A bank account is a contract between you and a bank that lets you store money, make withdrawals, and receive deposits

A bank account is not one thing — it is a category that includes several different types, each with its own rules about how you can use the money, what the bank pays you, and what fees you might owe. The main types are checking accounts, savings accounts, and money market accounts. Each one serves a different purpose in how you manage cash.

When you open an account, you are giving the bank permission to hold your money and use it for their own lending. In return, the bank keeps your money safe, lets you access it when you need it, and may pay you interest — a small percentage of your balance that the bank gives you for letting them use your funds. The bank is also required by law to insure your deposits up to $250,000 per account type through the Federal Deposit Insurance Corporation (FDIC), so if the bank fails, your money is protected.

Key Takeaways

  • Checking accounts are designed for frequent deposits and withdrawals, usually with a debit card and checks, and typically pay little or no interest.
  • Savings accounts restrict how often you can withdraw money but pay higher interest rates than checking accounts in exchange for leaving your money in place.
  • Money market accounts combine features of both checking and savings accounts — they offer higher interest rates but require a larger opening deposit and limit your withdrawals.
  • All three types are FDIC-insured up to $250,000 per account type at the same bank, protecting your deposits if the bank fails.
  • The type of account you choose depends on whether you need frequent access to your money or whether you want to set funds aside and earn interest.

Checking accounts are built for everyday spending

A checking account is designed for money you use regularly. You can deposit paychecks, withdraw cash at an ATM, write checks, and use a debit card as many times as you want without penalty. Most checking accounts pay zero interest or a very small amount — often less than 0.01 percent per year — because the bank expects you to move money in and out constantly.

Checking accounts usually come with monthly fees, though many banks waive the fee if you keep a minimum balance (often $500 to $1,500) or set up direct deposit. Some banks charge per check written or per ATM withdrawal outside their network. The trade-off is convenience: you can access your money instantly whenever you need it.

Savings accounts pay interest but limit your withdrawals

A savings account is meant for money you want to keep and grow. The bank pays you interest — typically between 4 and 5 percent per year at online banks, though rates vary by bank and change over time. In exchange, federal rules historically limited you to six withdrawals per month, though many banks have removed this restriction in recent years.

Savings accounts usually have lower or no monthly fees, and the interest rate is higher than checking because the bank expects your money to stay put longer. If you need to withdraw more than the limit allows, the bank may charge a fee or close your account. Savings accounts are best for money you are building toward a goal — an emergency fund, a down payment, or a vacation — rather than money you spend from weekly.

Money market accounts combine checking and savings features

A money market account sits between checking and savings. It pays interest rates closer to savings accounts (often 4 to 5 percent per year), but it also gives you a debit card and the ability to write checks — features you normally get only with checking. The catch is that money market accounts usually require a higher opening deposit, often $2,500 to $10,000, and they still limit how many withdrawals you can make per month.

Money market accounts make sense if you have a larger sum you want to earn interest on but also need occasional access without moving the money to a different account. They are less common than checking or savings accounts, and not all banks offer them.

How interest rates and fees differ across account types

The interest rate you earn depends on the type of account and the bank you choose. Online banks typically pay higher rates than brick-and-mortar banks because they have lower overhead costs. A savings account at an online bank might pay 4.5 percent per year, while the same account at a traditional bank might pay 0.01 percent. Checking accounts almost never pay meaningful interest, regardless of where you bank.

Fees also vary widely. Some banks charge monthly maintenance fees ($5 to $15), fees for using an out-of-network ATM ($2 to $3 per transaction), overdraft fees (often $30 to $35 when you spend more than you have), or fees for falling below a minimum balance. Other banks — particularly online banks and credit unions — charge no monthly fees at all. Before opening an account, compare the interest rate, the monthly fee, and the overdraft policy.

FDIC insurance protects your money up to $250,000

All three account types — checking, savings, and money market — are covered by FDIC insurance. This means if your bank fails, the government guarantees you will get your money back, up to $250,000 per account type at the same bank. If you have $100,000 in a checking account and $100,000 in a savings account at the same bank, both are fully protected because they are different account types.

If you have more than $250,000 to store, you can open accounts at multiple banks to keep all your money insured. Credit unions offer similar protection through the National Credit Union Administration (NCUA), also up to $250,000 per account type. This protection does not depend on the interest rate the bank pays or the fees it charges — it is automatic for any account at an FDIC-insured bank.

Choosing the right account type for your situation

Start by thinking about how you use money. If you receive a paycheck and spend from that account weekly, a checking account is the right choice. If you have money left over each month that you want to set aside and grow, a savings account earns you interest. If you have a larger sum and want both interest and occasional access, a money market account may fit.

Many people use more than one account type at the same bank. You might have a checking account for bills and groceries, a savings account for an emergency fund, and a separate savings account at an online bank for a longer-term goal like a house down payment. Each account serves a different purpose, and the FDIC insures each one separately up to $250,000.

Frequently Asked Questions

Can I move money between my checking and savings account whenever I want?

Yes, you can transfer money between your own accounts at the same bank as often as you want, usually for free. The old federal limit of six savings account withdrawals per month applied only to certain types of transfers, and most banks have removed this restriction. Check your bank's rules to be sure.

What happens if I spend more money than I have in my checking account?

If you overdraw your account, the bank will cover the transaction but charge you an overdraft fee, usually $30 to $35. Some banks offer overdraft protection, which automatically transfers money from your savings account to cover the shortfall. Others let you opt out of overdraft coverage entirely, which means the transaction will be declined instead.

Do I earn interest on a checking account?

Most checking accounts pay zero interest or less than 0.01 percent per year. A few banks offer high-yield checking accounts that pay 2 to 3 percent, but these usually require a large minimum balance or frequent direct deposits. For interest, a savings account or money market account is a better choice.

Is my money safer in a savings account than a checking account?

No. Both checking and savings accounts at FDIC-insured banks are equally protected up to $250,000. The difference is how you use the money, not how safe it is. A savings account simply pays more interest because you are expected to leave the money there longer.

Can I have multiple savings accounts at the same bank?

Yes, and each one is separately insured up to $250,000. Many people open multiple savings accounts to organize money for different goals — one for emergencies, one for a vacation, one for a car. The bank will not charge you extra for having multiple accounts, though some banks may charge a monthly fee per account.
