Under the federal rule that classifies bank deposits, a money market account and a savings account are the same thing. Both are "savings deposits" under Regulation D: the bank may require seven days' notice before a withdrawal, the deposit has no maturity date, and — since the Federal Reserve deleted the six-transfer limit in April 2020 — the definition no longer cares how many transfers you make or how you make them. Nothing in that rule says a money market account must pay more, allow cheques, or require a larger balance. Every difference between the two is a product decision by the bank that sells them.
That is the useful way to read the comparison. This page sets a money market account against the plain savings account most people already hold at a branch bank — the one opened alongside a checking account, with a small monthly fee and a rate nobody has looked at in years. It is not about high-yield savings accounts at online banks: money market vs high-yield savings covers that pairing, and the money market fund, which is not an account at all. What follows is what a bank changes to turn one deposit into the other — the minimum, the fee, the rate structure, the access — and the small print on transfers that outlived the 2020 rule.
Same deposit, different label
Regulation D, at 12 CFR 204.2(d), defines a savings deposit as one on which the depositor is not required to give notice but from which the bank "may at any time" require seven days' written notice of an intended withdrawal, and which is not payable on a fixed date. The second paragraph of that definition, as it reads today, covers transfers and withdrawals to another account or to a third party "regardless of the number of such transfers and withdrawals or the manner in which such transfers and withdrawals are made". Before 24 April 2020 that paragraph carried the six-per-month limit on convenient transfers, and until 2 July 2009 the rule also capped cheque and card payments at three of the six. How a money market account works traces the history; the point here is where it leaves the two accounts: legally identical, and different only in the contract each bank writes.
Three consequences follow, and they organise the rest of this page.
The name tells you nothing. A bank may call a cheque-writing, tiered-rate deposit with a $12 fee a "platinum savings account", and a card-only deposit with a $12 fee a "money market account". Both structures were on large banks' sites when this page was checked; neither bank is named here, by house rule. What counts is the account disclosure, which Regulation DD requires the bank to give you before the account is opened, and which must state the rate, the minimum balances, the fees and the transaction limits.
Insurance is identical. The FDIC's list of covered products names "Savings accounts" and "Money market deposit accounts (MMDAs)" side by side, and the same $250,000 per depositor, per insured bank, per ownership category applies to both. The two accounts share that limit rather than doubling it, which is covered below.
The 2020 change permitted; it did not require. The Federal Reserve's own FAQ says the rule "permits depository institutions to suspend enforcement of the six-transfer limit, but it does not require depository institutions to do so", and that Regulation D neither requires nor prohibits fees for transfers and withdrawals over the six-transfer limit. Either account can still carry a limit the bank sets itself. Whether yours does is in the disclosure, not in the rule.
What actually differs, on the terms banks write
| Feature | Plain branch-bank savings | Money market account |
|---|---|---|
| Monthly fee | Typically $5 to $8, waived by a few hundred dollars of balance, a linked checking account, a small automatic transfer, or age | Typically $10 to $12, waived by a balance in the thousands to $10,000, or by a linked checking account of a stated tier |
| Rate structure | One variable rate, sometimes with a relationship boost | Usually tiered by balance, with several breakpoints; sometimes a promotional rate for new money |
| Cheques | No | At some banks; others give a card only |
| Card and ATM | Often an ATM card; debit through a linked checking account | ATM or debit card at most |
| Transfer limits | The bank's own — none listed on the four branch-bank savings schedules checked; one deposit agreement states withdrawals may be made regardless of number | The bank's own — six restricted transfers per monthly period with a $3 fee each above it, or ten per cycle with account closure, observed |
| Opening deposit | $0 to $100 | $0 to $100 |
| Insurance | FDIC or NCUA, $250,000 per depositor, per institution, per ownership category | The same, and it shares the limit with a savings account in the same category |
| Sold by | Branch banks, credit unions, online banks | The same |
The dollar figures are the structures on large banks' product pages on 10 September 2026, given for the shape of the thing and not as a rate sheet. No rate appears in the table, because no rate printed on this site would survive a month. Money market account rates explains how to read one and verify it at the bank in five minutes.
Where the money market rate comes from
The plain savings account at a branch bank is priced for money that does not move. Its holders opened it alongside checking, keep a modest balance in it, and rarely compare. The bank funds loans with that money cheaply and has little reason to pay up for it. The money market account is priced for the other kind of money: larger balances that could leave for a competitor, a brokerage, or a Treasury bill. So it is tiered — the bank pays more as the balance rises, because that is the money it is bidding for — and it is where the promotional rate lives.
