The Fidelity Cash Management Account (often shortened to Fidelity CMA) is a brokerage account that handles everyday banking: deposits, a debit card, checks and bill pay. Fidelity Investments, the Boston-based broker founded in 1946, does not offer a traditional savings account, high-yield or otherwise, and the CMA is its closest product. It pays interest on uninvested cash by moving that cash into accounts at partner banks, where it is eligible for FDIC insurance. It has no minimum deposit and no monthly fee. The yield is variable. It was 1.96% APY on November 8, 2026.

That rate is the main trade-off. The CMA works more like an interest-bearing checking account attached to an investment platform than a savings account built to chase the top yield. It suits people who value convenience, no fees and ATM reimbursement more than they value the highest rate.

What the Fidelity Cash Management Account Is

Fidelity is not a bank. It is a broker-dealer regulated by the SEC, FINRA, NYSE and SIPC. The CMA is technically a brokerage account, even though most people use it like a checking account. Fidelity offers it to customers who want basic banking features and interest on their cash in the same place they invest.

The account is built around three uses:

• Spending: debit card, checks, bill pay and transfers.
• Saving: cash earns interest through the deposit sweep.
• Investing: money in the account can be put into investments, although invested money no longer earns the sweep interest.

The CMA can be opened alongside a regular Fidelity brokerage account. That makes it easy to move cash between spending money and investments without an outside bank transfer.

Interest Rate and How It Is Paid

The CMA’s yield is a single variable rate. It is not a tiered schedule. Per the account terms, you do not need a minimum balance to earn it: any balance above zero qualifies. Fidelity can change the rate at any time, so the 1.96% APY above is a snapshot, not a guaranteed rate.

Interest works like this:

• Accrual: interest accrues daily on balances swept into the partner banks.
• Payment: Fidelity credits interest on the last business day of each month.
• Invested cash: money you move into stocks, funds or other investments does not earn the CMA sweep rate. It earns whatever that investment returns, which may be more, less or negative.

The CMA sweep rate is also separate from the yield on cash sitting in a standard Fidelity brokerage account. Those accounts hold uninvested cash in their own core position, and its yield is set separately. A quoted Fidelity CMA interest rate should not be read as the rate on idle cash in every Fidelity account.

Estimating monthly interest

Because interest compounds and is paid monthly, a reasonable estimate of one month’s interest is:

Monthly interest ≈ balance × ((1 + APY)^(1/12) − 1)

This assumes the balance and the rate stay the same for the whole month. In practice, the rate can change and daily balances move with deposits and spending, so actual payments will differ.

Key Features

ATM fee reimbursement

Fidelity reimburses ATM fees when you use the Fidelity debit card at any ATM showing the Visa, Plus or Star logo. The credit covers fees deducted from your account, and in most cases it posts the same day. This matters most for people who travel or who live where no single bank has a dense ATM network. Many online accounts reimburse only up to a monthly cap or not at all. The CMA carries no dollar cap on the reimbursement.

Withdrawals and transfer limits

There is no cap on how many withdrawals you make in a month. That separates the CMA from savings accounts that limit or discourage frequent withdrawals. The account does have dollar limits, though: the debit card has daily spending limits and electronic transfers have daily amount limits. If you plan a large one-time payment, such as a down payment or tuition, find out the applicable limit ahead of time. You may need to split the transfer over several days or use a wire.

FDIC Insurance and the Deposit Sweep Program

Because the CMA is a brokerage account, the cash is not insured simply because Fidelity holds it. Instead, Fidelity runs an FDIC-Insured Deposit Sweep Program. Uninvested cash in the CMA is placed into deposit accounts at one or more program banks, and FDIC coverage applies at each of those banks.

The standard FDIC limit is $250,000 per depositor, per FDIC-insured bank, per account ownership category. Spreading cash across several program banks lets one CMA reach total coverage well above that figure. Fidelity states coverage of up to $4 million through the program. Two conditions apply:

• Program bank capacity: the higher total depends on the program banks having room to accept your deposits.
• Your other deposits: if you already hold money directly at one of the program banks, those funds count toward the same $250,000 limit at that bank. Overlapping balances can leave part of your money uninsured.

FDIC coverage applies to the swept cash. Securities you buy inside or alongside the account are not FDIC-insured. They are subject to market risk, and the protection that applies to them is SIPC coverage of the brokerage. SIPC is not insurance against investment losses.

