Which credit union offers 4% on all money with them? I know of a few CUs that will offer much higher interest on the first X dollars. Ex: inspiruscu.org
There is usually a cap on those high interest rates - at my CU, its $25k. They pay 2% though, not 4% - it used to be a pretty good deal, but these days its easy to get a money market fund elsewhere that pays more than that with no maximum.
I don't know of any that offer 4% on all money, but one near me offers 3% on the first $3k. After $3k though, you might as well get a CD or invest it in something higher return than a checking account.
Yeah when I started looking at one of my local credit unions I almost jumped at the 10% interest rate before I realized it was only 10% on the first $1k then less than 1% on everything after that
I hear this argument a lot, but is a checking account really the best place to invest your money? In my view it's better to get 10% on $1k than 0.1% on unlimited, and then take anything over that $1k (or whatever you need in your checking account) and put it in a real investment.
Remember we're talking about checking accounts, not mutual funds. It's not a real investment. You might as well get something even if it's small.