Regulation DD defines a tiered-rate account as one with "two or more interest rates that are applicable to specified balance levels", and its Appendix A allows two ways of applying them. Under Method A, the rate for your tier applies to the whole balance. Under Method B, each rate applies only to the portion of the balance inside its tier, and the bank must disclose a range of yields for every tier above the first rather than a single number. The account disclosure says which method the bank uses.
The difference is not academic. Take an illustrative money market account paying 1.00% on balances to $10,000 and 2.50% above that, and a balance of $15,000, simple interest for a year:
| Illustrative tiers — not any bank's rates | Interest on $15,000 |
|---|---|
| Method A: 2.50% on the whole balance | $375 |
| Method B: 1.00% on the first $10,000, 2.50% on the next $5,000 | $225 |
Same advertised top tier, $150 apart. Under Method B, a balance one dollar over the breakpoint earns the higher rate on one dollar. The "up to" in a money market advertisement is usually the top tier, and the tiering method decides whether it is reachable on most of your money at all. APR vs APY covers how the yield figure is built from the rate; the tiering method is the piece that page does not cover, which is why it sits here.
One more thing about the official baseline. The FDIC publishes a national average for savings and a separate one for money market accounts, and computes them on different balance tiers — savings on the $2,500 tier, money market as an average of the $10,000 and $100,000 tiers. Even the two official averages are not measuring the same saver. The hub, high-yield money market accounts, prints the money market figure with its effective date; open the FDIC's table for the savings row alongside it, and read the gap as a difference in the money being measured as much as in the product.
The fee decides the outcome on small balances
Because the money market waiver line is set in the thousands and the savings waiver line in the hundreds, the fee is the first arithmetic to do, and on a small balance it is the only arithmetic that matters. The figures below are illustrative and chosen to be round; they are not any bank's rates, and the wide spread between them is the observed shape of branch-bank pricing, not a forecast of anything.
| Illustrative: savings at 0.05%, money market at 2.50% with a $10 monthly fee below $10,000 | Savings interest | Money market interest | Money market fees | Money market net |
|---|---|---|---|---|
| $3,000 | $1.50 | $75 | $120 | −$45 |
| $9,000 | $4.50 | $225 | $120 | $105 |
| $12,000 (fee waived) | $6 | $300 | $0 | $300 |
Simple interest, one year, before tax. Three things fall out.
Below $4,800, the illustrative money market account loses money outright — the fee exceeds the interest — and a plain savings account that earns almost nothing still wins by not charging. At about $4,900 the two are level. Above that, the money market account is ahead even while paying the fee, and once the balance clears the waiver line the gap is the whole spread. The waiver line, not the rate, is the number to hold in your head.
The plain savings account has a fee of its own, and on a very small balance it is the worse of the two. A $250 balance sitting under a $300 waiver line pays about $60 a year on an illustrative $5 monthly charge and earns about 13 cents. The waiver conditions — a linked checking account, a $25 monthly automatic transfer, the holder's age — are therefore the most valuable feature of the account, and most people who hold one are meeting a waiver without knowing which.
Access: cheques, cards, and the limits that outlived the rule
The functional reason to hold a money market account rather than a savings account is that you can pay from it directly. At some banks that means a cheque book; at others a debit or ATM card. At one large branch bank checked for this page it means a card and no cheques; at one online bank it means both. The plain savings account is reached by transfer — to the linked checking account, and from there to the world — with an ATM card sometimes offered for cash.
That access comes with the limits the 2020 rule left in place. Observed on 10 September 2026: a branch-bank money market account allowing six restricted transfers — cheque, card purchase, automatic, telephone or online — per monthly service-charge period and charging $3 for each one beyond that, with ATM and in-person withdrawals uncounted; an online money market account allowing ten transfers, cheques and card payments per statement cycle, charging no fee for exceeding it but reserving the right to close the account for doing so more than occasionally; and, on the two largest branch banks' plain savings accounts, no such fee on their current schedules: one deposit agreement now states that transfers and withdrawals may be made regardless of their number, and the other's schedule of fees lists none. A saver who makes nine such transfers out of that money market account in a month pays three fees; at $3 each that is $9, and $108 a year if the habit persists. Regulation DD requires transaction limitations to be in the account disclosure, so the figure for your account is knowable before you open it.
