A money market account and a savings account are both interest-bearing deposit accounts at a bank or credit union, and at a federally insured institution both are covered by deposit insurance up to $250,000 per depositor, per institution, for each ownership category. The money market account usually adds check or debit card access and pays a higher rate at higher balances, while a savings account usually has a lower minimum and simpler rules. The comparison gets confusing because "money market" also names an investment fund that is not a bank account and carries no FDIC insurance.
Key takeaways
- A money market deposit account is a bank deposit insured by the FDIC (or by the NCUA at a credit union); a money market fund is an investment that has no FDIC guarantee and can lose value.
- Both account types are insured up to $250,000 per depositor, per institution, for each ownership category; money market funds are not.
- Since April 2020 federal rules no longer require banks to cap savings withdrawals at six per month, but your account agreement can still set its own limits and fees.
- The FDIC's national average rate on October 19, 2026 was 0.38% for savings and 0.63% for money market accounts, so the gap that matters is the one between specific accounts, not between the two account types.
- A higher money market rate can lose to a savings rate once a minimum-balance fee applies; compare the net return at your own balance.
Money market vs savings: the basics
The Consumer Financial Protection Bureau describes a money market account as a deposit account offered by banks and credit unions that tends to pay higher interest than other savings accounts. It may require a minimum deposit and usually limits the number of transactions you can make by check, debit card or electronic transfer, while ATM withdrawals are usually unlimited.
A regular savings account is built for setting money aside. It typically has no check writing and a lower or no minimum, though the terms are set by each institution.
| Feature | Savings account | Money market deposit account |
|---|---|---|
| Product type | Bank or credit union deposit | Bank or credit union deposit |
| Deposit insurance | FDIC or NCUA, up to $250,000 per depositor, per institution, per ownership category | FDIC or NCUA, same limit and rules |
| Everyday access | Transfers, often an ATM card; checks uncommon | Often checks and a debit card, with transaction limits set by the bank |
| Minimums | Often low or none | Often a minimum to open, avoid a fee or earn the top rate |
| Rate structure | Usually one rate or a few tiers | Often tiered by balance |
| Your agreement decides | Withdrawal limits, fees, rate tiers | Withdrawal limits, fees, rate tiers, check rules |
The table shows typical patterns, not rules. Some savings accounts have debit cards, and some money market accounts have no minimum. The account agreement and fee schedule are the documents that settle it.
Money market account vs fund
The two products share a name and little else. A money market deposit account is a bank deposit. A money market fund is a mutual fund, sold by brokerage firms and fund companies, that holds short-term debt.
An SEC investor bulletin last updated in 2010 says money market funds are different from the money market depository accounts banks offer: the accounts are guaranteed by the FDIC, while an investment in a money market fund has no FDIC guarantee. The same bulletin says a fund seeks to keep a stable share price, typically $1.00, but if the value falls below that level ("breaking the buck"), investors lose money. That description predates later reforms: under the current rule, only government and retail funds may keep a stable price (see the FAQ below). The CFPB makes the same split, calling a money market mutual fund account an investment, not a savings or checking account, even though some funds allow check writing.
Funds are regulated under SEC Rule 2a-7 (17 CFR 270.2a-7), which limits what they can hold, for example by capping the maturity of individual holdings at 397 days and the portfolio's average maturity at 60 days, and requiring at least 25% of assets in daily liquid assets (tax-exempt funds are excluded from this minimum) and 50% in weekly liquid assets. Those rules reduce risk but are not insurance.
The SEC changed how withdrawals work in reforms adopted on July 12, 2023. Funds can no longer suspend redemptions temporarily through a gate. Instead, any non-government money market fund must charge a discretionary liquidity fee on redemptions if its board decides a fee is in the fund's best interest, capped by the rule at 2% of the value of the shares redeemed. Institutional funds (neither government nor retail funds) must charge a fee when daily net redemptions exceed 5% of net assets (or a lower level set by the board), unless the fund's liquidity costs are de minimis. A bank deposit account's withdrawal fees, by contrast, are the ones set out in your account agreement.
Brokerage accounts that hold a fund fall under a different safety net. SIPC says money market mutual funds are protected as securities if a member brokerage fails, up to $500,000 including up to $250,000 of cash. SIPC does not cover a decline in the value of an investment, and it is not the same as FDIC insurance.
Deposit insurance for both accounts
The FDIC's rule is $250,000 per depositor, per FDIC-insured bank, for each account ownership category, such as single, joint or certain retirement accounts. Its main page states that deposits are insured to at least $250,000 at each FDIC-insured bank, and lists savings and money market deposit accounts among the covered products. Mutual funds, stocks and bonds are on its list of products that are not covered. At a federally insured credit union, the NCUA's Share Insurance Fund likewise insures individual accounts up to $250,000.
The CFPB adds that balances held by the same owner or owners at one institution can be aggregated, so check coverage if your total at a single bank or credit union is near the limit. A savings account and a money market account in your name alone at the same bank are added together, not insured separately. The account name does not change the limit, and both protections apply only if the institution itself is federally insured.
