What is an 'Income Fund'

An income fund is a type of mutual fund or exchange-traded fund (ETF) that emphasizes current income, either on a monthly or quarterly basis, as opposed to capital appreciation. Such funds usually hold a variety of government, municipal and corporate debt obligations, preferred stock, money market instruments, and dividend-paying stocks.


Share prices of income funds are not fixed; they tend to fall when interest rates are rising and to increase when interest rates are falling. Generally, the bonds included in the portfolios of these funds are investment-grade. The other securities are of sufficient credit quality to assure a preservation of capital.

There are two popular types of high-risk funds that also focus mainly on income: high-yield bond funds that invest primarily in corporate junk bonds and bank loan funds that invest in floating-rate loans issued by banks or other financial institutions.

Income funds come in several varieties. The primary differentiation involves the types of securities they invest in to generate income.

Money Market Funds

Money market funds generally invest in certificates of deposit (CDs), commercial paper and short-term Treasury bills. These funds are designed to be very safe investments aiming to maintain a low share price at all times, but they also tend to offer relatively low yields. While these funds don't carry the Federal Deposit Insurance Corporation (FDIC) insurance that bank products do, money market funds have traditionally provided a high degree of safety.

Bond Funds

Bond funds typically invest in corporate and government bonds. Government bond funds carry virtually no default risk and, therefore, can act as a safe haven for investors in times of uncertainty, but normally offer lower yields than comparable corporate bond funds. Corporate bonds carry the additional risk that the issuer may not be able to make principal or interest payments. As a result, they tend to pay higher interest rates to account for the additional risk. Corporate bond funds can be split into investment-grade bond funds and below investment-grade, or junk, bond funds.

Equity Income Funds

Many companies pay dividends on their stocks. Funds invested primarily in stocks that pay regular dividends are known as equity income funds. These types of funds are especially popular among retirement age investors that look to live off of the predictable monthly income generated from their portfolios. Historically, dividends have provided a significant percentage of a stock's total long-term return.

Other Income Funds

Other income-producing funds include those focused on real estate investment trusts (REITs), master limited partnerships (MLPs) and preferred stocks.
