alongside research funding, tuition and other revenue. Spending disclosure
The policy formula controls how the operating budget receives support across market cycles. Its averaging base can differ from the latest fiscal-year-end balance. The dollar distribution records support for a stated year, while a budget-support percentage measures the institution's reliance on that support. Distribution basis
Governance and investment office
The university release explains the permanent nature of endowed gifts and their donor restrictions. The Treasurer's Report supplies the audited statements and investment notes. The office manages investments within this institutional framework. Investment governance
Federal excise tax on investment income
Public Law 119-21 changed IRC 4968 for tax years beginning after December 31, 2025. An applicable institution must have at least 3,000 tuition-paying students in the preceding tax year, with more than half located in the United States. Its student-adjusted endowment must be at least $500,000. The rate is 1.4% from $500,000 through $750,000 per student, 4% above $750,000 through $2 million, and 8% above $2 million. Enacted law, Section 70415
The tax applies to net investment income. Student-adjusted endowment uses the prior year's fair value of assets other than those used directly for exempt purposes, with statutory student-count and related-organization rules. Dividing the headline endowment by a fall enrollment number can give a different result. A rate on investment income also differs from a spending-policy percentage applied to average assets.
FY2025 size-band comparison
The FY2025 NACUBO respondent value of USD 27,366.2 million places this reporting entity in the Over $5B band. The published group contains 30 respondents. Its average annualized five-year return was 11.4%, its ten-year average was 8.9%, and its average effective spending rate was 5.0%. These are survey averages for FY2025. Respondent counts Average net returns Spending-rate table
| NCSE measure | FY2025 average |
|---|---|
| One-year net return | 11.8% |
| Five-year annualized net return | 11.4% |
| Ten-year annualized net return | 8.9% |
| Effective spending rate | 5.0% |
The size band follows the survey's FY2025 respondent balance. It does not change when a newer pool figure covers additional assets. Survey respondent values and managed-pool values retain their separate scopes. Survey allocation definitions
