Most savings accounts do earn interest, but the rate varies widely by bank and account type
A savings account earns interest when the bank pays you a percentage of the money you keep deposited. The bank uses your deposits to lend to other customers, and they share a portion of what borrowers pay back. How much you earn depends on the interest rate the bank offers, how much money sits in your account, and how often the interest compounds—meaning how often the bank adds earned interest back into your balance so it earns interest too.
Not every savings account earns the same rate. Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. Some accounts offer tiered rates, where you earn more interest if your balance stays above a certain threshold. Others offer promotional rates that are high for a few months, then drop. The Federal Reserve sets a benchmark rate that influences what banks offer, so rates change over time based on economic conditions.
The amount you earn is usually small unless your balance is substantial. If you keep $1,000 in an account earning 0.01% annually, you'll earn about 10 cents per year. At 4.5% annually—a rate some online banks offered in 2023—that same $1,000 would earn roughly $45 per year. The difference between a 0.01% account and a 4.5% account on $10,000 is the difference between $1 and $450 per year.
Key Takeaways
- Savings account interest rates range from near zero at some traditional banks to 4% or higher at online banks, depending on current market conditions and the bank's business model.
- Interest compounds, meaning you earn interest on the interest already added to your account, so the longer money sits untouched, the more it grows.
- High-yield savings accounts at online banks typically pay more than regular savings accounts at traditional banks, but both are FDIC-insured up to $250,000.
- The interest rate your bank offers can change at any time, so checking your account statement or the bank's website shows you what you're currently earning.
How interest compounds and why timing matters
Compounding is the mechanism that makes interest grow faster over time. When the bank adds interest to your account, that interest becomes part of your balance. The next time interest is calculated, you earn interest on the original deposit plus the interest already added. Most savings accounts compound daily or monthly, meaning the bank recalculates and adds interest that frequently.
The difference between daily and monthly compounding is small on modest balances but becomes meaningful at larger amounts or higher rates. An account earning 4% compounded daily will grow slightly faster than one earning 4% compounded monthly, because the daily calculation happens 30 times per month instead of once. Over a year, the difference on $10,000 might be $20 to $30, depending on the exact rate and compounding frequency.
Time is the other factor that makes compounding work. Money that sits untouched for five years earns more than money that sits for one year, even at the same rate. This is why moving money into a savings account early, even if the rate is modest, can matter more than waiting for a higher rate later.
The difference between savings accounts and other deposit accounts
A regular savings account is not the only place to earn interest on money you deposit. Money market accounts, certificates of deposit (CDs), and high-yield savings accounts all earn interest, but they work differently and offer different rates.
A high-yield savings account is a savings account that pays a higher interest rate than a regular savings account. The trade-off is usually that you must maintain a minimum balance or accept that the rate can change. High-yield accounts are offered mostly by online banks and some credit unions. They are FDIC-insured the same way regular savings accounts are.
A certificate of deposit (CD) is an account where you agree to leave money untouched for a set period—three months, one year, five years, or longer. In exchange, the bank pays a higher interest rate than a savings account. If you withdraw the money before the term ends, you pay a penalty, usually a few months' worth of interest. CDs make sense if you know you won't need the money for a specific period.
A money market account is a hybrid between a savings account and a checking account. It usually pays interest higher than a regular savings account but lower than a CD. You can write checks or use a debit card, but the bank limits how many withdrawals you can make per month. Money market accounts are also FDIC-insured.
What affects the interest rate your bank offers
Banks set their own interest rates, but they do not set them in a vacuum. The Federal Reserve's benchmark rate—called the federal funds rate—is the starting point. When the Fed raises its rate, banks have more incentive to offer higher rates to attract deposits. When the Fed lowers its rate, banks lower what they offer. The lag between a Fed change and a bank's response can be weeks or months.
