There is no minimum balance to keep Boost Account, and there is no low-balance fee or inactivity fee. The minimum initial transfer required to open any Tellus savings-related Account - including Boost, Reserve, etc - is $100.  Interest and rewards are calculated daily at 12AM PST and Tellus does not pay fractional pennies. If your balance is low enough that a whole penny is not earned, rewards will not be paid that day.

Tellus is not a bank. Tellus is not FDIC-insured.
