Walk into most banks and you’ll be offered a savings account, a money market account, and maybe a CD. The names make them sound very different. In reality, a high-yield savings account and a money market account are close cousins, and for many people the choice comes down to one or two small features.
The quick version
- High-yield savings account (HYSA): a savings account, usually from an online bank, that pays well above the national average. Simple, often no minimum, no checks or debit card.
- Money market account (MMA): a deposit account that sometimes comes with checks or a debit card. Rates can be competitive, but some require a higher balance to earn the advertised rate.
Both are deposit accounts. If the bank is an FDIC member, both are insured up to $250,000 per depositor, per bank, per ownership category. (Credit unions offer equivalents insured by the NCUA.) Our explainer on how FDIC insurance works goes into those categories.
Don’t confuse a money market account with a money market fund
This trips a lot of people up. A money market fund is an investment product sold by brokerages. It’s generally low-risk, but it is not FDIC-insured. A money market account is a bank deposit and is insured. The SEC’s investor education site has a plain-English overview of investment products, including money market funds, if you want the details.
Where they differ
Access to your money
This is the biggest practical difference. Many money market accounts let you write a few checks or use a debit card. A typical HYSA only lets you transfer money to a linked checking account, which takes a day or two.
The federal rule that once capped “convenient” withdrawals at six per month was dropped in 2020, but plenty of banks still keep a limit of their own. Read the account terms before you assume unlimited access.
Minimum balances
Online HYSAs often have no minimum at all. Money market accounts are more likely to require a minimum deposit to open, a minimum balance to avoid fees, or a tiered rate that only pays the headline APY above a certain balance.
Interest rates
There’s no rule that one pays more than the other. Online banks tend to lead on HYSA rates because they don’t run branches. Rates on both are variable and move with the broader rate environment. Compare the APY, not the interest rate — we explain why in APY vs. APR.
Which one should you choose?
A high-yield savings account tends to fit better if:
- You’re building an emergency fund and you want a little friction so you don’t spend it.
- You’re starting with a small balance.
- You’re happy banking online.
A money market account tends to fit better if:
- You keep a larger balance and want to pay a few big bills (like a property tax bill or contractor) straight from it.
- You prefer your savings at the same bank as your checking.
- The rate at your target balance is competitive with online HYSAs.
A few things to check before opening either
- Is it FDIC or NCUA insured? You can look up a bank with the FDIC’s BankFind tool.
- Is the rate promotional? Some teaser rates drop after a few months.
- Monthly fees and how to avoid them.
- Transfer speed and limits to your checking account.

What about money you won’t touch for a year or more?
If you know you won’t need part of your savings for a while, a certificate of deposit may pay a fixed rate that beats both. Many people combine accounts: an HYSA for instant-access cash and a CD ladder for the rest.
Bottom line
Neither account is “better” across the board. If you want simplicity and a strong rate with no minimum, a high-yield savings account usually wins. If you want check-writing or debit access and you hold a larger balance, a money market account can make sense. Either way, you’re doing far better than leaving cash in a checking account earning next to nothing.