Examples

All three examples are hypothetical and use assumed figures to show the mechanics. They are not Fidelity’s terms or a forecast.

Example 1: Interest on a steady balance

Assume a $10,000 balance stays in the CMA all month at a hypothetical 2.00% APY.

• Monthly factor: (1.02)^(1/12) − 1 ≈ 0.001652
• Monthly interest ≈ $10,000 × 0.001652 ≈ $16.52
• Over 12 months with no rate change and interest left in the account, the APY implies about $200.

If a high-yield savings account paid a hypothetical 4.00% APY on the same balance, it would earn about $400 a year. The gap of about $200 is the price of the CMA’s ATM reimbursement, checks and direct access to investments in that scenario.

Example 2: Investing part of the balance

Assume the same $10,000, but you move $4,000 into a fund on the first of the month. Only the remaining $6,000 earns the sweep rate, so at a hypothetical 2.00% APY the month’s interest falls to about $9.91. The $4,000 now rises or falls with the fund, with no FDIC protection on that portion.

Example 3: A large cash balance

Assume someone holds $600,000 in the CMA after selling a home. A single bank account would leave $350,000 above the $250,000 FDIC limit for that ownership category. Through the sweep program, the cash is spread across several program banks so the amount at each one can stay within the limit. If this person also has $200,000 in a personal account at one of those program banks, that balance counts too, and the combined amount at that bank could exceed coverage.

Pros and Cons

Pros

• No minimum and no monthly fee: you can open and keep the account with any balance.
• Interest on every dollar: any non-zero balance earns the stated APY, with no tiers to reach.
• ATM fee reimbursement: fees at Visa, Plus or Star ATMs are credited back, usually the same day.
• Unlimited withdrawals and checks: no monthly cap on the number of withdrawals, plus free check writing and bill pay.
• Expanded FDIC coverage: the sweep program can extend coverage to as much as $4 million, subject to program bank capacity.
• Direct link to investing: cash can move into investments without an outside transfer.

Cons

• Lower yield than many savings accounts: the CMA’s rate has generally trailed top high-yield savings accounts, so cash parked for the long term may earn less here.
• Daily dollar limits: debit card spending and electronic transfers have daily caps that can slow large payments.
• Not a bank account: coverage depends on the sweep program, and overlapping deposits at program banks can reduce it.
• Variable rate: the yield can fall at any time, with no promotional or locked rate.

Fidelity CMA vs. a High-Yield Savings Account

The comparison comes down to what the cash is for.

A common setup is to keep spending money and a short buffer in the CMA and hold larger savings in a higher-yielding account. Other options with FDIC coverage include CDs (a fixed rate in exchange for locking up the money) and money market deposit accounts at banks.

Fidelity’s Other Accounts

The CMA is one of several Fidelity account types. Its other accounts include:

• Brokerage accounts (stock and ETF trades at $0 commission; options at $0.65 per contract)
• IRAs: Roth, traditional and rollover
• 529 college savings accounts
• Crypto trading through Fidelity Crypto
• Fidelity Go, its robo-advisor

Fidelity also offers mutual funds and fixed-income products such as Treasury, corporate and municipal bonds and brokered CDs, plus financial planning and wealth management through advisors. CMA customers can reach all of this from the same login.

How to Open a Fidelity Cash Management Account

1. Apply online. Most individual and joint accounts can be opened through Fidelity’s online application.
2. Add a brokerage account if you want one. You can open the CMA and a brokerage account in the same session.
3. Use the paper form for trusts. Accounts with special trust registrations require you to download, print and complete a PDF application instead of applying online.
4. Fund the account. There is no minimum deposit, so you can start with any amount.
5. Set up spending features. Order the debit card, set up bill pay and enable mobile check deposit if you plan to use the account for daily banking.

Who It May Suit

The CMA fits people who already invest with Fidelity or plan to, and want one place for spending and investing. It also fits frequent ATM users and travelers who benefit from fee reimbursement. Anyone holding large cash balances can use the expanded FDIC coverage. It is a weaker fit if your main goal is the highest yield on savings, or if you regularly move large sums in one day and could run into the daily transfer limits.

The Bottom Line

The Fidelity CMA suits Fidelity investors, frequent ATM users, travelers and people holding large cash balances who want one fee-free place to spend and invest. Its yield has generally trailed top high-yield savings accounts, so long-term savings may earn more elsewhere. A practical approach is to keep spending money and a short buffer in the CMA and hold larger savings in a higher-yielding account.
