Title: How to calculate savings rate for the not mathematically inclined
Post by: badassprof on February 15, 2013, 01:48:24 PM
Hi everyone:

Just wondering if someone has some thoughts about the best way to calculate our savings rate. Part of our savings is pretax (401ks) and part of it is a dollar amount from take home. How would you calculate that?  Also, do any of you count employer matches or stock options into savings rates or do you just consider that extra? Thanks.

Probably the wrong question to ask on this forum but does it really matter what your savings rate is?

I reckon a better measure is the concept of "jaws" (think of a big saltwater crocodile). Getting income up and expenses down and progressively growing that gap.

Just for projections, and measuring progress, and setting goals.

In other words, no, not really.

And most importantly bragging

Probably doesn't matter at all.  I have a goal to improve it by a certain percentage per year, so I want to keep better track than I have in the past.

Lol!  I didn't mean to refer to you specifically.

Ha yes i've read the shockingly simple math. But my problem with it is that it is shockingly simple.

What happens if the sharemarket loses 40% in a year? You could have an 80% savings rate and still find yourself going backwards.

You could also end up the other way cutting 3 or 4 more years off your projected retirement date but that is beside the point.

%'s have always been a bugbear for me because it all depends on starting points lowbase/highbase etc etc.

Actual $ values have always mattered more to me, but each to their own

You can't control that.  You can control savings rate.

All that matters is the amount you save. By increasing savings rate it incorporates both earning more and spending less, very powerful tools.

I think we should sticky this post, or add it into the 'case study' thread.  I knew it existed so I found it with a simple search, but it may be useful to other people!
