I started tracking a few money market fund rates a while back. My numbers are attached for Fidelity, T Rowe Price and Vanguard. I started doing this because I found that fund companies were taking advantage of their clients not being informed about the rates they could easily get.
What I found is that Vanguard pays consistently higher rates than either Fidelity or T Rowe Price.. Also, Vanguard raised the rate they pay much more quickly than the others.
If you are holding cash, but not watching, fund companies will take full advantage of you. Bank's did it for decades. But, with technology, rates are so easy to compare on-line. People are moving funds away from banks now, but fund companies will take you to task too if you are not watching.
While the rates can be compared, many people are just plain lazy and let institutions reap the benefit to their disadvantage.
Money in investing is often made at the margin. If you're not watching, you're likely losing returns.
Be smart, be well-read, be aware and be successful.
