The Best Money Market Funds

Editorial Policy Disclosure

A money market fund is one of the safest investments you can make. You won’t see big long-term growth like you might with a high-performing stock (the average money market fund increases in value by 1% to 3% a year), but your investment is likely to keep pace with inflation without the risks associated with stock trading. Most money market funds invest in cash or debt securities like certificates of deposit (CDs), government-backed U.S. Treasury bonds, or high-quality corporate debt. Overall, they’re a good place to park your cash since they pay a bit more than a standard savings or money market account while still being less volatile than the stock market.

What is a Money Market Fund?

A money market fund is a type of mutual fund that invests in short-term debt or cash securities to provide you with a modest but relatively predictable level of growth. A money market fund significantly less risky than stock trading, but slightly riskier than a savings account, since a savings account will never decrease in value. However, since a “healthy” inflation rate is around 2% per year, there’s a chance your savings account won’t keep up with inflation (unless you find one with a really high interest rate). Money market funds may earn you a bit more than a bank savings account, but will not dramatically grow in value like some stocks.

Money Market Funds vs. Money Market Accounts

It’s easy to confuse the two products, but there are major differences. As we noted above, a money market fund is an investment product closer to a mutual fund than a bank account. Since your cash is invested, money market funds are not FDIC-insured.

Money market funds usually perform better and pay a bit more interest (1% to 4%) than a money market account (around 1%). Money market fund shares are liquid and can be cashed out by buying and selling without any restrictions or penalties. Although they’re an investment vehicle, many money market funds come with check-writing privileges.

On the other hand, a money market account is a bank account similar to a savings account. Money market accounts are FDIC-insured and earn interest over time. They may be more restrictive than a money market fund, but are far more flexible than a CD. Some money market accounts come with check-writing and debit card privileges, but like savings accounts, they’re still limited to six withdrawals or transactions per month under federal law.

Money Market Funds vs. Mutual Funds

Money market funds and mutual funds are both a type of investment managed by a professional. The main difference between the two comes down to why you’re investing your cash, for how long, and with what tolerance for risk. Do you have a short-term goal or are you looking for long-term wealth? A money market fund is best for short-term goals like having an emergency savings fund that’s slowly and safely growing. A mutual fund is better when you don’t need the money for several years and want to see your investment grow; with a longer investment period, some mutual funds have a much higher threshold for risk and volatility than a money market fund.

Money market funds are more cost-effective because they don’t charge extra fees when you buy in or cash out. Mutual funds come with several fees, including an annual expense ratio fee, charged as a percent of the fund to cover administrative and management costs.

Money Market Funds vs. Index Funds

An index fund is a mutual fund with the goal of duplicating the performance of one of the stock market indexes like the S&P 500 or Nasdaq. Mutual funds, on the other hand, are custom portfolios that a manager believes will the market’s “index” performances. Index funds typically have lower fees than mutual funds and are designed for a shorter investment period than a mutual fund.

Although index funds may be lower risk and better for short-term investments than a mutual fund, a money market fund is still the best option if you don’t want to risk your investment and need access to your principal in the near future.
