Yes, savings accounts earn money through interest, but the amount depends on the rate your bank offers and how much you keep in the account
A savings account makes money by paying you interest — a percentage of your balance that the bank adds to your account on a set schedule, usually monthly or daily. The bank pays you this interest because they lend out the money you deposit to other customers. The interest rate varies widely: some accounts pay nearly nothing, while others (particularly online banks and high-yield savings accounts) currently pay 4% to 5% annually. A $10,000 balance at 0.01% earns about $1 per year. The same $10,000 at 4.5% earns roughly $450 per year.
The money you earn is real — it gets added to your account balance — but it is small compared to what you might expect. Most people open savings accounts to keep money safe and accessible, not to get rich. The interest is a bonus, not the main reason to save.
Key Takeaways
- Interest rates on savings accounts range from nearly 0% to around 5%, depending on the bank and account type, so the rate matters more than the account itself.
- Interest compounds over time, meaning you earn interest on your interest, but the effect is small unless your balance is large or you leave money untouched for years.
- Online banks and high-yield savings accounts currently pay much more than traditional brick-and-mortar banks, sometimes 50 times as much on the same balance.
- The interest you earn is taxable income, so you will receive a 1099-INT form from your bank if you earn $10 or more in a year.
How interest rates are set and why they change
Banks set their own interest rates based on what the Federal Reserve does. When the Fed raises its benchmark rate, banks have more room to pay higher rates on savings accounts. When the Fed cuts rates, banks lower what they pay you. This is why the same account might pay 4.5% one year and 2% the next — the bank is following the market, not making a random choice.
Different banks pay different rates even when the Fed rate is the same. Online banks typically pay more because they have lower overhead costs (no branches, fewer employees). A traditional bank might pay 0.01% while an online bank pays 4.5% on the exact same type of account. Shopping around matters: moving $50,000 from a 0.01% account to a 4.5% account means earning $2,500 more per year instead of $5.
Rates change frequently, sometimes weekly. If you want to know what your current account pays, log in to your bank's website or call and ask. Do not assume the rate you opened with is still accurate.
How compound interest works in a savings account
Compound interest means you earn interest on your interest. If your account pays interest monthly, the bank adds that month's earnings to your balance, and next month you earn interest on the larger amount. Over many years, this creates growth that outpaces simple math.
The effect is real but often overstated. A $1,000 balance at 4.5% annual interest earns about $45 in year one. In year two, you earn interest on $1,045, so you make roughly $47. After 10 years of leaving it untouched, you have about $1,553. That is $553 in total earnings — useful, but not transformative. Compound interest works best when you have a large balance, a high rate, and decades of time. For most people with modest savings, the difference between compound and simple interest is a few dollars per year.
The difference between savings accounts and money market accounts
A money market account is a hybrid between a savings account and a checking account. It usually pays interest (sometimes higher than a regular savings account), but it also lets you write checks or use a debit card. The tradeoff is that money market accounts often require a higher minimum balance to open and may charge fees if your balance drops below that minimum.
For earning interest, the rate matters far more than the account type. A high-yield savings account at an online bank will almost always pay more than a money market account at a traditional bank. Compare the actual rates, not the account names. Some banks advertise "money market" accounts that pay less than their savings accounts because the rates are set independently.
What happens to your interest if rates drop
If you lock money into a savings account and rates fall, your rate falls with it (unless you have a promotional rate with an end date). Banks adjust rates on savings accounts constantly — sometimes daily. This is different from a certificate of deposit (CD), where you lock in a rate for a fixed period (3 months, 1 year, 5 years) and that rate does not change, even if the market rate drops.
If you think rates might fall, a CD protects you by guaranteeing your rate. If you think rates might rise, a savings account lets you benefit when the bank raises its rate. Most people choose savings accounts for flexibility — you can withdraw money anytime without penalty — and accept that the rate will change.
Taxes on savings account interest
The interest you earn is taxable income. If you earn $10 or more in interest during a calendar year, your bank sends you a Form 1099-INT by January 31 of the following year. You report this on your tax return as interest income. The tax you owe depends on your overall income and tax bracket — it could be 10%, 22%, 35%, or another rate depending on your situation.
This means earning $450 in interest might cost you $100 to $150 in taxes, depending on your bracket. The interest is still yours to keep after taxes, but it is smaller than the gross number. If you have multiple savings accounts or CDs, each bank sends its own 1099-INT, and you add them all together on your return.
Comparing savings accounts to other ways to store money
A savings account is not the only place to put money you want to keep safe. Money market funds, CDs, Treasury bills, and I Bonds all earn interest or returns. A money market fund (not the same as a money market account) is a mutual fund that invests in short-term debt and currently pays around 5% to 5.5%. A 1-year CD might pay 4.8% to 5.2%. A 4-week Treasury bill pays around 5.3%. An I Bond (a government savings bond) pays a rate that changes every six months, currently around 5.27%.
The tradeoff is access. A savings account lets you withdraw money instantly. A CD locks your money for a set period — withdraw early and you pay a penalty. A Treasury bill or I Bond also has restrictions. For money you might need soon, a savings account is simpler. For money you can leave alone for months or years, a CD or Treasury bill often pays more.
Frequently Asked Questions
How much money do I need in a savings account to make it worth it?
There is no minimum that makes interest "worth it" — even $100 earns something. But the math is clearer with larger amounts. A $100 balance at 4.5% earns $4.50 per year. A $10,000 balance earns $450. If you have less than $1,000, the interest is usually under $5 per year, so you are saving for safety and access, not income.
Can I lose money in a savings account?
No. Your balance cannot go down because of the account itself. The bank guarantees your principal. However, inflation can reduce what your money buys — if inflation is 3% and your account pays 1%, you are losing purchasing power even though your balance grows. High-yield accounts that pay 4% to 5% currently keep pace with or beat inflation.
Do I have to pay taxes on interest if I earn very little?
You report all interest income on your tax return, but you may not owe tax if your total income is below the threshold for your filing status. For 2024, a single person with no other income does not owe federal tax if they earn less than $14,600. Interest counts toward that total, so if you earn $200 in interest and have no other income, you file but owe no tax.
What if my bank goes out of business?
The Federal Deposit Insurance Corporation (FDIC) insures savings accounts up to $250,000 per depositor per bank. If your bank fails, the FDIC pays you back in full. This protection is automatic — you do not have to do anything. If you have more than $250,000, spread it across multiple banks to keep all of it insured.
Should I move my money to a higher-paying account?
If your current account pays 0.01% and you have $5,000 or more, moving to an account paying 4.5% means earning roughly $225 more per year on that balance. The move takes a few days and involves no cost. The main reason not to move is if you use your current bank for checking and want to keep everything in one place, but most online banks offer both checking and savings.
