Open Bank offers low fees and no minimum balance, but limited features compared to traditional banks
Open Bank is an online savings account with no monthly maintenance fee, no minimum opening deposit, and interest paid daily on your balance. It's run by Customers Bank, a Pennsylvania-based FDIC-insured institution, so your money is protected up to $250,000 by federal deposit insurance.
Whether it's a good fit depends on what you need from a savings account. If you want a straightforward place to park money with low friction and no fees, Open Bank works. If you need features like debit cards, check writing, or customer service by phone, you'll need to look elsewhere—Open Bank operates online only and doesn't offer those tools.
The interest rate changes with the market, so the yield you see today won't be the yield you see in six months. Before you open an account, check the current rate against other online banks to see where it stands. Rates shift constantly, and a competitive rate today can become uncompetitive quickly.
Key Takeaways
- Open Bank charges no monthly fee and requires no minimum balance to open or maintain an account.
- Your deposits are FDIC-insured up to $250,000, meaning your money is protected if the bank fails.
- You can only manage your account online or through their mobile app—there are no branches, phone support, or debit cards.
- Interest rates are variable and change based on market conditions, so compare the current rate to other online banks before opening.
- Transfers to and from external banks take one to three business days, which is standard for online savings accounts.
How Open Bank's fees and minimums compare
Open Bank has no monthly maintenance fee, no minimum balance requirement, and no fees for transfers or withdrawals. That removes several friction points that make other savings accounts expensive. If you're coming from a traditional bank that charges $5 to $15 per month just to hold an account, the difference adds up.
Most online savings banks also have no fees—that's the competitive standard now. Where Open Bank stands out is consistency: the fee structure doesn't change based on how much money you have or how often you move it. A $100 balance and a $100,000 balance pay the same zero dollars per month.
The trade-off is features. You won't get a debit card, checkbook, or overdraft protection. If you need to spend money from this account regularly, you'll transfer it to a checking account first, which takes a few days. That delay is intentional—savings accounts are designed to discourage frequent withdrawals, and the slow transfer speed reinforces that.
Interest rates and how they work
Open Bank pays interest daily on your balance, which means the interest compounds every single day rather than monthly or quarterly. Daily compounding gives you slightly more money over time than less frequent compounding, though the difference is usually small unless your balance is large.
The rate itself is variable, meaning Open Bank can change it whenever they want. They typically raise rates when the Federal Reserve raises its benchmark rate and lower them when the Fed cuts. The rate you see when you open an account will not be the rate you earn a year from now—it could be higher or lower depending on what the Fed does.
To know whether Open Bank's current rate is competitive, check it against other online banks like Marcus, Ally, or American Express Personal Savings. Rates shift weekly, and a difference of 0.25% or 0.50% per year matters more on larger balances. On $10,000, a 0.50% difference is $50 per year. On $100,000, it's $500.
What you can and cannot do with Open Bank
You can deposit money by transferring it from another bank account. You can withdraw money the same way—by initiating a transfer to an external account. Transfers typically take one to three business days. You cannot deposit cash, write checks, use a debit card, or visit a physical location.
If you need to move money quickly, the delay matters. If you're saving for a goal six months away and rarely touch the account, the delay is irrelevant. Think about your actual habits: do you move money between accounts often, or do you set it and leave it?
Open Bank has a mobile app and a website where you can check your balance, see your interest earnings, and set up transfers. Customer support is email-only, not phone or chat. If you need to talk to someone immediately, Open Bank isn't built for that.
FDIC insurance and account safety
Open Bank is FDIC-insured through Customers Bank. That means if the bank fails, the federal government guarantees your deposits up to $250,000 per account owner. If you have $50,000 in an Open Bank savings account, all $50,000 is protected. If you have $300,000, the first $250,000 is protected and the remaining $50,000 is not.
The FDIC insurance limit applies per bank, not per account. If you opened two separate savings accounts at Open Bank, they would share the same $250,000 protection pool. If you want to protect more than $250,000, you would need to split it across different banks.
Your account is also protected by standard online security: encryption, two-factor authentication, and fraud monitoring. Open Bank does not hold your money in a way that makes it more or less safe than any other FDIC-insured bank.
When Open Bank makes sense and when it doesn't
Open Bank works well if you want a low-friction savings account with no fees and you don't need to access your money quickly or frequently. It's good for emergency funds, short-term savings goals, or money you're setting aside and not touching for months. It's also a reasonable choice if you already have a checking account elsewhere and just need a separate place to save.
Open Bank doesn't work well if you need a debit card, if you make frequent transfers, if you want phone support, or if you prefer to bank in person. It also doesn't work if you have more than $250,000 to protect, since you'd need to split it across multiple banks anyway.
The best savings account for you depends on your actual behavior, not on marketing claims. If you're comparing Open Bank to other options, write down what you actually do with your money—how often you move it, whether you need a card, whether you ever call customer service—and match that to the account's features.
How to open an account and what to expect
Opening an Open Bank account takes about 10 minutes online. You'll need your Social Security number, a valid ID, your current address, and an external bank account to link for transfers. Open Bank will verify your identity and may ask for additional documents depending on what their system flags.
Once your account is open, you can transfer money from your linked bank account immediately. The money will arrive in one to three business days. You'll start earning interest right away on whatever balance you have, even if it's $1.
If you change your mind, you can close the account anytime with no penalty. Transfer your balance out, request account closure, and you're done. There's no lock-in period and no exit fee.
Frequently Asked Questions
Can I deposit cash into an Open Bank account?
No. Open Bank is online-only and doesn't accept cash deposits. You can only fund the account by transferring money from another bank account. If you need to deposit cash, you'd have to deposit it at your primary bank first, then transfer it to Open Bank.
What happens to my interest if the Fed cuts rates?
Your interest rate will likely drop. Open Bank adjusts rates based on market conditions, and when the Federal Reserve lowers its benchmark rate, online banks typically lower their savings rates within days or weeks. Your balance stays safe, but you'll earn less interest going forward.
Is Open Bank FDIC insured?
Yes. Open Bank is FDIC-insured through Customers Bank, and your deposits are protected up to $250,000. If you have more than $250,000, only the first $250,000 is covered by FDIC insurance at this bank.
How long do transfers take?
Transfers between Open Bank and external accounts typically take one to three business days. Weekends and holidays don't count as business days, so a transfer initiated on Friday may not arrive until Tuesday. This is standard for online banks.
Can I get a debit card with Open Bank?
No. Open Bank doesn't issue debit cards. If you need to spend money from this account, you'll transfer it to a checking account first. That's by design—savings accounts are meant to discourage frequent spending.
