A money market account (MMA) is a deposit account at a bank or credit union that combines features of savings and checking. Like a savings account, it pays interest — historically slightly higher than savings, though the gap has narrowed against high-yield savings accounts. Like a checking account, it typically allows a limited number of monthly transactions, including debit-card purchases and check-writing. MMAs are FDIC-insured (or NCUA-insured at credit unions) up to the standard $250,000 per depositor.
How MMAs Differ From Savings and Checking
The major distinctions:
From a savings account: MMAs offer check-writing and debit-card access; pure savings accounts typically don't. Some MMAs require a higher minimum balance ($1,000 to $10,000) than savings, especially to qualify for the published interest rate.
From a checking account: MMAs limit transactions per month (typically 6 outgoing transactions, though Regulation D's strict cap was paused in 2020 and many banks dropped it). Checking accounts have no transaction caps. MMAs generally pay higher interest than checking.
MMAs sit between the two products in flexibility and compensation: a bit more liquid than savings, a bit less liquid than checking, with rates that have historically been competitive with savings.
When MMAs Are the Right Tool
MMAs work well for the cash you want to keep accessible but not actively spending — large emergency funds, short-term goal money, or down-payment savings. The check-writing and debit-card features make rare large withdrawals easy without needing to first transfer to checking.
For a household with a $50,000 emergency fund: an MMA might be the right home if you occasionally need to write a large check (medical expense, large repair) and don't want to ladder through a transfer to checking. For a $5,000 emergency fund, a HYSA is usually simpler and pays similar or higher rates.
Where Brokerage Money Market Funds Differ
A money market mutual fund (offered by brokerages like Vanguard, Fidelity, Schwab, Public.com) is structurally different from a money market account. Money market funds are mutual funds that invest in short-term debt (Treasuries, commercial paper, repurchase agreements). They are not FDIC-insured. The yield is typically slightly higher than bank MMAs, and the liquidity is good — usually next-day settlement.
The distinction matters for safety: bank MMAs are FDIC-protected against bank failure; money market funds rely on the underlying investments and the fund's discipline. Money market funds rarely "break the buck" (drop below $1.00 NAV) but have done so in the past, most prominently in 2008.
For most retail savers, bank MMAs are simpler and equally yielding once you compare apples to apples. For larger balances, brokerage money market funds can be marginally more efficient.

What MMA Rates Look Like
As of 2026, top MMAs at competitive online banks pay 4.0% to 4.8% APY — closely matching top high-yield savings rates. Large incumbent banks pay much less (often under 1%). Promotional MMAs may pay above 5% briefly to attract new deposits but typically revert.
Minimum-balance requirements are common at MMAs. A 4.5% APY may apply only to balances above $10,000; below that, the rate may drop to 0.10%. Read the rate-tier disclosures carefully.
MMA vs. HYSA vs. CD: A Quick Decision Tree
For pure savings with no withdrawal needs and no minimum-balance gymnastics: HYSA. The simplest, often the highest yield.
For savings where you might occasionally write a large check or use a debit card: MMA, ideally with no minimum-balance requirement to qualify for the rate.
For money you definitely won't need for a known period (12, 24, 60 months): CD. Higher rate in exchange for the liquidity sacrifice.
For money you may want to invest at higher long-term return: brokerage account, retirement account, or money market fund (as a holding place between investments).

Frequently Asked Questions
Is a money market account safe?
MMAs at FDIC-insured banks are protected up to $250,000 per depositor, per bank, per ownership category — the same as savings accounts. NCUA insures credit-union MMAs equivalently.
Is a money market account the same as a money market fund?
No. MMA is a bank deposit account (FDIC-insured). Money market fund is a brokerage mutual fund (not FDIC-insured). Yields are similar but the legal protections differ.
Can I write checks from a money market account?
Yes, most MMAs allow limited check-writing — typically 6 transactions per month including check, debit-card, and ACH transactions, though many banks have relaxed the cap.
Are MMA rates better than HYSA rates?
Historically MMAs paid more than savings; in 2026, top HYSAs and top MMAs are roughly even. Compare specific institutions rather than relying on category-level averages.
