These deals just seem like too much effort to me.
Okay, so - instead of a "regular" 1% savings account*, you get this 3% account. An extra $300/year in interest (pretax) - lets say $255 post-tax, if you are in the 15% bracket. In exchange, you have to:
Perform 10 debit card transactions a month. That's 120 transactions. Lets say, average of $10 per transaction. $1,200 - for which, you should be averaging 2% return on credit cards** = $24 foregone
So, your $255 is now $231
4 logins per month = 48 logins
..and woe to you if you forget to do all your logins or transactions. No 3% for you!
So, 168 individual actions (not counting account setup, account closing, additional 1099, time on "okay, am I at 9 transactions or 11 this month?" et cetera) - for $231
$1.38 per action. I'm sure I can come up with something better to do with my time. Churning rewards cards comes to mind, or spending a few hours on a side gig. Or Craigslisting junk from my house.
*Math simplicity. Maybe it's 0.85% Doesn't really matter.
** Quicksilver is 1.5% back on everything, and there are plenty of rotating category or category bonus cards which yield 2-5% on specific transactions. For example, I get back 3-5% on gasoline, I make my big Home Depot purchases in the 2nd quarter with 5% back, et cetera.