Withdrawal limits after Reg D
For decades, Regulation D, a Federal Reserve rule, defined a savings deposit partly by a limit of six convenient transfers or withdrawals per month. On April 24, 2020, the Fed announced an interim final rule that removed that limit from the definition, which, in the Fed's words, allows depository institutions to suspend enforcement of the six transfer limit. The Fed said the limit had been the basis for separating reservable transaction accounts from savings deposits, a distinction it called unnecessary after reserve requirements were cut.
The change lifted a federal requirement. It did not oblige every bank to drop its own limits. The CFPB notes that money market accounts usually cap check, debit card and electronic transfers, so read the "transaction limits" section of your agreement. Look for a monthly count, the fee for going over it and whether the bank can convert or close an account that repeatedly exceeds the limit.
Rates, tiers and minimum balances
The FDIC publishes national averages. As of October 19, 2026, its national rates page showed 0.38% for savings (based on a $2,500 product tier) and 0.63% for money market accounts (an average of the $10,000 and $100,000 tiers). The FDIC defines the national rate as the average of rates paid by insured banks and credit unions for which data is available, weighted by each institution's share of domestic deposits.
Those averages are far below what competitive accounts advertise, so they are a poor guide to what you can earn. On $10,000, a year at 0.38% is about $38 and at 0.63% about $63 (simple interest, rounded). The larger gap is usually between a bank paying the average and one paying much more, whatever the account type.
A money market account's tier structure is where the comparison turns. A rate shown as the "top" APY may apply only above a stated balance, and a monthly fee may be waived only above another one. Both numbers are in the rate sheet and fee schedule.
Worked example with round numbers
Illustrative example, not a real offer. Suppose a savings account pays 4.00% APY with no fee, and a money market account pays 4.25% APY with a $12 monthly fee waived at a $10,000 balance. Interest is approximated as balance × APY for one year, and the fee is $12 × 12 = $144 when it applies.
| Balance held all year | Savings (4.00%, no fee) | Money market (4.25%, $144 fee below $10,000) | Better by |
|---|---|---|---|
| $8,000 | $320 | $196 | Savings by $124 |
| $10,000 | $400 | $425 | Money market by $25 |
| $15,000 | $600 | $637.50 | Money market by $37.50 |
The money market account pays more on every dollar, yet at $8,000 it loses by $124 because of the fee, and above the waiver the advantage is small: $25 on $10,000. The rate gap matters less than whether you will stay above the threshold. Some fee schedules test the minimum daily balance rather than the average, so a single dip below the threshold can trigger that month's fee. Swap in the real rate, fee, minimum and balance test from the sheets you are comparing.
Choosing between the two
Match the account to how you will use the money.
- Bills paid from the account, or occasional checks: a money market account with check access can fit, if you will stay within its transaction limit.
- A balance that may dip below a minimum: a savings account with no minimum avoids fee risk, even at a slightly lower rate.
- A steady balance above the waiver level: the money market account's higher tier can be worth it.
- Money you may want invested rather than deposited: that is a money market fund, with the loss risk and brokerage account described above.
The two account types can also be used together at one institution. Balances in the same ownership category there are added together, and only $250,000 of that total is insured.

Frequently asked questions
Can I write checks from a money market account?
Many money market deposit accounts allow checks, but the CFPB says they usually limit how many transactions you can make by check, debit card or electronic transfer. ATM withdrawals are usually unlimited. Whether checks are included, and how many, is set by the bank, so confirm it in the agreement.
Are credit union money market accounts insured?
The CFPB says money market accounts at banks and credit unions are insured by the FDIC or the NCUA, up to $250,000 held by the same owner or owners. At a credit union, confirm that it is federally insured by the NCUA. The NCUA's insurance page lists share draft, share savings and share certificate accounts as examples of covered share deposits.
Why are the national average rates so low?
The FDIC's national rate is an average across all insured banks and credit unions with available data, weighted by their share of domestic deposits, so large institutions that pay little pull it down. The savings figure also reflects a $2,500 tier. An account that pays well above the average can still be FDIC-insured.
Do money market funds still keep a $1 share price?
Only some of them. Under Rule 2a-7, government funds (at least 99.5% of assets in cash, government securities or fully collateralized repurchase agreements) and retail funds (limited to individual investors) may use pricing methods that hold a stable share price. Other money market funds must price their shares to at least four decimal places, so the share value can move slightly. A stable price is a goal, not a guarantee, and neither kind of fund is a bank deposit.
Does the 2020 change mean savings withdrawals are unlimited?
Not automatically. The Fed's change let institutions stop enforcing the six-transfer limit, but the CFPB still describes transaction caps on money market accounts as usual. Your bank's current account agreement is the authority on any limit and any fee for exceeding it.
A checklist before you open one
- Write down the balance you expect to hold and the lowest it could fall.
- Find the APY at that balance on the rate sheet, not the top-tier rate.
- Note the monthly fee and the balance that waives it.
- Read the transaction-limit and excess-withdrawal sections of the agreement.
- Confirm that the product is a deposit account at an FDIC- or NCUA-insured institution, and not a fund.
- Compare net yearly interest after fees, as in the worked example.
