What you earn depends on the bank, the account type, and the current rate environment

The interest rate on a savings account is set by your bank and changes based on what the Federal Reserve does with its benchmark rate. Right now, rates vary widely: some banks offer 4.5% to 5.35% APY on high-yield savings accounts, while traditional brick-and-mortar banks often pay 0.01% to 0.05%. The difference between these two is real money—on $10,000, you'd earn roughly $450 per year at 4.5% versus $1 per year at 0.01%.

Your actual earnings depend on three things: the APY the bank advertises, how much you keep in the account, and how long it sits there. Banks calculate interest daily but usually credit it monthly. If you deposit $5,000 at 5% APY and leave it untouched for a year, you'll earn about $250. If you withdraw half of it after six months, you earn less because the interest compounds on a smaller balance for the second half of the year.

Key Takeaways

  • High-yield savings accounts at online banks currently pay 4.5% to 5.35% APY, while traditional banks typically pay under 0.1%.
  • Interest is calculated daily but credited monthly, so your balance grows gradually throughout the year.
  • The APY you see advertised can change at any time—banks lower rates when the Federal Reserve cuts its benchmark rate.
  • Money market accounts and certificates of deposit sometimes pay more than savings accounts, but they come with withdrawal limits or lock-in periods.
  • The FDIC insures up to $250,000 per depositor per bank, so your principal is protected even if the bank fails.

How banks set their rates

Banks don't choose their rates in a vacuum. The Federal Reserve sets a target range for the federal funds rate—the rate at which banks lend to each other overnight. When the Fed raises this rate, banks eventually raise what they pay on savings accounts because they can earn more on their own investments. When the Fed cuts rates, banks cut what they pay you.

The lag between a Fed move and a rate change on your account can be weeks or months. Banks raise rates quickly when the Fed tightens (because they want to attract deposits), but they cut rates more slowly when the Fed loosens (because they're in no rush to pay you less). Online banks tend to move faster than traditional banks because they have lower overhead and compete directly on rate.

Competition also matters. If five online banks all offer 5.2% and one offers 4.8%, the lagging bank will usually raise its rate within days. Traditional banks with physical branches don't compete as hard on rate because they rely on convenience and brand loyalty instead.

The difference between APY and interest rate

APY (annual percentage yield) includes the effect of compounding—interest earned on interest. The interest rate (or APR) is the raw percentage before compounding is factored in. For savings accounts, the difference is usually small because interest compounds monthly or daily, not annually. But the APY is always the number that matters for comparing accounts, because it shows you the true annual return.

If a bank advertises 5% APY, that's the number you use to calculate what you'll earn. Multiply your balance by the APY and divide by 12 to get a rough monthly earning. On $10,000 at 5% APY, you earn about $42 per month (before compounding makes it slightly more).

How rates change and what triggers a drop

Savings account rates move in one direction at a time, and they move together. When the Fed raised rates from near zero in 2022 and 2023, high-yield savings rates climbed from 0.5% to over 5%. When the Fed paused and then began cutting in late 2024, rates started falling. A single Fed rate cut of 0.25% usually triggers a 0.25% drop in savings rates within a few weeks.

You won't see a rate drop announced in advance. Banks change rates on their own schedule, sometimes with a few days' notice on their website and sometimes with none. If you're earning 5.2% and your bank drops to 4.8%, you have the option to move your money to a bank still paying 5.2%. There's no penalty for moving savings between banks—only certificates of deposit and some money market accounts charge early withdrawal fees.

Rates can also rise if the Fed raises its benchmark rate again. This is less common than rate cuts, but it happens. If you're in a high-yield savings account, you benefit immediately when rates go up. If you're in a traditional bank account paying 0.01%, you probably won't see any increase.

Comparing savings accounts to other places to keep cash

A savings account is one of several places to earn interest on cash you're not spending. Money market accounts often pay the same rate as high-yield savings but may require a higher minimum balance. Certificates of deposit (CDs) lock your money away for a set term—three months, six months, one year, five years—and usually pay slightly more than savings accounts in exchange for that lock-in. If you withdraw early, you pay a penalty (usually a few months' worth of interest).

Money market funds and Treasury bills are other options, but they're not FDIC-insured the way bank savings accounts are. A Treasury bill is backed by the U.S. government, so it's extremely safe, but you have to buy them through a brokerage and they're less convenient than a bank account. Money market funds are mutual funds that invest in short-term debt, and they carry a small risk of loss.

For most people, a high-yield savings account is the simplest choice: no lock-in period, FDIC insurance up to $250,000, and rates that move with the market. If you know you won't need the money for a year or more, a CD might pay slightly more, but you give up the flexibility.

What happens to your interest if rates drop

If you're earning 5.2% and rates fall to 4.5%, your bank will lower your rate to match the market. You don't lose the interest you've already earned—that's credited to your account and stays there. But going forward, you earn less on your balance. This is why some people move money to CDs when rates are high: a one-year CD locks in today's rate for the full year, even if rates drop tomorrow.

The tradeoff is that if rates rise, you're stuck with the lower CD rate. You can't move the money without paying an early withdrawal penalty. Savings accounts give you flexibility: you can move your money to a higher-paying bank anytime rates rise elsewhere.

How to find the highest rate available right now

The highest rates are almost always at online banks, not at banks with physical branches. Online banks have lower costs and compete directly on rate. You can compare current rates on financial websites that track them, or you can visit the banks' websites directly. Rates change frequently, so a comparison from last week may be out of date.

When you're comparing, make sure you're looking at the APY, not the interest rate. Also check the minimum balance requirement—some banks require $25,000 or more to earn the advertised rate, while others have no minimum. FDIC insurance covers up to $250,000 per depositor per bank, so if you have more than that, you'll need to split it across multiple banks to keep it all insured.

Opening an account at an online bank takes 10 to 15 minutes. You'll need your Social Security number, a government ID, and a way to fund the account (usually a transfer from another bank). There's no cost to open or maintain the account, and you can close it anytime without penalty.

Frequently Asked Questions

Will my interest rate stay the same forever?

No. Banks change rates based on what the Federal Reserve does and what competitors offer. High-yield rates can drop 0.5% to 1% within a few months if the Fed cuts rates. If you want to lock in a rate, open a CD instead of a savings account.

How often is interest added to my account?

Interest is calculated daily but credited monthly at most banks. Some credit it quarterly. The APY accounts for this compounding, so you don't need to do anything—the bank handles it automatically.

Can I lose money in a savings account?

No, as long as your balance is under $250,000 and the bank is FDIC-insured. Your principal is protected. Interest rates can fall, but you won't lose the money you deposited or the interest already credited.

Is a high-yield savings account safe?

Yes, if the bank is FDIC-insured. Check the bank's website or the FDIC's bank search tool to confirm. FDIC insurance covers up to $250,000 per depositor per bank, even if the bank fails.

What's the difference between a savings account and a money market account?

Money market accounts often pay the same rate as savings accounts but may require a higher minimum balance and limit how many withdrawals you can make per month. Savings accounts have no withdrawal limits. For most people, a savings account is simpler.
