The rates you'll find depend on the bank type and how you search
Savings account interest rates vary widely — from nearly zero at some big national banks to 4% or higher at online banks and credit unions. The difference comes down to how much it costs the bank to operate. A bank with no physical branches has lower overhead, so it can pay you more interest on your savings. A bank with thousands of branches and staff has higher costs, so it pays less.
The highest rates are almost always at online banks, followed by credit unions, then traditional brick-and-mortar banks. But the highest rate is only useful if the bank is safe and the account fits how you actually save. A rate that drops after three months, or an account that charges fees, can wipe out your gains.
Key Takeaways
- Online banks typically offer the highest rates because they have lower operating costs than banks with physical locations.
- Credit unions often pay competitive rates and may offer better terms if you meet their membership requirements.
- The rate you see advertised may change after a promotional period, so read the full terms before opening an account.
- Compare the annual percentage yield (APY) across banks, not just the interest rate, because APY includes how often interest compounds.
- Check that any bank is insured by the FDIC (for banks) or NCUA (for credit unions) so your money is protected up to $250,000.
How to compare rates across different bank types
Start by checking three categories: online banks, credit unions, and traditional banks. Online banks like Marcus, Ally, and American Express Personal Savings typically post their current rates on their homepage. Credit unions list rates on their websites, but you can also call and ask — many credit union staff are trained to explain rates over the phone. Traditional banks (Chase, Bank of America, Wells Fargo) usually show rates on their websites, though you may need to click through to the savings account product page.
When you compare, look at the APY, not just the interest rate. APY tells you the real return after the bank compounds interest — meaning adds earned interest back into your account so it earns interest too. Two banks might advertise the same rate, but if one compounds daily and one compounds monthly, the daily one will give you slightly more. The difference is small, but it adds up over time.
Write down the APY, any fees, and the minimum balance required for each account you're considering. Some banks waive fees if you keep a certain amount in the account. Others charge monthly maintenance fees that can cancel out months of interest on a small balance.
Online banks usually offer the highest rates
Online banks can pay higher rates because they don't maintain physical branches, employ fewer staff, and operate with lower overhead. They pass those savings to customers through better interest rates. Most online banks also have no monthly fees and no minimum balance requirements, which makes them straightforward to compare.
The tradeoff is that you cannot walk into a branch or speak to someone in person. You manage your account through a website or mobile app, and you contact customer service by phone, email, or chat. If you're comfortable with that, online banks are usually the best choice for rate shopping.
One thing to watch: some online banks offer a promotional rate for the first few months, then drop the rate significantly. Read the terms carefully. If the rate drops after three months, calculate what your interest will be at the lower rate before you open the account.
Credit unions may offer competitive rates and member benefits
Credit unions are nonprofit organizations owned by their members. Because they don't aim to make a profit, they often pay higher interest rates than traditional banks and charge lower fees. Some credit unions offer rates that match or beat online banks.
The catch is that you have to be a member to open an account. Membership requirements vary — some credit unions are open to anyone who lives or works in a certain area, others are only for employees of a specific company or members of a specific organization. You can search for credit unions near you at CO-OP or Allpoint, which are networks that let credit union members use ATMs nationwide for free.
If you already belong to a credit union or can join one, it's worth checking their savings rates. Credit union staff can often explain your options over the phone, which is helpful if you're new to banking.
Traditional banks pay lower rates but offer in-person service
Banks like Chase, Bank of America, and Wells Fargo typically pay lower interest rates on savings accounts — sometimes less than 0.5% APY. The reason is their business model: they have thousands of branches, thousands of employees, and high operating costs. They make money by lending out deposits at higher rates, so they don't need to pay depositors as much to attract savings.
The advantage of a traditional bank is that you can walk into a branch, speak to someone face-to-face, and handle complex transactions in person. If you value that service, or if you already have a checking account at a traditional bank, it may be worth staying there even if the savings rate is lower. But if your only goal is to earn interest on savings, a traditional bank is rarely the best choice.
Watch for promotional rates and hidden terms
Some banks advertise a high rate for a limited time to attract new customers. The rate might be 4.5% for the first three months, then drop to 0.5% after that. If you're planning to keep money in the account for years, that promotional rate doesn't help much. Always read the full terms and conditions, not just the advertised rate.
Also check whether the rate applies to your whole balance or only to a portion of it. Some accounts offer a high rate on the first $25,000, then a lower rate on anything above that. Others have no limits. The terms matter as much as the headline number.
If you find an account with a great rate, open it. But set a reminder to check the rate again in six months. Banks change rates frequently, and what's the best option today might not be in a few months. Switching accounts is free and takes about 15 minutes, so don't feel locked in.
Make sure the bank is insured and safe
Before you move money to any bank, confirm it's insured by the FDIC (Federal Deposit Insurance Corporation) if it's a bank, or the NCUA (National Credit Union Administration) if it's a credit union. This insurance protects your money up to $250,000 per account if the bank fails. You can check FDIC insurance status at the FDIC's BankFind tool on their website, or search for the bank's name and "FDIC insured." For credit unions, search the NCUA's credit union locator.
If a bank is not FDIC insured, do not put money there, no matter how high the rate is. The rate is only good if your money is safe.
Frequently Asked Questions
Can I move money between savings accounts if I find a better rate?
Yes. You can open a new account at any bank and transfer money from your old account to the new one. The transfer usually takes one to three business days. There's no penalty for switching banks, and you can keep the old account open or close it. Many people keep multiple savings accounts at different banks to take advantage of different rates or features.
Why do some banks pay almost no interest?
Banks with high operating costs — physical branches, many employees, expensive advertising — need to keep more of the interest they earn to cover those costs. They also assume many customers won't shop around, so they don't need to offer competitive rates to keep deposits. Online banks and credit unions have lower costs, so they can afford to pay you more.
Is a high rate worth switching banks if I have a checking account there too?
That depends on how much you value convenience. If you use your bank's checking account frequently and value in-person service, the cost of a lower savings rate might be worth it. If you rarely visit a branch and mostly use your phone or computer, you'll probably save more money by switching to an online bank with a higher rate. Do the math: calculate how much extra interest you'd earn in a year at the higher rate, then decide if that's worth the switch.
What if the rate drops after I open the account?
Banks can change rates at any time, and they often do. If your rate drops and you find a better one elsewhere, you can open a new account and move your money. There's no penalty for leaving. Some people move their savings to a new bank every year or two to keep up with the best available rates.
Do I need a minimum balance to get the advertised rate?
It varies by bank. Some banks pay the advertised rate on any balance, no matter how small. Others require you to keep a certain amount — often $500 or $1,000 — to earn the full rate. If your balance drops below the minimum, the rate might drop too. Always check the terms before opening an account, and ask what happens if your balance falls below the minimum.
