3.70% APY is competitive but not the highest rate available
Whether 3.70% APY is good depends on what else is available at the moment you're looking, and what type of account it is. High-yield savings accounts at online banks regularly offer rates between 4.00% and 5.35% APY. If you're seeing 3.70% at a traditional bank branch, it's likely below what you could get elsewhere. If it's from an online bank, it's probably a few months behind the current market.
APY rates move constantly. The Federal Reserve sets a target range, and banks adjust their rates in response. A rate that was excellent six months ago may be middle-of-the-road today. The only way to know if 3.70% is good for you is to check what other banks are offering right now, then decide whether the extra 0.5% to 1.5% elsewhere is worth switching.
Key Takeaways
- Online banks typically offer higher APY than brick-and-mortar banks, often by 1% or more on the same type of account.
- A 3.70% rate at a traditional bank is usually below market; the same rate at an online bank is usually a few months old.
- The difference between 3.70% and 4.50% on $10,000 is about $80 per year in actual interest earned.
- Money market accounts and certificates of deposit sometimes offer higher rates than savings accounts, but with different access rules.
- Your bank's rate can change at any time, so checking competitors every few months helps you decide whether to move your money.
How to compare 3.70% to what's actually available
The fastest way to see current rates is to visit the websites of online banks directly. Banks like Marcus, Ally, American Express Personal Savings, and Discover all publish their current APY on their homepage. You can see the exact rate without logging in. Write down the rates you find, note the date you checked, and compare them side by side.
Then check your own bank's website. If you have money at a Chase branch or Bank of America, look up their current savings account rate. The gap between what you're earning now and what you could earn elsewhere is your real answer to whether 3.70% is good. If the gap is less than 0.25%, the hassle of moving may not be worth it. If it's 0.75% or more, the math usually favors switching.
What the difference actually costs you in dollars
APY percentages can feel abstract. Here's what they mean in real money. On $10,000 in savings:
| APY Rate | Interest Earned in One Year | Difference from 3.70% |
|---|---|---|
| 3.70% | $370 | — |
| 4.25% | $425 | +$55 |
| 4.75% | $475 | +$105 |
| 5.25% | $525 | +$155 |
On $50,000, those differences multiply by five. On $100,000, by ten. If you have a substantial balance sitting in a 3.70% account while competitors offer 4.75%, you're leaving hundreds of dollars on the table each year. That money compounds, so the gap grows larger the longer you wait to move.
Why your bank might be offering 3.70% when others offer more
Traditional banks with physical branches typically pay lower rates because they have higher operating costs. They pay rent on buildings, salaries for tellers, and maintain ATM networks. Online banks have no branches, so they pass the savings to depositors through higher rates. This is not a sign that the traditional bank is safer or better—it's just a different business model.
Some banks also offer lower rates to customers who have other products with them, like mortgages or checking accounts. They're betting you won't move your savings because you don't want to manage accounts at multiple institutions. That's a choice you can make, but it's worth knowing the cost.
Money market accounts and CDs might pay more than savings accounts
If you're comparing a 3.70% savings account to other savings accounts, that's the right comparison. But if you don't need to withdraw money frequently, a money market account or certificate of deposit (CD) might pay more. Money market accounts work like savings accounts but sometimes offer higher rates in exchange for a higher minimum balance. CDs lock your money away for a set period—three months, six months, one year, five years—and pay a fixed rate for that entire period.
The tradeoff is access. With a CD, you can't touch the money without paying an early withdrawal penalty. With a money market account, you can usually withdraw, but there may be limits on how many times per month. If you're building an emergency fund that you might need quickly, a regular savings account is the right choice even if the rate is lower. If you're saving for something specific that won't happen for a year or more, a CD might pay 0.5% to 1% more.
When to move your money and when to stay put
Moving money takes time and creates a small administrative burden. You have to open a new account, transfer funds, and update any automatic deposits. It's worth doing if the rate difference is 0.5% or more and you plan to keep the money there for at least a year. If you have $25,000 or more, the math almost always favors moving. If you have $5,000 or less, the annual difference might be $25 to $50, which may not feel worth the effort.
Also consider how long you plan to keep the money in savings. If you're saving for a down payment you'll use in six months, a rate difference of 0.5% costs you about $25 on $10,000. If you're building long-term savings you'll keep for five years, the same difference costs you $250 or more when compounding is included. The longer the timeline, the more the rate matters.
Rates change, so check back periodically
A rate that's competitive today may not be in three months. The Federal Reserve meets eight times per year and can raise or lower its target range. When it does, banks adjust their rates—sometimes within days, sometimes over weeks. A bank that offered 5.35% in September might offer 4.75% in December. This doesn't mean the bank got worse; it means the entire market shifted.
Set a reminder to check rates every three to four months. It takes five minutes. If your current bank's rate has fallen more than 0.5% behind the market average, that's a signal to look at moving. You don't have to move every time rates shift slightly, but staying aware of the gap helps you make intentional decisions rather than letting inertia keep your money in a below-market account.
Frequently Asked Questions
Is 3.70% safe, or is the bank taking on too much risk to offer it?
No. Banks offer different rates based on their business model and funding costs, not because higher rates mean higher risk. Online banks and traditional banks are equally insured by the FDIC up to $250,000 per account. A 5.00% rate at an online bank is not riskier than a 3.70% rate at a branch bank. The difference is operating costs, not safety.
Will my rate stay at 3.70% forever?
No. Banks can change savings account rates at any time without notice. Your rate might stay the same for months or change weekly. When the Federal Reserve raises or lowers its target range, most banks adjust their rates within days or weeks. Check your bank's website periodically to see if your rate has changed.
Should I move my money if the difference is only 0.25%?
Probably not. On $10,000, a 0.25% difference is $25 per year. The time and effort to open a new account and transfer funds usually isn't worth $25. If you have $100,000 or more, the math changes—0.25% becomes $250 per year, which may be worth it. Consider your balance and how much effort the move will take.
Can I lock in a rate so it doesn't go down?
Not with a regular savings account. Rates on savings accounts are variable, meaning the bank can lower them whenever it wants. If you want a may provide rate, you need a CD. You pick the term—three months, one year, five years—and the rate stays the same for that entire period. The tradeoff is you can't withdraw the money early without a penalty.
Is it better to have my savings at the same bank as my checking account?
Convenience and rate are two different things. Having both at the same bank makes transfers straightforward, but it shouldn't cost you hundreds of dollars per year. If your bank pays 2.50% on savings while competitors pay 4.75%, moving your savings to a different bank is usually worth the minor inconvenience. You can keep your checking account where it is and move only the savings.
