3.40% APY is middle-of-the-road right now, not the best available
A 3.40% annual percentage yield sits roughly in the middle of what online banks are offering as of late 2024. You can find rates higher than this—some online savings accounts pay 4.50% to 5.35%—and you can find rates lower, especially at brick-and-mortar banks, which often pay 0.01% to 0.50%. Whether 3.40% is "good" depends on what you're comparing it to and what you're using the account for.
The real question is not whether 3.40% is objectively good, but whether it's better than your other options. If your current savings account pays 0.05%, then 3.40% is a significant upgrade. If you can open an account at another online bank paying 4.75%, then 3.40% is leaving money on your table. The difference between 3.40% and 4.75% on $10,000 is roughly $135 per year—not enormous, but real.
Key Takeaways
- 3.40% APY is competitive with many online banks but not the highest rate currently available; some banks pay 4.50% or more.
- The difference between 3.40% and a higher rate compounds over time, so comparing rates across banks before moving money is worth the effort.
- APY rates change frequently and are set by each bank independently, so a rate that is good today may not be good in six months.
- For money you need to access within a year or two, the difference in APY matters less than for money you plan to leave untouched for years.
How to compare 3.40% to what's actually available
The fastest way to know whether 3.40% is competitive is to check what other online banks are paying right now. Sites like Bankrate, DepositAccounts, and NerdWallet list current rates from multiple banks and update them regularly. Look specifically for "high-yield savings accounts" or "money market accounts"—these are where the higher rates live. Traditional savings accounts at major banks (Chase, Bank of America, Wells Fargo) typically pay far less, often under 0.50%.
When you compare, look at the APY, not the interest rate. APY accounts for compounding—how often the bank adds interest to your balance—so it's the true number that matters. Also check whether the rate requires a minimum balance or has any restrictions. Some banks offer 4.75% APY but only on the first $25,000; money above that earns less. Read the fine print before you move your money.
Why rates change and what that means for your decision
Banks set their own savings rates based on what the Federal Reserve does with its benchmark interest rate. When the Fed raises rates, banks usually raise savings rates too. When the Fed cuts rates, banks cut savings rates. This means a rate that is good today might drop to 2.80% in six months if the Fed cuts rates. Conversely, if the Fed raises rates, you might see 3.40% climb to 3.80% or higher.
This matters because it affects how long you should lock in a rate. If you think rates are about to fall, moving money to a 3.40% account now protects you. If you think rates are about to rise, you might wait a few weeks. Neither prediction is reliable, but the point is that "good" is partly about timing. A rate that looks mediocre today might look generous in a year if the Fed cuts rates sharply.
The math: how much difference 3.40% actually makes
The real test of whether a rate is good is whether the extra money matters to you. Here's what 3.40% earns on different balances over one year, compared to a typical brick-and-mortar bank paying 0.05%:
| Balance | Earnings at 3.40% APY | Earnings at 0.05% APY | Difference per year |
|---|---|---|---|
| $5,000 | $170 | $2.50 | $167.50 |
| $10,000 | $340 | $5 | $335 |
| $25,000 | $850 | $12.50 | $837.50 |
| $50,000 | $1,700 | $25 | $1,675 |
If you have $10,000 sitting in a savings account, moving it from 0.05% to 3.40% puts an extra $335 in your pocket over a year. If you have $50,000, the difference is $1,675. That's real money. But if you have $2,000, the difference is $67—still worth doing, but less urgent.
When 3.40% is good enough, and when you should look elsewhere
3.40% is good enough if: you're moving money from a traditional bank that pays almost nothing; you value convenience and trust the bank offering 3.40%; or you have a small balance where the difference between rates is a few dollars per year. It's also reasonable if you're using the account for a specific goal in the next year or two, since the compounding effect is smaller over short periods.
You should look elsewhere if: other banks are paying 4.50% or more and you have $10,000 or more to deposit; you plan to keep the money in savings for three years or longer, because the compounding difference grows; or you're moving money specifically to maximize returns. The effort to open a new account at a higher-paying bank takes 10 to 15 minutes online, and the extra earnings over a year or two usually justify that time.
What happens to your rate after you open the account
Most banks reserve the right to change savings rates at any time. This means if you open an account at 3.40%, the bank can drop it to 3.10% next month if they choose. You're not locked in. However, you're also free to move your money to another bank if the rate drops and you find a better offer elsewhere. There's no penalty for closing a savings account and moving your balance.
Some banks are more aggressive about cutting rates than others. Online banks that compete heavily on rate tend to keep rates higher longer, because losing customers to competitors hurts. Traditional banks often cut rates faster because they have less pressure to compete. If you're choosing between a 3.40% account at an online bank and a 3.40% account at a traditional bank, the online bank is more likely to maintain the rate.
Frequently Asked Questions
Is 3.40% better than keeping money in a checking account?
Yes. Most checking accounts pay 0% or close to it, so 3.40% is a significant upgrade. If you have money you don't need to access frequently, moving it to a savings account earning 3.40% is a straightforward way to earn more without taking any risk. The tradeoff is that savings accounts typically limit how many times per month you can withdraw money.
Should I move my money if my current bank pays 3.40% but another bank pays 4.75%?
It depends on your balance and how long you plan to keep the money there. On $10,000, the difference is roughly $135 per year. If you have $50,000, it's $675 per year. If the higher-paying bank is reputable and FDIC-insured, the extra earnings usually justify opening a new account. Moving money takes 10 to 15 minutes and costs nothing.
Will 3.40% stay the same, or will it drop?
Banks can change rates at any time, so 3.40% is not may provide to stay. If the Federal Reserve cuts interest rates, most banks will cut savings rates too. You can move your money to another bank if the rate drops and you find a better offer, with no penalty.
Is a savings account the best place for money I want to grow?
Savings accounts are safe and liquid, but they're not the highest-earning option. Certificates of deposit (CDs) often pay more than savings accounts, though your money is locked up for a set period. Money market accounts sometimes pay slightly more than savings accounts. For money you won't need for years, a CD might earn more, but you lose access to the money until the term ends.
How do I know if a bank offering 3.40% is trustworthy?
Check whether the bank is FDIC-insured, which protects your deposits up to $250,000 if the bank fails. You can verify this on the FDIC's website. Also read recent customer reviews on independent sites like Trustpilot or the Better Business Bureau. Banks offering unusually high rates sometimes have poor customer service or hidden fees, so it's worth checking before you move your money.
