A money market savings account combines features of checking and savings accounts, with higher interest rates in exchange for larger minimum balances and limits on withdrawals
A money market savings account is a hybrid deposit account offered by banks and credit unions. You deposit money, earn interest on the balance, and can withdraw funds—but with restrictions that traditional savings accounts don't have. The trade-off is that interest rates are typically higher than regular savings accounts, sometimes significantly so, because the bank uses your money for short-term lending and investments.
The account sits between a regular savings account and a money market fund (which is an investment product, not a bank account). With a money market savings account, your deposits are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank. That insurance does not apply to money market funds.
You access your money through a debit card, checks, or transfers—but the account typically limits how many withdrawals you can make per month. Federal rules previously capped this at six per month, though that rule was suspended in 2020 and banks now set their own limits. Some allow unlimited transfers; others still enforce monthly caps. Check your bank's specific terms before opening.
Key Takeaways
- Money market savings accounts require a higher minimum deposit than regular savings accounts, often $2,500 to $25,000 depending on the bank.
- Interest rates are higher than savings accounts but fluctuate with market conditions and your bank's policies; rates vary widely between institutions.
- You can access funds through debit card, checks, or transfers, but most accounts limit the number of withdrawals per month.
- Your deposits are FDIC-insured up to $250,000, making this a low-risk place to hold money you may need within a year or two.
- The interest you earn is taxable income and will be reported to the IRS on a 1099-INT form if annual interest exceeds $10.
Minimum balance requirements and how they affect your account
Most money market savings accounts require you to maintain a minimum balance to earn the advertised interest rate and avoid monthly fees. This minimum varies by bank and account tier. Some banks set it at $2,500; others require $10,000 or $25,000. A few online banks have no minimum, but these are less common.
If your balance falls below the minimum, two things can happen: your interest rate drops to a lower tier, or you pay a monthly maintenance fee (typically $10 to $25). Some banks do both. Read the disclosure document before opening—it will specify what happens at each balance level and what the fee is. If you cannot reliably keep the minimum, a regular savings account or high-yield savings account may be a better fit.
The minimum also affects how much you need to deposit upfront. If you have $5,000 to save but the account requires $10,000 to earn the top rate, you will either earn a lower rate on your $5,000 or pay a fee each month. Calculate whether the higher interest rate on the full amount you can deposit will outweigh any fees you might incur.
Interest rates and how they compare to other savings products
Money market savings accounts typically pay more interest than regular savings accounts at the same bank. As of early 2024, regular savings accounts at major banks earn around 0.01% to 0.05% annually, while money market accounts at those same banks earn 0.10% to 0.50%. Online banks and credit unions often offer higher rates across both account types, sometimes 4% to 5% on money market accounts, though rates change frequently based on Federal Reserve policy.
The interest rate you receive depends on three things: the bank's current rate, your account tier (which usually depends on your balance), and market conditions. Banks adjust rates periodically, sometimes monthly. You will not see the rate locked in for a year—it is variable. This means your earnings can increase if rates rise, or decrease if rates fall.
To compare accounts, look at the Annual Percentage Yield (APY), not just the interest rate. APY accounts for how often interest is compounded and deposited, so it shows your true annual return. A bank advertising 4.50% APY will earn you more than one advertising 4.50% interest rate compounded quarterly. Most banks compound and credit interest daily or monthly.
Withdrawal limits and how they work in practice
Money market savings accounts restrict how often you can withdraw money. Federal rules no longer cap this at six per month, but individual banks still enforce their own limits. Some allow six withdrawals monthly; others allow unlimited transfers but limit checks or debit card withdrawals to three or six per month. A few online banks allow unlimited everything.
The limit typically applies to transfers and withdrawals combined—meaning if you transfer $500 out and write a check for $300, that counts as two of your allowed transactions. Deposits do not count against the limit. ATM withdrawals usually count as one transaction regardless of how much you withdraw.
If you exceed the limit, the bank may refuse the transaction, charge a fee (usually $10 to $25 per excess withdrawal), or convert your account to a regular checking account with no interest. Check your bank's specific policy. If you need to access your money frequently, a regular savings account or checking account is more practical than a money market account.
