re: How much money do you put in savings every paycheck?

15% into company stock (given a 15% discount w/ no lock up, converted into cash before every earnings announcement)
2.25% from stock purchase discount
6% contribution to Roth 401k
7.5% company match

That brings it to an effective rate of 30.75%, with a personal savings rate of 21%

I also live only on my salary and don't include my bonus into any of my plans, so 100% (20% of my salary) goes into savings.

If you count my bonus in the equation, it's 42.29%.

However, I always seem to be a couple hundred bucks a month over, hurting cash savings, so it may be a little under 40% in reality.
