I pretty much emptied my savings accounts donating to Twitch streamers and this year I'm trying to build it back up a bit before property taxes hit. I'm using Capital One 360 Savings which is currently 0.30% APR. It seems pretty low so let's look around a little bit.

Wells Fargo: 0.01% savings
San Mateo Credit Union: 0.91% premium checking to $50k, 0.50% digital savings to $20k

Web search... bet seems to be about 0.60% stable (i.e. rate doesn't go down as your deposit increases). Mostly for banks I've never heard of.

So it looks like best comfortable choice is a digital savings account at SMCU.
