The M1 Spend checking account offered by M1 Finance offers a 3.30% APY on Checking. But this rate can change, so it’s important to check the current rate on the M1 Finance website.  The M1 Spend account may not be as high as some other online banks, but it’s still a good option for those looking for a fee-free checking account.  It also comes with convenient features, such as ATM fee reimbursements and cashback rewards on purchases.
