Yes, savings accounts earn interest — but the amount depends on the bank and the rate they offer
A savings account is a bank account designed to hold money you're not spending right now. In exchange for keeping your money there, the bank pays you interest — a small percentage of your balance, 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 catch is that interest rates vary widely. A savings account at one bank might earn 4.5% per year, while another earns 0.01% per year. That difference is enormous over time. A $10,000 deposit earning 4.5% grows to $10,450 in one year. The same $10,000 at 0.01% grows to only $10,001. The bank you choose matters far more than the amount you deposit.
Key Takeaways
- Savings accounts earn interest because banks pay you a percentage of your balance in exchange for holding your money.
- Interest rates vary from less than 0.01% to over 5% depending on the bank and the type of account.
- High-yield savings accounts, usually offered by online banks, pay significantly more interest than traditional brick-and-mortar banks.
- Interest is typically added to your account monthly or daily, and the more frequently it compounds, the more you earn.
- The Federal Reserve's interest rate decisions affect how much banks are willing to pay, so rates change over time.
How banks decide what interest rate to pay you
Banks set their own interest rates based on what the Federal Reserve does. The Federal Reserve is the central bank of the United States, and it sets a target range for the interest rate that banks charge each other for overnight loans. When that rate is high, banks have more money to work with and are willing to pay savers more. When it's low, banks pay less.
But banks don't pass the Federal Reserve's rate directly to you. Instead, they use it as a starting point and then decide how much to pay based on competition, their own costs, and how much they need your deposits. A bank that wants to attract more savings might pay 4.5%. A bank that doesn't need deposits might pay 0.01%. You're shopping for the best rate the same way the bank is shopping for the best borrowers.
The difference between traditional banks and high-yield savings accounts
A traditional savings account at a brick-and-mortar bank — the kind with a building on your street — typically earns between 0.01% and 0.5% per year. These banks have physical locations, employees, and high operating costs, so they don't need to pay much interest to attract deposits. Many people keep money there for convenience, not for growth.
A high-yield savings account is offered by online banks or online divisions of larger banks. These banks have no physical branches, lower overhead, and can afford to pay more. High-yield accounts currently earn between 4% and 5.3% per year, depending on the bank and the current interest rate environment. The tradeoff is that you manage the account online or by phone, not in person.
Both types of account are insured by the Federal Deposit Insurance Corporation (FDIC), which means your money is protected up to $250,000 per account. The insurance is the same; the interest rate is what changes.
How interest is calculated and added to your account
Banks calculate interest using your account balance and the annual percentage rate (APR). If your account earns 4.5% APR and you have $10,000, the bank calculates how much interest you've earned each day or month, then adds it to your account.
Most banks add interest monthly, though some add it daily. When interest is added more frequently, you earn slightly more because of compounding — you earn interest on the interest that was already added. If a bank adds interest daily, you earn interest on yesterday's balance plus yesterday's interest. Over a year, daily compounding earns more than monthly compounding, but the difference is usually small unless your balance is very large.
You can see how much interest you've earned by checking your account statement. The statement shows your opening balance, deposits, withdrawals, interest earned, and your closing balance. Some banks also show your APR on the statement so you can verify the rate they promised.
What happens to interest rates when the Federal Reserve makes changes
The Federal Reserve meets eight times per year to decide whether to raise, lower, or hold steady the interest rate it charges banks. When the Fed raises rates, banks usually raise the rates they pay to savers within days or weeks. When the Fed lowers rates, banks lower what they pay you, sometimes immediately.
This means the interest rate on your savings account is not locked in. It can go up or down without warning. If you open a high-yield account earning 4.8% today, that rate might drop to 4.2% in three months if the Fed cuts rates. You're not may provide the rate you see when you open the account.
Some banks are slower to raise rates when the Fed raises them, but faster to lower rates when the Fed cuts them. This is why comparing rates across banks matters — a bank that was competitive three months ago might not be now.
Why some savings accounts earn almost nothing
If you have a savings account at a traditional bank earning 0.01% or 0.05%, the bank is not being generous — it's being realistic about what it needs to pay. Traditional banks have high costs and often don't need to attract more deposits because they have enough customers already. They're betting that most people won't move their money for a slightly higher rate, and they're usually right.
Some people keep money in low-interest accounts for reasons other than growth: they want a physical branch nearby, they've had the account for years, or they don't know that higher rates exist. If you're saving for something specific and want your money to grow, a high-yield account is almost always worth the switch. The difference between 0.05% and 4.5% on $5,000 is $225 per year — real money.
What to watch out for when comparing savings accounts
When you're looking at different savings accounts, compare the APR, not just the interest rate. The APR includes any fees the bank charges, so it's the true cost or benefit. Some banks advertise a high rate but charge monthly fees that eat into your earnings.
Also check the minimum balance requirement. Some accounts require you to keep a certain amount in the account at all times, or the rate drops or fees kick in. If you have $500 and the account requires $2,500, you won't may have access to for the advertised rate.
Finally, confirm that the bank is FDIC-insured. This protects your money up to $250,000 if the bank fails. Most banks are insured, but it's worth verifying on the FDIC's website before you move your money.
Frequently Asked Questions
Can I lose money in a savings account?
No. Your principal — the money you deposit — is protected by FDIC insurance up to $250,000. You won't earn much interest if rates are low, but you won't lose what you put in. The only way to lose money is if you withdraw more than you deposited, which is your choice, not the bank's.
How often should I check my interest rate?
Check it once or twice a year, especially if the Federal Reserve has made changes. If your rate has dropped significantly below what other banks are offering, moving your money to a higher-paying account takes about a week and costs nothing. Banks make it easy to transfer money between institutions.
Is a high-yield savings account safe?
Yes, as long as the bank is FDIC-insured. Online banks are regulated the same way as traditional banks, and your deposits are protected the same way. The only difference is that you can't walk into a branch — you manage everything online or by phone.
What's the difference between a savings account and a money market account?
A money market account is a hybrid between a savings account and a checking account. It usually earns interest like a savings account but lets you write checks or use a debit card like a checking account. The tradeoff is that money market accounts often have higher minimum balances and lower interest rates than high-yield savings accounts.
Do I have to pay taxes on the interest I earn?
Yes. Interest is considered income by the IRS. If you earn more than $10 in interest in a year, the bank sends you a 1099-INT form, and you report that interest on your tax return. The amount is usually small, but it counts as taxable income.
