What you earn depends on the bank, the account type, and the current rate environment
The amount of interest a savings account pays you varies widely. A big bank might pay 0.01% annual percentage yield (APY), while an online bank might pay 4.50% or higher. The difference between these two is real money: on $10,000, one year at 0.01% earns $1, while 4.50% earns $450.
Banks set their own rates based on what the Federal Reserve does with its benchmark rate, how much competition they face, and their own business model. Online banks typically pay more because they have lower overhead costs. Credit unions sometimes pay more too, depending on their membership base and funding sources. The rates change over time—sometimes weekly—so what you see today may not be what you see in three months.
Your actual earnings also depend on how much you deposit, how long you leave it there, and whether the bank compounds interest daily, monthly, or quarterly. Daily compounding means you earn interest on your interest more often, which adds up faster over time.
Key Takeaways
- Online banks and credit unions typically pay 4% to 5% APY on savings accounts, while traditional brick-and-mortar banks often pay 0.01% to 0.05%.
- The Federal Reserve's rate changes drive what banks offer, so rates can shift significantly within months.
- Interest compounds at different frequencies—daily compounding earns you more than monthly or quarterly compounding on the same APY.
- You can compare rates across banks using their websites or rate-tracking sites, and switching banks costs nothing if you move your money to a higher-paying account.
How banks decide what rate to offer you
Banks borrow money from depositors (that's you) and lend it out to borrowers at a higher rate. The difference is their profit. When the Federal Reserve raises its benchmark rate, banks can charge borrowers more, so they can afford to pay depositors more to attract deposits. When the Fed lowers rates, banks lower what they pay you.
Competition also matters. In markets where many online banks operate, rates tend to be higher because banks fight for deposits. In markets where one or two big banks dominate, rates stay lower because customers have fewer choices. A bank's size and funding strategy matter too—a bank that relies heavily on deposits will pay more to attract them than a bank that funds itself through other means.
The type of account also affects the rate. A regular savings account typically pays less than a money market account or a certificate of deposit (CD). High-yield savings accounts are designed specifically to pay more, and they do—but they may have minimum balance requirements or other restrictions.
What "APY" means and how compounding works
APY (annual percentage yield) is the rate the bank advertises, and it already includes the effect of compounding. If a bank says 4.50% APY, that is the total you will earn in a year if you leave your money untouched. The APY accounts for how often the bank compounds your interest, so you do not have to do the math yourself.
Compounding means the bank pays interest on your interest. If you have $10,000 at 4.50% APY compounded daily, the bank calculates interest each day on your current balance (including yesterday's interest). After one day, you have $10,001.23. After 30 days, you have $10,037.50. After a year, you have $10,450. The daily compounding adds about $37.50 more than if the bank only paid once a year.
The difference between daily and monthly compounding is small on a savings account, but it adds up over years or on large balances. A $100,000 balance at 4.50% APY earns about $375 more per year with daily compounding than with monthly compounding.
Comparing rates across different banks
You can find current rates by visiting bank websites directly or using rate-tracking sites that update daily. Most banks list their APY prominently on their savings account pages. When you compare, make sure you are looking at the same account type—a high-yield savings account rate will not match a regular savings account rate at the same bank.
Pay attention to minimum balance requirements. Some banks offer high rates only if you keep a certain amount on deposit, often $2,500 or $25,000. If you fall below that, the rate drops. Others have no minimum. Read the fine print before you open an account.
Also check how the bank handles rate changes. Most banks can lower your rate at any time with notice (usually 30 days). Some banks may provide a rate for a set period. If you want to lock in a rate for longer, a CD might be better than a savings account, though CDs penalize you if you withdraw early.
How much you actually earn on different balances
The dollar amount you earn depends on three things: your balance, the APY, and how long you leave the money there. Here is what one year of interest looks like at different rates and balances:
| Balance | At 0.05% APY | At 1.00% APY | At 4.50% APY |
|---|---|---|---|
| $1,000 | $0.50 | $10 | $45 |
| $10,000 | $5 | $100 | $450 |
| $50,000 | $25 | $500 | $2,250 |
| $100,000 | $50 | $1,000 | $4,500 |
These numbers assume you do not add or withdraw money during the year. If you deposit money partway through the year, you earn interest only on the amount you have on deposit for the time you have it there. The bank calculates this automatically.
Why rates change and what to watch for
Rates move when the Federal Reserve changes its benchmark rate, which it does several times a year based on economic conditions. When inflation is high, the Fed raises rates to cool spending. When the economy slows, the Fed lowers rates to encourage borrowing and spending. Banks follow these moves within days or weeks.
You do not have to do anything when rates change. If your rate goes down, you can shop around and move your money to a bank offering more. If your rate goes up, you benefit automatically. Some people move their money every few months to chase the highest rate, while others pick a bank and stay put. Both approaches work—moving takes time and effort, but staying put means you might earn less than you could elsewhere.
Watch for promotional rates. Some banks offer a high rate for a limited time to attract new customers, then drop the rate after a few months. Read the terms before you open an account so you know when the promotional period ends and what your rate will be after.
Frequently Asked Questions
Is the interest I earn on a savings account taxed?
Yes. Interest income is taxable as ordinary income at your federal tax rate. Banks 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. Some states also tax interest income. The bank does not withhold taxes automatically, so you may owe money at tax time.
Can I move my money to a higher-paying bank without losing interest?
Yes. When you transfer money from one bank to another, you do not lose any interest you have already earned. The old bank pays you interest through the day you withdraw, and the new bank starts paying you interest the day your money arrives. There is no penalty for moving your money between banks.
What is the difference between a savings account and a money market account?
A money market account typically pays a higher rate than a regular savings account, but it may require a larger minimum balance and limit how many withdrawals you can make per month. Both are insured by the FDIC up to $250,000. The rate difference varies by bank, so compare before you open.
Do I need a certain amount of money to get a good interest rate?
No. Most online banks pay the same high rate whether you have $100 or $100,000 on deposit. Some banks offer tiered rates where you earn more if you have a larger balance, but these are less common now. Check the bank's terms to see if there is a minimum balance requirement.
What happens to my interest if I withdraw money before the year ends?
You earn interest only on the money you have on deposit for the time you have it there. If you deposit $10,000 on January 1 and withdraw $5,000 on July 1, you earn interest on $10,000 for six months and $5,000 for six months. The bank calculates this automatically—you do not have to do anything.
