A bank account is a record the bank keeps of your money

A bank account is an arrangement between you and a bank. You give the bank money, and the bank holds it, keeps track of how much you have, and lets you withdraw it or send it to other people. The bank also uses your money to make loans to other customers, and pays you a small amount of interest in return for letting them do that.

When you open an account, the bank assigns it a number. Every deposit, withdrawal, and transfer gets recorded under that number. Your balance is simply the total of all the money in that account at any moment. The bank sends you a statement—on paper or online—showing every transaction and your current balance.

You access your money through a debit card, checks, online transfers, or by walking into a branch and asking for cash. The bank is responsible for keeping your money safe and following rules about how they handle it. If the bank fails, the Federal Deposit Insurance Corporation (FDIC) insures up to $250,000 of your money in each account type at that bank.

Key Takeaways

  • A bank account is a contract where you deposit money and the bank holds it, tracks it, and lets you withdraw or transfer it.
  • Every transaction—deposit, withdrawal, transfer—is recorded and appears on your statement, which shows your current balance.
  • You can access your money through a debit card, checks, online banking, or in person at a branch.
  • The FDIC insures up to $250,000 per account type per bank if the bank fails, protecting your deposits.
  • Banks pay you interest on savings accounts and charge you fees for certain services, depending on the account type and the bank's terms.

The two main types: checking and savings

A checking account is designed for frequent deposits and withdrawals. You can write checks, use a debit card, set up automatic bill payments, and transfer money online as often as you want. Most checking accounts pay little or no interest. Some banks charge a monthly fee if you don't keep a minimum balance or don't set up direct deposit.

A savings account is designed to hold money you are not spending right now. Withdrawals are usually limited—some banks allow only a few per month without charging a fee, though this rule has loosened in recent years. Savings accounts pay interest, meaning the bank pays you a percentage of your balance each month or year. The interest rate varies by bank and changes over time.

Many people have both: a checking account for bills and daily spending, and a savings account for money set aside for emergencies or goals. Some banks offer other account types, like money market accounts (which pay higher interest but require a larger minimum balance) or certificates of deposit (CDs), which lock your money away for a set time in exchange for a may provide interest rate.

How deposits and withdrawals work

A deposit is money you put into your account. You can deposit cash at a branch, at an ATM, or by mailing a check to the bank. If you receive a paycheck, your employer can deposit it directly into your account through direct deposit—the employer sends the money electronically, and it appears in your account within one or two business days. You can also transfer money from another bank account you own.

A withdrawal is money you take out. You can withdraw cash from an ATM, at a branch, or by writing a check. When you use a debit card to buy something, that is also a withdrawal—the money leaves your account and goes to the store. Online transfers and bill payments are withdrawals too. Most withdrawals happen immediately or within one business day.

The bank keeps a running total of your balance. If you withdraw more money than you have, your account goes negative. Most banks will either decline the transaction or charge you an overdraft fee (usually $25 to $35 per transaction). Some banks offer overdraft protection, which links your checking account to a savings account or credit line so the bank can cover the shortfall automatically.

Interest, fees, and how banks make money

Banks make money partly by charging you fees. A monthly maintenance fee is common at some banks if you don't meet their requirements (such as keeping a minimum balance or setting up direct deposit). Overdraft fees are charged when you spend more than you have. ATM fees may apply if you use an ATM that does not belong to your bank. Wire transfer fees apply when you send money to another bank. Read your bank's fee schedule before opening an account—fees vary widely.

Banks also make money by lending out the money you deposit. When you keep money in a savings account, the bank pays you interest—a percentage of your balance. Interest rates on savings accounts are very low right now (often less than 1% per year), but they change based on what the Federal Reserve does. Some banks pay higher interest rates on savings accounts than others, so it is worth comparing.

Checking accounts usually pay no interest. Some banks offer checking accounts that pay a small amount of interest if you meet certain conditions, like setting up direct deposit or maintaining a high balance, but these are less common.

