An endowment is money or other property donated to a nonprofit organization and invested so that it can support a specific purpose over a long period, often permanently. The original gift, called the principal or corpus, is usually preserved, while the investment returns pay for the programs the donor chose. The word has a second, broader meaning: the total pool of invested assets a nonprofit holds, as when people refer to “a university’s endowment.” That pool is typically made up of hundreds or thousands of individual endowed funds, each with its own rules.

How an Endowment Works

When a donor endows a fund, the gift goes into the institution’s investment pool rather than its operating budget. The money is invested in stocks, bonds, private funds or other assets. Each year the institution withdraws a portion of the fund’s value to pay for the designated purpose, such as a scholarship, a professorship or a research program. The remainder stays invested and compounds.

The central idea is intergenerational fairness: the fund should support the purpose today without shortchanging the beneficiaries of 50 or 100 years from now. To pull that off, the long-run investment return has to cover both annual spending and inflation. If an endowment spends 5% a year and inflation runs at 3%, it needs a long-term return of roughly 8% just to keep its purchasing power flat.

Endowments are often organized within a trust, a private foundation or a public charity. Early endowments distributed only the interest and dividends they earned. Many modern endowments instead spend a fixed percentage of total value, so a year’s withdrawal can be a mix of income and realized gains on the principal. Where no formula applies, the share of income versus principal in each withdrawal shifts with market conditions.

The Three Governing Policies

Every endowment fund operates under three sets of rules, set out in the gift agreement and in the institution’s own policies.

Investment policy. This defines which assets the manager may buy and how much risk the fund may take while pursuing its target return. Because the money is meant to last, many endowments write long-term goals, such as a specific rate of return or yield, into their legal structure, and the asset allocation is designed to meet them over decades rather than quarters. Large universities pool hundreds or thousands of smaller endowed funds into a single investment vehicle, and each fund owns units of the pool, much like shares of a mutual fund priced at net asset value.

Withdrawal policy. Also called the spending policy, this sets how much the institution may take out each period. It weighs the organization’s needs against the size of the fund, and it usually includes an annual limit. A fund might, for example, cap withdrawals at 5% of its total value. Because most university endowments are intended to last forever, they almost always operate with a spending limit.

Usage policy. This defines what the money can pay for. Common uses include supporting a specific department, funding merit scholarships, fellowships or other student aid, and paying for endowed professorships. An endowed chair is funded by the endowment’s income, which frees operating money for other hiring; these chairs carry prestige and usually go to senior faculty. Endowments can also be tied to a single discipline, program or facility. Smith College, for instance, has an endowment dedicated to its botanic garden, and Harvard University holds more than 14,600 separate endowment funds.

Types of Endowments

Endowments are classified by how much freedom the institution has over the principal:

• Restricted (true or permanent) endowment: The principal is held in perpetuity. Only the investment earnings can be spent, and only on the purpose the donor specified. This is the classic form most people mean by “endowment.”
• Term endowment: The principal must be preserved for a set period or until a specified event occurs. After that, the institution may spend it.
• Quasi-endowment (board-designated fund): The institution creates it from its own unrestricted money, often by internal transfer, and invests it for the long term. The principal is normally kept intact, but because the board imposed the restriction rather than a donor, the board can generally reverse it.
• Unrestricted endowment: The institution can spend, save, invest or distribute the assets at its discretion.

Not every endowment is restricted. A true endowment is defined by the donor’s restriction on spending the principal, but board-designated and unrestricted funds carry limits the institution sets itself, which is why financial statements separate donor-restricted from board-designated money.

Donor restrictions are hard to undo. Spending the corpus of a restricted endowment to pay debts or operating expenses is called invading the endowment (endowment fund invasion), and it may require court approval. If a donor’s purpose becomes impossible or impractical, for example because the institution is near bankruptcy or the original program no longer exists, a court can apply the cy pres doctrine. Under cy pres, the court redirects the gift to a use that comes as close as possible to the donor’s original intent.

Worked Example: A Hypothetical Endowed Scholarship

The figures below are illustrative assumptions, not any institution’s actual terms.

A donor gives $1,000,000 to a college to fund need-based scholarships in perpetuity. The gift agreement makes it a restricted endowment. The college’s spending policy allows 5% of the fund’s value each year, and its investment pool targets a long-term return of 8%.

Year 1:

• Starting value: $1,000,000
• Assumed investment return (8%): +$80,000
• Spending distribution (5% of starting value): −$50,000
• Ending value: $1,030,000

The $50,000 pays for scholarships. The extra $30,000 stays in the fund, roughly matching an assumed 3% inflation rate, so the fund’s real purchasing power holds steady and next year’s distribution rises to about $51,500.

A bad year: Suppose the pool loses 10% in year 2. The fund falls from $1,030,000 to $927,000 before spending. A strict 5% rule applied to that lower figure would cut scholarships to about $46,350. To avoid such swings, many institutions apply the spending rate to an average of several years’ values, for instance the average of the last 12 quarter-end balances. Smoothing keeps payouts steadier, but it means the fund spends slightly more of its principal after a downturn.

This is the trade-off at the heart of every withdrawal policy: a higher payout helps today’s students, while a lower one protects future students. If returns fall short of spending plus inflation for long enough, the endowment shrinks in real terms even if its dollar value looks stable.

Rules and Requirements for Endowments in the U.S.

State law. Most U.S. states have adopted a version of the Uniform Prudent Management of Institutional Funds Act (UPMIFA), which requires institutions to invest and spend endowment funds prudently, considering factors such as the fund’s duration, economic conditions, inflation and the donor’s intent.

