A bank account is where you store money and move it in and out

A bank account is a contract between you and a bank. You give the bank your money; the bank holds it, keeps track of how much you have, and lets you take it out or send it to someone else. The bank also uses your money to make loans to other people and businesses, and pays you a small amount of interest in return for letting them do that. You can open an account at a bank, a credit union, or an online-only bank.

The money in your account is yours. The bank cannot spend it, freeze it without a court order, or close your account without telling you first. If the bank fails, the Federal Deposit Insurance Corporation (FDIC) insures up to $250,000 of your money per account type per bank. Credit unions are insured the same way through the National Credit Union Administration (NCUA).

You access your money through a debit card, checks, transfers, or by walking into a branch and asking for cash. The bank charges you fees for some of these services—overdraft fees, monthly maintenance fees, ATM fees—though many banks waive fees if you keep a minimum balance or set up direct deposit.

Key Takeaways

  • A bank account holds your money and lets you move it in and out through cards, checks, transfers, or cash withdrawal.
  • The FDIC insures up to $250,000 per account type per bank if the bank fails, so your money is protected even if the institution closes.
  • Banks charge fees for overdrafts, monthly maintenance, and ATM use, but many waive these fees if you meet certain conditions like direct deposit or a minimum balance.
  • Different account types—checking, savings, money market—serve different purposes and come with different rules about how often you can withdraw.

Checking accounts are for money you use regularly

A checking account is designed for frequent deposits and withdrawals. You can use a debit card to spend money, write checks to pay bills, and set up automatic transfers to pay recurring expenses. Most checking accounts come with no limit on how many times you can withdraw or transfer money per month.

Checking accounts typically pay little or no interest. Some banks offer interest-bearing checking accounts, but the rate is usually under 0.5 percent per year. The trade-off is convenience: you can access your money instantly without penalty.

Most checking accounts charge a monthly maintenance fee, though many banks waive it if you keep a minimum balance (often $500 to $1,500), set up direct deposit, or maintain a certain number of debit card transactions per month. If you overdraw—spend more than you have—the bank charges an overdraft fee, usually $25 to $35 per transaction, though some banks now offer overdraft protection that links your checking account to a savings account and transfers money automatically instead of charging a fee.

Savings accounts are for money you want to keep separate

A savings account is meant to hold money you are not spending right now. Savings accounts pay interest—the rate varies by bank and changes with the Federal Reserve's interest rate, but as of 2024 ranges from under 0.01 percent at traditional banks to over 4 percent at online banks. The higher rate is why many people keep emergency funds in a high-yield savings account rather than a checking account.

Savings accounts come with a withdrawal limit. Federal rules once capped withdrawals at six per month, but that rule was suspended in 2020 and has not been reinstated. However, individual banks may still limit withdrawals or charge a fee if you exceed a certain number per month—check your bank's terms. Most savings accounts charge no monthly fee, or waive the fee if you keep a minimum balance.

Savings accounts are separate from checking accounts, so money in savings does not show up on your debit card. You move money between them through a transfer, which usually takes one business day. This separation makes it harder to spend savings by accident.

Money market accounts combine features of checking and savings

A money market account pays interest like a savings account but lets you write checks and use a debit card like a checking account. The interest rate is usually higher than a checking account but lower than a high-yield savings account. The catch is that money market accounts often require a higher minimum balance—sometimes $2,500 or more—and may charge higher fees if you fall below it.

Money market accounts also come with withdrawal limits, usually three to six per month. If you exceed the limit, the bank charges a fee or converts the account to a checking account. Because of these restrictions, money market accounts are most useful if you have a large balance you want to earn interest on but also need occasional check-writing access.

How deposits and withdrawals actually move

When you deposit money, it enters your account through one of several channels. A direct deposit from your employer or government benefit goes straight into your account and is usually available the same day or next business day. A check you deposit goes to the bank's processing center, where it is scanned and sent to the bank that issued the check. That bank then transfers the money to your bank. This process, called check clearing, takes one to three business days depending on the banks involved.

