BMO Alto is a high-yield online savings account with no monthly fees and no minimum balance requirement
BMO Alto is an online-only savings account run by BMO Financial Group. It has no monthly maintenance fee, no minimum opening deposit, and no balance requirement to earn interest. The account earns interest on every dollar you hold, and that rate changes based on market conditions—it is not locked in. You can withdraw money anytime without penalty, though transfers out take one to two business days through ACH.
The main trade-off is that BMO Alto has no physical branches. You cannot walk into a bank, deposit cash, or speak to someone in person. All deposits must come by transfer from another bank account, mobile check deposit, or direct deposit. If you need to move cash into savings regularly or prefer face-to-face banking, this account may not fit your workflow.
Key Takeaways
- BMO Alto charges no monthly fee, has no minimum balance, and pays interest on all deposits from day one.
- The interest rate is variable and changes with market conditions, so your earnings will fluctuate month to month.
- You can only deposit money by transfer, direct deposit, or mobile check deposit—no cash deposits at branches.
- Withdrawals and transfers out take one to two business days, so this account works best for money you do not need immediately.
- BMO Alto is owned by BMO Financial Group but operates as a separate online bank with no connection to BMO branch accounts.
How the interest rate works and what you actually earn
BMO Alto publishes its interest rate on its website, and that rate applies to your entire balance. The rate is variable, meaning BMO can change it at any time without notice. When the Federal Reserve raises or lowers interest rates, online banks typically adjust their rates within days or weeks. Your earnings move up and down with those changes.
Interest is compounded daily and deposited to your account monthly. That means you earn interest on your interest, though the effect is small in the first few months. If you hold $10,000 and the rate is 4.0% annual percentage yield (APY), you earn roughly $33 per month before the rate changes. The actual amount depends on the exact rate at the time you hold the money.
To know whether BMO Alto's rate is competitive on any given day, compare it to other online savings accounts—Ally, Marcus, Wealthfront, and others publish their rates publicly. Rates shift constantly, so the best account today may not be the best account in three months. If you care about maximizing interest, you may need to move money between accounts as rates change.
Deposits: how money gets in and how long it takes
You cannot deposit cash directly into BMO Alto. Instead, you transfer money from another bank account using ACH (Automated Clearing House), set up direct deposit from your employer, or deposit a check by phone or mobile app. ACH transfers from another bank typically arrive within one to two business days. Direct deposit from your paycheck arrives on the same schedule as your employer's payroll system—usually one to two days before payday.
Mobile check deposit works through the BMO Alto app: you photograph the front and back of a check, submit it, and the funds appear in your account within one to two business days. There is no stated limit on check deposit amount, but BMO may hold large deposits for review.
If you receive cash regularly or need to deposit money the same day, BMO Alto is not a good fit. You would need to deposit cash at another bank first, then transfer it to BMO Alto—a two-step process that delays your money by at least a day.
Withdrawals and transfers: speed and limits
You can withdraw money from BMO Alto anytime without penalty. Transfers to another bank account take one to two business days via ACH. There is no stated limit on how much you can transfer per day or per month, though BMO may flag unusually large or frequent transfers for review.
If you need cash immediately, you cannot get it from BMO Alto directly. You would transfer money to your checking account at another bank, wait one to two business days, then withdraw cash from an ATM or branch. This makes BMO Alto unsuitable as an emergency fund if you need access within hours.
The Federal Reserve's Regulation D once limited savings account withdrawals to six per month, but that rule was suspended in 2020 and has not been reinstated. You can make as many withdrawals as you want, though your bank may close your account if you treat it like a checking account with daily transfers.
Fees, minimums, and account management
BMO Alto has no monthly maintenance fee, no minimum opening deposit, and no minimum balance requirement. You can open an account with $1 and never add another dollar. There are no overdraft fees because the account cannot overdraft—if you try to transfer more than your balance, the transfer simply fails.
BMO does charge fees for certain actions: a wire transfer out costs $15, and a returned check costs $15. These are not common charges if you use ACH transfers and direct deposit, but they exist. There is no fee to close the account.
Account management happens entirely online or through the mobile app. You can view your balance, transfer money, deposit checks, and change your contact information anytime. You cannot call a branch, but BMO Alto offers phone support during business hours.
Who BMO Alto works well for and who should look elsewhere
BMO Alto suits people who have a stable income, receive direct deposit, and want to park money in a savings account without touching it for months. It works well if you already have a checking account at another bank and simply want a higher-yield place to hold savings. The no-fee structure and variable interest rate mean you are not locked into a bad rate, and you pay nothing to hold the account.
BMO Alto does not work well if you need to deposit cash regularly, prefer to bank in person, or need access to your money within hours. It is also not ideal if you want a may provide interest rate—the variable rate means your earnings shrink if the Federal Reserve cuts rates. And if you want to keep all your banking in one place, BMO Alto is separate from BMO's branch network, so you would be managing two different online systems.
For comparison: if you value in-person service and do not mind paying a monthly fee, a traditional bank savings account may suit you better. If you want a may provide rate, a certificate of deposit (CD) locks in a fixed rate for a set term. If you want the highest possible rate and do not mind switching accounts, you may earn more by moving money to whichever online bank has the best rate at any given moment.
How BMO Alto compares to other online savings accounts
Most online savings accounts—Ally, Marcus, Wealthfront, American Express Personal Savings—have similar features: no monthly fee, no minimum balance, variable interest rates, and one to two day transfer times. The main difference is the interest rate, which changes daily. On any given day, one bank may pay 4.5% APY while another pays 4.25%. Over a year, that 0.25% difference adds up, but the gap closes and reopens constantly as banks adjust rates.
BMO Alto's rate is competitive but not always the highest. If earning the maximum interest is your priority, you would need to check rates across multiple banks weekly and move money when another bank pulls ahead. Most people do not do this. If you want a "set it and forget it" account, pick whichever bank has a reasonable rate today and stay there—the difference between 4.4% and 4.5% is small enough that switching costs (time, attention) usually outweigh the gain.
BMO Alto's main advantage over some competitors is that it is backed by BMO Financial Group, a large established bank. If you already use BMO for checking or other services, the name recognition may matter to you. Its main disadvantage is that it has no physical branches, which matters only if you need in-person service.
Frequently Asked Questions
Can I link BMO Alto to my BMO checking account?
BMO Alto is a separate online bank, not connected to BMO's branch checking accounts. You can transfer money between them, but they are managed through different systems. If you have a BMO checking account, you would transfer money from that account to BMO Alto using ACH, just as you would with any other bank.
What happens if interest rates drop?
Your interest rate will drop with them. BMO can lower the rate anytime without notice. Your balance stays safe, but your monthly earnings shrink. If rates fall significantly, you may want to compare BMO Alto's rate to other banks and move your money if another account offers more.
Is my money safe in BMO Alto?
Yes. BMO Alto is FDIC-insured up to $250,000 per account holder. If BMO fails, the FDIC covers your balance. The account itself is secure—you access it through a username, password, and optional two-factor authentication. Your money is not at risk from the bank's failure or from typical fraud.
Can I use BMO Alto as my main checking account?
No. BMO Alto is a savings account, not a checking account. It has no debit card, no check-writing, and no bill pay. You cannot use it to pay bills or make everyday purchases. It is designed to hold money you want to keep separate and earn interest on.
How do I close the account if I change my mind?
You can close BMO Alto anytime by transferring your balance out and requesting account closure through the app or by phone. There is no fee or penalty. BMO will send you a confirmation once the account is closed.
