re: Suggested % to contribute to youy 401K?

I didn't contribute my first 3 years out of LSU around 2004-2007 since my company didn't match. Bad choice on my part but oh well.

2007-2010 I contributed 6-8%
2010-Present. 8% for a few months, then 10% for some months then 15% for about the past 6.

I'm married with zero kids. I say put in as much as you feel you can.

Edit to add, after the 1st gig 2nd company matched 2% and the current is 3%.
