The core difference: interest rate, withdrawal limits, and minimum balance

A money market account pays a higher interest rate than a regular savings account, but it comes with strings attached. You get that higher rate because the bank can lend out more of your money—which means you face withdrawal limits, a higher minimum balance requirement, and sometimes a tiered rate structure where you earn more only if you keep a larger balance.

A regular savings account has no withdrawal limit, no minimum balance (or a very low one), and a fixed interest rate that applies to every dollar you deposit. The trade-off is straightforward: easier access and fewer rules in exchange for less money earned.

The interest rate difference matters only if you're comparing accounts at the same bank or at banks offering similar rates. Shop around—a high-yield savings account at an online bank often pays more than a money market account at a traditional bank, even though the money market account has more restrictions.

Key Takeaways

  • Money market accounts typically pay 4% to 5% annual interest (rates vary by bank and change weekly), while regular savings accounts at brick-and-mortar banks usually pay 0.01% to 0.05%.
  • Most money market accounts limit you to six withdrawals per month or charge a fee if you exceed that limit; regular savings accounts have no withdrawal cap.
  • Money market accounts require a minimum opening balance—often $2,500 to $25,000—while regular savings accounts may have no minimum or require $100 or less.
  • Some money market accounts use tiered rates, meaning you earn a higher percentage only on balances above a certain threshold, so a smaller deposit earns almost nothing.
  • An online high-yield savings account can pay more than a money market account without the withdrawal restrictions, making it worth comparing before you choose.

How withdrawal limits work and why they exist

Federal banking rules once capped withdrawals from money market accounts at six per month. That rule was suspended in 2020, but many banks kept the limit anyway because it protects their lending model. When you deposit money in a money market account, the bank lends most of it out. If too many customers withdraw at once, the bank has to call in loans or sell assets quickly, which costs money.

If you exceed the withdrawal limit, the bank charges a fee—typically $25 to $35 per excess withdrawal. Some banks will freeze the account or convert it to a regular savings account if you repeatedly go over the limit. A regular savings account has no such restriction; you can withdraw as often as you want, though some banks may flag unusual activity.

The withdrawal limit applies to transfers out of the account, not deposits in. You can deposit money as many times as you want. The limit also usually does not apply to ATM withdrawals at the bank's own machines, only to transfers to other banks or checks written against the account.

Minimum balance requirements and tiered interest rates

A money market account typically requires $2,500 to $25,000 to open, depending on the bank. If your balance falls below the minimum, the bank may charge a monthly fee ($10 to $25) or drop your interest rate to match a regular savings account. A regular savings account often requires nothing or $100 or less.

Many money market accounts use tiered rates. For example, a bank might pay 4.50% on balances of $25,000 or more, 4.25% on balances of $10,000 to $24,999, and 3.75% on balances below $10,000. If you deposit $5,000, you earn the lowest tier rate on all of it. This structure rewards large depositors and penalizes smaller ones.

Regular savings accounts typically have one rate that applies to your entire balance, no matter how much you have. Some online banks offer no minimum balance at all and pay the same rate to everyone.

Interest rates: what you actually earn and how often it changes

Money market account rates move with the Federal Reserve's benchmark rate and change weekly or even daily. When the Fed raises rates, your money market rate usually rises within days. When the Fed cuts rates, your money market rate falls just as fast. A regular savings account rate also moves with the Fed, but banks change it less frequently—sometimes only once a month or once a quarter.

Right now, money market accounts at major banks pay between 4% and 5% annual interest, while regular savings accounts at the same banks pay 0.01% to 0.05%. Online banks offer higher rates on both products, but the gap between money market and regular savings is usually smaller at online banks because they have lower overhead.

The interest rate you see advertised is the annual percentage yield (APY). This is the rate you actually earn, including compounding. Banks calculate interest daily and add it to your account monthly or daily, depending on the account. The more often interest compounds, the more you earn—but the difference is small unless your balance is very large.

When a money market account makes sense

Use a money market account if you have at least $10,000 to $25,000 sitting in savings and you do not need to touch it more than six times a month. This works well for an emergency fund you want to keep separate from checking, or for money you are saving toward a specific goal six months or more away.

Do not use a money market account if you need frequent access to your money. The withdrawal limit and fees will cost you more than you earn in extra interest. Also do not use one if your balance will regularly fall below the minimum—the monthly fee will wipe out your interest gains.

Before opening a money market account, compare it to a high-yield savings account at an online bank. Many online banks pay 4.5% to 5.35% on regular savings accounts with no minimum balance, no withdrawal limit, and no tiered rates. You might earn more and have fewer restrictions.

How to move money between accounts without hitting withdrawal limits

If you have a money market account and need to move money out, use your bank's internal transfer system to move it to your checking account first, then withdraw from checking. Most banks do not count transfers between your own accounts toward the withdrawal limit. Check your account agreement or call the bank to confirm.

If you need to send money to someone else, use your bank's bill pay or external transfer feature. Some banks count these as withdrawals; others do not. The rule varies by bank and by account type. Ask before you transfer, or you may trigger a fee.

ATM withdrawals at your bank's own machines usually do not count toward the limit. Withdrawals at other banks' ATMs or at third-party networks may count. Again, check your agreement or call.

Switching from a regular savings account to a money market account

If you have been saving in a regular account and now have enough to meet a money market minimum, moving your money is simple. Open the money market account at the same bank or a different one, then transfer your balance from the old account. The transfer usually takes one to three business days.

You do not lose any interest during the transfer. Interest accrues daily, so you earn it up to the day you move the money. The new account starts earning its rate on the day the funds arrive.

Keep the old account open for at least 30 days after the transfer, in case the bank needs to reverse the transaction. After that, you can close it. Closing an account does not hurt your credit score.

Frequently Asked Questions

Can I write checks on a money market account?

Some money market accounts come with a checkbook or debit card, but most do not. If your account includes checks, writing them usually counts toward your six-withdrawal limit. Call your bank to confirm before you write a check.

What happens if I go over the withdrawal limit?

The bank charges a fee, usually $25 to $35 per excess withdrawal. If you repeatedly exceed the limit, the bank may convert your account to a regular savings account or close it. The fee is charged immediately, so you see it on your next statement.

Do I pay taxes on money market account interest?

Yes. Interest earned on a money market account is taxable income. The bank sends you a 1099-INT form at the end of the year if you earned $10 or more in interest. You report this on your tax return.

Is my money safe in a money market account?

Yes. Money market accounts are covered by FDIC insurance up to $250,000 per depositor per bank. This means if the bank fails, the government guarantees your money up to that limit. Regular savings accounts have the same protection.

Can I lose money in a money market account?

No. Money market accounts are not investments. Your balance does not go down unless you withdraw it or the bank charges a fee. The interest rate can fall, but your principal is safe.