How the bank protects your money

Banks are required by law to keep your money separate from their own money and to follow strict rules about how they handle deposits. If you deposit $5,000, that $5,000 belongs to you, not the bank. The bank can use it to make loans, but they must have enough money on hand to pay you back if you ask for it.

The FDIC is a government agency that insures bank deposits. If your bank fails and closes, the FDIC will pay you back up to $250,000 for each account type you have at that bank. So if you have a checking account with $100,000 and a savings account with $100,000 at the same bank, both are covered. If you have $300,000 in one savings account, only $250,000 is insured. Most banks display the FDIC logo on their website and in their branches.

Your bank account is also protected against fraud. If someone steals your debit card or hacks your online banking password and makes unauthorized transactions, federal law limits your liability. If you report the fraud within two business days, you are responsible for no more than $50 of the loss. If you wait longer, your liability can be higher, but most banks cover unauthorized transactions anyway as a customer service.

How to open and manage an account

To open a bank account, you go to a bank branch or visit their website. You will need to provide your name, address, date of birth, and Social Security number. The bank will run a background check using a system called ChexSystems, which tracks banking history. If you have unpaid overdrafts or fraud at another bank, you may be denied, but many banks offer second-chance accounts for people with banking problems.

Once your account is open, you can manage it online, through a mobile app, by phone, or in person. Online banking lets you check your balance, transfer money, pay bills, and download statements anytime. Most banks offer free online banking. You can also set up alerts so the bank texts or emails you when your balance drops below a certain amount or when a large transaction occurs.

Keep your login information private and change your password regularly. Do not share your PIN (the number you use at ATMs) with anyone. Review your statement each month to catch errors or fraud early. If you see a transaction you did not make, contact your bank right away.

What happens when you close an account

You can close a bank account anytime by contacting your bank. You can do this online, by phone, or in person. Before you close, make sure you have withdrawn all your money or transferred it to another account. If you have outstanding checks or automatic payments set up, cancel them first or they may bounce.

If your account has a negative balance when you close it, you owe the bank that money. The bank may send it to a collection agency if you do not pay. If you close an account and later receive a check or direct deposit meant for that account, it will be rejected, so update your direct deposit information with your employer or whoever sends you money.

Some banks charge a fee to close an account if you close it within a certain time frame (often 90 days to a year). Check your account agreement to see if this applies to you.

Frequently Asked Questions

Can I have more than one bank account?

Yes. You can have multiple accounts at the same bank and at different banks. Each account is insured separately by the FDIC up to $250,000, so if you have $300,000 in savings, you could split it between two banks to protect all of it. Many people have accounts at multiple banks for different purposes or to get better interest rates.

What is the difference between a debit card and a credit card?

A debit card takes money directly from your bank account when you use it. A credit card borrows money from the credit card company, and you pay them back later. Debit cards do not build credit history, but credit cards do. With a debit card, you can only spend money you have; with a credit card, you can spend up to your credit limit and pay interest on the balance.

Why does it take two business days for money to show up?

Banks process transactions in batches at set times each day, not instantly. A deposit you make on Friday afternoon may not appear until Monday. Transfers between banks can take one to three business days because the banks have to coordinate through a clearing system. Transfers within the same bank are usually faster.

What if I forget my password or lose my debit card?

Call your bank or use their website to reset your password or report your card lost. The bank will cancel the old card and mail you a new one, usually within five to seven business days. You can request a rush card for a fee. Until the new card arrives, you can still access your money through online banking, ATMs, or by visiting a branch.

Do I need a bank account to receive a paycheck?

No, but it is the easiest way. If you do not have a bank account, your employer can issue a paper check, which you can cash at a check-cashing service (though they charge a fee). Some employers also offer payroll cards, which work like debit cards but are loaded with your paycheck. A bank account is usually cheaper and safer than these alternatives.
