A checking account is also called a demand deposit account
The blank is demand deposit account, often shortened to DDA. Banks use this term because a checking account lets you withdraw your money on demand — meaning whenever you want, without advance notice or penalty. The bank cannot require you to wait or give a reason.
The word "demand" is the key. Unlike a savings account, where the bank technically has the right to require notice before you withdraw large sums, a checking account is built on the assumption that you will pull money out regularly and without restriction. That is why it is called a demand deposit — the deposit is yours to demand back at any time.
You will see "DDA" on bank statements, in account agreements, and when you call customer service. It is the official banking term for what most people just call a checking account. Some banks also use the terms transaction account or checking deposit account, but demand deposit account is the standard across the banking industry and in federal regulations.

Why banks call it a demand deposit instead of a checking account
The term "demand deposit account" comes from banking law and accounting rules, not from how customers talk about money. When a bank receives your paycheck or cash deposit, that money becomes a liability on the bank's balance sheet — the bank owes it to you. The moment you can ask for it back without waiting, it is classified as a demand deposit under federal banking regulations.
Savings accounts, money market accounts, and certificates of deposit (CDs) are not demand deposits because the bank can legally require notice or impose penalties for early withdrawal. A checking account has no such restrictions, which is why regulators and accountants use the demand deposit label. It is a precise way to describe what the account actually is under the law.
How demand deposit accounts work differently from other accounts
A demand deposit account gives you unlimited access to your money with no waiting period. You can write a check, use a debit card, make an electronic transfer, or walk into a branch and withdraw cash — all without telling the bank in advance. The bank must honor your request immediately (or within one business day for electronic transfers).
A savings account, by contrast, may limit how many withdrawals you can make per month, and the bank can theoretically require you to give notice before withdrawing large amounts. A CD locks your money away for a set term; if you withdraw early, you pay a penalty. A money market account often requires a higher minimum balance and may limit transfers. None of these are demand deposits because the bank has conditions on when and how you can access your money.
This difference matters when you are comparing accounts. If you need to access your money freely and often, a demand deposit account (checking account) is what you want. If you are saving for a goal and do not plan to touch the money for months or years, a savings account or CD may offer better interest rates because the bank knows your money will stay put.
Where you will see the term demand deposit account used
Banks use "demand deposit account" or "DDA" in formal documents, not in marketing. You will see it on your monthly statement under the account type line. It appears in the account agreement you sign when you open the account. When you call the bank's customer service line and they pull up your account, they may refer to it as a DDA.
The term also shows up in tax documents. If your employer uses direct deposit, the paperwork you fill out may ask for your "demand deposit account number" instead of just saying "checking account number." The IRS and other government agencies use the formal term in official guidance and forms.
You will also see it in banking regulations and in news articles about banking policy. When regulators talk about how much interest banks can pay on different account types, they distinguish between demand deposits and time deposits (like CDs). This distinction affects how banks operate and what they can charge you.
Interest on demand deposit accounts
Some checking accounts earn interest, and some do not. Whether or not your demand deposit account pays interest does not change what it is called — it is still a DDA. The difference is usually in the account type: a basic checking account typically earns no interest, while a high-yield checking account or interest-bearing checking account does.
Interest rates on checking accounts vary widely by bank and by how much money you keep in the account. Some banks pay almost nothing; others pay rates closer to what savings accounts offer, especially if you meet conditions like maintaining a high balance or setting up direct deposit. The trade-off is that interest-bearing checking accounts often come with monthly fees if you do not meet those conditions.
Frequently Asked Questions
Is a demand deposit account the same as a checking account?
Yes. Demand deposit account is the formal banking and legal term for what most people call a checking account. Banks use both terms interchangeably, though you will see "DDA" more often in official documents and statements.
Can a demand deposit account have a monthly fee?
Yes. Many checking accounts charge monthly maintenance fees, overdraft fees, or fees for using out-of-network ATMs. The fee does not change the account's classification as a demand deposit — it just means the bank is charging you for the service.
Do I need a demand deposit account for direct deposit?
Most employers require a checking account (demand deposit account) for direct deposit, though some will accept savings accounts. Ask your employer or payroll department if you are unsure. You will need to provide your account number and routing number either way.
What happens if I withdraw all the money from my demand deposit account?
Nothing. You can withdraw your entire balance at any time without penalty or advance notice. The bank cannot stop you or charge you extra. Once the account is empty, you can close it or leave it open with a zero balance, depending on the bank's rules.
Is a demand deposit account insured by the FDIC?
Yes. Checking accounts at banks insured by the Federal Deposit Insurance Corporation (FDIC) are covered up to $250,000 per account owner, per bank. This protection applies to all demand deposit accounts at FDIC-insured banks, regardless of the interest rate or monthly fee.
