What happens when you put money in a savings account

When you deposit money into a savings account, the bank takes that cash and lends it out to other customers — for mortgages, car loans, credit cards, and business lines of credit. In exchange for letting the bank use your money, the bank pays you interest. That interest is a percentage of your balance, added to your account on a schedule the bank sets (usually monthly or daily).

Your money stays yours. You can withdraw it whenever you want, and the bank is required by federal law to keep it safe. The bank also insures deposits up to $250,000 per account holder per bank through the FDIC (Federal Deposit Insurance Corporation), so even if the bank fails, your money is protected.

The trade-off is that savings accounts offer lower interest rates than other investments, because your money is always available to you. The bank cannot count on keeping your balance for a set period, so it pays less for the privilege of borrowing it.

Key Takeaways

  • The bank pays you interest on your savings balance in exchange for the right to lend your money to other customers.
  • You can withdraw your money at any time without penalty, though some accounts limit the number of withdrawals per month.
  • Your deposits are insured up to $250,000 per account holder per bank by the FDIC, protecting you if the bank fails.
  • Interest rates on savings accounts vary by bank and change over time, so comparing rates before opening an account matters.
  • The interest you earn is taxable income, and the bank will send you a tax form (1099-INT) if you earn $10 or more in a year.

How interest gets calculated and added to your account

The interest rate a bank offers is usually stated as an APY (Annual Percentage Yield). This is the total percentage of your balance you will earn in one year, including the effect of compounding — meaning interest earned on top of interest already earned.

Banks calculate interest daily or monthly, depending on the account. If your account compounds daily, the bank divides the annual rate by 365, applies that tiny daily rate to your balance, and adds the result to your account. The next day, interest is calculated on the new, slightly larger balance. Over a year, this compounding adds up.

For example, if you have $1,000 in an account earning 4.00% APY compounded daily, you will not earn exactly $40 in the first year. You will earn slightly more, because each day's interest gets added to the balance before the next day's interest is calculated. The exact amount depends on how many days pass and how the bank's system rounds.

Interest is typically deposited into your account monthly, though some banks do it daily or quarterly. Check your account agreement or the bank's website to see the schedule for your specific account.

Withdrawal limits and how they work

Federal rules once capped the number of withdrawals you could make from a savings account at six per month. Those rules were suspended in 2020 and have not been reinstated, so most banks now allow unlimited withdrawals. However, some banks still impose their own limits, so check your account terms before opening.

Withdrawals include transfers to other accounts (at your bank or elsewhere), checks written against the account, and ATM withdrawals. In-person withdrawals at a branch usually do not count toward a limit, if one exists.

If you exceed a withdrawal limit, the bank may charge a fee per excess withdrawal, typically $5 to $10. Some banks will simply close the account or convert it to a checking account if you repeatedly exceed the limit. Read the account agreement to see what your bank does.

Fees that reduce your interest earnings

Savings accounts come with several possible fees that eat into the interest you earn. The most common are monthly maintenance fees (usually $5 to $15), charged just for having the account open. Some banks waive this fee if you maintain a minimum balance, set up direct deposit, or meet other conditions.

Other fees include overdraft fees (charged if you withdraw more than your balance), ATM fees (if you use an out-of-network ATM), and excess withdrawal fees (if you exceed the bank's limit). Some banks also charge a fee if your balance falls below a stated minimum.

Online banks and credit unions typically charge fewer or no fees, because they have lower overhead costs than brick-and-mortar banks. If you are comparing accounts, subtract the annual fees from the interest you expect to earn to see the real return.

How to access your money

You can withdraw from a savings account in several ways. At a branch, you can withdraw cash or request a cashier's check. At an ATM, you can withdraw cash using your debit card. Online, you can transfer money to another account at the same bank or to an external account (a process that usually takes one to three business days).

You can also set up automatic transfers — for instance, moving money from checking to savings on payday each month. This is a common way to build savings without thinking about it.

Some savings accounts come with a debit card, though this is less common than it used to be. If yours does, you can use it to make purchases or withdraw cash, just like a checking account debit card. However, using a debit card for everyday purchases defeats the purpose of a savings account, which is to keep money separate and let it grow.

The difference between savings and money market accounts

A money market account is a hybrid between a savings account and a checking account. It typically offers a higher interest rate than a savings account, but comes with a debit card or checkbook so you can make purchases or write checks directly from the account.

Money market accounts also usually have higher minimum balance requirements — often $2,500 or more — and may charge higher fees if your balance drops below that minimum. The interest rate is often tiered, meaning you earn more interest on larger balances.

If you want to earn interest and also need to access your money frequently for everyday spending, a money market account might make sense. If you are trying to keep savings separate from spending money, a traditional savings account is simpler and usually has lower minimums.

Why interest rates change and how to find the best rate

Savings account interest rates move up and down based on the federal funds rate, which the Federal Reserve sets. When the Fed raises rates, banks typically raise the rates they offer on savings accounts. When the Fed lowers rates, banks lower savings rates too. This can happen several times a year.

Banks also set rates based on competition. If many banks are offering high rates, a bank may raise its rate to attract deposits. If deposits are plentiful, a bank may lower its rate. Online banks often offer higher rates than traditional banks because they have lower costs and compete aggressively for deposits.

To find the best rate, check comparison websites like Bankrate or DepositAccounts, which list current rates at hundreds of banks. Call or visit the websites of banks you are considering and note the APY, any minimum balance requirement, and any fees. The highest rate is not always the best deal if it comes with high fees or a balance requirement you cannot meet.

Frequently Asked Questions

Can I lose money in a savings account?

No. Your principal — the money you deposit — is protected by the FDIC up to $250,000 per account holder per bank. You will not earn much interest if rates are very low, but you will not lose what you put in. The only way your balance goes down is if you withdraw money or the bank charges fees that exceed your interest earnings.

What is the difference between a savings account and a checking account?

A checking account is designed for frequent, everyday transactions — you can write checks, use a debit card, and set up automatic bill payments. A savings account is designed to hold money and earn interest, with fewer withdrawal options. Checking accounts typically earn little or no interest and may have higher fees.

Do I have to pay taxes on savings account interest?

Yes. Interest earned on a savings account is taxable income. If you earn $10 or more in interest in a calendar year, the bank will send you a Form 1099-INT, which you report on your tax return. The interest is taxed at your ordinary income tax rate, not as a capital gain.

Can I have more than one savings account?

Yes. You can open multiple savings accounts at the same bank or at different banks. Each account is insured separately up to $250,000 by the FDIC, so if you have $250,000 in one account and $250,000 in another at the same bank, both are fully protected. Some people open multiple accounts to organize savings for different goals.

What happens if the bank fails?

The FDIC takes over the bank's operations and pays out insured deposits (up to $250,000 per account holder per bank) to customers. This process usually takes a few days to a few weeks. You will not lose money that is within the insurance limit, though access to your account may be temporarily disrupted.
