Your money sits in the bank's vault, earns interest, and stays yours to withdraw

When you deposit money into a savings account, the bank takes physical possession of it but the account remains yours. The bank uses your money to make loans to other customers and invests it in other ways—that is how banks make profit. In return, the bank pays you interest, which is a small percentage of your balance that grows over time. You can withdraw your money whenever you want, though some account types have limits on how many withdrawals you can make per month.

The money does not sit in a separate envelope with your name on it. Instead, the bank pools deposits from thousands of customers and manages that pool as a whole. Your account balance is a record of how much of that pool belongs to you. The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per account holder per bank, so even if the bank fails, you get your money back.

Key Takeaways

  • The bank lends out your money to other customers and keeps most of the interest it earns; you receive a smaller share called the deposit interest rate.
  • Interest compounds, meaning you earn interest on your interest, so your balance grows faster the longer money sits in the account.
  • Your deposits are insured by the FDIC up to $250,000 per account at each bank, protecting you if the bank fails.
  • Most savings accounts limit you to six withdrawals per month, though this rule varies by bank and account type.
  • The interest rate your bank offers changes based on what the Federal Reserve does with its benchmark rate, so your earnings may go up or down.

How the bank uses your money and pays you interest

The bank does not keep your deposit sitting idle. It lends your money to other customers as mortgages, car loans, and personal loans. Those borrowers pay the bank interest on those loans—often 5 to 8 percent or higher. The bank keeps most of that interest as profit and pays you a smaller share, called the deposit interest rate or APY (Annual Percentage Yield). A typical savings account pays between 0.01 and 5 percent APY depending on the bank and current economic conditions.

The interest you earn is calculated daily but usually paid monthly or quarterly. If your account earns 2 percent APY and you have $10,000 in the account, you earn roughly $200 per year, or about $17 per month. The exact amount depends on how many days are in the month and how the bank calculates interest—some use daily balance, others use average balance.

Compound interest means you earn interest on the interest you already earned. If you leave that $200 in the account, next year you earn 2 percent on $10,200, not just $10,000. Over decades, compound interest can roughly double your money even if you never add another dollar. This is why starting a savings account early matters, even with small deposits.

Why interest rates change and what controls them

The interest rate your bank offers is not fixed forever. It moves up and down based on what the Federal Reserve does with its benchmark interest rate, called the federal funds rate. When the Fed raises its rate, banks have to pay more to attract deposits, so savings account rates go up. When the Fed lowers its rate, banks lower what they pay you.

The Fed changes its rate roughly eight times per year based on inflation and economic conditions. If inflation is high, the Fed raises rates to cool down spending. If the economy is weak, the Fed lowers rates to encourage borrowing and spending. Your bank may change your rate within days of a Fed decision, or it may wait weeks. Some banks raise rates quickly when the Fed moves up but lower them slowly when the Fed moves down—this is normal and legal.

High-yield savings accounts, offered by online banks and some traditional banks, typically pay 4 to 5 percent APY because they have lower overhead costs than brick-and-mortar branches. Traditional banks with physical locations often pay 0.01 to 0.5 percent because they spend more on staff and buildings. Shopping around for a higher rate can earn you hundreds of dollars per year on the same balance.

Withdrawal limits and how they work

Most savings accounts limit you to six withdrawals or transfers per month. This rule comes from a Federal Reserve regulation designed to keep savings accounts separate from checking accounts, which have no withdrawal limit. If you exceed six withdrawals in a month, the bank may charge a fee (typically $10 to $35), convert your account to a checking account, or close the account.

The six-withdrawal limit applies to transfers to other accounts, not just cash withdrawals at the ATM or teller window. Transferring money from savings to your checking account counts as one withdrawal. Paying a bill from savings counts as one. However, withdrawals at an ATM owned by your bank usually do not count—only transfers out of the account do. Rules vary by bank, so check your account agreement or call your bank to confirm what counts.

