A high yield money market account is a bank deposit account that pays well above the average money market rate and often lets you write checks or use a debit card. It is FDIC insured up to $250,000 like a savings account, but it often needs a higher balance to earn its best rate. The FDIC national average money market rate was 0.63% as of Oct 19, 2026; the top savings rate we track is 4.40% APY.
Money market accounts sit between checking and savings. They pay interest like savings, but many come with a way to spend directly from the account. Here is how they work and when one makes more sense than a high yield savings account.
How does a money market account work?
You deposit money and earn a variable rate, the same as a savings account. The bank can change the rate at any time. What sets a money market account apart is access: many let you write checks, use a debit card or both. Some pay higher rates on larger balances, called tiers, and some require a minimum balance to avoid a fee or to earn the advertised rate.
“High yield” is a marketing term, not a legal one. It usually means an online bank account paying many times the national average.
Money market account vs. high yield savings account
| Money market account | High yield savings account | |
|---|---|---|
| Rate | Variable, often tiered by balance | Variable, often one rate for any balance |
| Access | Often checks and a debit card, plus transfers | Usually transfers only |
| Minimums | Often higher to open or to earn the top rate | Often $0 or low |
| Insurance | FDIC (banks) or NCUA (credit unions), up to $250,000 | FDIC (banks) or NCUA (credit unions), up to $250,000 |
| National average rate | 0.63% (FDIC, Oct 19, 2026) | 0.38% (FDIC, Oct 19, 2026) |
If you want the highest rate and only move money a few times a year, a high yield savings account is usually the simpler choice. If you want to pay a large bill straight from the account, such as a tax payment or a contractor, a money market account with checks can save a transfer.

Money market account vs. money market fund
The names are close, but they are different products:
- A money market account is a bank or credit union deposit. It is FDIC or NCUA insured up to the limits.
- A money market fund is a mutual fund sold by brokerages. It invests in short term debt, aims to hold a steady $1 share price and is not FDIC insured. It can lose value, although that is rare.
If a brokerage shows you a “money market” yield, check which one it is before you compare it with a bank rate.
Are there withdrawal limits?
For years, federal rules limited savings and money market accounts to six certain withdrawals or transfers a month. In April 2020 the Federal Reserve removed that limit, but banks can still set their own limits and fees. Check the account terms before you open one if you plan to use it often.
Who is a money market account good for?
- People who want an emergency fund they can spend from directly with a check or debit card.
- Savers with larger balances who can reach a top tier.
- Anyone who wants one account for both saving and occasional large payments.
