How money moves in and out of a savings account

A savings account is a bank or credit union account where you deposit money and the institution holds it for you. You can add money whenever you want by transferring it from another account, depositing a check, or handing cash to a teller. You can withdraw money the same ways — by transfer, ATM, or in person — though some accounts limit how many withdrawals you can make each month without a fee.

The money you deposit is yours to keep. The bank does not take a cut of what you put in, and you can remove it all at any time. What changes is how much interest the bank pays you for letting them use your money while it sits there.

Key Takeaways

  • You deposit money into a savings account, and the bank holds it and pays you interest on the balance.
  • Interest rates vary by bank and change over time, so the amount you earn each month depends on the current rate and your account balance.
  • The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per account holder per bank, so your money is protected if the bank fails.
  • Most savings accounts charge no monthly fee, but some charge a fee if your balance drops below a minimum or if you exceed a withdrawal limit.
  • You can move money between a savings account and a checking account at the same bank instantly, or transfer to another bank in one to three business days.

How interest is calculated and paid

The bank pays you interest as a percentage of your account balance. This percentage is called the annual percentage yield (APY). If your account has an APY of 4.50% and you keep $10,000 in it for a full year with no deposits or withdrawals, the bank will pay you roughly $450 in interest over that year.

Interest is usually calculated daily but paid monthly. That means the bank looks at your balance every day, adds up those daily balances, and divides by the number of days in the month to find your average balance. It then applies the APY to that average and deposits the interest into your account. If you withdraw money mid-month, your interest payment shrinks because your average balance was lower.

APY rates change. Banks raise them when the Federal Reserve raises its benchmark rate and lower them when the Fed cuts rates. A savings account that paid 4.50% one month might pay 4.25% the next. You will see the new rate in your account statements and online, and it takes effect on your next interest payment.

What happens to your money when you are not using it

Your money stays in the account under your name. The bank uses deposits from all its customers to make loans — mortgages, auto loans, business loans — and keeps the difference between what it pays you in interest and what it charges borrowers. That is how banks make money.

Your specific dollars do not sit in a vault with your name on them. The bank pools all deposits and lends them out. But you have a legal claim to your balance, and you can withdraw it whenever you want. The bank must have enough cash on hand to pay you when you ask, and if it does not, the Federal Deposit Insurance Corporation (FDIC) — a government agency — covers your deposit up to $250,000.

Fees and when they apply

Most savings accounts charge no monthly maintenance fee. Some banks charge a fee only if your balance falls below a minimum — often $500 or $1,000 — or if you exceed a certain number of withdrawals per month. A few charge a small fee for each transfer to another bank.

Read the account terms before you open one. The fee schedule is usually listed under "Fees" or "Account Terms" on the bank's website. If a fee applies and you want to avoid it, you can keep your balance above the minimum or limit your withdrawals to the allowed number per month.

How to move money in and out

Deposits are fast. If you deposit cash or a check in person at a branch, it usually shows up in your account the same day or the next business day. If you transfer money from another account at the same bank, it is instant. If you transfer from a different bank, it takes one to three business days.

Withdrawals are equally straightforward. You can use an ATM to withdraw cash, transfer money to a checking account or another bank, or ask a teller to give you cash. ATM withdrawals show up immediately. Transfers to another bank take one to three business days. Some banks limit how many withdrawals you can make per month — often five or six — before charging a fee, though this rule is less common now than it was before 2020.

Why a savings account is different from a checking account

A checking account is designed for frequent spending. You get a debit card and checks, and you can withdraw money as many times as you want with no limit. A savings account is designed for money you want to keep and grow. It usually has no debit card, fewer withdrawal options, and sometimes a limit on how many times per month you can withdraw.

In return, a savings account pays interest and usually charges no monthly fee. A checking account rarely pays interest and often charges a monthly fee unless you meet a minimum balance or set up direct deposit. Many people keep both: a checking account for bills and daily spending, and a savings account for money they want to set aside.

FDIC insurance and what it covers

The FDIC insures deposits at member banks up to $250,000 per depositor per bank. That means if the bank fails, the FDIC will pay you back up to $250,000 of your balance. If you have $300,000 in one account at one bank, the FDIC covers $250,000 and you lose the rest.

If you have multiple accounts at the same bank — a savings account and a checking account, for example — they are insured separately up to $250,000 each. If you have accounts at two different banks, each bank's deposits are insured separately. The FDIC website has a calculator that shows you exactly how much of your money is covered based on how you hold your accounts.

Nearly all banks are FDIC members. Credit unions are insured by a similar agency called the National Credit Union Administration (NCUA), which covers up to $250,000 per member per credit union. Before you open an account, check the bank's or credit union's website to confirm it is insured.

Frequently Asked Questions

Can I lose money in a savings account?

No. Your balance will not go down unless you withdraw money or the bank charges a fee. Interest only adds to your balance; it never subtracts. If the bank fails, the FDIC or NCUA covers your deposit up to $250,000, so you will not lose money that way either.

How often is interest paid?

Most banks pay interest monthly, though some pay quarterly or daily. Check your account terms to see when your bank deposits interest. Even if interest is calculated daily, you will not see it in your account until the bank actually deposits it — usually the last day of the month.

What if I need to withdraw money before the month ends?

You can withdraw money anytime without penalty. Your interest payment for that month will be smaller because your average balance was lower, but you will not be charged a fee for the withdrawal itself — unless you exceed your bank's monthly withdrawal limit, which is rare now.

Do I have to keep a minimum balance?

It depends on the account. Some banks require a minimum balance of $500 or $1,000 to avoid a monthly fee. Others have no minimum. Read the account terms before you open one, or call the bank and ask what the minimum is.

Can I use a savings account like a checking account?

Technically yes, but it is not designed for it. You can withdraw money, but you will not have a debit card or checks, and some banks limit how many withdrawals you can make per month. If you need to spend money frequently, a checking account is the better choice.
