Savings accounts and money market deposit accounts can both hold cash and earn interest. At an FDIC-insured bank, both can qualify for deposit insurance under the same ownership-category rules. The practical differences usually come down to rate, minimum balance, access features, fees, and account terms.
What a savings account is
A savings account is a deposit account designed primarily for holding money rather than everyday transaction activity. Banks may offer different APYs, minimum balances, withdrawal methods, and monthly fees.
What a money market deposit account is
A money market deposit account, often called an MMDA, is also a bank deposit account. Some MMDAs offer check-writing or debit-card access, while others function much like savings accounts. Terms vary by institution.
Key differences to compare
| Feature | Savings account | Money market deposit account |
|---|---|---|
| FDIC insurance at insured banks | Eligible | Eligible |
| Rate | Varies | Varies |
| Minimum balance | Can be low or none | May be higher at some institutions |
| Access | Transfers, ATM or branch depending on bank | May add checks or debit access |
| Fees | Institution-specific | Institution-specific |
Which one pays more?
There is no universal answer. Some banks pay more on savings accounts; others pay more on MMDAs. Compare APY on the same date and then check balance tiers, introductory rates, fees, and conditions.
Deposit insurance
The FDIC says checking accounts, savings accounts, money market deposit accounts, and CDs are among the deposit products covered at FDIC-insured banks. Standard coverage is at least $250,000 per depositor, per insured bank, for each account ownership category, subject to applicable rules.
Transaction limits and bank rules
Federal Regulation D no longer imposes the old six-per-month withdrawal limit on savings deposits, but banks can still set their own transaction policies or fees. Read the account agreement rather than assuming every savings or money market account works the same way.
Questions to ask before opening either account
- What is the APY, and is it promotional?
- Is there a minimum balance to earn the advertised yield?
- Are there monthly maintenance fees?
- How quickly can you access the money?
- Are transfers, checks, or debit transactions limited?
- Is the institution FDIC-insured or, for a credit union, federally insured through the NCUA?
Which may fit emergency savings?
Either account can work if the money is safe, accessible enough for emergencies, and separated from routine spending. Yield matters, but access, fees, and insurance status matter too.
