3.5% APY is competitive but not the highest available

Whether 3.5% APY is good depends on what other banks are offering at the moment you're comparing. As of early 2025, online banks and credit unions regularly offer rates between 4.0% and 5.0% APY on savings accounts with no minimum balance. If your bank is paying 3.5%, you're earning more than a traditional brick-and-mortar bank (which typically pays 0.01% to 0.50%), but you're likely leaving money on the table compared to what's available elsewhere.

The rate environment changes constantly. The Federal Reserve sets the benchmark rate, and banks adjust their savings rates in response. A rate that was excellent six months ago may be below average today. The only way to know if 3.5% is good for you right now is to check what your current bank offers, then compare it to rates at three or four other institutions—particularly online banks, which usually have lower overhead and can pass higher rates to customers.

Key Takeaways

  • 3.5% APY beats traditional banks by a wide margin but falls below the 4.0% to 5.0% range that many online banks and credit unions offer.
  • The "good" rate changes month to month as the Federal Reserve adjusts its benchmark and banks respond, so comparison shopping is the only reliable test.
  • Online banks and credit unions typically pay more than national chains because they have lower operating costs and compete on rate rather than branch locations.
  • Moving your savings to a higher-rate account costs nothing and takes a few days; the difference compounds over time even on modest balances.

How to compare 3.5% to what's actually available

Start by checking rates at three categories of banks: your current institution, at least one online bank, and a credit union if you have membership. Sites like Bankrate, DepositAccounts, and the FDIC's National Rates and Rate Caps table show current rates across multiple institutions, updated daily. Write down the APY, any minimum balance requirement, and whether the rate is promotional (temporary) or standard.

Pay attention to the fine print. Some banks advertise a high rate but only on balances above $25,000, or they offer the rate for three months then drop it. A standard rate that applies to any balance is more useful for comparison than a promotional rate that expires. Also check whether the account compounds interest daily or monthly—daily compounding earns slightly more, but the difference is small on most balances.

What 3.5% actually earns on different account sizes

The real test of whether a rate is good is what it puts in your pocket. On a $10,000 balance, 3.5% APY earns about $350 per year. On $50,000, it earns about $1,750 per year. If you moved that same $50,000 to a 4.5% account, you'd earn about $2,250 per year—a difference of $500 that costs you nothing but a few minutes to switch.

That gap widens over time because of compounding. A $10,000 deposit earning 3.5% grows to about $10,357 after one year. The same deposit at 4.5% grows to about $10,459. Over five years, 3.5% gets you to about $11,876, while 4.5% gets you to about $12,461. The longer your money sits, the more the rate difference matters.

When 3.5% might actually be the right choice

If you're comparing 3.5% at a bank where you already have checking, direct deposit, and bill pay set up, the convenience of staying put has a real cost. But if switching takes you from 2.0% to 3.5%, that's a meaningful gain and worth the 10 minutes it takes to open a new account and transfer funds. The decision changes if you're comparing 3.5% to 4.8%—the extra 1.3% compounds to real money, especially on larger balances.

You should also consider whether the bank offers other features you need: no monthly fees, no minimum balance, no restrictions on how often you can withdraw, FDIC insurance (which protects up to $250,000 per account owner per bank), and customer service that's available when you need it. A slightly lower rate at a bank you trust and can reach is sometimes worth it, but only if the rate difference is small—less than 0.5 percentage points.

How rates move and what to expect next

Savings rates follow the Federal Reserve's benchmark rate, which the Fed adjusts based on inflation and economic conditions. When the Fed raises its rate, banks typically raise savings rates within weeks. When the Fed cuts, banks drop savings rates more slowly—they're quick to raise, slower to fall. This means if you see a rate you like, it's worth moving your money sooner rather than later, because rates can drop without warning.

You don't need to chase every 0.1% increase. But if your current rate is 3.5% and you find a bank offering 4.5% with no strings attached, the math favors moving. You can always move again later if rates rise further. Most banks make it straightforward to transfer money between institutions using the Automated Clearing House (ACH) system, which is free and takes one to three business days.

The one thing that makes a rate "good" regardless of the number

A good rate is one you actually use. If 3.5% is at a bank where you're likely to keep your savings account open and funded, it's better than 5.0% at a bank you'll abandon after six months because the website is confusing or customer service is unreachable. The best rate is the one that fits your habits and needs, not the one that looks best on a spreadsheet.

That said, don't confuse convenience with inertia. If you've never checked what other banks offer, you're almost certainly earning less than you could. Spend 20 minutes comparing rates at three banks. If you find something 0.5% or higher above what you're getting now, open an account and move the money. You'll earn more with no risk and no ongoing work.

Frequently Asked Questions

Is 3.5% APY better than keeping money in a checking account?

Yes. Most checking accounts pay 0.01% or nothing at all. Moving money to a savings account at 3.5% means your balance grows instead of staying flat. The difference compounds over time, so even modest balances earn noticeably more in a savings account.

Should I move my money if I find a bank offering 4.0% instead of 3.5%?

If the 4.0% account has no minimum balance, no monthly fees, and FDIC insurance, yes. The 0.5% difference earns you $50 per year on a $10,000 balance—not huge, but real money for a few minutes of work. The transfer takes one to three business days and costs nothing.

What if the bank offering 3.5% is my main bank where I have checking?

You don't have to move your checking account. Open a savings account at a higher-rate bank and keep your checking where it is. Many people maintain accounts at two or three banks for different purposes. Transfer money to the high-rate savings account and leave your checking alone.

Can a bank lower my rate after I open the account?

Yes. Banks can change savings rates at any time, though they usually give notice. If your rate drops significantly, you can move your money to another bank. This is why checking rates periodically (every few months) makes sense—you want to know if your rate has fallen below what's available elsewhere.

Is a promotional rate worth switching for?

Only if the promotional period is long enough to matter and the standard rate after it expires is still competitive. A 5.0% rate for three months, then 0.5% after, is not worth switching for. A 4.5% rate for 12 months on a bank that also offers 3.5% standard is worth considering, especially if you plan to keep the account open long-term.
