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%.

6% in 401k, company matches that amount.
Another 5% in Roth. And another $500 in savings each month, unfortunately with me getting some property ready to build a house I am going into the savings constantly. Put $20 a month for each kid in 529 college fund also.

Yearly max which I think is $17k?

My company matches $ for $ up to 9%, so that's what I contribute.

Do you have adequate insurance on your assets?
Do you have 6-12 months of your gross annual income saved in a liquid accout?
What is your consumer-debt load?
Age?
Company match amount?

*Remember that any of your money that you deposit into a qualified retirement plan law account will be taxed at ordinary income tax levels to be determined at that point in time.

I'm upping mine from 10% to 15% in a week or two. Hopefully I'll have to make a big adjustment come raise time. I'm probably just being overly optimistic about recently getting my MBA.

I'm at 15% with a 5% company match and 4% lump sum each year. As soon as the wife's student loans are paid off, I'll be maxing it out.

I really need to get back into the habbit of contributing to a Roth IRA.
