An MMA savings account combines features of a savings account and a money market account
An MMA savings account — sometimes called a money market account or money market savings account — is a hybrid deposit account that sits between a regular savings account and a money market fund. It typically offers a higher interest rate than a standard savings account, but comes with limits on how often you can withdraw money each month. The tradeoff is straightforward: you keep more of your money in the account longer, and the bank pays you more interest in return.
The account is FDIC-insured up to $250,000 (or $500,000 if you have a joint account), which means your money is protected by federal insurance if the bank fails. This makes it safer than investing in stocks or bonds, but the interest rate will typically be lower than what you could earn from those investments over time.
Banks and credit unions offer MMA savings accounts as a way to attract depositors who want better returns without taking investment risk. You'll find them at most major banks, online banks, and credit unions, though the interest rates and withdrawal rules vary by institution.
Key Takeaways
- An MMA savings account pays higher interest than a regular savings account but limits how many times per month you can withdraw money.
- Your deposits are insured by the FDIC up to $250,000, protecting your principal if the bank fails.
- Most MMA accounts require a minimum opening deposit, which ranges from $0 to $25,000 depending on the bank.
- Interest rates on MMA accounts change with the Federal Reserve's rate decisions and vary widely between banks, so shopping around matters.
- Withdrawal limits are typically six transactions per month, and exceeding them may result in fees or account closure.
How the interest rate works on an MMA account
The interest rate on an MMA savings account is variable, meaning it changes over time. Banks set their rates based on the Federal Reserve's benchmark interest rate, which they adjust several times per year. When the Fed raises rates, banks usually raise MMA rates within weeks. When the Fed cuts rates, MMA rates typically fall as well.
The actual rate you receive depends on the bank and how much money you have in the account. Some banks offer tiered rates — a higher percentage if you maintain a larger balance. For example, one bank might pay 0.50% on balances under $10,000 and 1.25% on balances of $100,000 or more. Online banks tend to offer higher rates than brick-and-mortar banks because they have lower overhead costs.
Interest is usually compounded daily and credited to your account monthly. This means you earn interest on your interest, which compounds over time. The longer your money sits in the account, the more this compounding effect works in your favor.
Withdrawal limits and how they affect your money
Most MMA savings accounts limit you to six withdrawals or transfers per month. This rule comes from federal banking regulations, though some banks enforce it more strictly than others. The limit applies to transfers out of the account — whether you're moving money to another bank, writing a check, or using a debit card linked to the account.
If you exceed the withdrawal limit, the bank may charge a fee (typically $10 to $25 per excess withdrawal) or close your account. Some banks will simply deny the transaction. This is why an MMA account works best for money you plan to leave alone for at least a few months — not for everyday spending.
ATM withdrawals and in-person withdrawals at a branch usually do not count toward the limit, so you can still access your cash if you need it urgently. Check your bank's specific rules before opening an account, because policies vary.
Minimum deposit requirements vary by bank
Most banks require a minimum opening deposit to start an MMA account, but the amount ranges widely. Online banks often have no minimum or a very low minimum ($0 to $500), while traditional banks may require $1,000 to $25,000 to open. Some banks also require you to maintain a minimum balance to keep the account open or to earn the advertised interest rate.
If you fall below the minimum balance, the bank may charge a monthly fee, drop your interest rate to a lower tier, or close the account. Read the account terms carefully before opening, because these rules are not always obvious in marketing materials.
Online banks tend to have lower minimums because they serve a broader customer base and can operate with thinner profit margins. If you have a small amount to save, an online bank's MMA account may be a better fit than a local bank's.
When an MMA account makes sense for your savings
An MMA account works well if you have money you want to keep safe and earn interest on, but you do not need to access it frequently. Common uses include building an emergency fund, saving for a down payment on a home, or setting aside money for a large purchase planned six months or more away.
An MMA account is less useful if you need to move money in and out regularly, because the withdrawal limits will frustrate you and may trigger fees. For everyday spending and bill payments, a regular checking account is the right tool. For money you will not touch for years, a CD (certificate of deposit) often pays a higher rate because you commit to leaving the money untouched for a fixed period.
The decision also depends on current interest rates. When rates are high (above 4% or 5%), an MMA account becomes more attractive because you earn meaningful returns. When rates are very low (below 1%), the difference between an MMA account and a regular savings account shrinks, and the withdrawal limits become less worth the tradeoff.
How to compare MMA accounts across banks
Start by listing the features that matter to you: the interest rate, the minimum deposit, the withdrawal limit, and whether the bank charges monthly maintenance fees. Then visit the websites of at least three to five banks — both online and traditional — and write down their current rates and terms.
Pay attention to the Annual Percentage Yield (APY), not just the interest rate. APY includes the effect of compounding and tells you the true return you will earn over a year. A bank advertising a high rate but compounding only annually may deliver less than a bank with a slightly lower rate that compounds daily.
Check whether the rate is promotional (good for a limited time only) or ongoing. Some banks offer high rates for the first three months to attract new customers, then drop the rate significantly. Read the fine print or call the bank to confirm how long the advertised rate lasts.
Frequently Asked Questions
Can I use a debit card to withdraw from an MMA account?
Most banks allow debit card withdrawals from MMA accounts, but these count toward your monthly withdrawal limit. Some banks offer a debit card specifically for the account; others require you to transfer money to a checking account first. Ask your bank before opening the account if this matters to you.
What happens if I exceed the withdrawal limit?
The bank may charge a fee per excess withdrawal (usually $10 to $25), deny the transaction, or close the account if you repeatedly exceed the limit. Some banks are lenient; others enforce the rule strictly. Check your account agreement or call the bank to understand their specific policy.
Is my money safe in an MMA account?
Yes, up to $250,000 per account holder. The FDIC insures MMA accounts the same way it insures regular savings accounts. If the bank fails, the federal government guarantees your deposits up to the limit. Money in an MMA account is safer than money in stocks or bonds.
Can I move money from my MMA account to a checking account without hitting the withdrawal limit?
Transfers between accounts at the same bank typically count toward the six-transaction limit, though some banks treat transfers to your own checking account differently. Call your bank to confirm their specific rules before opening the account.
Should I open an MMA account or a CD instead?
A CD usually pays a higher rate but locks your money away for a fixed term (three months to five years). An MMA account pays less but lets you access your money anytime (within the withdrawal limit). Choose a CD if you know you will not need the money for a specific period; choose an MMA account if you want flexibility.
