Update 5/24/23: M1 is discontinuing their checking account in favor of a new savings account being launched which currently boasts 5% APY. Do note, this yield is only for M1 Plus members which costs either $10/month or $95/year. The free trial of M1 is now only three months free. Without M1 Plus the interest rate is currently 1.50% APY. See other options in our post on Best High Yield Savings Accounts.
Original Post:
M1 Finance offers an upgraded ‘M1 Plus’ membership which offers 1% APY on balances in the checking account. It also offers 1% on swiped/online debit card purchases; that might be useful as well on certain types of transactions (?).
While M1 Plus membership costs $125 per year, they do offer your first year free. Might not be worth the $125 fee, but some people will find it worthwhile to sign up to get the 1% APY rate. Far as I can tell, there’s no limit on how much earns that rate (just remember the $250,000 FDIC limit). That compares to other high-yield accounts which mostly run more in the .5%-.75% range at the time of this writing.
M1 Spend checking accounts are furnished by Lincoln Savings Bank, Member FDIC. M1 Visa Debit Card is issued by Lincoln Savings Bank, Member FDIC.
