Yes, most savings accounts earn interest, but the rate varies widely by bank and account type

Interest on a savings account is money the bank pays you for keeping your money there. The bank lends out the deposits it holds, and it shares a portion of what it earns with you as interest. The amount you earn depends on the annual percentage yield (APY), which is the rate the bank advertises, and how much money sits in your account.

Not every savings account earns the same rate. A high-yield savings account at an online bank might pay 4% to 5% APY, while a traditional savings account at a brick-and-mortar bank might pay 0.01% APY. The difference between these two accounts can mean hundreds of dollars per year on the same deposit. The rate also changes over time—banks raise and lower their rates based on what the Federal Reserve does with its benchmark interest rate.

Interest compounds, meaning you earn interest on your interest. If you deposit $10,000 at 5% APY and leave it untouched for a year, you earn $500. The next year, you earn interest on $10,500, not just the original $10,000. The more often interest compounds (daily, monthly, or quarterly), the more you earn, though the difference is usually small.

Key Takeaways

  • Banks pay interest on savings accounts as a percentage of your balance, stated as an annual percentage yield (APY).
  • High-yield savings accounts at online banks typically pay 4% to 5% APY, while traditional bank savings accounts often pay less than 0.1% APY.
  • Interest rates change when the Federal Reserve adjusts its benchmark rate, so the APY your bank offers today may be different in three months.
  • Interest compounds, so you earn returns on the interest you already earned, which increases your total balance over time.
  • The bank is required to disclose the APY before you open an account, so you can compare rates across different banks.

How banks set interest rates on savings accounts

Banks do not set rates randomly. The Federal Reserve sets a target range for the federal funds rate, which is the interest rate banks charge each other for overnight loans. When the Fed raises this rate, banks typically raise the rates they pay on savings accounts. When the Fed lowers it, banks lower their rates too.

However, banks do not all move at the same speed or to the same degree. Online banks often raise their rates faster than traditional banks because they have lower overhead costs and compete more aggressively for deposits. A traditional bank might wait weeks or months to raise its savings rate after the Fed moves, while an online bank might raise it within days.

Banks also set rates based on how much competition they face in your area and how much deposit money they need. A bank that needs more deposits might offer a higher rate to attract customers. A bank that already has plenty of deposits might keep its rate lower.

The difference between APY and interest rate

The interest rate and the annual percentage yield (APY) are not the same thing, though banks sometimes use the terms loosely. The interest rate is the percentage the bank pays on your balance. The APY includes the effect of compounding—how often the bank adds interest to your account.

For example, a bank might advertise a 5% interest rate compounded daily. The actual APY would be slightly higher than 5% because you earn interest on your interest every single day. The bank must disclose the APY in writing before you open an account, so you can compare one bank's offer to another fairly.

Always look at the APY when comparing savings accounts, not the interest rate alone. Two banks might advertise the same interest rate, but if one compounds daily and the other compounds monthly, the daily-compounding account will earn you more money.

How much interest you actually earn

The amount of interest you earn depends on three things: your account balance, the APY, and how long your money stays in the account. A simple formula shows the relationship: multiply your balance by the APY, then divide by the number of days in a year, then multiply by the number of days your money was in the account.

Here is a concrete example. If you deposit $5,000 in an account with a 4.5% APY and leave it there for one full year, you earn $225 in interest. If you deposit the same $5,000 at 0.01% APY (a typical rate at a traditional bank), you earn 50 cents in a year. The difference is $224.50—real money that stays in your pocket or goes to the bank depending on which account you choose.

The longer your money stays in the account, the more interest you earn. But interest only accrues on money that is actually in the account. If you withdraw $2,000 halfway through the year, you earn interest only on the remaining $3,000 for the second half of the year. Some banks calculate interest daily, so even a withdrawal on the last day of the month affects your earnings.

When interest is added to your account

Banks add interest to your account on a schedule they set. Some banks add interest monthly, some quarterly, and some daily. The schedule does not change how much total interest you earn over a year—a 4.5% APY is a 4.5% APY whether interest is added once a month or every day. However, if you withdraw money partway through a compounding period, daily compounding means you lose less interest than you would with monthly compounding.

You can see when interest was added by checking your account statement or transaction history. The deposit will show up as a credit to your account, usually labeled "interest paid" or "interest earned." If you do not see interest being added to an account that should be earning it, contact the bank to ask why.

Savings accounts with no interest or very low interest

Some savings accounts earn almost nothing. A traditional bank savings account might pay 0.01% APY, which means you earn $1 per year on a $10,000 deposit. This happens because traditional banks have higher costs—they maintain physical branches, employ tellers, and run customer service centers. They pass these costs on by paying lower rates.

Money market accounts and certificates of deposit (CDs) sometimes pay higher rates than regular savings accounts at the same bank, though they come with restrictions. A money market account might require a higher minimum balance or limit how many withdrawals you can make per month. A CD locks your money away for a set period—three months, one year, five years—and charges a penalty if you withdraw early.

If your bank is paying very low interest, moving your money to a high-yield savings account at an online bank is usually worth the effort. The difference in earnings can be substantial, especially if you have a large balance or plan to keep the money there for years.

How to find the current interest rate on savings accounts

Banks publish their current APY on their websites, usually on the page for each savings account product. You can compare rates across multiple banks by visiting their sites directly or using a rate-comparison tool. The Consumer Financial Protection Bureau (CFPB) does not maintain a rate comparison tool, but many financial websites do.

When you compare rates, make sure you are looking at the APY, not just the interest rate. Also check whether there are any fees that could reduce your earnings—some banks charge monthly maintenance fees or fees for falling below a minimum balance. A high APY does not matter if you lose $10 per month to fees.

Rates change frequently, so a rate you see today may be different next week. If you find a bank offering a rate you like, you can open an account, but understand that the rate may go down in the future if the Federal Reserve lowers its benchmark rate.

Frequently Asked Questions

Do I have to pay taxes on savings account interest?

Yes. Interest earned on a savings account is taxable income. If you earn $100 or more in interest during a calendar year, the bank will send you a Form 1099-INT, and you must report the interest on your tax return. Even if you earn less than $100, you still owe tax on it—the bank just does not have to send you a form.

Can a bank lower my interest rate without telling me?

Yes, banks can lower rates without advance notice on most savings accounts. However, they must disclose the new rate before it takes effect, usually by email or mail. If you want to know when your rate changes, check your account online or call the bank. Some banks notify customers when rates drop, but it is not required.

What happens to my interest if I withdraw money before the end of the year?

You earn interest only on the money that was actually in the account. If you deposit $5,000 and withdraw $2,000 after six months, you earn interest on $5,000 for six months and $3,000 for the remaining six months. Banks that compound interest daily calculate this precisely; banks that compound monthly may calculate it based on your balance on the last day of the month.

Is a high-yield savings account safe?

High-yield savings accounts at banks insured by the Federal Deposit Insurance Corporation (FDIC) are just as safe as traditional savings accounts. The FDIC insures deposits up to $250,000 per account holder per bank. Online banks are typically FDIC-insured, so your money is protected even if the bank fails.

Why do some banks offer much higher interest rates than others?

Online banks have lower operating costs because they do not maintain physical branches, so they can afford to pay higher rates and still make a profit. Traditional banks with many branches have higher costs and pay lower rates. Both are legitimate business models; the choice depends on whether you value in-person service or higher earnings.
