Driven by the arrival of online banking and a competitive rate environment, high-yield savings accounts (HYSAs) became prominent in the mid-2000s. Money market accounts (MMAs) have been around since the 1980s and offer healthy returns, as well.
At first glance, the two accounts seem almost interchangeable. But there are key differences that can determine which option is better for you.

What's a high-yield savings account?
An HYSA is a savings account with a higher APY than a traditional savings account, often more than 10 times as high.
HYSAs are often offered by digital-first institutions, which have less overhead and are interested in attracting customers to other financial products, and by credit unions, which reinvest profits in better returns for members.
Funds in an HYSA are fairly liquid, but you may need to transfer money to an external bank first, which can take one to three business days.
Some banks also cap withdrawals from HYSAs at six per month.
What's a money market account?
A money market account is a deposit account that combines the interest of a savings account with features more commonly found in a checking account, such as check-writing and debit cards.
MMAs are commonly offered by brick-and-mortar banks and credit unions.
Money market account vs. HYSA: What's the difference?
Both HYSAs and MMAs have healthy APYs and are FDIC-protected for up to $250,000 per person, per bank, and per account type. And unlike a CD, you can easily deposit and withdraw money from either. But there are differences to look out for.
Minimum balance requirement
While HYSAs usually have no (or low) minimum balance requirements, MMAs may require you to keep anywhere from a few hundred to several thousand dollars in your account.
Ally Bank's MMA has no minimum balance requirement, though, and no maintenance fees, either.

Check-writing and debit cards
If you want the accessibility of a checking account, only an MMA lets you write checks and use a debit card linked to the account. With an HYSA, , you have to transfer the cash to your checking account, which can take up to three days to clear.
MMA vs. HYSA: Which should you choose?
There are pluses and minuses to both money-market accounts and high-yield savings accounts.
The minimum balance requirement is perhaps the biggest issue with an MMA. It also makes them less well-suited for an emergency fund, since you don't know when or how much you'll need in a pinch.
If you're worried about meeting a minimum requirement or that an emergency will leave you incurring monthly maintenance fees, opt for a high-yield savings account. CNBC Select consistently recommends the Marcus by Goldman Sachs High Yield Online Savings account, which doesn't charge fees for overdrafts, excessive transactions or monthly maintenance.

FAQs
Which is better, a money market account or a high-yield savings account?
Whether an MMA or HYSA is better for you depends on your needs. If you're focused on a high APY, with no fees or balance requirements, an HYSA is probably your best bet. If you want debit card access and the perks of a brick-and-mortar bank, go for a money-market account.
How much will $100,000 earn in a money market account after a year?
The best money market accounts earn at least 4% APY. At that rate, $100,000 would earn roughly $4,000 in interest over 12 months.
Is there a downside to a high-yield savings account?
High-yield savings accounts have variable interest rates, so you can lose out on potential earnings at any time. They're also commonly offered by online banks, which can lack the customer service and robust financial offerings of brick-and-mortar banks. Unlike MMAs, most HYSAs don't come with debit card or check-writing privileges, so access to funds is more limited.
Can you have both a MMA and a HYSA, or should you pick just one?
Yes, you can have both a MMA and a HYSA. A common approach is to keep your emergency fund in a HYSA, where there's no minimum balance to worry about, and use a MMA for funds you want to access quickly via debit card or check, like money earmarked for a near-term purchase.
How much can you contribute to a HYSA?
There isn't technically a limit to how much you can contribute to a HYSA, however, accounts are only FDIC-insured for up to $250,000, so it isn't a good idea to keep more than that in a HYSA.
