A savings account holds your money and pays you interest on it

A savings account is a bank account where you deposit money, the bank holds it, and the bank pays you interest—a small percentage of your balance—for letting them use your funds. The money stays yours; the bank is borrowing it from you. You can withdraw what you deposited at any time, though some accounts limit how many withdrawals you can make per month without a fee.

The mechanics are straightforward: you put money in, the bank credits your account, and your balance grows both from deposits you make and from interest the bank adds. The bank uses your deposits to lend to other customers or invest in securities. In exchange, they pay you interest. The interest rate varies by bank and by account type—some accounts pay almost nothing, others pay more if you maintain a higher balance or agree to lock your money away for a set period.

Unlike a checking account, which is designed for frequent transactions, a savings account is designed to sit. You are not supposed to write checks from it or use a debit card for everyday purchases. The account exists to separate money you plan to spend soon from money you plan to keep.

Key Takeaways

  • A savings account pays you interest on your balance, which the bank calculates and deposits into your account on a schedule set by the bank—usually monthly or daily.
  • Your money is insured up to $250,000 per account holder per bank by the Federal Deposit Insurance Corporation (FDIC) if the bank fails.
  • Most savings accounts allow unlimited deposits but limit withdrawals to six per month without charging a fee, though this rule varies by bank.
  • The interest rate you earn depends on the bank's current rate, your account type, and sometimes your balance—higher balances or longer lock-in periods often earn more.
  • Interest compounds, meaning you earn interest on your interest, so the longer money sits in the account, the more it grows.

How interest gets calculated and added to your account

Banks calculate interest on a daily or monthly basis, depending on the account. The calculation is straightforward: the bank takes your balance, multiplies it by the annual interest rate, divides by the number of days in a year (or months), and adds that amount to your account. If your account earns 4% annual interest and you have $10,000 in it, the bank calculates roughly $400 per year, or about $33 per month if compounded monthly.

The key word is compound. If the bank adds interest monthly, next month's interest is calculated on your original balance plus the interest you just earned. This means your money grows faster the longer it sits. A $10,000 deposit at 4% annual interest, compounded monthly, will grow to about $10,408 after one year—not exactly $10,400—because of compounding.

Banks post interest on different schedules. Some add it daily (calculating daily but posting monthly), others monthly, and a few quarterly. The schedule matters less than the annual percentage yield (APY), which is the rate the bank advertises and which already accounts for compounding. When comparing accounts, look at the APY, not the stated interest rate.

Deposits: how money gets into your account

You move money into a savings account through several routes. The most common is a direct transfer from another account you own at the same bank—you log into online banking, select the transfer option, choose the savings account as the destination, enter the amount, and confirm. The money appears in your savings account within minutes if both accounts are at the same bank.

You can also transfer from an account at a different bank using the other bank's online system. You provide your savings account number and routing number (a nine-digit code that identifies your bank), and the other bank initiates an ACH transfer—an electronic movement of funds that usually takes one to three business days. Some banks charge a small fee for incoming transfers from outside institutions, though most do not.

Direct deposit—where an employer or government agency deposits your paycheck or benefits directly into your account—is another route. You provide your account number and routing number to the employer or agency, and they send funds on a schedule you set (weekly, biweekly, monthly). Direct deposit is free and reliable.

You can also deposit cash or checks in person at a branch, or deposit checks by photograph using the bank's mobile app. Mobile check deposit usually posts within one business day.

Withdrawals: how money leaves your account

You withdraw money from a savings account through transfers, ATM withdrawals, or in-person withdrawals at a branch. A transfer works like a deposit in reverse: you log into online banking, select the account you want to move money to, enter the amount, and confirm. If the destination account is at the same bank, the money moves within minutes. If it is at another bank, it takes one to three business days via ACH.

ATM withdrawals are when ready if you use your bank's ATM or an ATM in a shared network. You insert your debit card, enter your PIN, select the amount, and the cash comes out. Some banks charge a fee if you use an ATM outside their network; the other bank's ATM may also charge a fee. In-person withdrawals at a branch are free and when ready—you bring your ID, tell the teller the amount, and they give you cash.

