A money market account (MMA) is a bank or credit union deposit account that pays more interest than a standard savings account and may include limited check-writing and debit card privileges. In 2026, the best money market accounts earn 4.00%–4.50% APY with no minimum balance — making them one of the best options for cash you want to keep safe but accessible.
Money Market Account Definition
A money market account is a federally insured savings deposit account that:
- Pays a variable interest rate (typically higher than a standard savings account)
- Is backed by FDIC insurance (at banks) or NCUA insurance (at credit unions) up to $250,000
- May include check-writing privileges and sometimes a debit card
- Has no fixed term — unlike a CD, you can withdraw anytime
The name comes from the “money markets” — the short-term lending markets where banks invest your deposits. Banks historically justified higher rates for MMAs by investing in these markets, though in practice today the rate difference between a top MMA and a top HYSA is small.

| Withdrawal limits | Varies by bank | Varies by bank | Unlimited | Penalty before maturity |
| Minimum balance | $0–$25,000 | $0–$500 | $0–$1,500 | $500–$1,000 |

How Interest Works on a Money Market Account
Interest on MMAs is typically:
- Compounded daily and credited to your account monthly
- Variable — the rate adjusts when the Federal Reserve changes the federal funds rate
- Expressed as APY (annual percentage yield), which accounts for compounding
Worked example: You deposit $20,000 into an MMA earning 4.20% APY. After one year:
- Interest earned: approximately $840
- Ending balance: approximately $20,840
If the Fed cuts rates and the APY drops to 3.80% midyear, your actual return will fall between those two figures.
Who Offers Money Market Accounts?
- Traditional banks — Chase, Bank of America, Wells Fargo (typically low rates, high minimums)
- Online banks — Ally, Marcus, Discover, LendingClub (best rates, low minimums)
- Credit unions — rates and minimums vary; membership required
- Savings institutions / thrifts — similar to banks
Do NOT confuse bank money market accounts with:
- Money market funds (investment products at brokerages — not FDIC insured)
- Money market ETFs (exchange-traded fund equivalents — not FDIC insured)
Is a Money Market Account Right for You?
Yes if you:
- Want a safe, FDIC-insured account that earns more than 0.50% APY
- Occasionally need check-writing access without a full checking account
- Are building an emergency fund or saving for a short-term goal
- Have a balance large enough to meet minimum requirements (if any)
No if you:
- Need to make frequent daily transactions (use a checking account instead)
- Want a guaranteed fixed rate for a specific period (use a CD instead)
- Are investing for long-term growth (use investment accounts instead)
