Most savings accounts earn between 0.01% and 5.35% APY, depending on the bank and account type

The interest your savings account earns depends almost entirely on which bank you choose and what type of account you open. A traditional savings account at a large national bank might earn 0.01% APY, meaning $10,000 would earn about $1 per year. A high-yield savings account at an online bank might earn 4.5% to 5.35% APY on the same $10,000, earning $450 to $535 per year. The difference between these two accounts is real money—and the gap exists because online banks have lower overhead costs and pass some of that savings to depositors.

Interest rates change constantly. The Federal Reserve sets a target range for the federal funds rate, and banks adjust their savings account rates in response. When the Fed raises rates, banks typically raise savings rates within weeks or months. When the Fed cuts rates, savings rates fall more slowly—banks are quicker to raise rates than to lower them. This means the rate you see today may be different in three months, six months, or a year.

Key Takeaways

  • Online banks and credit unions typically offer 4% to 5.35% APY on savings accounts, while traditional brick-and-mortar banks often offer 0.01% to 0.5% APY.
  • The interest rate you earn depends on the bank's business model and funding costs, not on how much money you deposit or how long you keep it there.
  • Money market accounts and certificates of deposit (CDs) may offer higher rates than savings accounts, but they come with restrictions on how often you can withdraw.
  • Your interest earnings are taxed as ordinary income in the year you earn them, which reduces your actual take-home return.

Why rates differ so much between banks

A large national bank like Bank of America or Wells Fargo operates thousands of branches with employees, rent, and technology infrastructure. These costs are high. The bank can afford to pay depositors very little interest because customers stay with them for convenience—the branch near their home, the familiar name, the ATM network. A customer earning 0.01% APY might not leave because switching banks feels like work.

An online bank like Marcus, Ally, or American Express Personal Savings has no branches, no tellers, and minimal physical overhead. The bank's main cost is technology and customer service. To attract deposits, online banks compete on interest rate. They offer 4.5% to 5.35% APY because that rate is still profitable for them—they lend out deposits at higher rates—and it pulls customers away from traditional banks. A customer earning 0.01% at a big bank will move $50,000 to an online bank for 5% APY. That customer's $50,000 is worth the cost of acquisition.

Credit unions operate on a membership model and return profits to members rather than shareholders. Many credit unions offer savings rates between 3% and 5% APY. The catch is that some credit unions require membership in a specific group—you might need to work for a certain employer, live in a certain county, or belong to a certain organization. Others have opened membership to anyone.

How to find the current rates offered by different banks

The best way to compare rates is to visit bank websites directly. Most banks display their current APY prominently on the savings account page. Write down the rate, the minimum balance required to earn that rate, and any fees. Some banks offer their highest rate only on balances above $25,000 or $100,000; others offer the same rate on any balance.

Comparison websites like Bankrate, DepositAccounts, and NerdWallet aggregate current rates from many banks and update them regularly. These sites let you filter by account type, minimum balance, and other features. The rates on these sites are usually accurate, but always confirm the rate on the bank's own website before opening an account—rates can change daily.

Call or email the bank directly if you have questions about whether a rate applies to your situation. Some banks offer different rates to different customers based on factors like account age, direct deposit, or linked checking account. Asking takes five minutes and can save you money.

Money market accounts and CDs may pay more, but with strings attached

A money market account is a hybrid between a savings account and a checking account. It typically earns a higher interest rate than a regular savings account—sometimes 0.5% to 1% higher—but limits how many times per month you can withdraw money. Federal rules allow up to six withdrawals per month; some banks allow fewer. If you exceed the limit, the bank may charge a fee or convert your account to a regular savings account.

A certificate of deposit (CD) locks your money away for a set period—three months, six months, one year, five years. In exchange, the bank pays a higher rate. A one-year CD might pay 4.8% APY while a savings account pays 4.5% APY. If you withdraw before the CD matures, 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 and want to lock in a rate before rates fall.

High-yield savings accounts have no withdrawal limits and no lock-in period. You can move your money whenever you want. For most people, a high-yield savings account is better than a money market account or CD because you get nearly the same rate with more flexibility.

What happens to your interest when tax time comes

Banks report interest earnings to the IRS on a Form 1099-INT if you earn $10 or more in interest during the year. You must report this interest as ordinary income on your tax return. If you earned $500 in interest, you pay income tax on that $500 at your marginal tax rate. If you are in the 24% tax bracket, you owe $120 in federal tax on that $500, leaving you with $380 in actual after-tax earnings.

This matters when comparing accounts. A savings account earning 5% APY sounds better than one earning 4%, but after taxes the difference shrinks. The higher-rate account is still better, but not by as much as the APY suggests. Some people use tax-advantaged accounts like IRAs or 529 plans to earn interest without paying tax on it each year, but those accounts have contribution limits and withdrawal rules.

How interest compounds and what it means for your money

Banks calculate and add interest to your account daily, weekly, or monthly depending on the bank's policy. Most online banks compound daily, meaning they calculate interest on your balance each day and add it to your account. The next day, they calculate interest on the new, slightly higher balance. This compounding effect is small over short periods but adds up over years.

If you deposit $10,000 in a savings account earning 5% APY with daily compounding, you earn about $500 in the first year. In the second year, you earn interest on $10,500, so you earn about $525. The extra $25 came from compounding. Over 10 years, compounding adds hundreds of dollars. Over 30 years, it adds thousands. The longer your money sits, the more compounding helps you.

Rates will change, and you should check yours once or twice a year

The rate you earn today is not may provide to stay the same. When the Federal Reserve cuts rates, banks lower savings rates within weeks. When the Fed raises rates, banks raise savings rates, but sometimes slowly. A bank might raise rates quickly to attract new deposits, then stop raising them even as the Fed continues to raise. You might find that your rate has fallen below what new customers are offered.

Set a reminder to check your savings account rate every six months. If your rate has fallen significantly below what other banks are offering, move your money. Switching banks takes a few days and costs nothing. The difference between 2% APY and 4.5% APY on $50,000 is $1,250 per year. That is worth an afternoon of paperwork.

Frequently Asked Questions

Do I earn interest on money I deposit mid-month?

Yes. Most banks calculate interest daily based on your balance at the end of each day. If you deposit $5,000 on the 15th, you earn interest on that $5,000 from the 15th onward. You do not earn interest on it for the first 14 days of the month, but you earn it for the remaining days.

What is the difference between APY and APR?

APY (annual percentage yield) includes the effect of compounding and shows what you actually earn. APR (annual percentage rate) does not include compounding. For savings accounts, always look at APY. For loans, APR is more relevant, though APY matters there too if interest compounds frequently.

Can I lose money in a savings account?

No. Your principal is protected by FDIC insurance up to $250,000 per bank per account type. You will not earn much interest in a low-rate account, but you will not lose what you deposit. The only way to lose money is if you withdraw funds and pay a penalty, which happens only with CDs.

Should I move my money to a higher-rate account?

If your current account earns less than 1% APY and you have more than $1,000 saved, moving to a 4% to 5% account will earn you hundreds of dollars per year. The move takes a few days and costs nothing. If your account earns 4.5% and another offers 4.6%, the difference is small enough that switching may not be worth your time.

What happens if a bank fails?

Your deposits up to $250,000 are insured by the FDIC (Federal Deposit Insurance Corporation). If the bank fails, the FDIC pays you back. This protection applies to savings accounts, checking accounts, and money market accounts. CDs are also covered. You are protected even if the bank goes under tomorrow.