The principle from checking vs savings account applies to both: neither is a second checking account, and the one with a cheque book is the one more likely to be treated as one. A money market account that is written on weekly is a checking account with a higher minimum and a transfer limit.
Insurance is the same, and shared
Both accounts are deposits, and the FDIC covers both to $250,000 per depositor, per insured bank, per ownership category. The limit is per category, not per account: a $150,000 savings account and a $150,000 money market account, both in your sole name at one bank, are $300,000 in the single-ownership category, with $50,000 above the limit. Opening the second account at the same bank adds access and a rate; it adds no coverage. Are money market accounts FDIC insured works through the ownership categories and the brokerage sweep case. The distinction that matters more than either — the money market fund, which is an SEC-regulated mutual fund, not a deposit and not insured — is set out on money market vs high-yield savings and is not re-argued here.
At a credit union both products are share accounts, insured by the National Credit Union Administration through the National Credit Union Share Insurance Fund — a different agency from the one that insures banks — at $250,000 per member, per insured credit union, per ownership category, backed by the full faith and credit of the United States. The NCUA's own brochure lists "regular shares, share drafts (similar to checking), money market accounts, and share certificates" as the accounts a member's single-ownership coverage spans, so a credit union money market account and a share savings account share one limit exactly as the bank versions do.
What can change, and what notice you get
Both accounts are variable-rate. Regulation DD's definition of a variable-rate account is one whose rate "may change after the account is opened", unless the bank contracts to give at least 30 calendar days' advance written notice of rate decreases — read your agreement for that clause, and without it the rate can fall the same day. The change-in-terms rule requires 30 calendar days' notice of a change that "may reduce the annual percentage yield or adversely affect the consumer", and then exempts "changes in the interest rate and corresponding changes in the annual percentage yield in variable-rate accounts". So: a new fee, a higher waiver line, a tighter transfer limit — 30 days' notice. The rate falling — none. That is the same on both accounts, and it is why a money market account's higher rate is a fact about today rather than a term of the contract. A rate that needs fixing is a certificate of deposit, and CD vs money market account prices that trade.
Promotional rates are the money market account's particular habit. An advertisement must state the period for which a yield is offered or the date it is accurate, the minimum balance needed to earn it, and that fees could reduce earnings. A promotional rate for new money — a stated sum deposited within a stated number of days of opening — is the common form, and it reverts to the standard tier on a date you should diarise before you open.
Which fits what
The plain savings account fits a modest balance that a waiver condition keeps fee-free — linked checking, a small automatic transfer — used as the boundary checking vs savings account describes: a reserve or a dated goal you do not want a card attached to. Its rate is poor and its job is not the rate. If the balance grows into the thousands and stays there, the rate starts to cost real money, and the question becomes whether to move it into a money market account at the same bank or into an online account elsewhere; the second is the question money market vs high-yield savings answers.
The money market account fits a larger balance held for a dated, sizeable payment — a house deposit, a renovation, a tax bill, the kind of sinking fund that will be spent by cheque or card in a few large transactions — above the waiver line and, if the rate is tiered, above the breakpoint that pays the advertised figure. It fits badly below the waiver line, where the fee eats it, and badly as an everyday spending account, where the transfer limit bites.
Neither is the answer for an emergency fund at branch-bank rates. Where to keep an emergency fund covers that job — insured, reachable within a day, and paying something — and it usually means neither of the two accounts opened at the branch.
What to actually do
Read the fee and its waiver before the rate. On a balance under about $5,000 the fee decides the comparison on its own. Find the monthly charge, the balance that waives it, and the other waivers — linked checking, automatic transfers, age.
If the rate is tiered, find the method. The account disclosure must say whether the tier rate applies to the whole balance or only to the portion inside the tier. Under the second, "up to" is a figure most balances never earn on most of their money.
Verify the rate at the bank, not on this page or any table. Money market account rates is the five-minute routine; the FDIC's national figures, with the money market row printed on the hub, are the baseline to measure it against.
Count the transfer limit as a cost. Ask how many withdrawals a month are free, what the fee is above that, and whether the bank closes accounts for exceeding it. The 2020 rule removed the federal limit, not the bank's.
Add both accounts up at the same institution. They share one $250,000 limit per ownership category. Moving money between them changes nothing about coverage.
Diarise the promotional date. If a money market rate is promotional, write down the reversion date and the standard tier it reverts to, and review the account on that day.
Ask which agency. A bank's deposits are FDIC-insured; a credit union's shares are NCUA-insured. The protection is equivalent, the agency is not the same, and the disclosure names it.
