What you earn depends on the bank's rate and how much you have saved

A high yield savings account earns interest at a rate set by the bank, usually between 4% and 5.35% annual percentage yield (APY) as of early 2024, though this changes as the Federal Reserve adjusts its benchmark rate. The actual dollars you earn each month depend on two things: the APY the bank offers and your account balance. A $10,000 balance at 5% APY earns roughly $50 per month, or $600 per year. A $50,000 balance at the same rate earns about $250 per month, or $2,500 per year.

Banks calculate interest daily but usually deposit it monthly. The interest compounds, meaning you earn interest on your interest—though the effect is small in savings accounts because the rates and timeframes are modest compared to investments held for decades. If you leave $10,000 in an account earning 5% APY for one year without touching it, you will have $10,500 at the end.

Key Takeaways

  • High yield savings rates range from roughly 4% to 5.35% APY and change when the Federal Reserve adjusts its benchmark rate.
  • Your monthly earnings equal your balance multiplied by the APY, divided by 12—a $20,000 balance at 5% APY earns about $83 per month.
  • Interest compounds daily but is usually deposited monthly, so you earn small amounts of interest on your interest.
  • Banks are required to hold your money in reserve and insure deposits up to $250,000 through the FDIC, which is why rates are lower than investment returns.

How rates change and why they vary between banks

The Federal Reserve sets a target range for the federal funds rate, which is the interest rate banks charge each other for overnight loans. When the Fed raises or lowers this rate, banks adjust their savings account rates within weeks or months. During 2023 and early 2024, the Fed held rates high to fight inflation, which pushed high yield savings rates to their highest levels in years. If the Fed cuts rates, banks will lower their savings rates too—sometimes immediately, sometimes over several months.

Different banks offer different rates even when the Fed's rate is the same. Online banks like Marcus, Ally, and American Express Personal Savings typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. A traditional bank might offer 0.01% APY while an online bank offers 5.30% APY on the same day. Shopping around matters: the difference between 4.5% and 5.3% on a $50,000 balance is $400 per year.

Some banks offer promotional rates for new customers—for example, 5.50% APY for the first three months, then dropping to 4.75%. Read the fine print to see when the rate changes and what the long-term rate will be.

The trade-off between safety and earnings

High yield savings accounts earn less than stocks, bonds, or other investments because the money is may provide safe. The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per account holder per bank, meaning if the bank fails, you get your money back. Banks must keep a portion of deposits in reserve and cannot lend out all the money, which limits how much interest they can pay. In exchange, you never lose your principal and you can withdraw money without penalty (though some banks require a notice period).

If you are saving for something you need within one to three years—a down payment, an emergency fund, a car—a high yield savings account protects your money while earning more than a regular savings account. If you are saving for retirement or a goal decades away, stocks or bonds historically earn more over long periods, but they fluctuate in value and you can lose money in the short term.

How to calculate what you will earn

The formula is simple: Balance × APY ÷ 12 = Monthly earnings. If you have $25,000 in an account earning 5% APY, multiply $25,000 by 0.05 to get $1,250 per year, then divide by 12 to get about $104 per month. Most banks show your projected annual earnings on their website or app before you open an account.

Keep in mind that if you add or withdraw money during the month, your earnings for that month will be different. If you start with $25,000 and deposit $5,000 halfway through the month, you will earn interest on $25,000 for half the month and $30,000 for the other half. Banks calculate this daily, so the math is precise even though you see only the monthly total.

Interest is taxable income. At the end of the year, the bank sends you a 1099-INT form showing how much interest you earned, and you report it on your tax return. If you earned $1,200 in interest and you are in the 24% tax bracket, you owe roughly $288 in federal income tax on that interest (though state taxes may apply too).

When rates are likely to change

The Federal Reserve meets eight times per year to decide whether to raise, lower, or hold its benchmark rate. Banks usually adjust savings rates within days or weeks of a Fed decision. If you are watching rates and considering moving money, check what the Fed's next meeting date is—you can find this on the Federal Reserve's website. If a rate cut is expected soon, you might wait to see if your current bank lowers its rate before moving to a competitor.

Rates have been unusually high since 2023 because the Fed raised rates aggressively to fight inflation. Historically, high yield savings rates have been as low as 0.5% to 1% when the Fed's rates were low. There is no way to predict exactly when rates will fall, but if inflation continues to decline, the Fed will likely cut rates eventually, and savings rates will follow.

Comparing accounts to find the best rate

Use a rate-tracking website like Bankrate, DepositAccounts, or DepositAccounts.com to see current rates across dozens of banks. These sites update daily and let you sort by APY, minimum balance, and whether the account has monthly fees. Most high yield savings accounts have no monthly fees and no minimum balance, but confirm this before opening.

Check whether the bank is FDIC-insured by searching the FDIC's Bank Find tool on their website. If you have more than $250,000 to save, you can open accounts at multiple banks to keep all your money insured—each bank covers up to $250,000 per account holder. Some people open accounts at three or four banks to spread large balances across the insurance limit.

Once you open an account, set a reminder to check rates every few months. If your bank's rate drops below competitors by 0.5% or more, you can move your money to a higher-paying bank. Most transfers take three to five business days, and there are no penalties for moving money out of a savings account.

Frequently Asked Questions

Can I lose money in a high yield savings account?

No. Your principal is protected by FDIC insurance up to $250,000 per bank. The interest rate can go down, which means you earn less, but you cannot lose the money you deposited. The only way to lose money is if the bank fails and you have more than $250,000 in that bank, in which case the amount over $250,000 is not covered.

How often is interest added to my account?

Interest is calculated daily based on your balance, but most banks deposit it monthly. Some banks deposit it quarterly or even daily. Check your bank's website or account agreement to see the schedule. The APY quoted is always the annual rate, so monthly deposits will be roughly one-twelfth of that amount.

Is high yield savings better than a money market account?

High yield savings accounts and money market accounts often offer similar rates and both are FDIC-insured. Money market accounts sometimes let you write checks or use a debit card, while savings accounts usually require transfers or ATM withdrawals. Compare the rates and features at your bank—whichever offers a higher rate for the access you need is the better choice.

What happens to my interest if rates drop?

Your interest earnings will decrease because the bank's APY will be lower. For example, if your rate drops from 5% to 4%, a $10,000 balance will earn $50 per month instead of $42 per month. Your principal stays the same—only the interest you earn going forward is affected.

Do I have to report high yield savings interest on my taxes?

Yes. The bank sends you a 1099-INT form at the end of the year showing all interest earned, and you report it as income on your tax return. Even small amounts of interest must be reported. If you earned less than $10 in interest, the bank may not send a 1099-INT, but you still report it if you received one.