Most savings accounts come with a limit on how many withdrawals you can make per month without a fee. Federal rules once capped this at six per month, but that rule was suspended in 2020 and banks now set their own limits. Some allow unlimited withdrawals; others charge a fee after six or ten per month. Check your account agreement to know your limit. Transfers between your own accounts usually do not count against this limit, but ATM and in-person withdrawals do.

How banks protect your money

The Federal Deposit Insurance Corporation (FDIC) insures deposits at member banks up to $250,000 per account holder per bank. This means if the bank fails, the FDIC will return your money up to that limit. The insurance is automatic—you do not have to sign up or pay for it. If you have more than $250,000 at one bank, the amount over $250,000 is not insured.

If you have multiple savings accounts at the same bank, the $250,000 limit applies to all of them combined. If you want to insure more than $250,000, you can open accounts at different banks—each bank's accounts are insured separately. For example, $250,000 at Bank A and $250,000 at Bank B are both fully insured.

Beyond FDIC insurance, your money is protected by the bank's security systems. Banks use encryption to protect your account information online, and they monitor accounts for fraud. If someone makes an unauthorized withdrawal, you can report it and the bank will investigate. Your liability for unauthorized transactions is limited by law—usually $50 if you report it within 60 days.

Why interest rates change and what affects your rate

Banks set their own interest rates based on the Federal Reserve's benchmark rate, which changes several times per year. When the Federal Reserve raises its rate, banks typically raise the rates they pay on savings accounts. When the Federal Reserve lowers its rate, banks lower savings rates. This is why the interest you earn on a savings account can change month to month.

Your specific rate also depends on the account type. A regular savings account might pay 0.01% while a high-yield savings account at the same bank pays 4% or more. The difference is that high-yield accounts are often offered by online banks with lower overhead costs, or by traditional banks trying to attract deposits. Some banks offer tiered rates—you earn more interest if you maintain a higher balance.

Money market accounts and certificates of deposit (CDs) are savings products that often pay higher rates than regular savings accounts. A money market account works like a savings account but may require a higher minimum balance and pay more interest. A CD locks your money away for a set period (three months, one year, five years) and pays a fixed rate; if you withdraw before the term ends, you pay a penalty.

Fees and how to avoid them

Most savings accounts charge no monthly fee, but some do. Common fees include a monthly maintenance fee (usually $5 to $10), a fee for exceeding your withdrawal limit, a fee for falling below a minimum balance, and a fee for using an out-of-network ATM. Some banks waive monthly fees if you maintain a certain balance or set up direct deposit.

To avoid fees, read your account agreement before opening the account. Know the monthly fee (if any), the minimum balance requirement, the withdrawal limit, and which ATMs are free to use. If you cannot maintain the minimum balance, choose an account with no minimum. If you think you will withdraw more than the limit, choose an account with a higher limit or no limit.

Overdraft fees are not usually charged on savings accounts—if you try to withdraw more than you have, the transaction straightforward declines. Checking accounts are where overdraft fees happen. But some banks do charge a fee if your savings account balance goes negative, so avoid that by not linking it to a checking account for overdraft protection.

Frequently Asked Questions

How often does interest get added to my savings account?

Banks calculate interest daily or monthly depending on the account, but they usually post it (actually add it to your balance) monthly. Some post quarterly. The frequency matters less than the annual percentage yield (APY), which accounts for how often interest compounds. Check your account agreement or the bank's website to see the posting schedule.

Can I lose money in a savings account?

No, you cannot lose the principal you deposit. The FDIC insures up to $250,000, and the bank cannot take your money. However, if interest rates are very low, inflation can outpace your interest earnings, meaning your money loses purchasing power over time. This is not the same as losing the money itself.

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

A money market account usually requires a higher minimum balance and pays more interest than a regular savings account. 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 keep a minimum balance in a savings account?

It depends on the account. Some accounts require a minimum balance (often $100 to $2,500) to earn interest or avoid a monthly fee. Others have no minimum. If you cannot maintain the minimum, choose an account with no minimum requirement. The bank will tell you the minimum when you open the account.

What happens if I withdraw money before a certain time period?

Regular savings accounts have no time restriction—you can withdraw whenever you want (subject to your monthly withdrawal limit). Certificates of deposit (CDs) lock your money for a set period; if you withdraw early, you pay a penalty, usually a few months of interest. Savings accounts do not have early withdrawal penalties.
