When deciding where to keep your short-term cash—whether for emergencies, upcoming expenses, or idle funds—knowing the differences between money market funds (MMFs) and savings accounts can help you make the best choice.
What is a Money Market Fund?
A money market fund pools investors’ money to buy highly liquid, low-risk, short-term debt securities such as U.S. Treasury bills, certificates of deposit (CDs), and commercial paper. Managed by investment professionals, MMFs aim to offer stability by maintaining a net asset value (NAV) of $1.00 per share and typically deliver yields higher than traditional savings accounts. However, they are investment products and—not being bank deposits—do not carry FDIC insurance, involving some risk including the rare event known as “breaking the buck,” where the NAV falls below $1.
What is a Savings Account?
Savings accounts are deposit accounts offered by banks and credit unions that allow you to safely store money while earning interest. They offer easy liquidity and principal protection through federal insurance: either FDIC (Federal Deposit Insurance Corporation) for banks or NCUA (National Credit Union Administration) for credit unions, insuring up to $250,000 per depositor, per institution. These accounts usually have low or no minimum balance requirements and minimal fees, making them popular for emergency funds and short-term savings goals.
Comparing Features
| Feature | Money Market Fund (MMF) | Savings Account |
|---|---|---|
| Type | Investment (mutual fund) | Deposit account (bank/credit union) |
| Insurance | Not FDIC-insured; SIPC protection applies to brokerage accounts only | FDIC or NCUA insured up to $250,000 per depositor |
| Liquidity | High, with redemptions typically processed within a business day | High, immediate access with possible transaction limits |
| Risk | Low but not zero; potential for NAV fluctuation | |
| Very low; principal protected by federal insurance | ||
| Returns | Variable interest, often higher than savings accounts | |
| Generally lower, but steadily growing with high-yield accounts | ||
| Accessibility | Through brokerage or mutual fund platforms | |
| Through bank or credit union branches and online platforms | ||
| Minimums | Often higher (e.g., $1,000+) | |
| Usually low or none | ||
| Fees | Management fees/expense ratios reduce returns | |
| Usually minimal or none |
Safety and Insurance Explained
The principal safety is the clearest dividing line. Savings accounts benefit from FDIC or NCUA insurance, safeguarding deposits up to $250,000 per depositor per institution, even if the financial institution fails. This insurance ensures your money’s safety and makes savings accounts ideal for emergency funds.
Money market funds, by contrast, are investment pools regulated by the SEC but not federally insured. While they invest in highly stable instruments and are designed to maintain a $1 NAV, the value can fluctuate slightly and rarely may dip below $1, causing losses. In brokerage accounts, SIPC protection covers losses from brokerage failure (up to $500,000), but SIPC does not protect against market losses.
When to Choose a Money Market Fund
Money market funds suit investors seeking potentially higher yields on liquid cash balances, especially if you have larger sums and are comfortable with minimal risk. They are useful when parking funds temporarily while waiting for investment opportunities or other uses. However, MMFs should follow having an emergency fund held securely in an FDIC-insured account.
When to Choose a Savings Account
Savings accounts are preferable if your priority is safety, easy access, or holding your emergency fund. They fit short- to medium-term goals where principal protection and predictable, if modest, interest income are more important than maximizing yield.
Common Misconceptions
- MMFs are not FDIC-insured; money market deposit accounts offered by banks are different and carry FDIC insurance.
- MMFs carry minimal but real risk of loss; savings accounts protect principal fully.
- Fees in MMFs can reduce returns;
- Savings account interest may lag behind inflation, reducing purchasing power over time.
Tips for Choosing
- Define your purpose for the funds.
- Assess your risk tolerance.
- Consider how soon you’ll need the money.
- Compare current interest rates and fees.
- Keep your emergency fund in an FDIC-insured savings account.
- Consider using both options for different parts of your cash.
For example, many keep an emergency savings fund securely in a savings account while parking extra cash in a money market fund for better yield and liquidity.