When a money market account makes sense for your situation
A money market savings account works best if you have a lump sum of money you want to keep safe and earning interest, but you do not need to touch it often. Common scenarios include: saving for a down payment on a home (12 to 36 months away), building an emergency fund beyond your checking account, holding a tax refund or bonus, or parking money temporarily while you decide what to do with it.
It also makes sense if you can meet the minimum balance requirement without strain. If you have $15,000 in savings and the account requires $10,000 minimum, keeping $10,000 in the money market account and $5,000 in a checking account gives you both the higher rate and access to cash. But if you have only $5,000 total and the minimum is $10,000, you will either pay fees or earn a reduced rate, which defeats the purpose.
Money market accounts are less useful if you need frequent access to your money, if you cannot meet the minimum balance, or if you are saving for a goal more than five years away. For longer-term goals, a certificate of deposit (CD) often pays more interest. For frequent access, a high-yield checking account or high-yield savings account with no withdrawal limits is better.
FDIC insurance and what happens if the bank fails
Deposits in a money market savings account are insured by the FDIC up to $250,000 per depositor, per bank. This means if the bank fails, the FDIC will return your money up to that limit. You do not need to do anything to activate this insurance—it is automatic for all deposit accounts at FDIC-member banks.
If you have more than $250,000 at one bank, only $250,000 is insured in each account category. Money market savings accounts are one category; checking accounts are another; savings accounts are another. So if you have $200,000 in a money market account and $100,000 in a savings account at the same bank, both are fully insured because they are in different categories. But if you have $300,000 in a money market account at one bank, only $250,000 is insured.
Credit unions offer similar protection through the National Credit Union Administration (NCUA), also up to $250,000 per account type. If you are concerned about exceeding the insurance limit, you can open accounts at multiple banks or credit unions, and each institution's coverage is separate.
Tax treatment of interest earned in a money market account
Interest you earn on a money market savings account is taxable income. You must report it on your federal tax return in the year you earn it, even if you do not withdraw the money. The bank will send you a Form 1099-INT in January if your interest exceeds $10 during the prior year. You use this form to complete your tax return.
The interest is taxed at your ordinary income tax rate, which varies based on your total income and tax bracket. If you earn $500 in interest and you are in the 24% tax bracket, you will owe approximately $120 in federal tax on that interest (plus any state income tax, depending on where you live). This is one reason why the interest rate matters: a 4% rate on $10,000 earns $400 per year, but after taxes you keep roughly $300 to $320 depending on your bracket.
If you are saving for retirement, a money market account inside a traditional IRA or Roth IRA can reduce or eliminate this tax burden. Interest earned inside an IRA is not taxed until you withdraw it (traditional IRA) or not taxed at all (Roth IRA). But IRAs have annual contribution limits and withdrawal rules, so they are not suitable for all savings goals.
Frequently Asked Questions
Can I use a money market account as my main checking account?
Technically yes, since most offer debit cards and checks, but it is not practical. The withdrawal limits make it inconvenient for daily spending, and the higher minimum balance requirement ties up money you might need for regular bills. Use a checking account for daily expenses and a money market account for money you plan to keep separate.
What happens if I go below the minimum balance?
The bank will either charge you a monthly fee (usually $10 to $25), drop your interest rate to a lower tier, or both. Some banks convert the account to a regular savings account. Check your account agreement to see what your bank does. If you frequently dip below the minimum, the fees will erase any interest you earn.
Is a money market account the same as a money market fund?
No. A money market savings account is a bank deposit account insured by the FDIC. A money market fund is an investment product that buys short-term debt securities and is not FDIC-insured. Money market funds can lose value; money market savings accounts cannot. They are different products with different risks.
How often do interest rates change on money market accounts?
Banks can change rates at any time, though most adjust them monthly or quarterly in response to Federal Reserve policy changes. You will not know the exact date in advance. Some banks notify you by email; others post the new rate on their website. Check your account online or call the bank if you want to know the current rate.
Can I move money between my money market account and checking account without it counting as a withdrawal?
It depends on the bank. Most banks count transfers between your own accounts as withdrawals for the purpose of the monthly limit. Some online banks do not. Ask your bank specifically whether internal transfers count. If they do, you may want to keep your money market account separate and only move money out when necessary.
