3.5% APY is competitive but not the highest rate available

Whether 3.5% APY is good depends on what other banks are offering at the moment you're looking. In late 2024, online banks and credit unions regularly offer rates between 4.0% and 5.35%, so 3.5% falls below the current market average. If your bank is offering 3.5%, you're earning more than you would in a traditional brick-and-mortar savings account (which often pay 0.01% to 0.05%), but you're leaving money on the table compared to what's available elsewhere.

The rate you see today won't stay the same. Banks adjust their APY based on what the Federal Reserve does with interest rates. When the Fed raises rates, banks typically raise what they pay depositors. When the Fed cuts rates, banks cut their rates too—sometimes quickly. A 3.5% rate that was excellent six months ago might be below average in six months more.

The real question is not whether 3.5% is objectively good, but whether it's the best rate you can get right now for the type of account you need. That depends on how often you need to withdraw money, whether you want FDIC insurance, and how much you're willing to move your money to chase higher rates.

Key Takeaways

  • 3.5% APY is below the current market average for online savings accounts, where rates between 4.0% and 5.35% are common.
  • The rate you earn changes when the Federal Reserve changes interest rates, so comparing rates only makes sense for the current moment.
  • A high-yield savings account at an online bank typically pays more than a traditional bank's savings account, but requires you to move your money.
  • The difference between 3.5% and 4.5% on $10,000 is about $100 per year, so the gap matters more as your balance grows.

How to compare 3.5% to other rates you can actually get

Start by checking what your current bank is offering. If you have a checking account at a large national bank like Chase, Bank of America, or Wells Fargo, your savings account probably earns less than 0.1% APY. Switching to their "high-yield" savings product might get you to 3.5% or slightly higher, but you won't have to move your money to a different bank.

Then look at what online-only banks are offering. Banks like Marcus, Ally, American Express Personal Savings, and Wealthfront Cash Account regularly post rates on their websites. Credit unions also publish their rates, and some offer competitive APY to members. Write down three or four options with their current rates, then check whether each one charges monthly fees (most don't) and whether your deposits are insured by the FDIC or NCUA.

The math is simple: take the difference between 3.5% and the highest rate you found, multiply it by your account balance, and divide by 12. That's how much more you'd earn per month by switching. On $5,000, the difference between 3.5% and 4.5% is about $8 per month. On $50,000, it's about $83 per month. If the difference is small and you like your current bank, staying put is reasonable. If it's large and you don't use your savings account for daily transactions, moving makes financial sense.

Why online banks pay more than traditional banks

Online banks have lower overhead costs than banks with physical branches. They don't pay rent on thousands of locations, they don't employ tellers, and they don't maintain ATM networks. That savings gets passed to depositors as higher interest rates. A traditional bank needs to keep some of its deposits in reserve and lend out the rest to make money on the spread between what it pays you and what it charges borrowers. An online bank can do the same thing more efficiently.

This doesn't mean online banks are riskier. As long as your deposits are insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per account, your money is protected the same way it is at a big bank. Most online banks display their FDIC insurance status clearly on their website. If you don't see it, ask before you open an account.

What happens to your rate if the Federal Reserve changes interest rates

The Federal Reserve doesn't set the interest rate your bank pays you. But it does set the federal funds rate, which is the rate banks charge each other to borrow overnight. When the Fed raises this rate, banks have more incentive to pay you more to keep your deposits. When the Fed cuts the rate, banks cut what they pay you—sometimes within days.

If you lock in 3.5% today and the Fed cuts rates next month, your bank will likely cut your rate too. Savings accounts don't have fixed rates the way a CD (certificate of deposit) does. Your APY can change at any time, and banks are required to notify you before the change takes effect, but they're not required to ask your permission. This is why comparing rates only tells you what's true right now, not what will be true in three months.

If you want a may provide rate that won't change, a CD is the tool for that. You lock in a rate for a set period—three months, six months, one year, five years—and the bank can't lower it. The trade-off is that you can't withdraw the money without paying a penalty. For money you might need soon, a savings account is more flexible even if the rate can change.

When 3.5% might be the right choice anyway

If your current bank is offering 3.5% and you use that bank for checking, bill pay, and transfers, staying put has value. Moving your savings to a different bank means setting up a new login, linking it to your checking account for transfers, and learning a new interface. If you only have a small balance—under $5,000—the extra interest you'd earn by switching might not be worth the hassle.

You might also choose 3.5% if the bank offering it has features you need. Some banks offer better customer service, easier mobile apps, or the ability to deposit checks by phone camera. Some credit unions offer lower rates but have local branches where you can withdraw cash without fees. These factors are real, and they're worth money to you even if they don't show up in the APY.

If you're saving for something specific in the next few months and you want to know exactly how much interest you'll earn, a CD might be better than either a 3.5% savings account or a higher-rate account where the rate could drop. A three-month CD at 4.5% locks in your rate and lets you move the money when it matures without penalty.

The difference between APY and APR on savings accounts

APY stands for Annual Percentage Yield. APR stands for Annual Percentage Rate. On a savings account, APY is what matters. APY includes the effect of compounding—the interest you earn on your interest. If your account compounds daily (which most do), you earn a tiny bit of interest every day, and tomorrow you earn interest on that interest too.

APR doesn't include compounding, so it's always lower than APY for the same stated rate. Banks are required to show you the APY, not the APR, when advertising savings accounts. If you see a rate advertised without "APY" next to it, that's a red flag—ask the bank to clarify.

How to move your money if you find a better rate

Opening a new savings account at a different bank takes 10 to 15 minutes online. You'll need your Social Security number, a government ID, and your current address. The bank will ask how much you plan to deposit and may run a soft credit check (which doesn't affect your credit score).

Once your account is open, you can transfer money from your old bank using an ACH transfer. This usually takes one to three business days. Some banks offer a "transfer service" where they pull the money from your old account for you—you just give them your old bank's routing number and account number. Others let you initiate the transfer from your old bank's website by adding the new bank as an external account.

Don't close your old savings account until the transfer is complete and you've confirmed the money arrived. Once you're sure everything went through, you can close the old account. If you had automatic transfers set up to that account (like a paycheck deposit), update those before you close it.

Frequently Asked Questions

Will my 3.5% rate stay the same forever?

No. Savings account rates change whenever the bank decides to change them, usually in response to Federal Reserve rate changes. Your bank must notify you before lowering your rate, but the rate is not may provide. If you want a rate that won't change, open a CD instead.

Is it worth switching banks for a 1% difference in APY?

It depends on your balance. On $10,000, a 1% difference is $100 per year. On $100,000, it's $1,000 per year. If you're moving a large balance and the new bank has no monthly fees, switching usually makes sense. For small balances, the extra interest might not be worth the time to set up a new account.

Can I lose money in a savings account if rates drop?

No. Your balance stays the same. If your rate drops from 3.5% to 2.5%, you earn less interest going forward, but you don't lose what you already have. Your account balance only goes down if you withdraw money or if the bank fails (which is extremely rare for FDIC-insured banks).

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

A money market account usually pays a slightly higher rate than a savings account and may come with a debit card or checkbook, but it often has a higher minimum balance requirement. Both are FDIC-insured and both have variable rates. For most people, a high-yield savings account is simpler.

Should I move my money every time I find a higher rate?

Not necessarily. Banks that offer the highest rates today often lower them quickly once they've attracted deposits. If you move your money every month chasing the highest rate, you'll spend a lot of time on transfers for small gains. Pick a bank with a competitive rate and a solid reputation, then check your rate once or twice a year.
