What happens when you put money into 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, calculated and added to your account on a schedule the bank sets (usually monthly or daily, depending on the account).

You own the money the entire time. You can withdraw it whenever you want, and the bank is required by law to give it back to you. The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per person per bank, so even if the bank fails, your money is protected.

The interest rate the bank offers you varies. It depends on how much money you have, what the Federal Reserve's interest rates are doing, and how much competition that bank faces from other banks in your area. When the Fed raises rates, banks typically raise the rates they offer on savings accounts. When the Fed lowers rates, banks do the same.

Key Takeaways

  • A savings account holds your money safely while the bank pays you interest for letting them lend it out to other customers.
  • You can withdraw your money at any time, and the FDIC insures up to $250,000 per person per bank if the bank fails.
  • Interest rates on savings accounts change based on what the Federal Reserve does and how much competition your bank faces.
  • The bank calculates and adds interest to your account on a schedule — usually monthly or daily — depending on the account type.
  • Some savings accounts have limits on how many withdrawals you can make per month without paying a fee.

How interest gets calculated and added to your account

Banks calculate interest using your annual percentage yield (APY). This is the percentage rate the bank advertises, and it already accounts for how often the bank compounds your interest (adds earned interest back into your balance so you earn interest on that interest too).

The bank divides the APY by the number of days in a year, then multiplies that daily rate by your balance each day. At the end of the month (or quarter, or year — depending on the account), the bank adds all those daily interest amounts together and deposits the total into your account. The next period, you earn interest on your original balance plus the interest you just earned.

A higher APY means more money in your account over time. A savings account offering 4.5% APY will earn you more than one offering 0.01% APY, even if the balance is the same. This is why shopping around for a savings account with a competitive rate matters.

Why some savings accounts have withdrawal limits

Federal rules once capped how many times per month you could withdraw money from a savings account without paying a fee — the limit was six withdrawals. That rule changed in 2020, and now banks set their own limits. Some banks removed limits entirely. Others kept them, or set different limits for different account types.

Banks impose these limits because they want to encourage you to keep money in the account earning interest rather than moving it around constantly. If you exceed the limit, the bank charges a fee — typically $5 to $35 per excess withdrawal, depending on the bank and the account.

Before you open a savings account, check the bank's website or call and ask: "Are there limits on how many times I can withdraw money per month?" If you plan to move money in and out frequently, look for an account with no withdrawal limits, or consider a checking account instead.

The difference between savings accounts and checking accounts

A checking account is designed for money you use regularly — paying bills, buying groceries, getting cash from an ATM. Most checking accounts pay little or no interest, but they come with a debit card and checks so you can access your money easily and often.

A savings account is designed for money you want to keep and grow. It pays interest, but it typically has fewer ways to access the money (no debit card, no checks). Some savings accounts limit how many times you can withdraw per month.

Many people have both: a checking account for everyday spending and a savings account for money they want to set aside. Money in the savings account earns interest while sitting there, and you can transfer it to checking when you need it.

Fees that can reduce your savings account balance

Even though savings accounts are designed to grow your money, fees can work against that goal. Common fees include monthly maintenance fees (charged just for having the account open), excess withdrawal fees (if you withdraw more than the limit), and overdraft fees (if you somehow withdraw more than your balance — though this is rare on savings accounts).

Some banks waive monthly fees if you keep a minimum balance in the account, make direct deposits, or maintain accounts with them. Others charge the fee no matter what. Before opening an account, ask the bank: "What fees does this account have, and how can I avoid them?"

A high-yield savings account typically has no monthly maintenance fee and pays a much higher interest rate than a traditional savings account. The tradeoff is that you usually cannot access the money as quickly — transfers to other banks can take one to three business days instead of being instant.

How to move money in and out of your savings account

You can deposit money into a savings account in several ways: in person at a branch, through an ATM, by mailing a check, or by setting up a direct deposit from your employer. When you deposit cash or a check in person, the money usually shows up in your account immediately (though the bank may hold a check for a few business days before the funds are fully available).

To withdraw money, you can visit a branch and ask the teller to withdraw cash, use an ATM if the bank has one, or transfer money electronically to another account you own (like a checking account at the same bank or a different bank). Electronic transfers between banks typically take one to three business days.

Some banks also offer a savings account linked to a debit card, which lets you withdraw money more like you would from a checking account. These accounts may have higher fees or lower interest rates because of the added convenience.

What happens if you close your savings account

If you decide you no longer want the account, you can close it by visiting a branch, calling the bank, or sometimes doing it online. The bank will ask you how you want to receive any remaining balance — by check, direct deposit to another account, or cash in person.

Before you close the account, make sure you have withdrawn or transferred all your money. Some banks charge a fee for closing an account within a certain time period (often 90 days to a year after opening), so check the account terms first.

If you had earned interest that has not yet been deposited, the bank will include that in your final balance. Once the account is closed, you cannot deposit or withdraw money from it anymore.

Frequently Asked Questions

Can I have more than one savings account?

Yes. You can have multiple savings accounts at the same bank or at different banks. Some people open separate accounts for different goals — one for an emergency fund, one for a vacation, one for a down payment. Each account earns its own interest. Remember that FDIC insurance covers up to $250,000 per person per bank, so if you have more than that across multiple accounts at one bank, the excess is not insured.

What if I need my money before the interest is added?

You can withdraw your money anytime without penalty (as long as you do not exceed withdrawal limits). The interest you have earned up to that point will be included in your withdrawal. Interest that has not yet been calculated will not be paid to you.

Is my money safe in a savings account?

Yes, as long as the bank is FDIC-insured and your balance does not exceed $250,000. You can check if a bank is FDIC-insured by visiting the FDIC's website or calling the bank directly. The bank is required to tell you on your account statements and disclosures whether it is insured.

Why is the interest rate on my savings account so low?

Interest rates on savings accounts change based on what the Federal Reserve does. When the Fed lowers its rates, banks lower the rates they offer on savings accounts. Banks also offer lower rates on traditional savings accounts because they are competing with other products like money market accounts and certificates of deposit (CDs), which may offer higher rates.

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

No, except to cover fees you owe the bank. The bank cannot withdraw money to pay a debt you owe to someone else. If you owe money to a creditor or the government, they would need a court order to take money from your account, and the bank would notify you first.
