High-yield savings accounts pay between 4% and 5.35% APY right now, but the exact rate depends on the bank and changes weekly

The interest you earn in a high-yield savings account (HYSA) is not fixed. Banks set their own rates, and those rates move up and down based on what the Federal Reserve does with its benchmark interest rate. When you open an account, you get whatever rate that bank is offering that day. If rates drop next month, your rate drops too. If rates rise, your rate may or may not rise—banks are slower to pass increases to savers than they are to raise what they charge borrowers.

Right now, the highest-paying accounts sit around 4.5% to 5.35% APY. Banks like Marcus, Ally, American Express Personal Savings, and Wealthfront Cash Account have been competitive in this range, but you need to check the current rate before you deposit money, because it will have changed since this article was written. The difference between 4.5% and 5.35% matters: on $10,000, that gap is $85 per year.

The rate you see advertised is the APY—annual percentage yield. That number already includes the effect of compounding (interest earned on interest), so you do not have to do extra math. The bank deposits interest into your account monthly, and that interest starts earning interest the next month.

Key Takeaways

  • High-yield savings rates range from roughly 4% to 5.35% APY depending on the bank, and these rates change weekly as the Federal Reserve adjusts its benchmark rate.
  • The rate you see when you open an account is the rate you get that day, but it will change if the Fed raises or lowers rates—usually downward for savers when the Fed cuts.
  • APY already includes compounding, so a 5% APY account earning monthly interest will give you slightly more than 5% of your balance over a year.
  • Comparing rates across banks matters because a 1% difference on $50,000 costs you $500 per year in lost interest.

How banks decide what rate to offer you

Banks do not set HYSA rates in a vacuum. The Federal Reserve sets a target range for the federal funds rate—the rate banks charge each other for overnight loans. When the Fed raises that rate, banks have more incentive to offer higher rates on savings to attract deposits. When the Fed cuts rates, banks cut what they pay savers because they have less incentive to compete for deposits.

The second factor is competition. If one bank raises its HYSA rate to 5.2% and others are stuck at 4.8%, customers move money to the higher-paying bank. Banks that want to keep deposits have to match or come close. Online banks (Marcus, Ally, American Express) tend to offer higher rates than brick-and-mortar banks because they have lower overhead and can pass savings to customers. Your local bank probably pays 0.01% APY on savings because they do not need to compete for deposits—people keep money there for convenience.

A third factor is the bank's own funding needs. A bank that needs deposits urgently may raise rates higher than competitors. A bank flush with deposits may lower rates because they do not need more money coming in.

What happens to your rate when the Fed changes course

The Federal Reserve meets eight times a year to decide whether to raise, lower, or hold its benchmark rate steady. When the Fed raises rates, banks usually raise HYSA rates within days or weeks—they want to attract deposits before competitors do. When the Fed cuts rates, banks cut HYSA rates much more slowly, sometimes taking weeks or months to lower what they pay savers.

This asymmetry is why savers often feel like they get the short end. If you locked in 5.35% and the Fed cuts rates by 0.5%, your rate might drop to 4.85% within a month. But if the Fed raises rates by 0.5%, your rate might not move for weeks, and when it does, it may only go up 0.25%. Banks pass rate increases to borrowers faster than to savers.

You cannot lock in a rate in a HYSA the way you can with a CD (certificate of deposit). Your rate is variable, meaning it moves with the market. If you want a may provide rate, you would need to move money into a CD, but CDs lock your money away for a set term—usually three months to five years—and you pay a penalty if you withdraw early.

How much interest you actually earn depends on your balance and how long you keep it there

Interest accrues daily but is usually deposited monthly. If you have $10,000 in an account paying 5% APY, you earn roughly $50 per month (or $416.67 per year, because of compounding). If you have $50,000, you earn roughly $250 per month. The math is straightforward: multiply your balance by the APY, divide by 12.

The catch is that interest only accrues on money that is actually in the account. If you deposit $10,000 on the first of the month and withdraw $5,000 on the 15th, the bank calculates interest on the average balance or the daily balance, depending on the account. Most HYSAs use daily balance, so you earn interest on $10,000 for 14 days and $5,000 for the remaining days of the month. The interest you earn that month is lower than if you had kept the full $10,000 in the account.

