Growth Money Market FAQs
A money market account is a type of savings account, and it functions in much the same way as other deposit accounts. You'll earn interest on the money that you save in your account. Plus, you get the flexibility to withdraw money from the account when you need to.Footnote 2
This will depend on how much money you deposit. Our Growth Money Market account offers competitive tiered interest rates; as your balance hits each tier balance, you then qualify for the interest rate associated with that tier. Plus, you can get an even higher interest rate when you pair your Growth Money Market account with a BMO Relationship Checking account that meets the qualifying activity requirement.Footnote 1

Definitions of Capitalized Terms
Footnote 1 detailsThe Annual Percentage Yield (APY) is accurate as shown. Growth Money Market is a variable rate account. Interest rates and APYs may change daily after the account is open. For accounts that have more than one tier, the interest rate corresponding to the highest tier into which the collected balance falls will be paid on the entire collected balance. At any time, interest rates and APYs offered within two or more consecutive tiers may be the same. In this case, multiple tiers will be shown as a single tier. The following collected balance tiers and corresponding standard APYs are effective as of the date shown and are subject to change at our discretion at any time: 0.05% for balances less than $5,000, 0.55% for balances between $5,000 and $24,999.99, 0.95% for balances between $25,000 and $99,999.99, 1.97% for balances between $100,000 and $249,999.99, and 2.68% for balances of $250,000 or more. We may offer higher interest rates when you are an Account Owner of both a BMO Relationship Checking account that has qualifying activities and a Growth Money Market account. Explore the Growth Money Market account disclosure for details. The following collected balance tiers and corresponding APYs for Account Owners with a BMO Relationship Checking account that has qualifying activities are effective as of the date shown and are subject to change at our discretion at any time: 0.30% for balances less than $5,000, 0.80% for balances between $5,000 and $24,999.99, 1.20% for balances between $25,000 and $99,999.99, 2.22% for balances between $100,000 and $249,999.99, and 2.94% for balances of $250,000 or more. Interest is calculated on the entire collected balance daily at the rate in effect for that balance tier. You must maintain the required minimum collected balance for each tier to earn the APYs disclosed. A periodic rate is applied on the collected balance in the account daily. Interest is compounded daily on the collected balance and credited to the account monthly on the statement period date. Checks you deposit into your account begin to earn interest on the Business Day we receive credit for them. Fees and withdrawals may reduce earnings. For account and fee information or current interest rates, visit bmo.com or call 1-800-546-6101.