Some banks have removed the six-withdrawal limit entirely, especially after the pandemic. Others still enforce it strictly. If you need to move money in and out frequently, a money market account or checking account may suit you better than a traditional savings account.

FDIC insurance and what happens if the bank fails

The FDIC insures your deposits up to $250,000 per account holder per bank. This means if your bank fails and closes, the FDIC steps in and returns your money. You do not have to do anything—the FDIC contacts you automatically. The process usually takes a few weeks, though in rare cases it can take longer.

The $250,000 limit applies per account holder per bank, not per account. If you have a savings account and a checking account at the same bank, they share the $250,000 limit. If you have $150,000 in savings and $120,000 in checking at the same bank, only $250,000 is insured and $20,000 is at risk. However, if you have accounts at two different banks, each bank's accounts are insured separately up to $250,000.

Joint accounts are insured separately. If you and your spouse both own a joint savings account with $300,000, the FDIC insures the full $300,000 because it counts as a joint account, not an individual account. Retirement accounts (IRAs, 401(k)s) are also insured separately up to $250,000 per person per bank.

Fees that reduce your interest earnings

Banks charge various fees on savings accounts that eat into your interest. The most common are monthly maintenance fees ($5 to $15), overdraft fees if you withdraw more than your balance, excess withdrawal fees if you exceed the monthly limit, and inactivity fees if you do not use the account for a long time.

A $10 monthly maintenance fee on a savings account earning $5 per month in interest means you actually lose $5 per month. Over a year, that is $60 in lost earnings. Many banks waive the monthly fee if you maintain a minimum balance (often $500 to $2,500) or set up direct deposit. Online banks typically charge no monthly fee because they have lower costs.

Before opening a savings account, read the fee schedule. A high-yield account with no monthly fee at an online bank will almost always earn you more money than a traditional bank account with fees, even if the traditional bank's stated rate looks similar.

How to move money in and out of your savings account

You can deposit money into a savings account by transferring from another account, depositing a check through mobile banking, or handing cash to a teller. Transfers from another bank usually take one to three business days. Internal transfers between your own accounts at the same bank are when ready or next-day.

You can withdraw money by transferring to another account, visiting an ATM, or asking a teller for cash. ATM withdrawals are when ready if the ATM is owned by your bank. Transfers to another bank take one to three business days. If you need cash when ready, visit a branch or use your bank's ATM.

Some savings accounts come with a debit card or ATM card, but many do not. If your account does not have a card, you can still withdraw money by transferring to a checking account and using that account's debit card, or by visiting a branch in person.

Frequently Asked Questions

Can I lose money in a savings account?

You cannot lose the principal amount you deposit because the FDIC insures it. However, if inflation is higher than your interest rate, your money loses purchasing power. If inflation is 3 percent and your account earns 1 percent, you are effectively losing 2 percent in real value each year. This is why shopping for higher rates matters during high-inflation periods.

What is the difference between a savings account and a money market account?

A money market account usually pays a higher interest rate than a savings account but requires a larger minimum balance (often $2,500 or more) and may limit withdrawals. Some money market accounts come with a debit card or checkbook, making them more like a hybrid between savings and checking. Both are FDIC insured up to $250,000.

Do I have to report savings account interest on my taxes?

Yes. Banks send you a 1099-INT form each January if you earned $10 or more in interest during the previous year. You report this interest as income on your tax return. Even if you do not receive a 1099-INT, you must report all interest earned. The amount is usually small, but the IRS tracks it.

Can the bank take money out of my savings account without permission?

A bank can only withdraw money if you authorize it, such as through a transfer you request or a bill payment you set up. If you overdraft a checking account, the bank may transfer money from your savings to cover it, but only if you have linked the accounts for overdraft protection. Check your account agreement to see if this is enabled.

What happens to my savings account if I die?

The money becomes part of your estate and goes to whoever you named as a beneficiary, or to your heirs if you did not name one. The bank will freeze the account until your estate is settled. You can avoid this by naming a beneficiary on the account—most banks let you do this for free, and the money passes directly to that person outside of probate.