This is why HYSAs work best for money you are not touching—an emergency fund, a down payment you are saving for, a sinking fund for a known expense. If you move money in and out constantly, you lose the compounding benefit and earn less interest overall.

The difference between APY and APR

APY (annual percentage yield) and APR (annual percentage rate) are not the same thing, and banks use them for different products. APY includes the effect of compounding—interest earned on interest. APR does not. For a savings account, you always want to see the APY, because that is what you will actually earn.

If a bank advertises 5% APY on a savings account, that means after one year, your money will have grown by 5% (assuming you do not withdraw anything and rates do not change). If a bank advertises 5% APR on a loan, that is the interest rate before compounding is factored in—the actual cost to you is slightly higher because interest compounds.

For savings accounts, the difference between APY and APR is small because compounding happens monthly or daily. But it is real. A 5% APY account will earn you slightly more than 5% of your balance over a year because of compounding.

Why rates vary so much between banks right now

At any given moment, HYSA rates can range from 0.01% at a traditional bank to 5.35% at an online bank. The spread exists because of competition, overhead, and how aggressively each bank is trying to attract deposits.

Online banks like Marcus, Ally, and American Express have lower costs than brick-and-mortar banks. They do not maintain physical branches, do not pay tellers, and do not have the same real estate overhead. They pass those savings to customers in the form of higher interest rates. A traditional bank with branches in every neighborhood cannot compete on rate because their costs are higher.

Some banks also use high rates as a loss leader—they offer an unusually high rate for a few months to attract deposits, then lower the rate once customers are in the door. Before you move money to a bank offering an unusually high rate, check whether that rate is promotional (temporary) or standard (permanent). The bank should disclose this clearly, but read the fine print.

How to compare rates across banks

Do not rely on a single source to find the best rate. Banks change rates frequently, and different websites update at different speeds. Check the rate directly on the bank's website before you open an account. Write down the APY, the date you checked it, and whether the rate is promotional or standard.

Then check two or three other banks you are considering. The difference between 4.8% and 5.2% is $40 per year on every $10,000 you deposit. Over five years, that is $200 in lost interest. It is worth spending 15 minutes to find the highest rate.

Keep in mind that the highest rate today may not be the highest rate next month. If you are comfortable moving money between banks, you can chase rates—close an account at one bank and open at another when rates shift. Many people do this. If you prefer stability and do not want to manage multiple accounts, pick a bank with a solid rate and stay put, knowing your rate will move with the Fed.

Frequently Asked Questions

Can I lock in a high-yield savings rate so it does not go down?

No. High-yield savings accounts have variable rates, meaning they move with the market. If you want a locked rate, you need a CD (certificate of deposit), which fixes your rate for a set term—usually three months to five years. The tradeoff is that your money is locked away, and you pay a penalty if you withdraw early.

What happens to my interest if I withdraw money before the end of the month?

Most banks calculate interest on your daily balance, so you earn interest on the money you had in the account each day. If you deposit $10,000 and withdraw $5,000 halfway through the month, you earn interest on $10,000 for the first half and $5,000 for the second half. You do not lose the interest you already earned, but you earn less that month because your balance was lower.

Is the interest I earn in a high-yield savings account taxable?

Yes. Interest income is taxable as ordinary income. The bank will 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. This is one reason to keep emergency funds in a HYSA rather than a regular savings account—the higher interest rate offsets some of the tax burden, though you still owe tax on what you earn.

Why did my rate drop even though the Fed did not cut rates?

Banks sometimes lower rates on their own, independent of Fed action. A bank may lower rates if it has enough deposits and does not need to attract more money, or if it is facing pressure on profit margins. Check your bank's website or call to confirm the new rate, and consider moving money to a higher-paying bank if the drop is significant.

How often does the interest get added to my account?

Most high-yield savings accounts deposit interest monthly, though some do it daily or quarterly. Check your account agreement to see how often interest is credited. Monthly is most common. The interest is added to your balance and starts earning interest the next month (compounding).
