I Bonds rates next month will likely be in the 9 percent range given recent inflation. An attractive guaranteed rate for any cash not being used for at least a year. Certainly better than a savings account or other options. Any funds pulled out after a year that aren't in for five years, give up one quarters worth of interest. 

One thing of note, one can only do $10,000 per person in a calendar year electronic purchase wise. And another $5,000 on top of that if you are using tax return funds. Consider your situation before purchase of course. I'l be buying more soon, already have some of the 7.12% ones. Interest compounds semi annually and the interest rate updates every six months:

I like to do what I can to have a plan for our household. Once I'm informed, I formulate a plan and execute on it accordingly. Watching endless videos and reading endless articles does nothing for me. This goes for any subject I have no control over. Back to enjoying my life. The question becomes where should my money be and why during a particular period of time.