Private foundations. Under federal tax law, private foundations must pay out at least 5% of their investment assets each year for charitable purposes or risk penalties and their tax-exempt status. Private operating foundations, which run their own charitable programs, must generally spend 85% or more of their investment income on those activities. Community foundations have no mandatory payout requirement.

University excise tax. The Tax Cuts and Jobs Act of 2017 introduced an excise tax on the net investment income of large endowments at private colleges and universities. Legislation enacted on July 4, 2025 (Public Law 119-21) changed it to a tiered tax of 1.4% to 8% of net investment income, depending on endowment assets per student, with the tax starting at institutions holding at least $500,000 per student and the top rate tied to $2,000,000 per student. An institution falls under the tax only if it has at least 3,000 tuition-paying students, more than half of whom are located in the United States. Public universities are not covered.

Where Endowments Get Their Money

An institution’s total endowment is the sum of many individual gifts, each with its own terms. A donor might, for example, fund research only in a graduate anthropology department, and that money cannot be shifted to athletics or building maintenance. Donors tend to be high-net-worth individuals, families or groups who want to specify exactly how their money is used and keep funding a cause after they are gone. Gifts may arrive as cash, securities, real estate or bequests, and for the largest funds, new donations and compounding together drive growth.

Who Manages Endowments

An institution may employ an internal investment office or hire an outside firm, such as an outsourced chief investment officer, to run the money. In either case, the board of trustees sets the rules: it approves the investment policy, the spending rate and the governance structure, and it oversees the managers. Large university endowments often allocate heavily to alternative assets such as hedge funds, private equity and venture capital, an approach associated with the “endowment model” popularized at Yale.

Who Can Receive an Endowment

Any nonprofit educational, charitable, religious or scientific institution can receive an endowment. Typical recipients include colleges and universities, private secondary schools, museums, libraries, religious organizations, hospitals and retirement homes. Individuals do not hold endowments in this sense; a student might benefit from an endowed scholarship, but the endowment belongs to the institution.

Endowments and Higher Education

Endowments are so embedded in U.S. academia that a school’s endowment size is often treated as a gauge of its financial strength. Endowment income lets colleges fund operations from sources other than tuition and provides reserves for difficult years. Older institutions, including the Ivy League schools, have built especially large funds thanks to generations of donations from wealthy graduates and long-running investment programs.

Harvard’s Endowment as an Illustration

Harvard runs the largest university endowment in the U.S., and its reported results show how these funds behave. When the pandemic hit, officials expected the endowment to shrink in fiscal 2020; instead it returned 7.3% and grew slightly. In fiscal 2021, helped by a rising stock market, it returned 33.6% and rose by $11.3 billion to $53.2 billion. Returns then flattened: −1.8% in fiscal 2022 and 2.9% in fiscal 2023.

For fiscal 2023, Harvard reported an asset allocation of roughly 39% private equity, 31% hedge funds, 11% public equity, 6% bonds, 5% real estate and 7% other assets and cash. Its payout that year totaled $2.2 billion.

Limitations and Criticism of Endowments

Restricted money is not flexible money. A large endowment does not mean an institution can spend freely. Because most of the assets are donor-restricted, a university with tens of billions in its endowment cannot simply use it to cut tuition for everyone or cover general operating costs. A fund restricted to an obscure program can sit idle while other needs go unmet, and changing that requires the donor’s consent or a court process.

Accusations of hoarding. Critics have likened the growth of elite university endowments to hoarding wealth that could be spent on students and research now. The criticism sharpened after the Great Recession, when many endowments that had been described as rainy-day funds cut their payouts instead of drawing on them. A 2014 study in the American Economic Review examined that behavior and found that institutions tended to put the health of the endowment ahead of the institution as a whole.

Market risk. An endowment’s spending depends on investment returns. A deep market decline reduces the fund’s value and, under a percentage-based rule, the following year’s payout. Heavy allocations to private equity, hedge funds and other illiquid assets can make it harder to raise cash quickly and can make reported values lag market reality.

Controversial investments. Students and activists often scrutinize where endowments are invested. In 1977, Hampshire College divested from companies doing business in apartheid South Africa, and many U.S. institutions later followed. Wealthy universities have also faced public pressure over federal aid: Harvard, Princeton and Stanford declined funds they were set to receive from the $14 billion higher education package in the CARES Act, and Harvard turned down pandemic relief three times, including $25.5 million from the American Rescue Plan.

Endowment vs. Related Terms

Several terms share the word or overlap in meaning, and they work differently.

Endowment vs. foundation. A foundation is a legal entity, usually funded by an individual, family or company, that makes grants to other organizations; an endowment is a pool of invested assets held for a purpose. A foundation may have an endowment (its investment assets) and faces the federal 5% minimum payout, while a university endowment is held by the university itself and is not subject to that rule.

Endowment vs. endowment policy. An endowment policy is a life insurance product, common in the U.K., India and other markets. It pays a lump sum either when the policy matures after a fixed term or when the insured person dies, whichever comes first. It combines insurance with saving, belongs to the individual policyholder and has nothing to do with nonprofit endowment funds.

Endowment vs. the endowment effect. In behavioral finance, the endowment effect is the tendency to value something more highly simply because you own it, for example demanding more to sell a stock than you would pay to buy it. It is a cognitive bias, not a fund.

The Bottom Line

Endowments matter to donors deciding how their gifts will be used, to trustees setting spending and investment rules, and to students and staff who rely on endowed scholarships and positions. A large endowment does not mean an institution can spend freely, since most assets are donor-restricted and payouts depend on investment returns. A fund keeps its value only if long-run returns cover both annual spending and inflation.
