There is no limit as to how much cash you can optimize using Max.


By default, Max helps you keep your balances below the FDIC insurance limit at each bank. However, you may elect to exceed the FDIC limit by changing your settings on a bank-by-bank basis at any time.


Some online banks have established maximum balance limits. Max takes each bank's limits into account when proposing transfers for your monthly optimization or Intelligent Funds Transfers (SM).


Below you'll find a summary of the balance limits at each online bank (as of 4/2021):
