From Birds of a FIRE
When I was a kid my savings account returned nothing. I think it was like .01%.
When I went to college, I got a savings account at the bank near my college since my old bank wasn’t in that part of the country and I needed to access an ATM/branch occasionally.
It wasn’t until I saw a post somewhere about high-yield savings accounts that I realized different banks paid different levels of interest on savings accounts. Tell me again how personal finance is common sense.
