Implicit in the savings rate is also your spending rate (and your "LBYM factor").
This is precisely why I calculate it as part of my semi-annual "analysis". While I am certain that I could establish a standard of living well below my means and never change it, life is about having fun, too. As I progress and my and my wife's earnings increase, we allow our standard of living to increase a little bit. Knowing my savings rate, and trying to ensure that it tracks upwards over time and with raises gives us a numerical "benchmark". It's not something where we have a goal or something I brag about. Rather, it's just a measure to help us understand how well we are meeting the mark of LBOM, and gives an easy-to-calculate indication of when we might be straying. If we see a dip in our savings rate, we can figure out why.
That said, our savings are on autopilot, so in order for our savings rate to dip either (1) I have to go in and actually change an autodraft; or (2) our income increased and thus the dip is an indicator that we need to increase our savings accordingly. So, I do think calculating savings rate has some value.