When you withdraw money, it leaves your account immediately if you use an ATM or debit card. If you write a check, the money does not leave your account until the person who receives the check deposits it and it clears—which can take days. This is why you can write a check before you have the money, as long as the money arrives before the check clears. If it does not, the check bounces and you are charged a fee by both your bank and the recipient's bank.

Transfers between your own accounts at the same bank are instant or next-day. Transfers to another person's account at a different bank take one to three business days through the Automated Clearing House (ACH) network, which is the system banks use to move money between institutions. Wire transfers are faster—usually same-day or next-day—but cost $15 to $50 and are harder to reverse if you make a mistake.

Overdrafts and what happens when you spend more than you have

An overdraft occurs when you spend more money than is in your account. If your bank allows it, the transaction goes through and your balance goes negative. The bank then charges you an overdraft fee, typically $25 to $35 per transaction. If you stay overdrawn for several days, some banks charge a daily fee as well.

Not all banks allow overdrafts. Some simply decline the transaction—your debit card is rejected, your check bounces, or your transfer fails. This is safer than overdrafting because you avoid fees, but it can be embarrassing or disruptive if you are trying to pay a bill.

You can prevent overdrafts by setting up overdraft protection, which links your checking account to a savings account or credit line. If you overdraw, the bank automatically transfers money from the linked account instead of charging a fee. Some banks offer this for free; others charge a small fee per transfer, usually $1 to $3, which is much cheaper than an overdraft fee.

Fees, minimums, and how to avoid them

Banks make money partly from fees. The most common are monthly maintenance fees ($5 to $15), overdraft fees ($25 to $35), ATM fees ($2 to $3 if you use another bank's ATM), and foreign transaction fees (1 to 3 percent if you use your debit card abroad). Some banks also charge fees for paper statements, wire transfers, or closing an account early.

You can avoid most fees by choosing the right account for your situation. If you want to avoid monthly fees, look for a bank that waives them with direct deposit, a minimum balance of $500 or less, or a certain number of debit card transactions per month. If you want to avoid ATM fees, use your bank's ATM network or choose a bank that reimburses ATM fees at other banks—some online banks do this. If you travel internationally, look for a bank that does not charge foreign transaction fees.

Read the fee schedule before you open an account. Banks are required to give you a document called the Truth in Savings Act disclosure, which lists all fees and terms. Compare this document across banks, not just the advertised interest rate.

Frequently Asked Questions

What happens to my money if the bank fails?

The FDIC insures up to $250,000 per account type per bank. If your bank fails, the FDIC pays you the full amount of your insured deposits, usually within a few business days. If you have more than $250,000, only the first $250,000 is protected. To protect more money, open accounts at different banks or in different account types (checking, savings, money market) at the same bank, as each type is insured separately.

Can I have multiple accounts at the same bank?

Yes. You can have a checking account, a savings account, and a money market account all at the same bank. Each account type is insured separately up to $250,000 by the FDIC, so if you have $250,000 in checking and $250,000 in savings at the same bank, both are fully protected. However, multiple accounts of the same type at the same bank are counted together for insurance purposes.

How do I know if a bank is safe?

Check whether the bank is FDIC-insured (for banks) or NCUA-insured (for credit unions). This information is displayed on the bank's website and in the Truth in Savings disclosure. You can also search the FDIC's Bank Find tool or the NCUA's Credit Union Locator to confirm a bank's insurance status. If a bank is not insured, your money is not protected if the bank fails.

What is the difference between a bank and a credit union?

A bank is a for-profit business owned by shareholders. A credit union is a nonprofit owned by its members. Credit unions often charge lower fees and pay higher interest rates on savings, but may have fewer branches and ATMs. Both are insured the same way—up to $250,000 per account type—and both offer checking and savings accounts.

Can a bank close my account without permission?

Yes, but the bank must give you notice, usually 30 days. Banks close accounts for reasons like repeated overdrafts, suspected fraud, or violation of the account agreement. If your account is closed, the bank must return your money. If you have a pattern of overdrafts or bounced checks, some banks may close your account and report you to ChexSystems, a database that other banks use to screen applicants.
