It was in comparison to Apple's 4.15% and Wealthfront's 4.3%. So that's .1 - .25%. And I think most would argue that, at max, you should have a year's bills in cash. So that's like $30k - $80k. Assuming standard marginal income tax rate of 30%, that extra interest is $30 - $400, so $21 to $280, and Robinhood's $60/yr loss, so -$39 to $220. Maybe kind of worth it at the high end, but I guess I should also then mention that 4mo T-bills pay 5.17%.
