A savings account is a bank or credit union account where you deposit money, earn a small amount of interest, and can withdraw funds when you need them.

Unlike a checking account, which is built for frequent transactions, a savings account is designed to hold money you are not spending right now. The bank pays you interest — a percentage of your balance — for letting them use your money. In return, you get a safe place to store cash and watch it grow slightly over time.

Most savings accounts come with limits on how many withdrawals you can make per month (often six), though many banks have relaxed this rule. You can usually withdraw money whenever you need it without penalty, which makes a savings account different from a certificate of deposit (CD) or bond, where early withdrawal costs you.

Key Takeaways

  • A savings account earns interest on your balance, meaning the bank pays you to keep money there.
  • You can withdraw your money at any time without losing the interest you have already earned, though some accounts limit the number of withdrawals per month.
  • The interest rate varies by bank and changes over time, so comparing rates across institutions can add hundreds of dollars to your balance over a year.
  • Your deposits are insured up to $250,000 per account holder per bank through the FDIC (Federal Deposit Insurance Corporation) or NCUA (National Credit Union Administration) for credit unions.

How interest works in a savings account

The bank takes deposits from customers like you and lends that money to other customers as mortgages, car loans, and business loans. The bank keeps the difference between what it pays you in interest and what it charges borrowers. Your interest rate is expressed as an annual percentage yield (APY), which tells you how much you will earn in a year if you leave the money untouched.

Interest compounds, usually daily or monthly, which means you earn interest on your interest. If you deposit $1,000 at an APY of 4.5%, after one year you will have roughly $1,045. After two years, you earn 4.5% on $1,045, not just the original $1,000. The longer money sits in the account, the more this compounding effect adds up — though the growth is modest compared to stocks or bonds.

Interest rates change constantly. When the Federal Reserve raises its benchmark rate, banks typically raise the rates they offer on savings accounts. When the Fed cuts rates, savings account rates fall too. This means the APY you see today may be higher or lower in three months.

Where to open a savings account

You can open a savings account at a traditional bank (Chase, Bank of America, Wells Fargo), an online-only bank (Ally, Marcus, Discover), or a credit union. Online banks often pay higher interest rates because they have lower overhead costs. Traditional banks offer the advantage of physical branches where you can deposit cash or speak to someone in person.

Credit unions are member-owned cooperatives that often pay competitive rates and charge lower fees than traditional banks. To join a credit union, you usually need to meet a membership requirement — working for a certain employer, living in a specific area, or belonging to an organization. Many credit unions are part of shared branching networks, so you can conduct transactions at other credit unions' branches even if you do not bank there.

When comparing accounts, look at the APY, any monthly fees, the minimum balance required to open the account, and whether you can access your money online, by phone, or in person. Some accounts offer higher rates if you maintain a larger balance or set up direct deposit.

FDIC and NCUA insurance protects your money

When you deposit money in a savings account at an FDIC-insured bank, your balance is protected up to $250,000 per account holder per institution. This means if the bank fails, the federal government guarantees you will get your money back. Credit unions have the same protection through the NCUA (National Credit Union Administration), also up to $250,000.

The insurance covers each account separately, so if you have a savings account and a checking account at the same bank, each is insured up to $250,000. If you have accounts at two different banks, each bank's $250,000 limit applies separately. This protection does not apply to investments like stocks or mutual funds held at a brokerage, even if that brokerage is part of a bank.

Savings accounts versus other places to keep money

A savings account earns more interest than a checking account, which typically pays little to no interest. However, a high-yield savings account (offered by many online banks) pays significantly more than a traditional savings account — sometimes 4% or higher, compared to 0.01% at some brick-and-mortar banks. The trade-off is that high-yield accounts usually require you to bank online rather than visit a branch.

A money market account is a hybrid between a checking and savings account: it pays interest like a savings account but lets you write checks or use a debit card like a checking account. Money market accounts often require a higher minimum balance and may pay slightly higher interest than a regular savings account.

A certificate of deposit (CD) locks your money away for a set period — three months, one year, five years — and pays a higher interest rate than a savings account in exchange. If you withdraw before the term ends, you pay a penalty. A savings account gives you flexibility; a CD gives you a higher rate if you can afford to wait.

How to choose between savings accounts

Start by listing what matters to you: the highest possible interest rate, the ability to visit a physical branch, low or no monthly fees, or a low minimum balance to open. Then compare three to five institutions using their websites. Most banks display the current APY prominently on their savings account page.

Calculate what your money will earn over one year at each rate. The difference between a 0.01% APY and a 4.5% APY on $10,000 is roughly $450 per year — real money that adds up. Online banks almost always offer higher rates, but if you need to deposit cash frequently, a traditional bank or credit union with branches may be worth a slightly lower rate.

Once you open an account, you do not have to stay there forever. If another bank raises its rate significantly higher, you can open a new account and transfer your balance. There is no penalty for moving your money between banks.

Frequently Asked Questions

Can I lose money in a savings account?

No. Your principal — the money you deposit — is protected by FDIC or NCUA insurance and cannot go down. However, if inflation rises faster than your interest rate, your money loses purchasing power. If you earn 1% interest but inflation is 3%, your savings are effectively worth less in real terms.

How often can I withdraw money from a savings account?

Most banks allow unlimited withdrawals, though some still enforce a limit of six per month. Check your account's terms before opening. Even with limits, you can always withdraw all your money at once if you need it.

Do I pay taxes on savings account interest?

Yes. Interest earned on a savings account is taxable income. The bank will send you a 1099-INT form at the end of the year if you earned $10 or more in interest, and you report this on your tax return. The interest is taxed at your ordinary income tax rate, not a special rate.

What is the difference between APY and APR?

APY (annual percentage yield) includes the effect of compounding and shows what you actually earn. APR (annual percentage rate) does not include compounding. For savings accounts, APY is the number that matters because it reflects real earnings.

Should I keep my emergency fund in a savings account?

Yes. A savings account is ideal for emergency money because it is safe, earns interest, and lets you withdraw funds quickly without penalty. A high-yield savings account gives you the best of both worlds: your money grows and stays accessible.
