Yes, most savings accounts earn interest, but the amount 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 there. The bank uses your money to lend to other customers and invests it, then shares a portion of what it makes with you. How much you earn depends on the annual percentage yield (APY) the bank offers, how much money sits in your account, and how long it stays there.
Not every savings account earns the same rate. A traditional bank might offer 0.01% APY, meaning you earn almost nothing. An online bank might offer 4.5% to 5.35% APY on the same $10,000. The difference between those two banks on $10,000 over one year is roughly $450 versus $5. That gap matters if you're saving money you won't touch for months or years.
Interest compounds, which means you earn interest on your interest. If your account compounds daily, the bank calculates and adds interest to your balance every single day. If it compounds monthly, that happens once a month. The more often it compounds, the slightly more you earn, though the difference is usually small unless your balance is very large.
Key Takeaways
- Savings accounts do earn interest, but rates range from nearly 0% at traditional banks to over 5% at online banks, so shopping around changes how much money you make.
- The interest you earn depends on three things: the APY the bank offers, your account balance, and how long the money stays deposited.
- Interest compounds, meaning you earn money on the interest you've already earned, though the effect is small unless your balance is large or the rate is high.
- You can compare rates across banks using their websites or rate-tracking sites, and rates change frequently so what's highest today may not be next month.
- Money in a savings account is insured up to $250,000 by the FDIC, so you won't lose your principal even if the bank fails.
How to calculate what you'll earn
The formula is straightforward: multiply your balance by the APY, then divide by 12 if you want a monthly estimate. A $5,000 balance at 4.5% APY earns roughly $225 per year, or about $18.75 per month. At 0.01% APY, that same $5,000 earns $0.50 per year.
Online calculators on bank websites do this math for you. You enter your balance, the APY, and how often interest compounds, and the calculator shows you the total you'll have after one year, five years, or whatever timeframe you choose. This is useful for comparing two banks side by side.
Keep in mind that APY rates change. A bank offering 5% today might drop to 4.5% next month if the Federal Reserve lowers interest rates. Rates also rise when the Fed raises rates. Your existing balance keeps earning at the old rate until the bank changes it, but new deposits and any promotional rates usually follow the new rate immediately.
Why rates differ so much between banks
Traditional banks with physical branches charge more to operate those branches, pay more staff, and have higher overhead. They pass some of that cost to customers by offering lower interest rates. Online banks have no branches, fewer employees, and lower costs, so they can afford to pay you more of what they earn.
Some banks also use low rates as a trade-off for other services. A bank might offer 0.01% interest but charge no monthly fee and let you open an account with $1. Another bank might offer 5% but require a $25,000 minimum balance or charge a monthly fee if you fall below it. Read the fine print on minimum balances, fees, and withdrawal limits before opening an account.
Banks also compete for customers in different ways. A new online bank might offer a promotional rate of 5.5% for the first three months to attract deposits, then drop to 4.8%. A large national bank might keep rates low because customers stay for convenience rather than interest. Shopping around takes 20 minutes and can mean hundreds of dollars per year in difference.
The difference between APY and APR
APY (annual percentage yield) includes the effect of compounding. APR (annual percentage rate) does not. For savings accounts, always look at the APY, because that's what you actually earn. APR is used for loans and credit cards, where it tells you what you'll pay.
A bank might advertise "5% interest" but the fine print shows 4.87% APY. The difference is compounding. If interest compounds daily, you earn slightly more than if it compounds monthly, and the APY reflects that. The APY is the number that matters for comparing two savings accounts.
Where to find current rates and compare banks
Bank websites show their current APY on the savings account product page. Most banks list rates prominently because they use them to attract customers. You can visit five banks' websites in 15 minutes and write down their rates.
Rate-tracking websites like Bankrate, DepositAccounts, and NerdWallet update rates daily and let you filter by account type, minimum balance, and whether you want a brick-and-mortar bank or online-only. These sites don't sell accounts themselves; they're just tracking what banks offer. You still open the account directly with the bank.
When you find a rate you like, check whether it's a promotional rate that expires or a standard rate that stays. Read the terms about minimum balance, monthly fees, and how many withdrawals you can make per month. Some savings accounts limit you to six withdrawals per month, though that rule has loosened at many banks.
How interest is taxed
Interest you earn on a savings account is taxable income. If you earn $100 in interest during a year, you owe federal income tax on that $100. The bank sends you a 1099-INT form in January showing how much interest you earned, and you report it on your tax return.
The tax you owe depends on your overall income and tax bracket. If you're in the 22% tax bracket and earn $100 in interest, you'll owe roughly $22 in federal tax on it. State income tax may apply too, depending on where you live. Some states don't tax interest income, while others do.
This is one reason high-yield savings accounts matter for larger balances. If you have $50,000 earning 5% APY, you earn $2,500 per year in interest. If that same $50,000 earns 0.01% at a traditional bank, you earn $5 per year. The difference in taxes is roughly $550 per year, which is real money.
When a savings account makes sense versus other options
A savings account is the right place for money you might need within the next one to three years. The interest is modest, but your money is safe, insured by the FDIC up to $250,000, and you can withdraw it without penalty whenever you want. You won't get rich on savings account interest, but you won't lose money either.
If you're saving for something 10 or 20 years away, like retirement, a savings account earns too little. You'd want to look at investments like index funds or bonds, which historically earn more over long periods. But those come with risk: you can lose money in the short term. A savings account never loses your principal.
Money you need within the next few months should stay in a savings account, not invested. Money you won't touch for years can afford to take on more risk for higher potential returns. A savings account is the bridge between those two.
Frequently Asked Questions
Can I lose money in a savings account?
No. Your principal is insured by the FDIC up to $250,000, so even if the bank fails, you get your money back. Interest rates can fall, so you might earn less than you expected, but your balance won't shrink unless you withdraw money yourself.
How often does interest get added to my account?
It depends on the bank and how often the account compounds. Most accounts compound daily or monthly. You can see how often on the account terms page or by calling the bank. Daily compounding means interest is calculated and added every day, though you might only see the total added once per month when the statement posts.
What happens to my interest if I withdraw money?
You keep the interest you've already earned. If you withdraw $1,000 from a $5,000 balance, you keep all the interest that's been added so far. You just earn less interest going forward because your balance is now lower. Some accounts charge a penalty for withdrawals, so check the terms before opening.
Do I have to report savings account interest on my taxes?
Yes, if you earn more than $10 in interest during the year. The bank sends you a 1099-INT form showing the total, and you report it as income on your tax return. Even small amounts should be reported; the IRS matches 1099 forms to tax returns.
Is a high-yield savings account the same as a regular savings account?
They're the same type of account with the same FDIC protection, but high-yield accounts offer much higher APY rates, usually 4% to 5.5% compared to 0.01% to 0.5% at traditional banks. The catch is that high-yield accounts are almost always at online banks with no branches, and rates can change monthly.
