A savings account holds your money at a bank or credit union and pays you interest on the balance

When you open a savings account, you deposit money that the bank holds for you. The bank then lends that money to other customers as mortgages, car loans, and business loans. In exchange for using your money, the bank pays you interest — a percentage of your balance, calculated and added to your account on a schedule the bank sets (usually monthly or daily).

The interest rate varies by bank, by account type, and by how much money you have in the account. A bank might pay 0.01% annual interest on a basic savings account, or 4.5% or higher on a high-yield savings account. The difference between these rates means hundreds of dollars per year on a $10,000 balance, so the rate matters.

Your money is insured by the Federal Deposit Insurance Corporation (FDIC) if your bank is FDIC-insured, which most are. FDIC insurance covers up to $250,000 per account holder per bank, so if the bank fails, you do not lose your money.

Key Takeaways

  • A savings account earns interest on your balance, with rates ranging from nearly 0% to over 4% depending on the bank and account type.
  • The bank uses your deposited money to make loans to other customers and pays you a share of what it earns.
  • FDIC insurance protects your money up to $250,000 per account at each bank, even if the bank fails.
  • You can withdraw money from a savings account, but some banks limit the number of withdrawals per month without charging a fee.
  • Interest compounds over time, meaning you earn interest on your interest, so leaving money in the account longer increases your total earnings.

How interest is calculated and added to your account

Banks calculate interest using your account balance and the annual interest rate. If your account earns 4% annual interest and you have $1,000 in the account, you earn roughly $40 per year — though the exact amount depends on how often the bank compounds the interest.

Compounding means the bank adds interest to your balance, and then calculates next month's interest on the new, larger balance. If interest compounds monthly, you earn a small amount of interest on the interest itself. If it compounds daily, you earn slightly more. Over years, this difference adds up.

Most banks show you the interest rate as an Annual Percentage Yield (APY), which accounts for compounding. The APY is what you will actually earn if you leave the money untouched for a year. A bank might advertise a 4.5% APY, meaning $1,000 grows to $1,045 in one year (before any withdrawals).

Deposits, withdrawals, and transaction limits

You can deposit money into a savings account by transferring it from another account, depositing a check, or using an ATM. Withdrawals work the same way — you can transfer money out, write a check from some savings accounts, or use an ATM.

Historically, federal rules limited savings account withdrawals to six per month. Those rules changed in 2020, and most banks now allow unlimited withdrawals. However, some banks still charge a fee if you exceed a certain number of withdrawals in a month, so check your account terms. Frequent withdrawals do not affect your interest rate, but they do reduce your balance and therefore your interest earnings.

Deposits have no limit — you can add money to a savings account as often as you want.

The difference between savings accounts and checking accounts

A checking account is designed for frequent, everyday transactions. It usually comes with a debit card and checks, and you can withdraw money as many times as you want without fees. Most checking accounts earn little to no interest.

A savings account is designed to hold money you are not spending right now. It typically earns interest, but may have fewer withdrawal options or charge fees for frequent withdrawals. You usually do not get a debit card or checks with a savings account.

Many people keep both: a checking account for bills and daily spending, and a savings account for money they want to grow. Some banks offer money market accounts, which are a hybrid — they earn higher interest than savings accounts but may require a larger minimum balance.

How to choose between different types of savings accounts

Banks offer several savings account types, each with different interest rates and rules. A basic savings account has no minimum balance requirement and earns a low interest rate, often under 0.5% APY. A high-yield savings account earns significantly more — currently 4% to 5% APY at many online banks — but may require a higher minimum balance to open.

Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. If you do not need to visit a physical branch, an online savings account usually pays more interest on the same balance.

Some accounts are tied to specific purposes: a certificate of deposit (CD) locks your money away for a set period (three months to five years) and pays a higher interest rate in exchange. You pay a penalty if you withdraw before the term ends. A CD makes sense if you know you will not need the money for a specific amount of time.

What happens to your money when you are not using it

Your money sits in the bank's vault or in the bank's reserve accounts at the Federal Reserve. The bank does not keep your specific dollars in a separate box — it pools deposits from all customers and uses that pool to make loans. Your account balance is a record of how much of that pool belongs to you.

The bank pays interest from the money it earns by lending out deposits. If interest rates rise, banks raise the rates they pay on savings accounts because they can earn more from loans. If rates fall, banks lower savings rates. This is why your APY can change over time.

You always own the money in your account. You can withdraw it whenever you want (subject to any withdrawal limits your bank sets). The bank cannot use your money without your permission, and FDIC insurance protects it if the bank fails.

How inflation affects your savings account earnings

Inflation is the rate at which prices rise over time. If inflation is 3% per year and your savings account earns 2% interest, your money is actually losing buying power — you can buy less with it next year than you can today, even though the dollar amount in your account went up.

This is why the interest rate matters. When inflation is high, you need a savings account that earns at least as much as the inflation rate, or more. When inflation is low, even a 0.5% interest rate keeps your money roughly even. Currently, inflation varies by year and by what you are measuring, so compare your account's APY to recent inflation rates to understand whether your savings are keeping pace.

High-yield savings accounts are useful during high-inflation periods because they earn rates closer to inflation. Basic savings accounts with very low rates are less useful in those times.

Frequently Asked Questions

Can I lose money in a savings account?

No, the bank cannot take money from your account without your permission. FDIC insurance protects balances up to $250,000 if the bank fails. Your balance can shrink if you withdraw money or if fees are charged, but the bank cannot reduce your balance on its own.

How often does interest get added to my account?

Most banks add interest monthly or daily. Daily compounding earns slightly more than monthly compounding over a year. Your bank statement or account terms will show you the compounding frequency. You do not have to do anything — interest is added automatically.

What is the minimum balance I need to open a savings account?

It varies by bank. Many online banks and credit unions allow you to open an account with $0 or $1. Some banks require $100 or $500 to open. A few high-yield accounts require $2,500 or more. Check the specific bank's requirements before opening.

Do I pay taxes on savings account interest?

Yes. Interest earned in a savings account is taxable income. Banks send you a 1099-INT form at the end of the year if you earned $10 or more in interest, and you report that amount on your tax return. The interest is taxed at your ordinary income tax rate.

Can I have multiple savings accounts at the same bank?

Yes, and many people do — one for an emergency fund, one for a vacation, one for a down payment. Each account is insured separately up to $250,000 by the FDIC, so you can hold up to $250,000 in each account at the same bank and be fully protected.
