Yes, savings accounts earn interest, but the amount depends on the bank and the rate they offer

When you put money in a savings account, the bank pays you interest — a small percentage of your balance, calculated and added to your account on a regular schedule. The bank uses your money to lend to other customers and make investments, so they share a portion of what they earn with you. The more money you keep in the account and the higher the interest rate, the more interest you accumulate over time.

Interest is not automatic or may provide at every bank. Different banks offer different rates, and rates change based on what the Federal Reserve does with its benchmark interest rate. Some accounts earn almost nothing; others earn a meaningful return. You have to look at what your specific bank is offering right now to know what you will actually earn.

Key Takeaways

  • Interest rates on savings accounts vary by bank and change over time, so checking your bank's current rate is the only way to know what you will earn.
  • Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs.
  • Interest is usually compounded daily or monthly, meaning you earn interest on your interest as well as your original deposit.
  • The Federal Deposit Insurance Corporation (FDIC) protects your deposits up to $250,000 per account, regardless of how much interest you earn.

How interest rates are set and why they change

Banks set their own savings account rates, but they follow the Federal Reserve's lead. When the Federal Reserve raises its benchmark rate, banks typically raise their savings rates too. When the Fed lowers rates, banks lower theirs. This is why the interest you earn on a savings account can be much higher one year and much lower the next — the Fed's decisions ripple through the entire banking system.

The rate you see advertised is called the Annual Percentage Yield (APY). This is the total return you would earn in one year if you left your money untouched. A bank might advertise 4.50% APY, which means if you had $10,000 in the account for a full year with no deposits or withdrawals, you would earn $450 in interest (before taxes). But that rate is only good for as long the bank chooses to offer it. Banks can change rates at any time, usually with a few days' notice.

The difference between online banks and traditional banks

Online banks almost always offer higher interest rates than banks with physical branches. This is because they do not have the cost of maintaining buildings, hiring tellers, and running a physical network. They pass those savings on to customers in the form of higher rates. An online bank might offer 4.50% APY while a traditional bank offers 0.01% APY on the same type of account.

The tradeoff is convenience. With an online bank, you cannot walk into a branch to deposit cash or speak to someone face-to-face. You deposit money by transfer or mobile check deposit, and you handle all your banking through a website or app. If you do not need in-person banking, an online bank is usually the better choice for earning interest on savings.

How compounding multiplies your interest

Most savings accounts use compound interest, which means the bank calculates interest on your original balance plus any interest you have already earned. Interest is usually compounded daily or monthly. Daily compounding is slightly better because you earn interest on your interest more often.

Here is a concrete example: if you have $5,000 in an account earning 4.50% APY with daily compounding, the bank divides the annual rate by 365 days and calculates interest each day. After one day, you earn about $0.62. After 30 days, you have earned roughly $18.50, but some of that $18.50 is interest earned on the interest from earlier days. Over a full year, compounding means you earn slightly more than if the bank just calculated 4.50% once at the end of the year. The longer your money sits in the account, the more noticeable the effect becomes.

What happens to your interest when rates drop

If you open a savings account at 4.50% APY and the Federal Reserve cuts rates, your bank will eventually lower your rate too. You will not lose the money you have already earned, but your future interest will be smaller. Some banks lower rates within days of a Fed cut; others wait weeks. You can switch to a different bank if your current rate becomes uncompetitive, though you will have to move your money to the new account.

This is why it makes sense to shop around for rates regularly. A rate that is competitive today might be below average in six months. Setting a reminder to check your bank's rate every few months helps you catch when it is time to move your money to a higher-paying account.

Taxes on savings account interest

Interest you earn on a savings account is taxable income. At the end of each year, your bank sends you a Form 1099-INT showing how much interest you earned. You report this amount on your tax return, and you owe federal income tax on it (and state income tax in most states). The amount of tax depends on your overall income and tax bracket.

If you earned less than $10 in interest during the year, your bank may not send you a Form 1099-INT, but you still owe tax on that interest if you file a return. Keep your own records of interest earned in case you need them. High-yield savings accounts earn more interest, which means a larger tax bill, but you are still coming out ahead because you are earning more money overall.

Comparing savings accounts to other ways to save

Savings accounts are not the only place to put money and earn a return. Money market accounts often offer rates similar to savings accounts but may require a higher minimum balance. Certificates of Deposit (CDs) typically offer higher rates than savings accounts, but you have to lock your money away for a set period (three months, one year, five years, etc.) or pay a penalty to withdraw it early. Treasury bills and other government securities can offer competitive rates and are backed by the U.S. government.

A savings account is the most flexible option because you can withdraw your money anytime without penalty. This makes it ideal for an emergency fund or money you might need soon. If you have money you will not touch for several years, a CD or Treasury bill might earn you more. Many people use a combination: a high-yield savings account for emergencies and shorter-term goals, and CDs or other investments for longer-term money.

Frequently Asked Questions

How often is interest added to my savings account?

Interest is usually compounded daily but posted to your account monthly. This means the bank calculates interest every day, but you see the total added to your balance once a month. Some banks post interest more or less frequently, so check your account agreement to be sure.

Can I lose money in a savings account?

Your principal — the money you deposit — is protected by FDIC insurance up to $250,000 per account. You will not lose your deposit. However, if inflation is higher than your interest rate, the purchasing power of your money decreases over time, even though the dollar amount stays the same.

What is the highest interest rate I can get on a savings account?

Rates change constantly based on Federal Reserve decisions and bank competition. As of now, online banks offer rates between 4% and 5% APY, but this varies. Check current rates at multiple banks to find the highest available rate at the time you are ready to open an account.

Do I have to pay fees on a savings account?

Many banks charge monthly maintenance fees, overdraft fees, or fees for excessive withdrawals. Some banks waive these fees if you maintain a minimum balance or set up direct deposit. Read the fee schedule before opening an account, as high fees can eat into the interest you earn.

What happens to my interest if I withdraw money mid-month?

Interest is calculated on your average daily balance during the month. If you withdraw money partway through the month, you earn interest only on the amount you held for those days. The exact calculation depends on your bank's method, so ask if you want to know the specifics.
