What are some investment tips for a 401K account?

I contribute 13% of my paycheck to my 401K. Is that enough if my salary continues to increase each year? I work in the IT industry.

Go with the higher risk/higher reward investments offered by your employer early in your career and then go safer later in your career when you get closer to retirement.

And open a Roth IRA every year!

Yeah, that's pretty standard. Most people I know put in 5-8%. Trick is to find whatever funds/stocks/whatever that have a good long-term investment rate and just let your money sit there. Set it when you start then don't look at it again for at least six months...

Only contribute to the 401k to max out the company match, then max out with a Roth IRA. If you still have some money to put away after that, check out I Bonds.

Contribute as much as you can to it especially if your company matches a percentage of it.

ERISA laws, and your company will inform you how much that is, it depends on your income. After you reach 100k salary per year, there's a max pre-tax contribution and a max after-tax contribution.

Look for available funds offered through your employer's 401K that say "Balanced Fund". These funds have good diversification and you can feel comfortable that your contributions will get goot 8 to 10% return over the life. Also, look at fees charged as sometimes managed mutual funds will have hefty management fees.
