How Mutual Funds Work

4 min

Mutual funds pool money from many investors to buy a diversified portfolio of stocks, bonds, or other securities. They're one of the most popular investment vehicles for retirement accounts.

The Basics

When you buy shares of a mutual fund, your money is combined with thousands of other investors. A professional fund manager uses this pool to buy a diversified mix of investments. You own a proportional share of everything in the fund.

Net Asset Value (NAV)

Mutual funds are priced once per day at market close. The NAV is calculated by dividing total assets minus liabilities by the number of shares. Unlike stocks, you can't trade mutual funds throughout the day. All orders execute at the closing NAV.

NAV = (Total Fund Assets - Liabilities) / Total Shares Outstanding
Example:
A fund with $100 million in assets, $1 million in liabilities, and 5 million shares has NAV of $19.80

Minimum Investments

Many mutual funds require minimum initial investments, often $1,000-$3,000. Some have lower minimums for retirement accounts. This is different from ETFs, which you can buy one share at a time.
