BMO's branch Savings Builder account pays 0.01% APY — annual percentage yield, the yearly interest rate including compounding — while leading online banks pay 3.10%-3.90% APY. BMO's own online options close the gap, with nationwide Online Savings at 3.00% APY and BMO Alto at about 4.10% APY. For readers chasing bank bonuses, the account type matters more than the bank name. A branch savings account and an online savings account from the same bank can pay very different rates.

What BMO pays in branches
BMO's Savings Builder account pays 0.01% APY in branches, according to Money Crashers. The same report lists Growth Money Market at 0.05% to 2.50% APY and CD specials at 3.00% to 3.35% APY.
That 0.01% savings rate sits far below the FDIC national average of 0.38% APY reported for October 2026, according to Finder in its Finder BMO rate comparison. A branch saver earns almost no interest unless the money moves to a money market tier or a CD special.
What BMO pays online
BMO's nationwide Online Savings account pays 3.00% APY on balances from $0.01 with no stated minimum, according to Hustler Money Blog. It is a separate product from the branch savings account.
BMO Alto, BMO's online-only division, pays about 4.10% APY with no monthly fee, no minimum opening deposit, and no minimum balance, according to NerdWallet in its NerdWallet BMO Alto review. That puts BMO Alto above BMO's branch and nationwide online savings rates.
How outside online banks compare
Leading online high-yield accounts paid 3.10%-3.90% APY as of Oct. 10, 2026, ClearValue Lending reports in its ClearValue high-yield roundup.
The list includes Bask Bank at 3.90%, CIT Platinum at 3.75% on $5,000-plus, Synchrony at 3.55%, and Marcus at 3.50%. SoFi paid 3.30% with direct deposit, while Ally, Capital One 360, and Amex paid 3.10%. The highest advertised offer reached up to 5.00% APY through Axos ONE, limited to new customers for the first six months, according to The Motley Fool.
What to check before you move cash
Advertised APYs are variable and conditional, ClearValue Lending reports. Higher rates often require balance tiers, direct deposit, new-customer status, or short promotional periods before reverting to a lower base rate.
High-yield online accounts pay roughly 10-11 times the national average, worth about $960 extra yearly interest on a $25,000 emergency fund versus a typical branch account, according to Branchspot. Before opening an account, work through this check: Keep branch cash for daily needs and move idle savings to the account with the highest lasting base rate you qualify for.
- Note the base rate that applies after any intro period ends
- Confirm any balance tier, direct-deposit, or new-customer rule
- Match the minimum and access rules to your emergency-fund needs
