## What Is a Fund?

A fund is a pool of money that is allocated for a specific purpose. A fund can be established for many different purposes: a city government may set aside money to build a new civic center, a college may set aside money to award a scholarship, or an insurance company may set aside money to pay its customers’ claims.

### Key Takeaways

*   A fund is a pool of money set aside for a specific purpose.

## How Funds Work

Individuals, businesses, and governments all use funds to set aside money. Individuals might establish an emergency fund—also called a rainy-day fund—to pay for unforeseen expenses or start a [trust fund](https://www.investopedia.com/terms/t/trust-fund.asp) to set aside money for a specific person.

Individual and institutional investors can also place money in different types of funds with the goal of earning money. Examples include mutual funds, which gather money from numerous investors and invest it in a diversified portfolio of assets, and hedge funds, which invest the assets of [high-net-worth individuals (HNWIs)](https://www.investopedia.com/terms/h/hnwi.asp) and institutions in a way that is designed to earn above-market returns. Governments use funds, such as special revenue funds, to pay for specific public expenses.

## Types of Funds

The following are examples of funds commonly used for personal ventures:

*   **Emergency funds** are personal savings vehicles created by individuals used to cover periods of financial hardship, such as job loss, prolonged illness, or a major expense. The rule of thumb is to create an emergency fund that contains at least three months' worth of net income.
*   **College funds** are usually tax-advantaged savings plans set up by families to allocate funds for their children’s college expenses.
*   **Trust funds** are legal arrangements set up by a grantor who appoints a trustee to administer valuable assets for the benefit of one or more listed beneficiaries for a period of time, after which all or a portion of the funds are released to the beneficiary or beneficiaries.
*   **Retirement funds** are savings vehicles used by individuals saving for retirement. Retirees receive monthly income or pensions from retirement funds.

In the realm of investments, some types of funds include:

*   [**Mutual funds**](https://www.investopedia.com/terms/m/mutualfund.asp) are investment funds managed by professional managers who allocate the funds received from individual investors into stocks, bonds, and/or other assets.
*   [**Money-market funds**](https://www.investopedia.com/terms/m/money-marketfund.asp) are highly liquid mutual funds purchased to earn interest for investors through short-term interest-bearing securities, such as [Treasury bills](https://www.investopedia.com/terms/t/treasurybill.asp) and commercial paper.
*   [**Exchange-traded funds (ETFs)**](https://www.investopedia.com/terms/e/etf.asp) are similar to mutual funds but are traded on public exchanges (similar to stocks).
*   **Hedge funds** are investment vehicles for high-net-worth individuals or institutions designed to increase the return on investors’ pooled funds by incorporating high-risk strategies such as short selling, derivatives, and leverage.
*   **Government bond funds** are for investors looking to put their money away in low-risk investments through Treasury securities, such as [Treasury bonds](https://www.investopedia.com/terms/t/treasurybond.asp), or agency-issued debt, such as securities issued by Fannie Mae. Both alternatives are backed by the U.S. government.

The government also creates funds that are allocated for various reasons. Some government funds include:

*   **Debt-service funds** are allocated to repay the government’s debt.
*   **Capital projects funds** are resources used to finance the capital projects of a country, such as purchasing, building, or renovating equipment, structures, and other [capital assets](https://www.investopedia.com/terms/c/capitalasset.asp).
*   **Permanent funds** are investments and other resources that the government is not allowed to cash out or spend; however, the government normally has the right to spend any revenue these investments generate on appropriate functions of government.

## How Do You Start a Fund?

How you start a fund will depend on what type of fund you want to establish. If it is an emergency fund, a simple way to start one is to set aside a small portion of money every week or month in a separate bank account. Starting an investment fund is more complicated. You would first need to have a professional background, raise money to start the basics of a fund, such as incorporating it and any trading equipment, then you would need to decide on an investment strategy and attract investors willing to invest capital into your fund.

## What Is the Purpose of a Fund?

The purpose of a fund is to set aside a certain amount of money for a specific need. An emergency fund is used by individuals and families to use in times of emergency. Investment funds are used by investors to pool capital and generate a return. College funds are usually set up by parents to contribute money to a child's future college education.

## What Is an Example of a Fund?

An example of a fund is a mutual fund. Mutual funds accept money from investors and use that money to invest in a variety of assets. Mutual funds have managers that manage the fund for a fee, which they charge to investors. Investors allocate money to mutual funds in hopes of increasing their wealth.

## The Bottom Line

A fund is a pool of money that has been created for a specific reason. There are different types of funds that exist for different purposes. An emergency fund is created by individuals and families for emergency expenses, such as medical bills or to pay for rent and food if a wage earner loses a job.

An investment fund is an entity created to pool the money of various investors with the goal of investing that money into various assets in order to generate a return on the invested capital. Individuals, governments, families, and investors all use funds for very different purposes, but the essential goal remains the same: to set aside a certain amount of money for a specific need.
