A bank account is a record the bank keeps of your money
When you open a bank account, you give the bank permission to hold your money and keep track of how much you have. The bank records every deposit you make (money going in), every withdrawal you make (money going out), and any fees or interest they add. That record is your account.
Think of it like a notebook the bank maintains on your behalf. Instead of keeping cash under your mattress, you give it to the bank. They promise to give it back whenever you ask for it, and they show you the balance — the amount you currently have — whenever you check.
The bank uses your money while they hold it. They lend it to other customers and charge them interest. In return, some accounts pay you a small amount of interest on your balance. Other accounts charge you a monthly fee for the service. Most accounts do both: they pay interest and charge fees, though the interest is usually smaller than the fee.
Key Takeaways
- A bank account is a record of your money held by a bank, showing deposits, withdrawals, and your current balance.
- The two main types are checking accounts (for everyday spending) and savings accounts (for money you want to keep).
- You need a government-issued ID and proof of address to open an account at most banks.
- Banks charge monthly fees or pay interest depending on the account type and how much money you keep in it.
- You can access your account through a debit card, checks, online transfers, or by visiting a branch in person.
Checking accounts are for money you spend regularly
A checking account is designed for everyday transactions. You deposit your paycheck, pay bills, buy groceries, and withdraw cash. The bank gives you a debit card (a plastic card that works like a credit card but pulls money directly from your account) and a checkbook (blank checks you can write to pay people or businesses).
Checking accounts usually have no interest — the bank does not pay you to keep money there. Instead, many charge a monthly maintenance fee, often between $5 and $15. Some banks waive the fee if you keep a minimum balance (usually $500 to $1,500) or set up direct deposit from your employer.
You can make as many withdrawals and transfers as you want from a checking account. There is no penalty for spending the money. This makes it the right account for bills, groceries, and everyday costs.
Savings accounts are for money you want to keep
A savings account is designed to hold money you are not spending right now. The bank pays you interest on the balance — a percentage of your money that they add to your account regularly, usually monthly or daily. The interest rate varies by bank and changes over time, but it is typically less than 1 percent per year.
Savings accounts usually have no monthly fee. However, federal rules limit you to six withdrawals per month. If you exceed that, the bank charges a fee for each extra withdrawal. This limit exists to encourage you to leave the money alone and let the interest add up.
Some savings accounts require a minimum balance to earn interest — often $100 to $500. If your balance drops below that, the interest stops. Read the account terms before you open one to understand what the bank requires.
What you need to open an account
Most banks require two pieces of information: a government-issued photo ID and proof of your address. A driver's license or passport works for ID. For proof of address, bring a recent utility bill, lease, or bank statement with your name and current address on it.
Some banks also ask for a Social Security number or an Individual Taxpayer Identification Number (ITIN). If you do not have either, ask the bank whether they offer accounts for people without a Social Security number — some do, though the process may take longer.
You will need to decide how much money to deposit to open the account. Most banks require a minimum opening deposit, often $25 to $100. Some banks have no minimum. Ask before you go in so you know what to bring.
How to access your money
Once your account is open, you can get your money in several ways. A debit card lets you buy things at stores and withdraw cash from ATMs (automated teller machines — machines that dispense cash 24 hours a day). Writing a check lets you pay bills or give money to someone without carrying cash. Online transfers let you move money to another person's account or to another bank.
You can also visit a bank branch in person and ask a teller to withdraw cash or deposit a check. This is slower than using a debit card or ATM, but it is an option if you prefer to speak to someone.
Most banks let you check your balance online or through a phone app. You can see every transaction — every deposit, withdrawal, and fee — and know exactly how much money you have at any moment.
Fees and how to avoid them
Banks charge fees for several reasons. A monthly maintenance fee is charged just for having the account. An overdraft fee is charged if you try to spend more money than you have in the account — the bank covers the difference but charges you $25 to $35 for doing so. An ATM fee is charged if you use an ATM that does not belong to your bank.
To avoid these fees, choose a bank with no monthly maintenance fee or one that waives it if you keep a minimum balance. Use only ATMs owned by your bank or by the ATM network your bank belongs to. Never spend more money than you have in your account — keep track of your balance so you do not overdraft.
Some banks offer accounts specifically designed to have no fees. These accounts may have a lower interest rate or require you to use direct deposit, but they eliminate the monthly charge. If you are on a tight budget, these accounts are worth looking for.
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 organization owned by its members — the people who have accounts there. Both hold your money and offer checking and savings accounts, but they operate differently.
Credit unions often charge lower fees and pay higher interest rates on savings accounts because they do not need to make a profit. However, credit unions have fewer branches and ATMs than large banks, so you may have less convenient access to your money. Banks have more locations but often charge more in fees.
To join a credit union, you usually have to meet a membership requirement — for example, working for a certain employer or living in a certain area. Banks are open to anyone. Both are equally safe: the federal government insures deposits up to $250,000 at both banks and credit unions, so your money is protected if the institution fails.
Frequently Asked Questions
What happens if I lose my debit card?
Call your bank when ready and tell them your card is lost. They will cancel it so no one else can use it. They will send you a new card in the mail, usually within 5 to 10 business days. Until it arrives, you can withdraw cash at a branch or use online transfers to pay bills.
Can I have more than one account at the same bank?
Yes. Many people have one checking account for everyday spending and one savings account for emergencies. You can open as many accounts as you want at the same bank. Each account has its own balance and its own debit card or checkbook.
What is a minimum balance and why does it matter?
A minimum balance is the lowest amount of money the bank requires you to keep in the account. If your balance drops below it, the bank charges a fee or stops paying interest. For example, if your savings account requires a $500 minimum and you have $400, you will lose the interest that month.
How long does it take to open an account?
At a bank branch, opening an account takes 15 to 30 minutes. Online, it can take as little as 5 minutes, though the bank may mail you a debit card that takes 5 to 10 business days to arrive. You can usually start using the account online before the card arrives.
Is my money safe in a bank account?
Yes. The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 at banks, and the National Credit Union Administration (NCUA) insures deposits up to $250,000 at credit unions. If the bank fails, the government returns your money. This protection is automatic — you do not have to do anything.
