What a bank account is and why the type matters
A bank account is a record the bank keeps of your money. You deposit cash or transfers in, the bank holds it, and you withdraw it when you need it. The bank also pays you a small amount of interest on some accounts, or charges you a fee on others. The type of account you open determines three things: how you access your money, what the bank pays or charges you, and what the bank expects you to do with it.
Banks offer different account types because different people use money differently. Someone who gets paid weekly and spends it throughout the month needs something different from someone who saves for a house down payment. The type you choose affects how much it costs you, how fast you can get your money out, and whether the bank will let you write checks or use a debit card.
Key Takeaways
- A checking account is for regular spending: you can write checks, use a debit card, and set up automatic bill payments, but the bank usually pays no interest.
- A savings account earns interest on your balance but limits how many times per month you can withdraw money without a penalty.
- A money market account combines features of both—higher interest rates and check-writing ability—but requires a larger opening deposit and balance.
- A certificate of deposit (CD) locks your money away for a set time in exchange for a may provide interest rate higher than savings accounts offer.
- The right account type depends on whether you need frequent access to your money or whether you are willing to leave it untouched to earn more interest.
Checking accounts: built for everyday spending
A checking account is designed for money you use regularly. You can write paper checks, use a debit card at stores and ATMs, and set up automatic payments to pay bills. Most checking accounts charge no monthly fee if you keep a minimum balance—often $500 to $1,500, though this varies by bank—or if you receive direct deposit of your paycheck.
The trade-off is that checking accounts pay little or no interest. Your money sits there earning almost nothing. Banks do this because they use your deposits to lend to other customers and make money on those loans. In exchange, they give you the convenience of accessing your money instantly and as many times as you want.
Some checking accounts offer small interest payments if you meet conditions like maintaining a high balance or using your debit card a certain number of times per month. These are rare and the interest is still very small, but they exist. Read the account terms before you open one.
Savings accounts: for money you want to keep but might need
A savings account pays interest on your balance. The interest rate varies by bank and changes over time—right now rates are higher than they were a few years ago, but that can shift. The bank pays you because it wants to hold your money and lend it out to others.
The catch is that federal rules limit you to six withdrawals or transfers per month without paying a penalty. If you need your money more often than that, you will either pay a fee (usually $10 to $25 per extra withdrawal) or the bank will close the account. This limit exists because the bank needs to know your money will stay put long enough to lend it out reliably.
Savings accounts are best for money you are building up—an emergency fund, a vacation fund, money toward a car—but might need within a year or two. If you know you will not touch the money for years, a CD pays more interest. If you need to access it constantly, use checking.
Money market accounts: higher interest with some check-writing
A money market account is a hybrid. It pays interest higher than most savings accounts, lets you write checks or use a debit card, and still limits your withdrawals to six per month. The catch is that most banks require a larger opening deposit—often $2,500 to $10,000—and a higher minimum balance to avoid fees.
Money market accounts make sense if you have a larger amount of money sitting around, want it to earn decent interest, but also want the ability to access it without waiting. They are less common than they used to be because online banks now offer savings accounts with interest rates nearly as high, without the high minimum balance requirement.
Compare the interest rate and minimum balance requirements at several banks before opening one. A money market account at one bank might require $5,000 to open and pay 4% interest, while another requires $10,000 and pays 4.5%. The difference matters over time.
Certificates of deposit: locked-in rates for money you will not touch
A certificate of deposit, or CD, is an agreement: you give the bank a sum of money for a set period—three months, six months, one year, five years—and the bank guarantees to pay you a fixed interest rate for that entire time. When the time is up, you get your money back plus the interest.
CDs pay more interest than savings accounts because the bank knows exactly how long it can lend your money out. If you withdraw the money before the term ends, you pay a penalty—usually three to six months of interest, though it varies. This penalty is real and can be substantial, so only put money in a CD if you are certain you will not need it.
CDs are useful for money you are saving for something specific and know you will not need until a certain date—a down payment you plan to make in two years, a wedding fund for next summer. They are not useful for emergency money or money you might need sooner.
High-yield savings accounts: savings with better interest rates
A high-yield savings account is a savings account that pays significantly more interest than a traditional savings account at a brick-and-mortar bank. Most high-yield accounts are offered by online banks, which have lower overhead costs and pass the savings to you as higher interest rates.
High-yield savings accounts still have the six-withdrawal limit per month, and they still require you to keep money in them to earn interest. But the interest rate is often two to four times higher than what a traditional bank offers. Right now, high-yield savings accounts pay around 4% to 5% annual interest, while traditional savings accounts at large banks pay 0.01% to 0.05%.
The downside is that online banks have no physical branches. You cannot walk in and withdraw cash. You transfer money electronically to your checking account, then withdraw from there. This takes one to three business days. If you need cash immediately, this is not the account for you.
Money market funds versus money market accounts: do not confuse them
A money market account is a bank account. A money market fund is an investment. They have similar names but work completely differently. A money market account is FDIC-insured, meaning if the bank fails, the government protects your money up to $250,000. A money market fund is not insured. If the investment company fails or the fund loses value, you lose money.
This guide covers bank accounts, not investments. If someone offers you a "money market fund," they are selling you an investment product, not a bank account. Do not confuse the two.
Frequently Asked Questions
Can I have more than one bank account at the same time?
Yes. Many people have a checking account for bills and spending, a savings account for emergencies, and a CD for longer-term goals. You can open accounts at the same bank or different banks. Just remember that FDIC insurance covers up to $250,000 per account type per bank, so if you have two savings accounts at the same bank, the insurance covers $250,000 total across both, not $250,000 each.
What happens to my money if the bank fails?
The Federal Deposit Insurance Corporation (FDIC) insures bank accounts up to $250,000 per depositor per bank. If your bank fails, the FDIC pays you back. This protection covers checking, savings, money market accounts, and CDs. It does not cover investments like stocks or mutual funds.
Do I need a minimum balance to open an account?
Most checking and savings accounts require little or no opening deposit—sometimes as low as $1 or $25. Money market accounts usually require $2,500 to $10,000. CDs require whatever amount you want to lock away, with minimums ranging from $500 to $2,500. Check with your bank for their specific requirements.
Which account type earns the most interest?
CDs earn the most interest because your money is locked away for a set time. High-yield savings accounts come second. Regular savings accounts earn very little. Checking accounts earn almost nothing. The longer the CD term, the higher the rate is usually—a five-year CD pays more than a three-month CD.
Can I switch from one account type to another?
Yes, but it depends on the bank. Some banks let you convert a checking account to a savings account online. Others require you to close one account and open a new one. If you have a CD, you cannot convert it—you have to wait for it to mature, then open a different account with the money. Ask your bank about their conversion policy before you open an account.