Competition also drives rates. Online banks with low overhead can offer higher rates than traditional banks with physical branches. During periods when banks are competing hard for deposits, rates rise across the industry. During periods when deposits are plentiful, rates fall. This is why the same account type at the same bank might pay 0.5% one year and 4.5% the next.
Your own account history and balance can affect the rate you see. Some banks offer promotional rates to new customers only. Others offer tiered rates where balances above $100,000 earn more than balances below $25,000. A few banks offer different rates based on how long you've been a customer. Always check the specific terms for the account you're considering, because the advertised rate may not explore to your situation.
How to find out what your account is earning right now
Your bank statement shows the interest you earned in the previous month or quarter. The statement lists the interest rate, the amount of interest added, and your new balance. If you bank online, you can usually see this information in your account dashboard without waiting for a statement. Some banks show the annual percentage yield (APY), which is the rate you'll earn over a full year if you don't withdraw anything.
If you want to compare what you're earning to what other banks offer, visit the banks' websites directly. Most banks display current rates prominently on their savings account pages. Websites like Bankrate and DepositAccounts aggregate current rates from many banks, so you can see what's available without visiting each bank individually. Keep in mind that rates change frequently, so a rate you see today may be different next week.
If you have not checked your rate in several months, it may have changed. Banks can lower rates without notifying you in advance, though they must notify you before the change takes effect. If your rate has dropped significantly and other banks are offering more, moving your money to a different bank is straightforward—you open a new account, transfer the balance, and close the old account.
Why some accounts earn almost no interest
Traditional brick-and-mortar banks often offer savings rates below 0.1%, which is nearly nothing. This happens because these banks have high costs—physical locations, staff, ATM networks—and they do not need to compete aggressively for deposits. Customers often keep money at these banks for convenience rather than rate, so the bank has no incentive to pay more.
Checking accounts almost never earn interest, or earn so little it rounds to zero. Banks treat checking accounts as transaction accounts, not savings vehicles. The bank makes money on overdraft fees and other charges, not on the interest they pay you. If you want interest, a savings account or money market account is the right product.
Some savings accounts have fees that eat into the interest you earn. A monthly maintenance fee of $5 or $10 can wipe out the interest on a small balance. Always check whether an account has fees before opening it. Many online banks waive fees entirely, which is one reason their net return is higher even if the advertised rate is the same.
Frequently Asked Questions
Is the interest I earn on a savings account taxed?
Yes. Interest income is taxable as ordinary income at the federal level and in most states. Your bank will send you a 1099-INT form at the end of the year if you earned $10 or more in interest. You report this on your tax return. The amount you owe depends on your tax bracket, so $100 in interest might cost you $12 to $37 in taxes depending on your income level.
Can a bank lower my interest rate without warning?
Banks can lower rates without advance notice, but they must notify you before the change takes effect. The notification usually comes by email or mail. If you disagree with the lower rate, you have the right to close the account. Many banks lower rates when the Federal Reserve cuts its benchmark rate, so rate drops often happen in clusters across the industry.
What happens to my interest if I withdraw money before the end of the month?
For regular savings accounts, you still earn interest on the money that was in the account. Interest is calculated on your average balance or your balance on a specific day each month, depending on the bank's method. Withdrawing money mid-month reduces the balance used for that month's calculation, so you earn less interest that month, but you do not lose interest you already earned in previous months.
Is my interest earnings protected if the bank fails?
Yes. The FDIC insures savings accounts up to $250,000 per depositor per bank, including the principal and any interest earned. If the bank fails, the FDIC pays you the full amount, including interest accrued up to the date of failure. This protection applies to regular savings accounts, high-yield savings accounts, and money market accounts.
Why do online banks pay more interest than traditional banks?
Online banks have lower operating costs because they do not maintain physical branches or large staff. They pass some of these savings to customers in the form of higher interest rates. Traditional banks have higher overhead, so they keep more of the interest income they collect from loans. Both types of banks are equally safe if they are FDIC-insured, so the main difference is the rate you earn.
